Hey guys, I'm doing a timing belt and headgasket overhual because of a crank seal leak. I was planning on doing the oilpump aswell. My question is weather or not I have to pull the block to put a new oil pump on?
If you still have the balance shafts it will be hard to do it in place, as when you pull the oil pump the rear shaft comes out with it and you'll find the driver's side frame rail is in the way.
How many miles has the engine done? Is there a reason you need to replace the oil pump, such as low pressure etc? If the oil pump is working fine currently I would just leave it in place and replace the crank seal and call it a day. The oil pump is hardly a wear item like the water pump or timing belt etc. It should last the entire life of the engine.
It's an aftermarket high volume pump made by I think Toga or something like that. The motor has about 17k but the oil pump has seemed to always whine under acceleration since I've owned the car. About 10k miles. I just really would like to go with an oem for logevity.
It's not just optimism. I've done it. /ubbthreads/images/graemlins/rofl.gif
Back in '03. Balance shaft removal. I can't remember if it's needed or not but I pulled the whole front cover and oil pump off the engine. Hard to believe but I've still never had the shortblock out of my car. /ubbthreads/images/graemlins/jawdrop.gif
