main&rod bearings
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...

:eek: 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? dcb |

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. |
What pulley are you looking for, AND are you sure it's not a cracked flywheel?

no i haven't had a chance to check the flywheel but i will as soon as possible. i need a crank pulley. |

If you think you are having crankshaft issues, I'd stick with a stock vibration dampener. |

took care of the whole pulley thing.(thanks tom!) i'm gonna check my torque converter bolts and make sure there tight and if they are then the problem will have to continue till something shows it's ugly head:rolleyes: i'm gonna try a heavier oil when i change it next and see what happens too. any other suggestions are welcome. thanks

Cracked flexplates are more common than bad bearings. Main bearings sound like a thud and rod bearings usually make noise around 1500-2000 rpm and slightly decellerating. Rods are a kind of rapping noise, flexplates clatter at idle or just above, generally.

Are you sure the oil isn't overfull? It is a boxer engine, you know. (A pat on the back to those that understand how that would come into play here.)
p.s. Mine also thunks a bit when cold. Just let it warm up a bit. |
