Re: Low oil pressure in ZL-1
Aw shucks. Just glad Alss can get that ZL-1 running and really hammer on it. These motors are monsters and run real well when dialed in. Hey don't forget 427king mentioned the relief valve early on.

Re: Low oil pressure in ZL-1
Probably not the problem, but I bought an all rebuilt ZL1 motor and when dynod it had problems similar...The builder forgot to put in the 2 extra studs in each head that are only on a ZL1 motor...water was mixing with the oil and we had poor oil pressure when warmed up...after fixing problem, the motor dynod at 603 HP with LOTSSS of oil pressure!!! Bolts can be used if you cannot find the correct studs....but they need to be drilled and wiretied after torquing....hope that helps...good luck!!

Re: Low oil pressure in ZL-1
Im sure there is someone out there that read iluv69s post and learned something that may help them down the road and thats the important thing. Both air and water in oil can cause low pressure readings and foaming in case anyone encounters that again.
