Default Tips on cleaning gaskets, surfaces, and reinstallation..

Hey guys, I've been searching around but I haven't found any direct DIY's or information about installing gaskets. Well, here's my situation, the previous owner of my car reused gaskets on the engine and theres a BUNCH of gasket sealer EVERYWHERE. Even inside the engine block a bit from where the TGV mount into the engine. How do I safely clean it, and reinstall new OEM gaskets?

When install new OEM gaskets would you recommend I use gasket maker? Or just clean the surface with a light grit sandpaper and just lay the gasket down?

And how would you recommend cleaning fuel injectors that have been collecting dust for awhile? I already plan on replacing the O-Rings but the fuel injectors in general are kinda dusty for sitting around..

I hate working on a motor that the previous builder was sealant happy, as long as your surfaces are clean and in good shape you don't need sealant, i have used gaskets over and over without sealant on my personal engines and never had a leak, MY PERSONAL ENGINES not customers. The valve cover gasket comes with a little sealant on it from factory that i usually duplicate.

No sand paper

I used my finger to pick at the overflow (It pulls right off) and for everything stuck on the metal I used those scotch brite pads by hand. Dont stick them on a drill or anything they are too rough. If it is on an area where its not very important to have a perfect surface like the top of the heads just use a razor blade at a 90* angle to scrape back and forth that works great for me : )

They also sell gasket remover in a can it works ok.


Good luck

Sweet thank you for the advice guys, this person wasn't sealent happy he went on a FRENZY!!! The water pump has a crapload of sealent, the up pipes, downpipes, valve gasket, you name it. I'm going apart one by one to tear down each part and cleaning off the gasket.

There's alittle gasket sealer inside the engine block, where the tgv valves meet the block where the valves are I believe, do I just spray gasket sealer remover and let it run down there? I don't know how I would prevent garbage from actually running down there.

When I was redoing my block, I used new gaskets. The owner before you should be thrown in jail for re-using gaskets because most of the gaskets are made of carbon or whatever and are one time use only. Once they come off the surface, you need new ones. I just used a razor and carefully took off the excess crap on the surface. If you are taking the stuff off and you happen to put a scratch in it or whatever, the new gasket should expand under heat and cover it up. Just be careful you are not gouging out the surface. I would replace all gaskets/seals that you are going through. You could take off the stuff where the TGVs are, but be careful. Try to get the solid bulk away from the combustion chamber. Some of the solid might be big and could clog up your intake valves which is not good. If you do use spray, don't worry about it. I used brake cleaner to clean out my intake manifold, and there was some left over when I dropped my engine in, and the excess was burned off in the combustion chamber causing white smoke out of the exhaust, but it was just what was left over, not a bad HG.

Great, I totally forgot about the combustion chamber, it would simply just burn everything out! Thanks guys, now I just need to locally source a place to get gaskets for cheap rather then go to the dealer and lose my arms.

I use strong solvents to clean, Normally brakeleen, and then finish off with a light polish with Scotch Bright.

I use scotch brite, however it will take a small amount of material with it. Another idea is an aluminum oxide or arkansas wet-stone... At least this way you may take some material off but you preserve the flatness. I recomend combining the scotch brite with PB blaster

PB Blaster, why didn't I think of that I have tons of that stuff.. what would you guys say about WD-40? Heard a lot of debates saying it's a good cleaner but attracts tons of dirt. My old automec teacher told me it shouldn't be used as a cleaner..

Scotch bright will take such a small amount off that you have nothing to worry about. Sand paper on the other hand is a big no no.

I personally use a stone to take off the high spots after i scrape gaskets off

I pull it off by hand and then use goof off on a rag for the rest. Razors are fine but anything else is usually too abrasive and aluminum is soft. The only gaskets really that I could ever think about needing any thing other than a gasket would be my uppipe to header since I use gruppe s which isnt the best fit and the valve covers. I use just the oem gaskets on tgvs and exhaust manifold to block.

Not to bump an old thread, but I used brake cleaner to tear off all the gasket cleaner. Worked wonders! For future reference just incase anyone has this question. Brake cleaner = miracle cleaner lol.
