i just bought a eclipse gst and it knocks real loud. the guy i bought it form said the lady he bought it from had ran it out of oil cuz of a bad oil leak n the knockin started then. what might the problem be?
Answer -
I hope you bought it cheap. The knocking you hear is the connecting rods on the crank. Which means you need a motor. The bearings on the crank shaft have worn away because of lack of lubricant (oil). If you continue to drive it like this one of those connecting rods I mentioned will wink at you from the hole in the case it makes. You can try to rebuild the engine, but with the amount of damage likely to have happened, it's a lost cause. Junk yard may be an option... Not for your car! but to purchase a motor. It's a tremendus amount of work to do it yourself. I wish I had better news for you. The repair at an honest shop could run about $2000 to $3000. Let me know how it works out. Wish I could help you more

Hi again Aaron,
Lifters would make a ticking noise. Lifters can dry out and cause this due to the lack of oil and usually will quiet down when they refill, but knocking is definently lower end of the engine. We refer to the noise you are hearing as rod knock. As in connecting rod that goes from the piston to the crank shaft. Places like Auto Zone sell "short blocks". This is a rebuilt lower end and you would install your old heads, intake system, exhaust system, electronics and so on. Hope this helps.
Follow up: Well, tough decission really. Depends on what you paid. Personally, I would return it and get my money back from the guy that talked you into this mess. If that is not an option, then you need to fix it. If you have the money then have a pro do it. If you want to try it yourself, I will be glad to help you. It will be freaking tough, but we can do it. It would be a lot less expensive to do it yourself. Maybe a couple of hundred. But don't do this unless you have some type of mechanical experience. This one won't be like puttin' air in the tires... and will be many emails back and forth.
Follow up 2: Hey, check the oil and tell me what you see. Also, pull the filter and see what it looks like... Ok, talk to you soon...
AnswerI suggest you take it to a Cottman Transmission shop or a Pep Boys and have them listen. When rod bearings are shot the oil pressure is low. When you have the revs up the oil pump will bring up the pressure but when you let it idle the knock comes back.
