Is it easy enough to change the cam cover gaskets yourself? I've just picked up some new ones with new bolts and washers as mine were leaking pretty bad.

Any tips and things to watch out for will be greatly appreciated :-)

basic job mate.

Just remove the nuts/bolts holding the two things down. Pull the cover off. Remove the old gasket.
I would suggest giving it a quick wipe down and clean up.

Carefully lay down the new gasket (should not have to use any additional GASKET GOO or anything) and simply refit mate.

Just make sure the gasket sits properly and does not get pulled off its position when you replace the cover.

but yeh, easy job .

Sounds good.

Anything else worth doing or checking while the cam cover is off? Do the bolts have a specific torque?

I put the gasket/seal into the groove on the cam covers and then put it on like that.

Give everything a good clean.

You can also change the PCV, or ventilation hose on the turbo side whilst you're at it. That little pipe that connects the two cam covers near the backend of the engine cracked when I took mine out but luckily I had an equivilent hose already.

Seeing you profession is chrome plater, why don't you do that too.

As for torqueing, I'd do it not very tight because they can crack very easily.

BTW make sure to reseal the half moon seals at the back of the head (held down with the cam covers) as well, clean the surfaces really good and a nice coating of silicone on both sides will do nicely :-)

Cheers fellas I'll give it a shot this weekend :-)

Matchy now I'm getting PM's asking me to chrome stuff. I'm a hardchrome plater which is the stuff on hydraulics. Hard chrome generally won't come out bling like decorative chrome does as the process is quite different.

I'd like to try it anyway though haha

Got the covers off it was easy as, man there's a lot of gunk stuck to the bottom of the covers! What's this about the silicone? Do I need it? :-(

I didnt use any silicone when i recently replaced mine . I just cleaned the surface on the head with some clean rags and cleaned the cam covers . I put the new gaskets inside the cam covers, placed them into place and tightened them down ;)

Nice and simple mate .

Done thanks guys! I gave the PCV valve a good clean with carby cleaner too. Cracked the hose going in between the cam covers and the one going to the inlet but taped them up until my new ones get here. Time for a catch can I think.

Oh, I applied a thin coat of fresh oil to the cam gaskets before installing is this okay?

Not really needed as you want it to seal, but should be fine mate .

the silicone i was refering to was to seal the halfmoons at the back of the head, mine were leaking down into my bellhousing profusely, not noticinble unless u put ya hand down theb ack of the head or remove the transmission haha. All they rely on is silicone to seal them as they are alloy instead of the usual rubber.

got pics? I have the gearbox out of the car at the moment trying to rectify some clutch slippage. I assumed it was a rear main seal leak, but inside is reasonably dry. There is some oil on the outside of the box though.

Scott I remember seeing the two half moon things now. What the hell are they for? So out of place haha. but yeah I didnt remove them as they weren't leaking but the bottoms of them were sealed against the head with some black goo stuff. This must be the silicone you were talking about right?

Ben what pics are ya after mate? I took a few.

You just gave me the 'word picture' I was chasing. My 'half moon' things have black goop as well. I wanted to see what they should look like.

yep, mine had the factory silicone still on them, but were still leaking badly.

BTW the reason they are there is to do with the manufacturing process.

They bore the camshaft journals, this is not possible to do without touching the outer edge of the head :-)

Yup, never seen an OHC head without them.
