You are watching: 1996 toyota corolla valve cover gasket replacement
I"m walk to go through how to change the valve covering gaskets top top a 1997 Toyota Corolla, 1.6L engine. Ns actually just needed to change the spark plug tube seals (grommets), but since I had actually to take it the valve covering off, it"s gasket had to be replaced as well (though I think there room gaskets that deserve to be reused in this application as long as they room not also worn).
First detach the vacuum lines and also move the cable harness over, and pull out the spark plug wire boots.
The valve covering is difficult to obtain off, because it"s to be glued on by year of heat and the gasket hardening and frying top top it and the engine. You need to be cautious taking that off, due to the fact that the cover is make of aluminum and it"s soft. You deserve to easily damage the valve covering or the engine v too solid of tools if you"re not careful.
I provided a hammer and a 2x4 because that leverage to pry off the valve cover, yet that"s more than likely not the finest idea, due to the fact that I walk gauge small marks into the valve cover. Mine dad called me it"s a much better idea to use a razor or a knife to ease the cover indigenous the engine, instead of trying come pry the off.
Be cautious so the small bolt seals native unscrewing the valve sheathe nuts don"t fall into the automobile or into the engine if you"re dismounting the valve cover!! ns took my valve covering off and while flipping it over 2 or 3 the these dropped into the engine! Luckily I can get castle out, but you don"t desire them fall in there and also messing up the engine. Be certain to eliminate them before you lift turn off the cover, due to the fact that they don"t come off through the nuts.
A flathead screwdriver deserve to be used to pry out the old spark plug grommets. It can also be inserted from the top of the valve cover, to hammer out the grommets. Just be mindful not to gauge the aluminum.

Step 2: Clean the Valve covering Gasket Groove, Spark Plug Seal seats & Engine
You must use brake cleaner to clean the valve sheathe gasket. Probably carburetor cleaner works too, I"m no sure. You desire to make sure to have actually the surface of the engine and also the valve sheathe clean before you put the old gasket on. The old RTV silicone sealant needs to be peeled away, maybe using a flathead screwdriver or knife, however carefully! A rag sprayed through brake cleaner works well come wipe off the engine surface where the gasket renders contact. Girlfriend don"t want to spray brake cleaner straight into the engine. Yet you deserve to spray brake cleaner onto the valve cover, just make sur to wipe off and pour the end the extra before reassembling the engine.
You can cover the engine v a towel throughout cleaning that the valve cover, therefore nothing drops in there!

The new gasket must be put onto the valve cover when it is clean and dry. The grommets deserve to be inserted into the insets top top the valve cover, ~ the old grommets have actually been pried out.
The brand-new grommets can be quickly pushed into the holes if they space wet v a small soapy water solution. This will certainly evaporate and won"t damages the engine, just don"t use as well much! simply a very tiny bit, and also you don"t need lot soap. The grommets have the right to be hammered in ar with a rubber mallet or a hammer and also towel. Be careful so you don"t hit one side also hard, and make it walk in crooked. They"re difficult to get out!! i tried to get one out after i did this, and I ripped it with a flathead screwdriver, and had to buy a brand-new $40 set!
