Were the valve giudes ever done on this engine,? With 156K more likely that is what you need..on 87 i have done several engine valve giudes at even 30k miles( 87 had problem with them)..i`m sure your is overdue.

October 2023 the valves were adjusted and new injectors installed. About 4K miles ago.
Valve guides have not been done. Valve guides seems to be where this is headed.
