Questions: Trying to get oil pump off of cylinder block to replace - can this be done externally w/o getting into engine? (I have removed 3 bolts and faceplate on outside of engine - it is still stuck up aga engine really tight...) Thanks for help
Question By: Chris on Mar 8 2018 7:44 PM
It should slide down. Keep in mind the notch on the end of the oil pump goes into the tooth on the end of the distributor too. This can cause it to stick as well as the gear to gear contact on the camshaft.

Questions: can a worn oil pump cause sputter over 25 mph, Im getting my ass kicked, has rebuilt carb and starts great
Question By: Howard on Feb 6 2013 12:00 AM
I wouldnt think so, it really will just give poor oil pressure. But if you have chipped/broken teeth on it then it could be doing serious damaged to your camshaft and cause vibration or worse.

Questions: My MB starts up and oil psi quickly goes to 40 -- after driving a while the psi drops to about 12 - 15 psi and remains there unless the speed is increased; However, it does not reach 40 psi. Is this normal or is there cause for concern?
Question By: Anonymous on Dec 6 2012 12:00 AM
It shouldnt ever go over 40, the relief valve opens at 40. At idle minimum safe pressure is 6 psi at idle. At 2000 rpm (35 mph) it should be at least 20. So it sounds like you are ok.
