Replacing piston rings help...

So I've been back and forth with it, and finally just want this out of the way. I'm gonna just throw in some new piston rings, replace everything I need to, and get my car done to either keep it, or sell it for a reasonable price. What I need to know is, what all should be replaced while putting in piston rings? As in what should I do to help it out, and not skimp by? I don't plan on building it, just making it healthy again.

This is my list so far...

-Piston rings, of course
-Main bearings
-Rod bearings
-Headgasket ( I have an oem which can't be reused)

I'm not sure if I can or not, but I have a newer timing belt (less than 4k miles on it), but would it be bad to reuse this? And my once used arp's can be used again correct?

If there is anything else that should be replaced, chime in, thanks

The block must be honed for the new rings.

Re: Replacing piston rings help...

I would add an oil pan gasket to the list. If you are replacing the mains then the front case has to come off. Or at least I never took the crank out and was able to leave it on. So a front case gasket, and the rear and front main seals that go around the crank.

That's what else I would add if I was freshening up the bottom end.

* The belt can be used BUT things happen.

partsamerica.com has gator back ones cheap. They are good I have used them on all of mine.

No, you mean RTV (The right stuff rtv) to seal the pan. Gaskets should not be used.

Re: Replacing piston rings help...

Good on you if you can get your pan to seal with just RTV I never can..

But I do the gasket + RTV and not a drop comes out.

There is a gasket on the oil pick-up, but that can be made with gasket paper.

Re: Replacing piston rings help...

Cam seals for sure, they are a known leaker especially if you run synthetic oil. A valve cover gasket of course, the oil pump shaft seal, and you can reuse the timing belt if you mark the direction of rotation when you take it off and then install it in the same direction, the only aftermarket belt the I would ever use is a Gates, its actually stronger than a stock Mitsubishi belt, unless you run a kevlar belt. Why are you replacing the piston rings?

Re: Replacing piston rings help...

Compression is way down...90-100 across the board

Are you positive that it is not a head gasket or a valve sealing problem? Piston rings in these cars (stock) are pretty stout, I have a car with 300,000 on it that still has great compression, and another with 250,000 on it. They have had head/valve problems in the past, but not lower end related.

Re: Replacing piston rings help...

I'm pretty sure the headgasket is good, only has about 3k miles on it and arp's. But, on the valves...I'll have to look into that, what should I do to test everything out?

Re: Replacing piston rings help...

Do a leakdown compression test.

http://www.geocities.com/dsmgrrrl/FAQs/leakdown.htm

You can get a leak down compression tester at harbor freight and you may be able to borrow/rent one at Autozone.

Dont skimp on the bearings. I always liked King bearings for the mains/rods.

Re: Replacing piston rings help...

Personally, I would do a balance shaft eliminator kit.
Mitsu MLS headgasket
ARP headstuds
You can use oem studs on the bottom if you like.

Just pull out the block and have a machine shop do all the work. They could honestly do it in a day, but I'm sure it would at least a week with how busy they get.

Might as well throw some cams on that head if you don't have any.
