Thread: Oil pressure issue

Tweet

There was a flap a while back about Fram filters causing problems, so I would change oil and use a premium NAPA filter (I think they're Wix). As far as the roller/flat tappet cam issue, for now I'd use an off-the-shelf oil and add a bottle of ZDDP to the oil. Roger's suggestion of using Brad Penn oil that has ZDDP in it will work also. If you find out in the future that the motor has roller cam and lifters, discontinue the use of the ZDDP and use plain old off-the-shelf oil.

If the swap was done with maintenance in mind (not likely), you may be able to pull the oil pan and change out the bearings. I never did like doing it that way, preferring to pull the motor and do it because if the bearings are gone, chances are the rings are toast also.

You can find out a little more about the motor by performing a compression test.....
Use a screw-in type gauge.
Bring the motor up to operating temperature and shut off.
Remove the air filter assembly.
Wire the primary throttle blades wide open.
Remove spark plugs.
Disable coil to prevent a fire.
Turn the motor over with the starter through at least 5 cycles on each cylinder to make sure you have maxed the gauge for that cylinder.
Post the results here.
