First of all, all excellent questions, I am no POR15 expert but I have used it a few times now.

I have not seen mine turn purple, but I had it go blotchy, meaning I bought the glossy type and painted my '68 Mustang engine bay with it (two coates as per instructions) and when it all was said and done and dry, some spots were shinny and some were flat and dull. So I called the company up and they said sometimes it just does that? Say What?! Quote:

Re: Restoring Rusty
POR 15 has no UV protection so it will discolor if exposed to UV over time. Topcoat it with regular paint of your choice if it's going to see sunlight.

Re: Restoring Rusty - New Aluminum Radiator Leak
3 Attachment(s)
So this $273 Northern aluminum radiator I bought on Amazon exactly 1 year ago just made it one year and sprung a leak. So a leak after 10,000 miles, lame
leaks about 1/2 a gallon a day |
Re: Restoring Rusty
Sorry to see that, but I feel your pain. I bought one from LMC a couple years ago for my '78 and had the same thing happen. I returned it and bought one from NAPA (not aluminum). That was 7 or 8 years ago and no problems.

so took the original brass/copper radiator for a drive the other day to Sacramento Radiator Service shop, they said it would cost more money to get it re cored than to just buy a new one for $369 bucks, they also offered a cheap new replacement for $139
man that was too rich for my blood especially around this time of year (ie Christmas) so I drove over to another shop for a second opinion and just for the heck of it, at Ideal Radiator (the owner is 90 years old by the way and has done this for a long time) so the younger lady running the front office was super nice and explained everything that was wrong with my old rad and also confirmed a rebuild would be over $400 so I ended up buying a cheap plastic and aluminum one from her for $114 a RadCool brand?, I figured at that price I can take my chances and or buy myself some time, she convinced me if I change the radiator cap once a year this one will last me a long time, we shall see.... we will be installing this one tomorrow on Saturday, pics to follow |
Re: Restoring Rusty
I had my original rad re-cored locally with a high-density 4-row core a couple years ago. It was as pricey as your quotes, but it's holding dandy.
As an aside - I fabricated an all-aluminum radiator using a good core that had a cracked plastic tank, and I made my own tanks and spigots and all that. Careful TIG welding, pressure-tested, and it's holding up fine so far (not for my truck - for my V8 Chevy Sprint). If you can find the leak, and know someone with TIG, you could probably repair the rad. The cheap rad will at least get you going. |
Re: Restoring Rusty
I had the same dilemma when I did my motor swap. I took my old harrison radiator to a couple of shops to have it re cored 450$ no thank you... I bought a cheapo aluminum one off summit and it has been fine no leaks and holds up in 110+ heat out here.

Re: Restoring Rusty
I will have to give some specs when I get back home. I know it is a 4 core has plastic end tanks.

Re: Restoring Rusty - Radiator Pressure Test

I did pressure test the bad aluminum one first before yanking it out, and I could not pump it up beyond 10 PSI (I was shootin' for 15 PSI as that's what the caps be rated at) anyway as soon as I would stop pumpin' the needle would head south, so in other words it would not hold pressure worth beans

and the mandatory Stare & Compare
1. Original (lasted over 40 years, we think) I liked this one because it came without automatic transmission nipples ~ Smooth! 2. Aluminum $275 (lasted a year) I had to make sure they shipped me one without the automatic transmission nipples - Sa Mooth! 3. Cheap $114 (what do you expect, came with the ugly automatic transmission nipples, lol) |

just wanted to share some valuable follow up on the radiator leak issue with you all, so the next day after installing the new plastic radiator and driving it around for a bit I go to do a pressure test, and as soon as I reach 10 PSI I hear a hissing sound and see a tiny drizzle from the upper radiator hose at the filler on the radiator (driver side), ok, time to tighten my fancy shmancy T-bolt style clamp, I didn't Gorilla it originally as the rad has a plastic filler tube, didn't wanna crack it, so now I tighten it a bit more and repeat the pressure test, and it still leaks - gosh darn it I think, here we go again where I fall for the Form Over Function look, and it bites me as always
So I replace the fancy T-bolt style clamp with the cheap Hand Slicer type, and tighten it just a tiny bit snug, and start the pressure test again, 5 PSI... good, 10 PSI... good, and then all of a sudden I hear another hiss and hear coolant hitting the ground, what in the world is going on? Well now the bottom fancy T-bolt on the passenger side Outlet is leaking, so I try and tighten that one a bit more snug, and repeat the test, and as soon as I get past 10 PSI it hisses back at me still and drizzles out some more fluid on the ground Man, I go into my cheap Hand Slicer Hose Clamp (HSHC) stash and pull out another ugly / sharp dime a dozen hose clamp and replace that shinny T-bolt one with it, snag it up just a bit and repeat the pressure test again, 5 PSI... good, 10 PSI... good, 15 PSI still good So there you have it gents, one defective T-bolt I can live with, but both doing the same thing and in the same spot of the T-bolt, right under where there actual bolt goes, tells me it's just a poor design or a defective batch of clamps thought it was worth sharing, I also strongly stress you all investing in a Radiator Pressure Test kit, cause you know finding those leaks without one would have been tough and perhaps dangerous, if you was to go looking around a steaming hot radiator with naturally built up pressure |
Re: Restoring Rusty
That’s crazy how they both were defective.

