valve cover gasket questions (with pics!)
hey all
95 gt
1.6 roller rockers
stock valve covers
previously was an e-cam when the old gaskets were put on, now is a comp cam with if i recall correctly is practically same lift. i dont know if the cam matters for my issues, but i figured i would add the info here. covers havent been on since cam was installed (part of putting back together)
in process of putting engine back together after having it apart for quite a while.
i saved at least one of the gaskets (pics below), of which im not 100% sure which side it was on, but i am pretty sure it was the passenger side.
so, the gasket was doubled, and i assume it was doubled to clear the rockers.
i dont want to put everything back together and find out theres not enough clearance. so, could i just be safe than sorry and double up both sides?
i can put a single on each side and turn the crank by hand and listen for tapping, but i dont know if that is just as good as running the engine. or perhaps running the engine with not enough clearance would be very very bad?
anybody running 1.6 rockers and stock covers and had a clearance problem?
i know the end rockers were shaved to clear the sides of the covers.
also, in one of the pics, you can see some metal disks around the bolt hole. all the bolt holes have these metal disks and on both gaskets. i suspect these are to prevent you from compressing the gasket(s) too much?
in the pic of the doubled gaskets, the outer edge looks quite tall, but the compressed area is much thinner, you can see this in the second pic.
thanks for any input!

if it has roller rockers, and you wish to use stock covers, double up on both sides, use a can of "the right stuff" and glue them together with it, lay a set of books on top while drying, I have done it more than once for customers

One way to do this is to install valve cover spacers.
The metal things in the gasket help prevent the valve cover bolts from coming loose.
Gaskets with a metal core do this also but I would not stack those.
You can set the valve cover in place without a gasket and just 2 bolts partially installed then have someone turn the engine over and if the rockers hit you will feel it. If they do hit and actually lift the valve cover at all then one gasket will most likely not be enough. you should also be able to see the cover lift slightly if there is much interference.
Aluminum spacers around $100.00

Yikes.thanks guys.I pot the covers I with the gaskets and hand crammed it all the way around twice and didn't notice any moisture that sounded like a rocker hitting the cover. I'm guessing with the engine running they might come up a little higher though?
Typically I would wait to hear responses from you guys, but this time I thought it was safe to move along.damn. I gotta undo this all now?

dont risk hitting! guy did that for a reason... the metal disks are for compression, nicer gaskets have them in a circle around where the bolt goes to avoid compressing it. I would
do what above member mentioned but be sure to use some sort of adhesive gasket maker to put them together just a few dabs. or Buy some cheap valve cover gaskets or some cheap ebay "machined" tall valve covers ive always had great luck with those!

don't waste your money on spacers, totally unecessary for the little amount of clearance needed, double up on the gasket as I stated.......with spacers you run the risk of raising the valve cover to interfere with intake then you could need a spacer for that = chain reaction
thanks all
