Default I really need help! Please read

I blew a line off my oil relocation kit (i needed one for my turbo). I found out it was off when i was driving because my motor started making a knocking noise so i pulled over to see what it was.

But here is my issue. *notice: the turbo is not hooked up* I Immediately put new oil back in my S, Royal Purple 15w-40. I performed a Compression Leak Down Test wich had a 2% Leak, Compression Test and my Oil Pressure is 75 psi.

I installed new Lost Motion Assemblies and a new Timing Chain, Tensioner, and both Guides.

But the knocking continues, and my car will not rev past 6,500 rpm. Has Idle Problems and has dead spots when driving. Im not throwing a CEL.

WHAT IS WRONG!!!??

Did the oil light come on at all? If you run the engine with no oil pressure to the point of starvation and knocking noise, I'd start preparing for a new engine.

No Check Engine light.. my stock oil sensor is not hooked up my Autometer oil pressure guage is. And The car WAS running Dry.. Im starting to think it is a bearing because i can take the car down the street and it drives fine.

tear it open to check it out, sounds like you toasted a bearing or two running low on oil.

friction multiply dramatically if you don't have oil in between 2 metal surface(and heat)

If you lost oil and did not catch it before knocking noises started, then you definitely cooked a bearing.

. Tear it down. Hopefully the crank survived.
