main&rod bearings

Budfreak · #1 09-21-2005, 02:08 AM

how hard is it to replace the main and rod bearings? it looks like it could be done with the engine in the car. the knock i've had when cold is sounding louder and i'm really thinking i need to do the bearings. anyone know a place to get a good price on them?

The engine has to be removed and completely disassembled and the case split to replace the bearings, not a job for the faint of heart.

I was gonna say on a scale of 1 - 5.... You're looking at about a 5.... That's probably almost as hard as it is gonna get... taking the engine out, splitting it open, replacing the bearings and putting it all back together again so that it will run again... Definitly possible.... But with the engine open, you will need to take certian precautions so as to not damage any of the internals...

well, i guess i just drive her till she dies then. i can't possibly afford to get it fixed and i have nowhere and no time to do it myself. i'll just worry about my pulley and keep the oil change but i'm pretty sure it's a bearing going bad so my time as an svx owner may be limited now.

Be on the lookout for a low-mileage, salvage engine. My guess is a transplant would cost considerably less than a teardown/overhaul. You could keep the old motor and work on it as time and funds become available.

You're sure you're not just hearing that lopsided crank pulley hitting the timing belt cover?

Ah throw some valve medic in it and turn up the radio.

Oh yeah when the old is out send it to Dave and I and it'll get rebuilt into a NA 300hp engine that you can brag to your friends about (granted it'll be in our race car then)

yes i'm pretty sure. i was laying underneath it yesterday and could hear it pretty good. from the top of the engine it sounds like the knock is in the back of the engine. i figure that pulley being like that has probally put alot of stress on the back bearings and there failing. i'm searching for a pulley now although i can't afford one for 3 more weeks.

BTW, the knock goes away or just gets really quiet as i think i detect it every now and again when it's warmed up all the way and been driving a few miles.
