Question about 1993 Chrysler Lebaron

Loud engine knocking

I have a 1993 Chrysler LeBaron. I was told it just had the heads replaced. It has a loud metal to metal knocking that gets louder with acceleration. I can drive it for a short time then it dies. Once it cools down it will start again. I pulled one of the valve covers and found that only one of the lifter appeared to be damaged. I do not have any fluids leaking - Oil, fuel, coolant. What is this I cant afford to replace the engine. Do i just replace the lifter? Do I need to replace the valves? Rod bearings? How do I do these things?

Your freeze plug on the back of the block i had the exact problem its easy to check before you start it up to drive run a garden hose in your radiator and turn it on and look under the car if water is going every where you need a new freeze plug and there 3.99 at any advanced and you need to ask for a rubber fgreeze plug there way better.

Valve/lifter problem will certainly sound that way, however it should not necessarily make it overheat. You didn't clarify which engine it is, since valve covers could be removed easily, maybe 3.3? If there is a damaged lifter, then there is going to be metal filings in the pan, so if you fix the problem, oil and filter will have to be changed. It sounds like maybe they did not install one on the valves on that head correctly and maybe not the heads were installed right. You could even have piston damage from that valve. I would suggest that you take it to a mechanic to look at it if you are not capable of fixing it yourself. If you can't afford the repairs, there is always cars out there for that run good for what it would cost to repair yours if the motor has to be torn down. Rick

Can lifters be replaced

Oh yea, lifters can be replaced , best if you replace cam an lifters together ! Loud knocking is not usually associated with lifters , they usually make a ticking noise ! Knocking noise is most usually in the bottom of the motor , main or rod bearings . most of the time rod bearings !

Engine knocking, valve ticking loud in engine, when idle or drivi

Make sure the oil level is good, and have the oil pressure check by a garage or someone who can, by using a external gauge to see what the actual oil press is. Low oil pressure will give you the ticking, start there.

Car has loud knocking sound. gets louder with rev of engine.

Here's what you don't want to hear...A loud knocking noise from inside your engine is generally caused by a crank or rod bearing...when caught very early, sometimes they can be replaced. however, once the noise is loud, the attending crankshaft journal gets "hammered" out of shape and the job becomes very expensive and in most cases more costly than engine replacement. There is one other item that can cause a loud knock...your flywheel. Bearing problems generally cause low oil pressure. If you have that, it's gone...if not, have the flywheel checked before sending the engine to the scrapyard.
