    Thanks. I've sold the Classic now so I'll see if they are available 'over the ditch' and let the new owner know.

    Re: RRC 3.9 not pumping any oil

    I worked on mine today... rebuilt the oil pump and filed it with vaseline. That did not work even though I almost burnt the drill waiting for it to prime (clockwise). I'll take the timing cover off tomorrow and check the timing cover gasket and apply suction to the oil cavity to see if I can get oil out of the pan.

    Let me know if you get yours to work!

    Re: RRC 3.9 not pumping any oil

    I had a similar problem when I rebuilt the top end of my motor. I actually ended up breaking a rocker arm trying to figure it out. I was fortunate to have PT Scram in town one day and convinced him to take a look. He showed me a plug on the oil pump just above the oil pressure sensor, I have a 1988 model with out the oil cooler so this may not apply to later models. He removed that plug and knew right away there was no oil getting to the top end. If you take that plug out and no oil is common out then your pump is not primed. I borrowed a vacuum pump from work, a HDPE sample port with similar threads, teflon tape(I think the threads are some weird British pipe thread), and the knock out from my break bleeder kit, hooked everything up,applied vacuum and voila I had oil in the KO container. Put the plug back in fired her up and a second later the valve train went silent and was purring like a kitten. Hope that helps.

    I believe this is my problem as I'm drawing old from the sump (there was more oil in the filter than when I filed it and if the oil when coming from the cooler, it wouldn't be fresh oil).

    It is my understanding that when turning the oil pump clockwise with the drill, I should be able to see oil flowing with valve covers off. I can't figure out what I could have done to block an oil passage when I did the head gasket job. I'm really confused.

    Re: RRC 3.9 not pumping any oil

    Any idea what could prevent the oil from flowing to the top of the engine when the pump is primed?

    blocked passages, by either sludge or improper head gasket, low oil pressure or low oil volume delivery, bad pump, internal failure of pump components i/e missing or stuck relief valve, low oil level in sump.

    I finally worked on it... looking at the time of this thread, a lot of time has passed There was nothing wrong with the front cover gasket. After putting another one on, I again primed the pump. I can confirm that the pump is priming (30 psi) but still no oil to the top. I'll go back down to the heads and see if I can figure out the problem
