Thread: Head Gasket and Gasket Goo?

Aha
have finally found the culprit, Mr Incisor it was you that must have mentioned it in a post some time ago, almost similar times frame ( 15 years) and a series repair that is still untouched from when you first bogged it up. Many thanks i should have asked you in the first place.

Now i remember the correct name Stag Jointing Past, not gasket goo.See what the modern times have done to us made us forget the simple things we used to use.
Anyway its too late now, i bought a tin of hylomar yesterday, quite reasonably priced too from supercheeeeep. and the instructions are easy to follow.

I also did a hylomar web search, seeing what the stuff was developed for and its applications, it is the stuff to use. Nearly all the private stuff i looked at recommended it.

I guess the reason people say it is no good is because they put a glycol based coolants in straight after using it on the gasket.
After all that is what instructions are for.

Also watch for binding threads that may result in uneven tension.

One tends to forget that there are home mechanics and self-taught persons doing these jobs, who are not familiar with the normal practices of the fitter's trade. Always pull the studs from the block, kiss the top of the stud holes with a countersink just enough to remove any hilling on the mating surface, always run a tap or die or die nut over the stud threads and the threaded holes. CLEAN AWAY ANY SWARF! Check your workshop manual for instructions as to whether the assembling should be done clean and dry, with anti-seize, or with a thread sealant.
