ENGINE GURUS

[RT22]

Hey my 91 runs fine but after driving I notice at red lights and in driveway after a drive, top end is clicking, valve train, 190k just did timing chain so that is not it, is top end. It started after the timing chain, if timing is off can it cause this only after a drive and reving it a bit, short drives under 2k on tach seems okay but after a trip that takes me to 2500 rpm it now seems to tick on valve train. Or is it time to do valve train. I do not see how timing being off a hair would cause it but showed up after timing chain replacement.

Sounds like the all-too-common hydraulic rocker arms. Mine does the same thing. There is an article on NICO for cleaning the rocker arms.

Yup same here too. Mine sounds like it should be the t-chain but did mine also. When I got all of it off found my tchain and guides had plenty of life but eh, least its not a worry. Hopefully this summer I will get to trying a lifter cleaning and see what happens.
