I have a 92 regal with the 3100 engine, 120,000 miles, regular oil
changes, clean yellow oil . Recently, upon starting the car , it had
excessive lifter noise..sounds like all of then are noisy......sounded
like a diesel,as if the lifters were not getting any oil.(it also now
runs lousy)The oil pressure checks at 60 psi at the sender switch near
the filter.........A local shop confirmed my suspicion and said an oil
passage to the lifters must be clogged. Has anyone ever heard of this
and is there any easy fix besides taking the top off the motor etc.?
How do you even clear out the passage? Can a pressure reading be taken
off the top of the engine?
Thanks very much in advance