Re: Restoring Rusty
Soooo......was the reason for the leak in the full alloy one from those clamps?....or cracked tube/tank?

Re: Restoring Rusty
Breeze-Liner Breeze 9420 Aero-Seal Liner Clamps fit 13/16" to 1-3/4". They cost around $15 for 10. Never bought onesies.
I use Breeze clamps sized for 2" OD rad hoses down to around 5/8" OD heater hoses on farm and construction machinery. Unlike Ideal clamps the worm drive screw and slots can take proper torque without stripping the worm screw or tearing the worm housing off the clamp. The Breeze-liner clamps also have that thin liner tang that extends around the inside of the band past the worm slots to keep the hose from extruding through the clamp and loosening up. They aren't much more than the cheap Ideal stainless worm clamps. |

well no need to tell you, bubbles aint good, it leaks where the core meets the tank, but at least we did not buy a new(er) radiator for nothing FYI - non of my local radiator shops say they weld aluminum, so if you were going to make that recommendation I am a bit dissapointed to let you know that |

So it's been a year and just over 13,000 miles since Rusty became my daily driver. And over that time I put up with some noises and leaks, but it got me to work when I needed it. And allthough the car runs super strong and is tuned nearly to perfection, (second pic, lol) it's not all roses, champaign, and caviar.

For those of you who have cured your insomnia by reading or attempting to read this entire thread, you will recall that we did rebuild this engine about 18 months ago, but there was no professional machining done to it, it was all blood sweat and beers in my own garage.
Having said that, I have performed a couple oil changes on it over the last year, and whilst checking the oil level a couple weeks ago I noticed this. As my old co worker used to say, FEW PROBLEMS NOTHING MINOR!!! |
Re: Restoring Rusty
now before I get flooded with the blown Head Gasket comments, ha ha let me give you a bit of a background and bring you up to speed
I don't know when this problem started. I don't know if there was a problem before I rebuilt the engine. The short block is an original '74 engine, the top end now has '99 Suburban Vortec L31 cylinder heads. I did not drive the truck often enough when it was all original top and bottom end ie long block to tell you if my truck was running out of coolant then, I wish I knew. Well I've been adding water/coolant to it on a weekly basis seems like about a quart each Sunday night to last me through the week, but again I don't know if I would have had to do that before rebuilding the engine. Also, important to note that we can not tell where the coolant is going,
The truck runs strong and does NOT overheat, well not until it runs completely out of coolant. |
Re: Restoring Rusty - Engine Block Tester
4 Attachment(s)
since I could not tell where the coolant was going, I decided to give one of them Engine Block Testers a shot
You rent this kit from AutoZone or some other parts house, and you buy the fluid at NAPA, the fluid don't come with the kit The point of this test is to see if there are fumes in the coolant, this would would tell us if the coolant is making its way into the combustion chamber or exhaust chamber I think You remove the radiator cap and stick the tube in the radiator and run the engine while pumping the rubber thingie to bring some fumes inside the tube, the blue fluid will turn yellow if there are fumes in the coolant. |
Re: Restoring Rusty
Well the Plot Thickens as the results were negative. I watched some YouTube videos of guys using this tester and seen the fluid turn yellow, mine did not.
This is why I told you all to hold your horses before saying Blown Head Gasket as that would have turned the fluid yellow, most likely. And trust me I would love for this to be just a blown head gasket, but I doubt it is. |

I was off today so I decided to do a pressure test on my radiator / cooling system.
I pumped up the pressure to 15 PSI (standard radiator cap threshold I've been told) and went to the gym. Two hours later we recorded a 5 PSI drop, so no duh there is a coolant / pressure leak... but where the heck is it? For The Record: I did a pressure test like this once before with the valve covers off thinking I would see some bubbles in the valve train but no such luck. I may try it again but this time put the pump in where the water temp sending unit goes in one of the heads, maybe try both heads instead of pumping it up in the radiator, hey, I'm desperate to find this leak! |
Re: Restoring Rusty
Well poot. When all seems well. I had an engine that always seemed to sweat in the valve covers. I never really figured it out honestly. The oil itself wasn’t a milkshake and the water level was always the same. Ghost condensation I guess. Bad PVC or something. Good luck and hope you get rusty back together safely and running good.

