Hey! i have a friend with a 2.2 turbo that has some trouble.. we tested the=
 engine with a compression tester and found that he has only half the compr=
ession on cyll nr 4 then on the other 4 cyll's.

so to find out what was worng, either the pistons or the valves we poured s=
ome oil into the cyll and did the test again.. it was clamed that IF the pr=
easure increased with the oil inside it was the piston rings that were worn=
, and if the preasue did not increase it was the valves that was leaking..

the other cyll's had wbout 12 bar preasure in the test, cyll nr 4 has bout =
7 bar. when the oil was in cyll nr 4 we got more then 22 bar in that cyll..=
 the tester went all the way up.. you cant read of more then 22 bar.....

so i wonder it that maybe was a bit much?? or can it increase that much??

Regards Jan
