Those head gaskets with the red line are rubbish if you follow the enclosed instructions. They don't seem so bad if you use a sealer like Hylomar or high temp copper gasket sealer. I use the "BEST" branded graphite ones with sealer.

Yup, just like Synchro said, use the BEST brand gasket with the 5.5 head. They come in copper or graphite, 509C or G. Either should work very well.

A couple things I didn't see mentioned. The 1st one could be related to the lose head nuts that were mentioned but if the distributer was removed & the head nut that holds the clamp for the dist, cable left off for any length of time water can run into the oil. Don't ask me how I know this!! 2nd thing is I no longer use the so called "modern gaskets". These gaskets have a steel reinforcement ring around the cyl. & can rust. On one of my cars with a B motor which has steam vent holes that an A motor doesn't have one of these gasket rusted from a steam vent hole to the cyl. allowing water into the oil. I tapped those steam vent holes with a metric allen screw & installed a copper gasket & never had a problem since.

To answer asapguy question. The cooling system was completely drained as well as the oil before any disassembly took place. No water could have come from any loose nuts. We found the three nuts that surround the distributor not as tight/torqued as they should have been.
These are photos of the inside of the valve cover assembly, and for some strange reason a great deal of rust spray under the drivers side of the engine pan and side of the oil pan.
That area was clean and black when it left the shop several years back.

Default Re: Water in oil/engine-Anti freeze use is good

MY SEWAG on this!!

Looking at photo one.

1. I would look for freeze damage and cracks in the roof of valve chamber.

2. Also ALL of the water needs to be removed from main bearing feed tubes and camshaft bearing feed holes in floor of valve chamber!

Water in the oil feed tubes will prevent oil getting to bearings and will damage them.


3. Post 19 photo #2:

Reason number 657 for not using water and for using antifreeze. Looks like maybe the water leaked around the several studs and collected near the nuts at top of studs.

This water rusts the threads on top of studs.

Then when re torque is done the nut jams on the rusted stud and clamping force value is way short of what it should be. Result is leaking gasket.

If anti freeze had been used then if there are leaks it does not rust everything.

I’m with Benson. If it was mine I would tear it down and clean and lube it.
Also people in my club do not use silicone head gaskets.

All passages and rods have been cleaned. Pan and inner pan cleaned .

The customer that owns this truck does not want to spend any money. That is why it is in the shape it is. I would have preferred to remove the engine. But we've done this before. Well see how it comes out.
