Hi guys first time poster...long time reader.

I've been looking around and can't really figure this one out.

It started with the car dieing one morning to work.
Had it towed home and I checked the voltage on the battery and it was good
But I have a charger so I charged the battery over night because it wouldn't start.

Well this morning I started it and got a horrible sound coming from the engine.

Oil level was normal

That's rod knock. Needs new piston rod bearings.
Or..crankshaft has "walked" and connecting rods are contacting the bottom of the cylinder walls.

Yeah, that's the sound of money leaving you.

Either rod knock or valves tapping pistons.

Either way, it's gonna be 'spensive.


IF you have access to cheap labor, and can find a good used replacement engine, you might be able to get the job done for a reasonable price.

Is there a college in your area that has a vocational automotive program? If so, contact them and ask if they would be willing to take on an
engine swap (or engine rebuild) on your car. Sometimes they'll take this kind of work on and typically you only pay for parts. The labor is free
as it's a class (or student) project. While the students may not all be great mechanics, the work will be done under the supervision of good
instructors so you don't really have to worry about that.

I know a few people who've had big ticket repairs done for parts cost only courtesy of the local vo-tech automotive program.

An engine swap might be cheaper and more practical than trying to repair the engine. Your best bet, I think, is to find a low miles engine
pulled from a car which was retired due to collision damage but with no front end damage.

Check the salvage yards that are local to you.
