i was out in the woods with a buddy romping a tractor and we came across this 4 cylinder G200 engine and manual tranny.

i got this crazy idea to rebuild the engine the best i can on a budget and put it into a go kart or tractor.

we had no idea how long the engine was sitting out in the woods. but we got a wagon, and ratchet strap, then towed the engine all the way back to my house and started tearing it down.

heres how it was sitting when we found it


redneck tranny removal, hahaa


ummmmm..... WHO COULD DO SUCH A THING


every piston siesed


cleaned it up with the shop vac.....


i got all the pistons out with a socket adapter and hammer




this is the block, and i know why it was in the woods in the first place.


one of the cylinders collapsed, there is a crack about 3 inches long. how do i replace this cylinder?

it aint pretty.... lots of rust... but that can be cleaned and i have belief that as long as i can get that cylinder replaced i could get it together and running, with a few more parts.

You're going to be lots of money and time ahead to start with a running engine

My brother said ''Everybody should rebuild an engine once.''

yeah, the time doesnt matter to me, just the money.

i do think if there was a way to replace that cylinder sleeve i could put it all back together. screw all the emissions control and guages and un-needed stuff. this is never going back on the road.

its one of those projects that i do when it comes to me, and its free to start with, otherwise i wouldnt even think about it.

im 15 and dont have a job, but i have lots of free time thats why i would spend a long time fixing the old parts instead of dropping money on new parts

in the past ive screwed around with small engines, (like lawnmower kind) then it turned into dirt bike engines and now its a car engine... helicopter is next

i agree with your brother haha

just an example of what i mean by "fix the old parts"

camshaft before:


camshaft after a little elbow grease.. a little more work and it can be useable (again this is not ever going to be road worthy)


EDIT: people have been telling me to scrap it, but i looked up the value and ill get somewhere around $11 for it. not even worth the gas to drive to the scrap yard which is pretty far away

Cool project. It's a way to kill time at least. Hope you can find what you're looking for.

you could have the one bad cylinder sleeved. would cost some money but if it is just being made to go romp around and it doesnt need to be perfect just save 3/4 of the oney and have the one cylinder sleeved buy yourself a cylinder hone and go to town on the other 3

thanks. itll be a long process

or just put the other 3 pistons in and forget about the 4th? haha KIDDING!

do you know about how much it costs to have a shop replace a sleeve?

i believe these are the kinds that have the coolant directly up against the bores. but i can be wrong

I admire your ambition!
This is something that you will remember doing 50 years from now.

take a look at your pics with the heads off. there is a gap of +1/4 inch or so.. a sleeve should be doable by an experienced shop. not sure how much it will cost you tho... i wonder how long it was sitting there to get that full of dirt

Around here to sleeve would be in the 25 dollar range plus you will need to bore the block and that will only work is the rust bores will clean up at .030 other wise you will need to sleeve all 4 holes. Oh and then you will be looking at cleaning the block decking the surface. The rods might need re sized the crank may be salvageable.

Cleaning up all the parts, boring, sleeving, etc is not the big issue. You"ve got to get the crankcase and all the oil passages COMPLETELY cleaned out. Use lots of fust remover and bottle brushes and a bunch of 12 hour days. One small piece of rust gets loose and it will most likely be bye bye engine.
The crank can be turned, the cam can be reground, and the rods can be cleaned up and resized, all would be like new.

I would bet if you check around you might find a used block, possibly short block that is in good shape for the same or less than what it's going to take to just do sleeve, bore and hone. No those cylinders are beyond honing, they may be beyond boring. (Pits)

The same goes for the head as to cleaning, checking for cracks and surfacing to hold head gasket.

A way to make money is to collect alum cans and other alum material.

sorry its been a while, i thought id tell you guys what ended up happening.

bought this truck for $1000, 1989 F-150 Custom, 300 i6, 5 speed manual, 4x4, long bed. all my money is really going into this truck now... (tires, lift, other stuff)



then i took the engine to the scrap yard with all the parts. had 700 pounds of metal and got $83.




i had to look at the engine as a whole, and almost NO parts were useable without replacing seals, welding patches, and the amount of new parts i would have to get is not worth it.

maybe in the future ill find a good/rebuildable engine to work with


the good thing is, i learned the engine inside and out while taking it apart. thanks for youre help!

Logic beats fun again.
