    Where from? Take a long screwdriver, broom handle or stethoscope and listen to various places on the motor while it's running. If the noise comes from down low by the crankshaft it's a crankshaft bearing. If it comes from the cylinder head it's a cam problem. If it comes from the top of the block beneath the cylinder head it's a piston pin, cracked piston or possibly just carbon built up inside the compression chambers. WATCH OUT FOR MOVING PARTS!!! Good luck,

These things are notorius for having weak oil pumps. get one through Carquest auto parts. They can get OEM part through their World Pac division for 1/2 price of Jaguar. Alot of people say the heck with it and put Chevy 350 in it's place( It's a popular thing), and they love it that way.
