then it was time for the Main Event
here's how to paint an engine block the hard way, LOL I swear I spent more time masking this thing than actually shootin it, when its all masked you realize there aint that much to paint after all used high temp primer on this bad boy first, then the paint went on that last pic of the can of primer refuses to get posted vertically, sorry fellas |
Re: Restoring Rusty

so first the primer, this is the primer for things like the headers, the guy at O'Reillys ordered the wrong one from another store for me, the one I wanted is for painting engines, but oh well this one withstands more heat, if it was the other way around I would not have used the engine primer on the headers, confused yet, good

and here it is the finished product, after two light coats and one medium coat as per the instructions
it has been a long time coming fellas, but I love how it turned out, I know it looks like bare metal, but I like that look, no orange, or blue engines for The Greg that's for sure |

well while we are still beating the break-in oil horse to death, I wanted to share that Summit still sells what I was hoping to find at the local parts houses, an old school 30 weight break-in motor oil, now I aint gonna order my oil, I am just gonna git some cheap 10W-30 and dump some Zinc additive to it, and call it good, it aint needed for more than about a 100 miles anyway
|
Re: Restoring Rusty
100 miles?! The break oil is only required for the first 25 minute run @ 2,000rpm. Once you have done that you drop the oil and replace it with fresh oil.
Once you have fresh oil then you drive the truck like you stole it for 500 miles then drop the oil again and put fresh oil in and then stick to regular intervals. You need to change the oil immediately after the break in to remove all the small pieces of metal that may come off from all the new parts or you can risk damage internally. |

Re: Restoring Rusty
I'm curious since he didn't replace the bearings will he have as much metal flake in his oil from just the cam swap. I have no idea I'm just curious. Whenever we broke in a new cam we used cheap oil with GM additive(straight six for racing) and run it at 2500rpm for twenty minutes or so. Changed the oil. Went to VR oil and Lucas oil additive and never seemed to have a problem. Though this was on a racing engine.

Re: Restoring Rusty
flakes will come from lots of areas... cam, timing chain, lifters, push rods etc.

so I stopped by Pep Boys on the way home from work today and decided to pick up two of these valve cover breathers, I have some but they are chrome and I prefer the black ones, I was so tickled as they rode shot gun with me on the way home
|
Re: Restoring Rusty
5 Attachment(s)
when I got home I was quickly reminded why I didn't buy the black ones in the first place, they don't fit in my valve covers, they is too big!
so on to Plan B, here's how you paint over Chrome, you don't you wire wheel it off, I tell you I never thought I would be thankful for poor chrome plating, but I was, and soon we were down to the nickel |

a quick spritz of primer and tomorrow we'll be ready to make them black
What do you mean you never night painted? It's great, everything you shoot, turns out great, well until daylight, ha ha |

but that's not what today was about, today we took our first step on the journey to reassembly, we put together the driver side Vortec cylinder head (C 16 9)
we set up our little station for production line like cleaning of parts and assembly, and miticulously cleaned every part Fun Level = 5 |

my buddy Pontiac Mike loaned me these valve stem sleeves to protect the rubber seals while I slide them on, but these sleeves proved to be a bigger pain in the butt to remove (with oily paws) after the seals were installed than installing the seals without em, LOL
I just used a deep socket to press the seals into place |
Re: Restoring Rusty

I only used oil on the valve stem so it would slide into the guide easier, and a dab of oil on the retainers so they would stick to the shaft while I released the spring, there was no assembly lube used at this stage
first valve done second valve done and all 8 done in the first cylinder head time for supper |
Re: Restoring Rusty
make sure to put a small dab of Assembly lube on the tops of the valves for the rockers before you cinch that all up and make sure to use assembly lube on the bottoms of the lifters too.

Re: Restoring Rusty
Nice Greg that is for sure a tedious job and I agree it is about a fun level 5
|
Re: Restoring Rusty
Looks good ,and our good Pep Boys store one county below us closed and a new one opened nearby here that only does oil changes ,that sucks as they used to carry things our regular parts stores dont .
Keep at it and we will keep watching . |
Re: Restoring Rusty
Take your oil can and hit the inside of that guide with oil. Then take your hand and cup it and put oil in it, use that to oil the stem of the valve. Put the valve in and spin it as it goes in. I can not stress how important this is. The valves see most of the heat and will stick very easy. Trust me on this Greg they need to well lubricated and the start of the engine.

interesting, the thing is won't all that oil just run down in the time it takes me to clean up and paint the frame rails and motor mounts etc. I am thinking a month of sitting on the engine stand looking pretty when its time to break her in, we plan on filling the engine with break-in oil from both valve covers, essentially take the covers off and poor the oil all over the valve train and watch it drizzle down in each glorious Vortec head, then we'll do the electric drill on the oil pump shaft trick while rotating the pistons 1/4 turn a couple times around as all the valves open and close, than a quick prayer and BAZINGA! |

The oil film on the valve stems should hang around for quite a while. If you're worried flip the head on its' top and squirt some motor oil on the stem where it comes out of the guide in the ports the night before you bolt em on. |
Re: Restoring Rusty
ASSEMBLY LUBE EVERYWHERE!
And then when your done.. prime that engine! Your not hurting a thing. Better to over lube than under lube. |
Re: Restoring Rusty
GREAT NEWS: I was able to return the bad/extra heads for a full refund!
So I am only out like $75 bucks for a set of [ahem] slightly used GM Vortec heads with rockers. Score! |
Re: Restoring Rusty
Great news ,now you can spend that on something else .

more importantly assembled the second Vortec cylinder head, the passenger side - I think these heads turned out great

did some mundane cleaning, like this gross fule pump plate, and learned my fuel pump actually does need two gaskets, there's the 2 bolt hole fuel pump to spacer/plate and another four bolt hole one between this plate and the block, who knew
I'm showing you this kinda stuff, cause it's not all Groupies and Booze |

spent about 45 minutes per side chasing the threads in the 17 head bolts per side
since I didn't trust my cheapie tap or chaser what ever it is called, heck there may be even a difference, I just decided to clean an old bolt or two very well with a wire wheel and using mineral spirits so that I wouldn't go in dry I cleaned up all the holes until I could screw in a bolt by hand and unscrew it by hand clean threads are important because these bad boys will be torques down to spec and we don't want the heads a warpin' Fun level - 5.8 |

I leave you with a question, if I don't plan on using my heater core, do I need to loop the intake manifold to dump directly into the water pump using that short hose about 6 inches or so, or can I just plug that opening in the intake manifold, especially since the matching hole is already plugged in the new water pump,
port in question shown with the screwdriver below |
Re: Restoring Rusty
Plug it
