Althought saying that, I know it has developed a very slight and i mean "slight" leak from my rocker cover, which was a new gasket when i painted it, I didn't mention that above as it is the very slightest of leaks!

I wont get a chance to get it in the air to have a proper look underneath before its on the ramp at the test station!

Ian, I think I will give that cataclean a try, ive been reading the reviews and it looks pretty good stuff tbh! Ive not read a single bad review, and even read a couple that failed emissions on the mot, then used the cataclean as instructed went back after 10-15 miles and about an hour and then passed!
