Well since the new piston went in she's drove good timing was out a tooth fixed the timing again now runs fine however I moved house last week 20miles up the road nice steady 60mph on the bypass grave it a rev on the slip road and it was smoking carried on 2 miles to my house and all seemed good left it running I'm the street 2 days later and clouds of smoke when revved took it up the road a cleared a little


Compression checked


Cyl 123&4 all had 150 psi which I beleave is normal


Any ideas she's running 15w 40 mineral oil

Yeah, unless your running in the engine, drop the mineral oil out and put in fully synthetic

What's your oil breather set up?
Worst case - sounds like turbo, but check the other stuff first.

Catch can set up follow the braided lines

Was told on another fourm ditch the can and put a breather on the t piece and leave the sump line how it is

done the above took it a run stopped done a few hard revs and now she's running on 3 cylinders there's also oil coming out of port 3 of the exhaust I was advised to run 15w40 for the new piston :s is that not the case?


any ideas? Rings? Stem seals? 3&4 piston have oil on them looking through the plug hole shit oil?

Just done another compression check and all 4 cylinders are 11bar 160psi only thing I can think off is valve stem seals


Has any one ever replaced valve stem seals in place before if so how did you do it ??

Compression test was done with WOT
