cylinder sleeves

Post by CalJim »

Does anyone know how well the 2000 engines take having a cylinder bored out and a dry sleeve inserted? The cylinder would probably need to be bored out 6mm or so for a press in sleeve and I'm wondering if there would be enough mettle left in the jacket. I am presented with this option do to a honing machine accident which scared one cylinder badly. The other option is to bore out all of the cylinders to the next oversize (+.8 mm).

if you're going to bore it 8mm, why would 6mm for a sleeve be a problem? Sleeving would prevent you from buying a new set of pistons

Can that engine be safely bored 8.0 mm?
The oversize that I was thinking about is +0.8mm not 8.0mm. I should have included the zero before the decimal point. Sorry that it wasn't clear.
I think that I will go with the sleeve. The pistons were a special order.

Hey Jim,
IF you are going to do this, keep us posted on the progress and some pics along the way. I am sure this would be of interest to several members.
Thanks

what pistons did you special order? I,m looking at wiseco, they have a lot of options and I want to hand profile the dome.

First, I'm sorry that I have taken so long to get back, there have been many distractions. The reason that the pistons were special order is that they are 0.4 mm oversize and standard compression. Higher compression oversize pistons seem to be readily available. I live in the greater Los Angeles area where 1980 automobiles are still inspected for working original equipment and tested for exhaust emission. I was concerned that higher compression pistons could increase the NOâ‚“ emissions beyond the allowed limit.

I decided to go with the sleeve. (The parts supplier didn't want to take the pistons back). The machinist claims to sleeve most of the push rod V8s that come through his shop and I did find some companies that manufacture the 84mm sleeve for the 2L FIAT. (All in India). I still do not have my engine back from the machine shop so it will be late in the summer or even the fall before I'm on the road again with my 2000.

If it is of any interest I have taken photos of the disassembly and I will take more of the reassembly as well.
Thanks for the comments.

I finally got the engine block back in September of 2008 and I took some pix of the block and the cylinder with the sleeve in it.

Unfortunately I forgot to take photos of the reassembly process. I was glad that I took photos of the disassembly as the photos in the shop manual are not as detailed as needed. After putting the engine back in the car (In February of 2009) and replacing the fuel in the system it fired right up and I ran the engine for about 30 minutes at 1500 RPM to seat the rings. Everything sounds good. Only time will tell if the sleeve will be OK. I'll post again if it turns out to be a problem.

thanks for the update, I'm sure the sleeve will be fine if a competent machine shop did the installation
