hi all...new here
ive v40 2litre turbo 1998
engine problem.......

engine missfiring on pistons 1 and 2
changed the independant coils, sparkplugs
but i still have the same problem

its driving me mad

if its valves anyone got idea of place to get them
thanx for listerning

 

Have you done A compression test and cylinder leak down test yet?

 

just done one...no compression on 1 or 2

 

Now you need to find out if it is the valves or the rings.
I think it is pretty safe to say now that you need to remove the head and check it out.
