Rings on #6

[Anonymous]

Heres the deal. Cylinder number 6 on my car has bad rings. Is it possible to unbolt the connecting rod cap from underneath thecar by removing the oil pan. Then taking off the head and removing the piston with out having to remove the entire engine from the car? The car has 50,000 miles so im not sure if It will have the taper problem for removing the piston. also If I remove the piston and replace the rings will this require me to buy new rod bearings? srry if im confusing. any help is apperciated. The engine is a 3.3l 200cid I6 with 50,000 miles :

Yes, that will pretty much work. But you'll likely find you can only buy a full set of rings for all bores.

Also you'll need a ridge cutter to get the piston out the top. And a ring compressor to reinstall. And a hone to make things nice in there.

A lot of stuff can be done in-car if the wear is light-medium. The minute bearings need machine work, or bores boring, you have to take it all out.

Plenty of shop rags wrapped around the crank will keep crud away. Work cleanly and at a leisurely pace; you should be fine.

Once you pull the head, might as well rering them all. While you're at it, lap the valves and install new stem seals.
Good time to put new con rod bearings in.

8) i agree with big red and addo, long as you are doing one you may as well do the others. usually if one ring set is gone the others are not far behind, and since the rings are being done the rod bearings should be replaced along with the rod bolts for reliability's sake. and since you are under the car check the mains for excess wear. the bad part is when you reinstall the oilpan you have to be carefull when reinstalling the oil seal otherwise you may end up with a leak where you need to remove the motor to replace it and make sure it is leak free.

Sounds like a plan to me fellas i just didnt want to have to pull the whole engine. I will use my schools hoist and tools to complete the job effectively. I was planning on changing the seals too. I wont need to get new rod bearings tho right?

8) whether or not you need new rod bearings depends on the condition of the current ones. as long as you have the engine apart unless they are in near perfect condition i would say replace them. they dont cost much for a set. also like i said you should replace the rod bolts as well. they have a nasty tendency to break and ruin your day, not to mention your motor, when they are overstressed. that happens when they have been retorqued. i have reused rod bolts and have ruined my day along with a good set of rods and pistons.
