Petroleum Jelly Versus Hylomar
#13
I have both. I hate the sticky mess that Hylomar leaves behind, but I also don't like the fact that Vaseline makes the outer coolant seal (black colored one) stretch. Since I always use new engine gaskets for all my rebuilds, and my engines last quite some time, I use the petroleum jelly. On the race engines I use the Hylomar. Sometimes race engines popped before you expect it and Coolant seals are still fresh and re-usable..Hylomar is a mess I hate it..

you've prolly tried this, but have you tried something else on the outer water seal? like a dab of silicon to hold it in place?

In the past I have always used Hylomar on the inners and an extremely thin coat of grey silicone on the outers. I have never had a problem with the outer seals doing it that way.
But, I think this time I am going to try the vaseline on both. Here's a question - when you use vaseline on the outer do you leave it off near the areas where you pick up with silicone beacaust there is no gasket?

True story I swear... One time I ran out of Vaseline and had some Vicks menthal rub laying around and I used the VICKS Menthol jelly. When the engine fired up, it smelled like the engine had a cold. Vicks smell everywhere when it melted..