Today when I Googled that part number I came across this article: Fel-Pro Introduces Solution to Intake Manifold Gasket Leaks on Millions of Vehicles. Publication: Business Wire Date: Thursday, October 14 2004 You are viewing page 1 SOUTHFIELD, Mich. -- Fel-Pro(R), the automotive service industry's premier brand of engine sealing technologies, has introduced an advanced PermaDryPlus(R) replacement intake manifold gasket design that solves chronic coolant leakage issues facing millions of light trucks and sport-utility vehicles. Fel-Pro Gaskets, "The Gaskets Professionals Trust," are manufactured and marketed by Federal-Mogul Corporation (OTCBB:FDMLQ). Available through Fel-Pro suppliers across North America, the brand's latest gasket innovation ensures a lasting seal on millions of domestic engines that rely on extended-life coolant and were factory-equipped with rigid nylon and molded rubber-type intake manifold gaskets. A broad range of domestic engines may be susceptible to these sealing issues. Immediate coverage of the new Fel-Pro solution is offered for General Motors 5.0L and 5.7L engines manufactured from 1996 through 2002. Additional coverage -- for select Ford (3.8L, 4.0L and 4.2L) and G.M. (3.1L, 3.4L and 4.3L) applications -- will be introduced in early 2005. "It appears that on some engines, the use of conventional plastic-and-rubber gaskets in combination with the more aggressive 'OAT' (Organic Acid Technology) engine coolants has caused a significant number of sealing-related issues for consumers and automotive service providers," said Fel-Pro Chief Engineer Jerry Rosenquist. "Our team has spent the past two years developing and testing a variety of gasket technologies that can survive in this very difficult operating environment. (Dex Cool for those forum members who might not know) "Our new PermaDryPlus gasket is absolutely the best answer for millions of engines exhibiting sealing problems induced by aggressive coolant chemistries and engine-specific dynamic issues." The new Fel-Pro PermaDryPlus gasket features a high-strength aluminized steel carrier that is edge molded and encapsulated with a proprietary fluoroelastomer (FKM) material. In addition, the new gasket features three separate sealing beads around coolant ports to ensure a long-lasting seal under any situation. A key element of the Fel-Pro design, the new FKM material was specifically formulated by Federal-Mogul chemists to resist OAT coolants. "We ran our final dyno test for 612 hours and the gasket looked so good it was difficult to distinguish it from an untested part," Rosenquist said. "The steel provides the strength needed to resist cracking and crushing, and the FKM provides exceptional fluid sealing under all conditions. This design solves the primary leakage issue everyone knows about as well as other concerns typical of engines that have entered the repair cycle. "The consumer and service provider recognize the problem by the coolant spots that are left on the ground. Unfortunately, retorquing the manifold bolts simply causes additional damage to the carrier, making the leakage much worse," Rosenquist added. Coolant ultimately can leak into the engine oil, causing significant damage to internal components, he said. Fel-Pro engineers tested several gasket technologies before identifying the new encapsulated design as the best solution, according to Rosenquist. "Our ultimate design is the right choice by any measure - strength, fluid sealability, corrosion resistance, affordability, and ease of installation." |

I have no idea how this large counter top gets filled up with junk faster than I can blink an eye, the fact that it's empty is such an anomaly this may be the first big truck project in the new house, "our" new house, since we finally bought a place last year and will not be moving this year, ha ha |

now I learned this the hard way, so one of the things I like to do before yankin' the distributor now is to line up the Top Dead Center TDC mark at 0 and take a note of where the Rotor points to
(I find that removing the spark plugs makes it a whole lot easier to turn the engine over by hand - plus it don't hurt to read your spark plugs from time to time non either) Now I'm too tired right now to explain why it don't be pointin' at the #1 spark plug I recon it's pointin' to where it's pointin' (more like at #2) on the account of my 15* or so degrees of initial advance or something like that either way note where it points to and with this extra step of lining up the TDC mark I know that when or if things shift during this project I can get it all lined up again headache free |
