Distorted cover? blocked crankcase breather? excessive piston wear? Incorrect fitting in the first place? Get a cylinder leakage test done , better
than a compression test .

Happened on my 2L silvertop on a 300 mile journey. Blew out the left hand semicircular bit at the back of the exhaust side of the cam cover. What a
mess.

Is the cover distorted? Are you using the cover oil breather as the one on the block is normally closed unless connected to the inlet manifold as it
requires negative presure to open.

I've found they need a smear of silicone (oil resistant type) round the corners and over the top of the cams at the pulley end. Done this on the
last two gaskets and I have no leaks.

I plan to blank mine off, but run a breather tube from it to a catch tank. I've heard they put out a lot of pressure there, so if you bottle it
up, I'm guessing it has to go somewhere.....

Hi you certinaly don't block off the breather on the side of the block. Either use the std smaller version breather pot or make a plate and a
pipe pointing generly up hill. Pipe bore of at least 5/8" 15mm and connect to a catch tank along with the one of the roker cover .
ps I have never found one off those nise little k+n or pipercross filters that works for that aplication .
cheers matt
edit to say sorry zetec 7 i didnt see your post it was off the bottom of my page.
