2G Buying a motor to rebuild need advice

[that2G98]

So guys I'm buying a spare 7 bolt for 350 today. I've never rebuilt a motor before but I wanna teach myself as I go with it and stuff so any advice, tips, and links will help thanks guys.

not a bad price, for the engine. but beware that it may be cheap for a reason. it could have issues with compression, bearings, and worst of all the dreaded crank walk. take your time and check measurements twice. use the manual when you can and purchase the right tools for the job. don't build the block for now either, build for later goals. I have some good parts for sale if you need anything , let me know.

Document, document, document. Take lots of pictures as you go so your remember how things go back together. Buy sharpies and a plastic zip lock bags, as you take things apart label them appropriately and bag them. Sometimes life happens and you can't work on your project for a month - are you really gonna remember what all those bolts on your workbench went to? Also, esp. when doing bottom end work - keep your work area CLEAN. You don't want to be working in a dirty grimy shop. All it takes a little bit of dirt or grit to ruin a bearing and trash your motor. Purchase or download a FSM so you have a guide to follow. Fortunately, there's lots of documentation on rebuilding 4G63's b/c it's a motor that's been around forever. Lastly, when your buying new rings, bearings, and timing components - buy quality (Mitsu OEM) stuff or you'll just be rebuilding it again.

I know that's pretty generic advice, but that should get you moving in the right direction.

FSM stands for Factory Service Manual.

Yeah shop charge is no joke. Spent 415 on just a bore, hone, and deck for my block. Def get the fsm, you can find free copies on the net.

If you look on eBay you can find FSM hard copies very cheap if you get the Talon ones. I paid like $10 shipped for mine. Only difference is no Spyder info.
Also utilize rock auto as much as you can. I think I paid about $30 for a victor reinz gasket set.

How did the engine come? Head still attached? Timing belt on it? I'd look first to see if the timing marks line up. If not (or even if they are), turn the crank by ratchet and make sure it doesn't cease anywhere. If the timing marks don't line up, or the belt is off the engine, I'd ask questions to the seller about that. Ask why it's like that and why it's being sold.
