i have had the above problem for about 6 months now,i replaced the hydraulic lifters with euro car part ones,but the problem is still with me,it is deffo a top end ticking,i had the same on both my mk2's and new lifters cleared this(the were gen vag lifters),have i got a bad lifter,one thing i have noticed is,that it is not all the time sometimes when i start in the morning or after work it taps and the oil light takes 1 to 2 secs to go out and other times with no probs its out almost instantly,i dont drive very far to work(not enough to get the car hot).lifters or oil pump probs???
anyone got any answers.
thanks
