M54A1 Posted September 20, 2009 Share Posted September 20, 2009 Well I just pulled the head on the endt-673 in my 64 B613 to fix a small oil leak. I found no hone marks left in the cylinders, and a small ring groove at the top of the cylinder. The motor ran fine and started easy but had very low oil pressure when hot like 20psi WOT and 5psi at idle. When cold it would have about 45psi at 1800rpm. I thought my oil pressure was low because the oil pressure line was plumbed to the oil inlet of the turbo, but the worn hone marks and low pressure make me think I should rebuild the motor while I have the fenders and cab off. Any advice or recommendations. Thanks Quote Link to comment Share on other sites More sharing options...
