I've seen EA82 threads regarding the Tick Of Death but I haven't found any specifically focused to the EA81.
I have a freshly built EA81 (with Hydro Lifters) with a rebuilt oil pump and a torque grind on the cam. I have what looks to be great oil pressure however I have a tick that always seems to be there though it changes intensity.
I was careful to check specs while of rods and bearings during the build and I have adjusted the valves and they seem to be well seated.
I'm just over 1,200 miles on the rebuild and did the final head re-torque fresh oil change with 10-30w this weekend.
I have seen quite a bit about replacing the oil pump gasket or doing a rebuild on the oil pump... my question is if the pressure is good, what does this accomplish?
Do I need to replace the lifters... would a torque grind cam require new lifters? If one or more lifters were bad wouldn't there be some play?
Sorry for all the questions but I would prefer to fix this right and have an understanding of the reasoning behind the repair instead of throwing heavy oil in (15-40 etc) and masking the problem.
Thanks again of time!
