My gaskets are too big! I have a 280i fhc, and just finished a tappet adjustment, and went to fit my NEW gaskets from FAI, and they are too big, it is as if they have swelled up by 3% or so. Any ideas how I shrink them? Tried one in the oven on a low setting for 10 miniutes, and it came out bigger!

I don't know about the v6, but the castings for the "TVR" rocker covers on the my V8 are terrible, and I always need to trim the outer edges of the gaskets by a few mm at certain points to avoid them popping out from the joint that they are supposed to seal. As long as there is sufficient width to seal the joint you should be able to trim them - I assume they are cork or composite.

I glue them into the rocker covers with hardening gasket goo Don't forget to hold them in place with the mounting bolts/

Well,

I decided to try fixing one gasket into a rocker cover with RTV silicone and LOTS of clothes pegs ( and some bolts to keep the holes aligned) The gaskets bulge out if there is even a single peg gap, so I can only do them one at a time. Will investigate tomorrow.

Are you using the cork or rubber items?

Hi,

I'm using cork gaskets, and the one I stuck down with RTV seems to be holding without the pegs, but the surface of the stuck down gasket is quite bumpy.

Rubber gaskets seems like a good idea, but do they make them for the 2.8 Cologne engine ?

I'd stick with the cork gaskets if I were you. I used to glue them to the covers using red hermatite. It made my life a lot easier That is, until you need to remove them!
