Hi,
a few minutes ago as i was driving, the engine started making a tac tac tac noise that follows the rpm - it sounds like an old vw beetle.
No oil pressure issue nor heating nor change in power.
What can it be ? Is it safe to drive further?
Thanks,
pierre

Sounds like a collapsed lifter from your description. Open the engine compartment and use a long screw driver as a stethoscope to find the origin... if you get more pronounced sound from one of the valve covers or heads, that's probably your culprit. I changed them all last year at about 60K miles because one collapsed. Probably good to fix it before driving much... you don't want the lifter to impact the valve stem too much and deform it.

That's usually an early sign of a failing lifter.
As the engine rpm goes up there are more oil pressure so more oil is getting pumped to the litters keeping it from collapsing.
