Question:

How to change rod bearings on Pontiac Montana - Chevy Venture?

So, I guess I need to drop the subframe, crossmember and suspension.I can't get the oil pan out...If you know anything, help!

Answer:

It's gonna suck...big time. If it's knocking, you'll have to probably pull the crankshaft anyhow......
Make sure to take the side bolts out of the oil pan. Believe there 12 oil pan bolts 6 side bolts. You can do the rod bearings in the car meaning take the cap off(Do only 1 at a time mark an arrow pointing to the front of the engine if there are no marks on it) But only do one at a time. Rotate the crank so the rod is a straight shot to you, take cap off. Push rod up enough to remove install new bearing. Make sure to put bearings in one way, only fit one way. After installing bearing onto rod, make sure it is flush pull down on the rod itself to seat it in place. Do not use the rod cap the bolts to seat it first. Then once the rod looks like it is in position, then place cap on toque to specs. Then rotate crank if possible to go to next one. Do the next one in line, dont skip around or you may loose track BUT!!!! If you are doing this for the knocking noise at engine start-up, its the piston slap is what is causing that noise it is normal per GM
