now lets add some rubber to this metal sandwich, I give you the Greg-Pro custom gasket
we start off by making rubber and wood shavings this time |

and here is one metal plate and rubber gasket done, that's as far as I got tonight, tomorrow I hope to make the opposite plate and block off the water cross over ports on the intake manifold side
the plan is to put some fitting in the water temp sending unit hole and pump it up with air through that, stay tuned |

and so we pressed on and worked on the intake manifold side block off plates
still don't know how to transfer holes to plates so I just use cardboard, I'm sure there is some pokey thing you screw in the threads and tap with a hammer to leave an indentation I imagine, maybe some fabricators/machinists can advise |

I made the rubber pieces next for the intake block off plates

and so I made the matching other side, I labeled them L and R just in case there was the highly unlikely chance that my custom CNC machine was a gnats hair off and they end up side spcific - hee hee

then it was time to rip one of them long pieces for the other long 20" bracket
needless to say that consumed an entire 4" cut off wheel |
Re: Restoring Rusty
Gregski....digging your progress and long hours......in one of you photos I spotted your (what appears to be) OEM AM/FM radidio and said to myself....."self, ya won't know 'til you ask". Here it is, wood you wanna sell it? I'd love to have it for my 77 shorty.....thanks and keep up the great work. Its a fun read.

and that's the bottom plate or the skinny plate or the outside of the head plate what ever we want to call it

so that leaves us with the pesky little side holes

we need narrow metal strips to weld in here to keep these at bay
we even bevel the edges to give the weld bead a valley or a groove to fill |

I'm sure you've all heard of gassless welding called Flux Core, well this ain't it, this is when the Knucklehead forgot to turn on the gas on his beloved MIG machine, ha ha

Re: Restoring Rusty
Just throwing this out there but, could the 1.5 quarts you added be because some air worked it's way through the system and finally made it to the radiator? Then the 1/2 quart you added was just from the difference between a hot engine vs cold?
When you remove the heads this most recent time did you see any cylinder that was clean from ingesting water/coolant? Did the engine over heat at all in those 200 miles? What was the operating temp? I'm starting to wonder if you just like torturing yourself. |

we had the gas on for the other side, nothing to write home about but these beads are much better, hey The Greg is learning ok - it takes practice you know

got lucky with a pipe threaded adapter and a 3/8th barb 90° fitting, this will serve as the air inlet
|
Re: Restoring Rusty
What pressure do you plan to pump them up to?
What do you plan to put under the plate to seal the head deck? |

I don't own an air compressor so a bicycle pump was the next best thing
pumped it up to 40 PSI |
Re: Restoring Rusty

radiator caps are rated around 15 PSI so at least that maybe more, what ever my system will hold without blowing the hose off, ha ha |
Re: Restoring Rusty
Mix a small bottle of soapy water use it on all connections and leak paths. Check the whole thing so that way if its leaking through a seal you can explain why the gauge going down.

then it was time to submerge the head in some water
I may do a hot water test as well by dumping in some boiling hot water, but if the heads leak in cold water then there will be no need to go to that extreme |
