2.4 connecting rod bearing replacement

[codell]

The oil pressure warning light came on in my daughter's 98 Sunfire when she was about 3 blocks from home. By the time she got in the driveway, there was a distinct rod knocking sound. So the engine ran on low or no pressure for about 3 minutes at very low speed. I've never had the lower end of a 2.4 apart before, so a couple of questions.

1. What are the chances I have damage on the crank journals? It's not a loud knock, but it is there.

2. How big a pain is it to drop the pan and balance shafts to get to the rod lower ends?

3. Any other advice?

Thanks much,.

1. Nobody can tell you that by guessing.
2. Looked at a Hanes manual for the Grand Am and there was no mention of having to do anything with the balance shafts for the oil pan itself but I would assume you will be replacing the oil pump also. Try getting a copy for your car or check your local library.

I have two manauls for my car, and I know the balance shafts will have to come off. A new oil pump is a given. What the manuals don't tell you is how much blood, sweat and tears you'll spend doing it. Was hoping to get that perspective from those who have actually done this work.

Thanks.
