Have recently had a 1.4 8v HDI in the workshop, vehicle is not jumping! Error memory read out, Syncronization camshaft / crankshaft coharence. So control times checked, control times offset by 3 teeth da tension roller defective / loose! Tilt levers tested were in order so control times corrected and tension roller and timing belts ern, motor turned out in order! Engine so started, engine still does not jump on. Error memory read out, no errors! Parameters Injection tested Syncronization KW / NW available, Rail pressure io, air quantity io, EGR io, exhaust pressure io, compression varies by about 4 bar per zyl! After 2 days I have found that the cams on the cams shaft have been twisted minimally, that means the cams are twisting rather than the tilt levers break, since the cams are only shrunk up! Madness !!! Well, if you know no problem! That’s why this contribution from me!
