I was at the local drag strip last sunday. And, I made one pass no problem but didnt run a very good time. Then ran again like 30 min. later and It ran good. I launch at 4800 it hooked then started spinning. At the end of the run it died so I cranked it back up and died again. I cranked it back up and kept it running by keeping my foot on the gas. The motor was making a Knocking noise and had 10 psi of oil pressure. I turned if off after I noticed that the car was making a knocking noise. The car is a 1998 Z28 6sp. has a tsp cam, ls6 intake and a ls6 oil pump. I put the cam, oil pump and intake on December 25. Need Ideas what is wrong.

 

ttt need ideas I hope maybe the oil pump is messed up.

 

hopefully its the oil pump

 

I do hope I will know shortly.

 

If it was knocking loud it was probably a spun bearing. Change the oil and see if any metal comes out the pan.

 

it's not really loud it is coming from the front

 

like strokedls1 said, change the oil and check for metal shavings. might have spun a bearing, or worse. at least it cranks tho, thats a good sign.

 

My guess is spun bearing. Low oil pressure and a rythemic knock that speeds up with rpm is not a good sign, how many miles on the engine?

 

about 80,000 Has no oil pressure at start up.the top of the motor is what is rattling

 

I got the oil pump off last night and thier is hotspots all over it. I just put the oil pump in last December.
