Robert, The cylinder bores would need to be checked with an inside micrometer. Those measurements could then be compared with factory specifications. Example, not actual specs. if your bore is 3.000 inches, and it is measured at 3.002 you might be able to hone it, but if it measures 3.060, it would be recommended to bore it to 3.010 or 3.20 depending on the over bore pistons that are available. They also check for out of round of the cylinder, and taper of the cylinder, if any of those are out of specs, it would be recommended to bore it. If the cylinders are out of spec, you can put rings in, but it won't last as long, it is hard to venture a guess as to how long. Other things to check would be the crank journals, cam journals and lobes, cracks in the block, heads for cracks, and valve guides. My machine shop would boil the block, and check out the parts for $20-$30. Good luck and keep us posted. Michael

I am not looking for more power or milage. If I get either, all the better. I am simply thinking that with 150K on the engine If I plant it in something I don't want to have to deal with some of the commen high milage failures after going to all the work to up root and transplant it. Things like leaking main seals, head gasket failures, and all of the anoiing coolant leaks that I had to deal with on my S10 last year. And I figure with new rings and bearings if done wright the engine should last a long time. So there you have it in a nut shell. Now for determining if the engine is too warn to hone what is involved in that and if it is "too warn to hone" then what does a fello do. If I am going to be looking at boring and oversizing the pistons then I will scrap the engine because for me at this time it would not be worth the money . there are a ton of these little 4.3 engines out there. The trucks are rapidly rotting out from undernieth good engines all the time. Thanks for your feed back.

You will need to buy the timing set separately. I get my engine kits from www.northernautoparts.com As far as honing, you can do that at home with a drill and hone, but it is possible your engine is to far warn to be honed. It depends on what your goals are with this rebuild.

Well actually rebuilding might not be the proper term. If I do this at all, and I don't know if I willl, I again will be doing it for the simple reason of the sence of accomplishment. I won't do it until next summer. No heat in garage and not a lot of room. But I digress. What I am really looking to do is freshen it up. I have a list of things in my head for what I think needs to be done when going through an engine like this. What I am looking at goes some thbing like this The things I think I would need to replace are all of the gaskets Head, intake, oil pan, valve cover Inside I am looking at rings, connecting rod bearings, front and rear main seals, I think also as long as it is out and easy to get at I should replace the timeing chain or belt. I think this one has a chain but not sure. Question is, Can I get a one stop complete kit for this type of job? Also have I missed any major category? As I am thinking about it I know I have failed to mention a few small things like throttle body base gasket thermostat housing gasket and so on but I can check the list later. Now my other question is about prepping the cilenders. Can I do this at home with a drill and a honing stone like I used to do in small engine shop or do I need to drag it to a shop. I am not looking at boring it out or going with an oversized cam or any of that Like I said Just want to freshen it up. Let me know your thoughts. Robert Moore The sleep shade mechanic.
