Default 302 problems

Well to start things off my dad's Bronco II has a fuel injected 302 in it.

Seemed to be burning oil more than gas

So this weekend we pulled the motor and yep I was right it's pretty well wore out.

We really don't have much up here for machine shops the closest thing we have is Napa Auto Parts. They claim for under $300 they will take the bare block, clean it and boar it. Anyone ever use them before?

Seems like a decent deal to me. Just would like some more input from others.

Thanks!

Does it need to be bored? If you get it bored, you need to buy new pistons and all related. See if its in good enough shape to get a good hone job and reuse what you have.

I don't know if I'd go that big on a 302. Not worth it for 4 or 5 cubic inches.

if it needs .04 over then theres no issue with that. the cylinder walls arent that thin on them but if it will clean up with .01 or .02 then i would just do that. minimal as possible incase something else happens down then road and you need it again. i can tell you that my buddy had a napa motor built one time and it wasnt very good. now that wasnt the one up there but still take what you want from it. typically you can get a bore and hone for about 200 and that should include a wash in there. figure on about another 50-100 to r and r cam bearings and oil and freeze plugs. if u were closer to me i would say bring it to my shop. but i would say its worth a hour drive in any direction to find a good machine shop not a parts store that just does machining work. just my 2 cents though

If you put the pistons at the bottom of the cylinder you can move them side to side quite a bit.... It's burning a lot a oil too

since its such a common engine, and good used replacements can be had pretty cheap, I would first look at the total cost to rebuild what you have, and then compare that to a good used or a reman short block...sometimes rebuilding is cheaper, sometimes its not...with the state of the economy right now, I wouldnt be surprised if you could find a whole vehicle with a good engine that you can drive before buying for less then the total cost of rebuild, and then get some back when you scrap the car

I was working at a dealership and someone had installed a new motor from napa, and it was burning a lot of oil. We pulled it apart and some dumass had put the wrong size pistons in the engine. it was off by at lease .010
Since it is obviously not a stock motor, put a mic in those cylinders and check for size / out of round, and then check the pistions. Hell the block might already be bored .030 over and not even worth the money to fix up.

just something to think about

Define "alot" of side to side. different pistons have different clearances depending on manufacturor and application. we've built motors that .002 clearance and some that have .008 clearance. i would have a shop or u if you have a bore mic check the bores first before you assume. you could just crosshatch the block and put new rings in and be good. also burning oil isnt neccesarily a bottom end issue. you could just new valve seals or intake gaskets. dont just assume the bottom end needs rebuilt though.

I wouldn't let a napa machine shop hone a briggs and stratton. The last engine I tore down that they "rebuilt" had 3 different sized rod bearings and 2 different sized main bearings in it. Poor quality work from them, at least in my experience with them.

I don't have a bore mic. But my roommate (mechanic) also agrees it's WAY to much slop the timing chain is also about ready to snap I'll make a call across the river ( canada ) I heard there is a good machine shop over there.

Thanks guys

sounds like your crank wore funny. prob could have line honed the block and turned the crank down to run the same stuff tho
