engine gasket
« on: January 24, 2014, 01:01:27 PM »

 I am removing the leaking base gasket, 
any tips on how to scrape off the old gasket without  material getting into
the crankcase?

 I stuffed the holes with rags but I can see it would be very possible for crap to still get down below
and I don't want to crack the cases.    :-\

Soak them REALLY well with Permatex gasket remover first. Then, while you work, protect the cylinders and use a shop vac to catch the debris.

If you do get some falling in, drop the oil pan, and flush the engine with Diesel to aide in purging the debris.

I use an exacto knife with the scraper blade. It is very flexible so it gets under the gasket easy and doesn't really bite the surface.

It doesn't take as long as it would initially seem. It helps to get the material "wet" with some thinner or something

Diesel is a solvent and lubricant in one. You can buy it inexpensively and flush the case really well. Whatever residue remains won't damage the seals or bearings as some other solvents may. It's also a bit more viscous than standard solvents.
