8621, Valve cover leak. Posted by guest, Oct-11-01 07:35 AM
Well it looks like my valve cover gasket is leaking a little bit on the corner where the timing belt is. I guess I am going to have to change the gasket out. Can anyone give me some info on valve cover gaskets. Maybe someone who has had the same problem?

Easy fix... unbolt the valve cover(unhook the coil pack connector and anythign else in the way) take off the old gasket scape clean the head and valve cover matting surfaces. Put some RTV on the head, put the gasket down, ut some more RTV on top of the gasket. Put the valve cover down and tighten slightly. Let the car sit for 24 hours(idealy) then tighten down the valve cover bolt hand tight. You do NOT want to over tighten these.

I have oil coming out of my breather. My buddy who used to have the HRC Stage 2 had the same problem. He told me to just replace the breather valve because thats what he did. He said that after the replacement, it never leaked again. Has anyone else had this happen and replace the breather valve?

dont forget to replace the spark plug grommets too! AND, make sure your careful when putting valve cover back on...cause those grommets move just a lil' bit and u will have leaky leaky oil in your plugs!
The whole gasket set is $35-$40 at tha ####n dealersh#t, btw.

LAST EDITED ON 11-Oct-01 AT 04:16 PM (PST)Hey Michael, how come you do not want to overtighten the valve cover bolts? I just tightened them with a socket cus I thought I had a leak, but it ended up not being from the valve cover gasket...
OH and should I loosen them and then retighten by hand??

If you over tighten them they will snap off in the head, trust me. Just go until they stop and then a little bit more.

BUY A TORQUE WRENCH!
There is no reason not to torque down those bolts to their proper spec. It is just common sense.
And as for the leak....I have never seen a 420a that doesn't leak there. It isn't that bad, so its not really worth the hassle. If you really want to fix it, it will cost some $$ for the gasket set, but it isn't a hard job. Mine has been doing it since I bought the car in '99.

Sorry, I didn't actually mean to tighten with yoru fingers. I always use hand tight to mean not a lot of torque. on the wrench. Those bolts aren't that strong, like 420A said you can snap them off... believe me this SUCKS!!!!!! But it's more a matter of preserving the gasket. Not as much of a big deal with a good rubber gasket, but if you are working with a cork gasket, and over tighten... say bye bye and start over. But if you crush the gasket and split it, you will get a leak a lot sooner than you would have otherwise. I have a torque wrench and the torquw specs on the valve cover and oil pan have been too high and I over tightened going to the proper torque spec. Just feelit out. Tight enough but not too tight... (Sorry I know that sounds like a Grandma's descriptiuon of her secret recipe)

I don't have my shop manual in front of me, but it is in there in the engine section (duh:P)
Or check out Darkone's website for the downloadable version and check the specs there. Always torque down to the shop specs. That is what techs and mechanics do, and that is what you should do as well. Head over to Autozone or something and pick up a Chiltons if you have to. 16 bucks and well worth it.
