I want to replace the rings. Must I pull the motor?
I will be pulling the head this week to find out why #2 & #3 have low compression (120 & 160 psi vs ~205 in #1 & #4). Since the head is off, I would like to go ahead &replace the piston rings. I have searched the forums and I have not been able to find anyone that has done this with the block in the car. Can anyone give me some advice on this? Knowing this info ahead of time will help me plan the best way to get my car back on the road soon.
Thanks for any help & guidance.

Hypotheically you could....... one you have the head off you could pull the oil pan off and be able to access the bolts for the rods but it will be quite a PITA. Also, you would/ will want to check your cylinders for out of round and also verify your ring gap on your new rings. It's do-able but if you're going to be on your back doing the work I wouldnt imagine it would be very much fun....

Thanks. I have a dial bore gauge so I can check the bores for wear. I had the head off a couple months ago & the cylinders did not show any signs of wear. I was quite amazed. So, I have a feeling that my pistons and cylinders are OK. I have a clean & organized shop and can take my time on this & do it right. So, if it's really needed, I can pull the motor but would like to avoid if this task is doable.
During a compression test, my pressures went up ~30psi in all cylinders when I added 10ccs of oil. This and some issues with my dip stick popping up tell me some new rings might do some good. Oh, my car is a MY 2000 with 84k miles.
The pan appears very easy to pull off as there is nothing blocking it. I am not sure about the oil pump though. I am on vacation now & don't have my manual handy.
Keep the suggestions coming please!!!

The oil pump WILL be in the way but it's pretty simple to pull off (3 bolts) There also isnt a gasket on it. It'll be quite messy on you with residual oil dripping but it is possible. I am actually currently putting my engine together right now. If you have any detailed questions just let me know.

Read this post, especially reply #35, before changing the rings.
Just new rings may not make things any better.

yeah our motors have special walls or w/e... when i had my motor rebuilt i had to drive down to Inline pro inorder to get it machined correctly. Theres only a few machine shops that can do what inline pro does.. from what they said its a special machine that does it
