got my new motor today. picked up a 4.2L for my 87 yj today off a guy from craigslist for 150 dollars. gunna pop some new rings in it sometime this week and drop it in my jeep. post pictures of it once the rain stops and i get it out of my cherokee.
update, i went to discount auto parts today and ordered new rings, rod bearings, and a top end gasket set. 150 bones later it will all be here friday and ill start tearing the motor down. engine will be on the stand this afternoon and i will take pics
I dont have a ball hone but i have a buddy who does thats gunna let me borrow it. after looking at pics i think it is too. just wish i could find out which one it is so i could buy a rebuild kit for it. or do u think id be better off with the holley i have on my other motor?
thanks! i got it from the you might drive a yj thread! its definetly not a holley, if it is they made too completely different ones about that size, i have a holley here along with another crappy little carb. ive checked up and down this carb and cant seem to find anything stamped in it. got some free time tomorrow and gunna try and clean it up and see if i cant find something.
no i diddnt tear it down. i went and picked it up and the guy said it burns a little bit of oil so i figure id do this little bit of work to the motor and ill know what i have in it, its more of a temporary motor, gunna bore out and do a completely fresh overhaul on my other motor
update, tore the motor down today after work. pistons, connecting rods, crankshaft, and cylinder walls all look good. the bad, i have an exhaust valve stuck on my number 3 cylinder, whick bent one of my push rods. so options as of right now. valve job at the local machine shop and complete overhaul on the valvetrain including a new cam and lifters; buy a new head for 260, or do the 4.0 head swap. any ideas?
