need advice on a rebuild( 2.2)

[csomni]

ok, ive got about 5000 miles on a rebuild. lost my # 4 rod bearing. crank is getting turned again. and the rods resized. dont no why i lost the rod bearing. the ? i have is should i rehone and drop new rings in it. or should i put the old rings back in. i can still see the old hone marks in the cly. what do you think.

[raccoon]

id wonder more about the cause of the failure, but myself I would reuse em.

Make sure you clean the oil passages real good witth compressed air and pipe cleaners after you get the crank back from the machine shop.

i think it was a bad rod to begin with. didnt plastigauge it . and didnt have the rods resized, lesson well learned. this time going threw it with a fine tooth comb. dont mind tearing it down. but id like to at least get a couple years out of it lol

will do. you vwould think they clean them up after there done. but i guess not . going to go threw the oil passages in the block too

can a guy use break klean to flush out the oil ports.

While getting the rods redone, throw in some ARP's.b

Port the oil pump hole too.

Yes, brake cleaner and compressed air works great but usually what I do is use soap and water, and also similiar chemicals to Castrol Supercleans, clean and blow it out, finish off with Brake cleaner. Maybe its overkill but its damn clean. You can also have the machine shop hot tank it too.

I would reuse the rings, so if you do, skip the hot tank.

how do you like to drive? ive had to many problems taking turns to fast, and just a second of losing oil pressure would kill my bearings, i run baffled 2.5 deep pans now...

and if you decide on arp bolts (very good idea) then have the machinist torque, remove then re-torque like 5 times (or something like that) before he resizes the rods.

i really dont drive it that hard. every once in awhile ill put the pedle to the metal on the free way or a back country road. as far as the arps id let to put them in but i allready had the rods resized. or can i put them in after the resizing.

I reused my rings, had about 25-30k miles on them, didn't hone. Beat on it every day and doesn't smoke, I've put another 5-6k miles on them since the reassembly. I do get a bit of oil in the IC pipes though, however I am running a TBI cover which may not have enough baffling for a turbo car.

Incidently I had a rod bearing issue also, #3 IIRC. Was wore down to the copper, other 3 looked fine. Not sure what caused it, the rod had a black burn line around the inside under the bearing, in the middle. I replaced that rod w/ a good one ( had the machine shop check the big end and verify roundness). I do drive like bandit though

[csomni]

thats what happen to my #4 bearing , right down to the copper. the other three were ok too. notice it was knocking on start up. then you couldnt hereit till you steped on it. .

[Force Fed Mopar]

Yeah I could hear mine when I revved it, not at start up though.

i think im going to throw in new rings. whats the better hone to use the flex or the 3 bar

Flex, I never have luck with 3 bar types doing an in car re-ring.
