Cam Cover Spark Plug Hole Inserts

[topcat1]

Hi all, have searched but maybe not well enough- my cam cover is being powder coated, and before I took it in I stripped it and the 6 "top hats" basically dropped out which push into the holes where the spark plugs go.

I'll be re-fitting this weekend and just checking do I just push the 6 inserts back in with a bit of silicone to seal them? (I should add they appeared to have been previously fitted with resin/araldite which had come loose over time)

I also have the posh gasket to fit when I put it back on, if it makes any difference.

Cheers,
TC

With the cam cover gasket you need apply some high temp contact adhesive to hold it in place, otherwise it can wander and lead to oil leaks.

These:



They came out of the holes in the cam cover.

Interesting. I'd probably just put a film of engineers adhesive/sealant on them and push them back in. Should be listed on tvr-parts.com

Be careful with silicon.........

Thanks, I was planning on using evo-stick to hold the gasket to the cam cover, it is common practise with Rover V8's so should be ok with the S6. Then I'm not sure whether to clean and dry the top of the head or lightly oil/grease it where the rubber gasket sits, may ask the shop!

Presumably it's the viton gasket from racing green/tvr car parts. In which case stick the gasket to the cam cover, and clean the head face.

If you check my profile I worked fairly closely with RG on my engine build.

It is indeed. I've tried to get bolts slightly longer but my stockist was out, will assess if I need to get longer ones when fitting it comes round!

I assume the top hat type inserts are so the HT lead seals tightly around the top. Picked up my covers yesterday- heres how they look! Look sooo good in the flesh, they will contrast perfectly with the gun metal grey car!



p.s. Matt I like your engine build thread
