Btw, oil change just done a month ago.Have done 3000km since then.
Oil pressure gauge shows 2.5 after warmup and 3 during accelleration.
Current mileage is 298,000km.
Don't know if mine has hydraulic self-adjusting lifters coz it's a 1991 1.8.
If it is the lifters, would I hear it regardless whether in D while driving or revving in P?
When the tapping is heard, it is usually while I am driving. If I stop in N or P and rev, it is not heard.When I shift to D and drive again, the sound is there.Then it goes away as mysteriously as it came.
Used to think it only happens in the mornings.But looks like sometimes it comes even though the engine is warm.
However, for the past 2 days, I haven't heard it.
The lifters can be inspected by lifting off the valve cover, right?
