Rebuilding the engine in my 94Z. It has 113k on the clock and still has the factory crosshatching clearly visible on the walls. I'm just going to have it cleaned up with a fresh hone, new cam bearings and freeze plugs at the machine shop. I'm just re-ringing it and putting in a new crank and bearings (because I got a crank cheaper than having mine turned) because of a rod knock. I have inspected all the lifters and they all look great. No marring on the rollers, lifter bodies or anything. All the rollers feel free and smooth as well. I have taken a pushrod and pushed on all the cups and they all feel the same: they have a little bit of give when you really push on them hard. They don't feel gritty or anything. Is there any other way I can have these tested, should I run them, or buy new ones (I hope to run these because money is getting tight after the machine shop bill). If I should run new ones then the car will just have to sit until after the tax refund comes in so I can get new lifters.

Thanks in advance.

 

I would use them and suggest not to hone the cylinders.

 

New rings will not seat without a hone. Or am I mistaken.

 

I reused mine without a problem. I just didn't wanna dish out anymore money than I already spent doing my head/cam swap. I'll swap them out when they go bad - which will probably be 100k from now.

If you're going to put in new rings, you might as well have the shop hone the block. It's cheap and will guarantee a good seal.

Just because he can see the cross hatch in the block doesn't mean he doesn't need a hone.

 

If you spon a bearing with those lifters make sure you go through them and clean them really good or you will probalby have a repeate of the rod knock.

 

Look up Careful with that hone Eugene.

 

Can you explain to me how a set of new rings will seat in if they cylinders are not honed? I work at a dealership and we hone every motor that gets re-ringed and have not had a single one of them comeback in the 8 years I have worked here.

 

Just buy new lifters they are only about 100.
With the old ones you run a higher risk of failure, they might last another 100k or 1k miles.

 

I can't expain it. You have to read the article. All I know is that I did not have any seating problems with new iron rings in that same situation. (over 100k on motor with no ring ridge, no out of round or taper, and crosshatching still visible. From my understanding the purpose of honing is to bring the cylinder up to final size after boring since boring is a rough cut.

 

The purpose of the hone is not just to bring it up to size. The angle of the crosshatch is important for the intended use of the engine. Also it is necessary for oil retention. I think I'll go with my experience and hone it. One of the lazy techs in my shop skimped out and just slapped rings in a car he bought cheap and sold. It still had visible crosshatch and it never quit smoking because the rings didn't seat properly.

 

Lifters aren't THAT expensive. Since you are rebuilding the bottom end anyway, why not just replace them.

 

Yeah....I just scored some extra cash so I ordered up a set of lifters here at work.
