My 2000 jeep grand cherokee sounds like the engine is knocking, there is no oil presure, and it will not stay running. What do I do?
If you have this many problems with this engine I would suggest getting a used engine with low miles and a warranty you can get one for less than a 1,000 and installed for around 500-600 dollars. Once they begin knocking I don't repair them because you don't know about contamination in the engine from metal. And it's very costly to have an engine rebuilt. Especially with no oil pressure it's probably spun a bearing in the lower end of the engine.
