my buddy just called and asked if i would help change the oil pump in his 94 K1500 next weekend, as it is going bad. can it be done without pulling the engine? how big of a job are we looking at?

94 K1500 Oil Pump

it can be done with out taking the engine out but you might have to remove some of the front axle. What is the reason for changing the pump?

oil pressure is going REAL low at idle (below the reading of the guage in the dash), my buddy disconnected the sender, and tested it with a mechanical guage. the mech guage reads the same as the elect. guage. so he's got a problem somewhere, and seems to think that that is it. hopefully he's right.

what type of oil areyou running?
Get rid of the engine cooler because it sounds like it is getting ready to take the crank. The oil cooler starves the main bearings and rods of oil for about 5 seconds because it drains out over night. Probaly what he is hearing is the mains and rods knocking in the morning when he starts his truck. If it where me ditch the oil cooler that is my opinion. You will need to get a $30 adapter from GM because of the 4wd. Oil pressure is low because there is excessive wear in the bearings.

unknown what kind of oil he's running, but i'm going to assume its good, since i worked with him @ Jiffy Lube for almost 4 years, and he was completely anal about oil changes then.
as for the oil cooler starving the engine, there isnt a problem with any noise, just when there is no load on the engine. it hasnt made it to the noise stage yet, so we're going to replace teh pump and call it good. he pulls a trailer with it, so ditching the oil cooler isnt a good idea, if it even has one.
