Neil: Did you put oil in the Filter before you installed it?.. Further on the type of oil issue, what ever you decide on avoid any oil that has the "starburst" marking on the container. These are oils intended for modern rollerized valve trains & are likely low in ZDDP.

Besides the shell Rotela, I would also use EOS from your local brand X dealer as additional protection, especially if this will be a cam break in.[/quote]



Still haven't seen any evidence to refute V. Schumann's claim that ZDDP additives don't mix well?

I am about to start up my 292 and I don't understand the talk about priming the oil system !! Is there something i should be doing ? I have no idea what type of cam I have is there a easy way to determine without opening up the eng. Also would a 10 - 40 detergent oil be the best to use ! Brand ?

You can tell very easily what cam you have by turning the pump CCW with a drill motor or even a hand-crank (speed wrench) ! (I can get 50 psi turning my stock pump by hand!!)



Pull your dist, use a 1/4 drive 1/4" deep socket with a long extension on it.



Have someone slowly turn the crank and observe the rocker assy's for oil. If you get oil flow all the time, you have a grooved cam. If you only get oil flow at certain crank positions, it's a cross drilled cam.





I am also going to do the modification that has been suggested here many times to pressurize the rocker shafts....







Oil. Just about everyone I have talked to suggests using any diesel type 15W40 oil like Shell Rotella, Chevron Delo 400 15W40, Mobil Delvac 1300 Super, etc.....





Cheers,





Rick

If you pull the distributor and use an extension and correct size socket and a power drill you can turn the pump CC  to pump oil all through the passages right up to the head prior to firing it up.Prevents dry start.I actually used the old oil pump driveshaft and a couple of parts from my nutdriver set and power dril  to prime the pump.I am using  Shell Rotella 15w40 on mine.If you do a search under "öil" there should several topics discussed previously.

Hi,

After some investigation, the cam bearings are part # F-9A, which are for a grooved cam, so I'm told.

The cam is cross drilled I think, I will have to pull it to be sure.

Could this be my problem?

Thanks,

Ed

Howdy,





I temporarily had a similar problem when I primed my newly rebuilt 292. I also have a cross-drilled camshaft. I turned the crank slowly while using a battery powered drill to turn the (CC) turn the pump.



When the holes finally lined up I got a LOT of oil at the rocker supply holes in the heads.



It's very possible that the cam bearing that allows oil to the heads has moved.





Regards,





Rick

Hi,



I have no oil to either side, I was turning the oil pump counter clockwise and I did have oil PSI at the gauge. I also tried cranking the engine over with a remote starter while I was priming the engine, still no oil at the heads.



I don't know if I have a grooved cam or not and my invoice from the machine shop does not say what cam bearings they used.



I guess I will pull the engine and see what is going on inside.



Thanks for you help,



Ed

Cam bearings made from soft material can shut off the oil supply to the topend in just a few hundred miles if the camshaft with the grooved center journal is being used.  These cam bearings get used simply because they cost about half what good quality cam bearings cost.  Priming the engine with the rocker arm assemblies off while slowly rotating the engine will help to verify if oil supply to the top end is existent or not.
