A while back, I posted about a squealing noise my 216 was making. Today, after not running for 3.5 years, I have finally tracked it down to the exhaust valve on cylinder #3. It appears to move normally, but screams in agony on every stroke. I have not noticed any oil coming to the rocker shaft and my oil pressure gauge doesn't show any pressure. I don't know if the gauge is good. How can I check to see if I have any oil pressure?

Thanks folks!

Could be the gage is correct, have you had he distributtor out of the engine? Check and make sure it is properly seated in the slot of the oil pump. If it is not the pump will not turn.

I would try a different gage.

Keith, I suggested checking the pump as it seems that there is no oil flowing to the rockers and he has a dry valve stem. The Gage could be right but that would indicate no oil flow and it is very important to get oil to the rockers, the second thing I would check of course would be the Gage .

We can only assume so.His description sound like a discussion of a running engine not pumping oil.

Yes, the car is running. It got driven onto the car transporter in California back in December, 2015. When it got delivered to New Mexico, it started making the awful squealing noise so I parked it. It has been with two body and paint shops before that work got finished. All bondo, some of it 2" thick, has been removed and it's now all metal again with beautiful body and paint work. I tried to have it drivable for national "Drive your woody day" on May 18, but didn't quite make it. I'm going to put a 261 in it later this year but would like to get the 216 usable in the mean time. So, I'm looking for help on debugging my upper end oiling problem.

Personally, I would not start it. I would remove the distributor and work the oil pump with a screw driver chucked in a drill., which is pretty much in keeping with 2blu52's comment.You can check the gauge and the amount of oil making it to the top end...if any. Then trace it backward until the problem is discovered. You can remove the top oiler pipe at the rear of the oil distributor on the left side of the engine to see if oil is at least getting that far if you discover none at the valves.....but by no means disconnect the oil pipe inside the push rod cover. The hex fitting in there looks tempting to undo, but if it is an original fitting, you will do damage backing it out...as that fitting is normally soldered.

Update:

I removed the rocker shaft assembly and observed there is NO oil coming out of the tube up through the head that connects to the oil loop in the middle of the rocker shaft.

What should I look at next? Dropping the oil pan?

Thanks for any/all suggestions folks.

I just fixed one where oil delivery tube in the side lifter gallery was blocked, at the junction where it goes up thru the head, this engine had the same symptoms, but did have oil pressure.

More info:

I pulled the distributor and ran the oil pump with an electric drill. It took a while, but after about 30 seconds oil DID come out of the tube that connects to the rocker assembly. It was a steady small volume flow with no bubbles.

Seems like the next step would be to reinstall the rocker assembly and see if I get any oil up there now.

Any idea why there was no flow before?

2blu52 may have had it right in that the distributor was not properly seated in the oil pump. As a precautionary step, if it were me, I would remove the top oiler pipe where it exits the the oil distributor on the left side of the engine and make sure there is good flow through that pipe. To be sure....the pipe that exits to the rear of the oil distributor [kidney shaped plate - left side] is the same pipe that comes out of the right side of the block inside of the lifter / push rod galley, up through the head and finally to the rocker arm assembly. I would insure that it is unobstructed and that oil flows freely through that pipe. But again, DO NOT disassemble it inside the lifter / push rod galley. If you determine that oil is flowing to the rocker arms and you still get a squealing noise, sometimes bend push rods can also cause a kind of squealing noise.

Did you make sure the inside of the pushrod tube is clean and open?

All of the 216s I've dealt with had solid pushrods. I don't think hollow pushrods were used until the V8s as a means for getting oil to the top end.

I meant rocker arm tubes. Senior moment.

Don't expect a lot of oil pressure. My '51 216 ran about 7 psi on a good day. It still runs fine but I switched to a '53 235 for the full pressure oiling system. Those old babbit pounders are tough. I kept mine below 60 mph with a 4:11 rear end. Also, while you're trouble shooting, keep every thing wet with a pump oil can. Good luck

Update: Oil now flowing!

Ran some Marvel mystery oil through everything and now have somewhat feeble flow up to, and through, the rocker arms. I'm going to pinch the return tube to try to increase the flow through the rockers. Then, I'm going to button it back up and see how it sounds.

Wish me luck!

This is a metering fitting as part of the top oiler system on a 216. There is a small hole in this fitting that restricts the amount of oil that gets to the rockers. You might back out the line a this point and check if that orifice is clear and open.
