RE: IML: 318 oiling issue

["Dick Benjamin" <dickb@xxxxxxxxx>]

I guess I could have made it more clear that the oil has to get up through
the correct (#2 or #4, depending on side) support tower and into the rocker
shaft in order to be distributed to all the push rods, and thus to the
lifters, so of course the right holes in the rocker shaft have to be
positioned in the right locations so the oil can get in there - thanks,
Mike, for pointing that out.

I was encouraging Jeff to check for cam bearing position because he
mentioned the engine had been seized, I thought there was an (admittedly
slight) possibility that the cam bearing had spun when he broke it loose.
Also, since he already has the head off, I thought it would be a quick check
to see if the oil spurted out of the right holes.

One further point I should have made regarding pumping oil at pressure
through the bearings etc.; he will have to reinstall the heads to get the
full benefit of this process, since there will be only insignificant
pressure until the oil system is all buttoned up. 

It wouldn't hurt to install a temporary "real" oil pressure gauge in the
sender hole so he can see what pressure is generated. If he has a healthy
drill motor, he should be able to see at least 40 PSI, assuming he is using
SAE30W oil.

Thanks Dick B, you saved me a ton of typing.  Its the rocker arm, the oiling

hole in the rocker isnt indexed with the one in the head so it isnt getting 
past out thru the rockers.  My first thought was a cam bearing indexed 
improperly, but unless the cam bearings were replaced thats not the issue. 
Otherwise the analysis of the oiling system flow is spot on, which leads to 
the rocker shaft orientation.

Quite often people will remove the shaft and rockers as a unit and then just

bolt them back on later,  that makes it a little harder to get them out of 
sync.  IF...if  they were removed and disassembled then the likelyhood of 
the shaft itself being incorrectly oriented increases.  At this point, id 
look at that shaft first and while I was at it, also make sure the rockers 
are oriented properly on the shaft - though that will not affect the oiling,

there is a definite left and right relationship of the rocker arms on the 
shafts.
