Tapping after oil change
Posted: 23 Oct 2025, 07:34
I've recently bought a van i'm doing a mild resto on, she's been sat for 10 years
The engine however ran like a sewing machine.
I've just changed the oil, and it was very clean, but seemed quite thin to me as it came out
I put in Halfords 20w50 classic mineral oil and changed all the filters etc
Now when I start it I get a tapping noise, at a guess it's a hydraulic tappit that's not happy
Anyone had this? Did I go for the wrong oil? Or am I just hoping that the old oil was wrong and the valve clearances were set to that?
