My 2.25 petrol has developed a ticking that I though was tappet noise. I checked the clearance with feeler gauges and one of them had very little clearance. Maybe a few thou, but not tightened right down. I thought maybe I had burned the valve because it was a bit tight, so I pulled the head, replaced all the valves, and ground them in properly, replaced the head gasket and got everything adjusted perfectly. The tappet noise has not changed. I am now wondering whet else it might be. It really sounds like tappet noise, and it sounds like just one loud one, not across the whole bunch. Could this be lifter noise? Any other suggestions? It developed fairly quickly over a period of a few weeks and has not gotten worse, but is pretty distinct.
The noise it not very noticeable when the engine first starts up, but once it's warm it makes the noise.
I'm running 10w40.
