Ok.. I had a slight issue with oil pressure loss, it totally screwed the bearings in the lower end. I can't afford a full rebuild at this time, so.... can I jack up the engine, remove the engine cradle drop the oil pan, and replace the bearings on the bottom end and the oil pump and pickup.?????????????

My car runs but has a tapping in the lower end... I just want it back up and drivable.

Any help appreciated.

 

Carrier bearings are in your rearend.You can change your rod and main bearings for relatively cheap,just make sure the crank journals look alright and you should be ok.

 

Am i wrong or dont you need to have your motor out of the car to change those bearings?

 

That is what i would like to know..

 

Experts chime in anytime.

 

I believe most engines, you can replace the main bearings with the engine in the car.. It's a PITA, and you should probably rebuild the entire thing, for the simple fact that if you had/have an oil pressure issue, it's not going to be resolved by just swapping bearings.. On top of that, how do you know that your crank is going to be good, or your cylinder walls aren't scored, or even your cam isn't flattened out in a spot from lack of oil getting to the heads??

I realize that's not always an option, but think a little further down the road, when more problems arise... You're going to replicate effort for no reason..

you can do that but, you have to mic the journals that you find with bad bearings, you should probly just take it out, go thru it the rite way

 

Its going to be rediculously hard to do that with the engine in the car. Do you at least have a lift to do it on? You'll need to remove the crankshaft to inspect it properly, and that requires removing the transmission/clutch/flywheel. You can't just throw new bearings in there and expect the engine to work properly. If you've got spun bearings you've more than likely scratched the crankshaft, which means you need to have it polished (polishing is cheap, about 40 bucks). You have to bring the crankshaft to a machine shop to have it polished (or buy a new one).

In all honesty, it would be easier to pull the engine out than it would be to drop the k member, hold the engine up and work on it from underneath the car. I considered what you're thinking about when I replaced my shortblock (because of spun bearings). Once I really thought about what I was doing, the obvious solution was to pull the motor. It was fairly easy to pull the engine out, swap everything over (I bought a used, stock shortblock) and put it all back in. Its not as hard as it looks, you could do it in a weekend provided you have the parts you need.
