humm..after the intake ..or same time did you put in the oil pump..pump pickup set right? that top end oil runs thru /past the dist shaft above the geer ...were any gally oil plugs removed ...


I was not told that any galley oil plugs were replaced. Is there any possibility the new oil pump was improperly installed?

Kelly Mayo

still want to know when and why you changed the oil pump..

Andrew Olsen

The oil sending unit (sensor for the gauge) could have been messed with and damaged during the intake job. Have you replaced it yet?

Kelly Mayo

think he said that he check the gauge (another one) same issue...guess he fixed it.
