Chev 216 oil filter

[Ken Thomas]

Hi everybody, could someone tell me which two sets of head stud holes (picture one) the oil filter bracket shown in picture two goes onto. I think it is the two in front of the steam tube/temp gauge connection, but I am not sure. I do not want to assemble the head with the two special studs for the bracket until I am sure. I have retrieved the parts from different engines (not the NOS filter) & on one the “studs” were fitted either side of the steam/temp gauge connection, & this cannot be correct. I think the two studs go in the two holes in front of the steam/temp connection, but would be grateful of comment. Assembling the manifolds, carby & air filter may give me some indication, but I would rather be correct. I have tried placing the filter on another motor & it seems to fit inside the dogs box OK. Is there any issues there to consider.

Hi Ken

The on my HUP the filter mounts to the two on either side of the rear most intake. See photo on my Web page http://canadianmilitarypattern.com/H...20Page%209.htm

Will post directly on MLU soon.

There is also a service bulletin on their fitting on earlier trucks. My bracket had a torch cut notch in it that I've never figured out.

The two head bolts that it sits on are threaded at both ends, will try and find a picture.

Cheers Phil

Hi Phi, Thanks for your quick response. I look forward to your pictures.I have the threaded studs, but not a good set of the tapered nuts. I might have to make a set. The nuts & the bracket have rust damage, but it is the only one I have found. The bracket may be repairable, but I would like to get a better one.
I hope you saw my posting mentioning your advice re the oil alignment etc. Using your system & the addition of the grease checking, I feel I have got a good outcome.

Hi Ken

Here the photos I was looking for on the head mounted oil filter and part of the service bulletin concerning the New Larger Oil Filter.

Special head bolts



Location of the special head bolts. Looking at this picture I now remember why my mounting bracket had be notched to clear the temperature sensing port and steam relief tube connection. The head on my HUP had been replace at one time.




The normal location on a CMP for the temperature sensing port was back over the rear most exhaust port. In this picture you can see that my bracket had been torch notched to clear the different temperature sensing port location. (The numbers by the head bolts are how I remember to tighten the head bolts in the correct sequence.)



Attached are the primary pages from the Service Bulletins on the change to the larger filter mounted on the head.




Cheers Phil

System would not let me put all three of the Service bulletins in the same post, exceed the number uploads.

Hi Ken

I've seen something similar on a 216 but it was one that had been sitting for a very long time. It had been cranked through one revolution before the pan was dropped and there were similar groves cut through the sludge in the troughs. Guy I got the engine from warned me not to try and start the engine because he had destroyed another engine by not cleaning the troughs out first, the sludge plugged the scoops no oil got to the bearings when the engine started and it quickly seized the rod bearings.

As anybody who has put one of these engines on a test stand and turned the engine up side down before dropping the pan those little troughs hold a lot of oil, about a quart, which then drains out on the floor. This is also a reason that it is hard to get an accurate oil level reading the first time you fill up an engine that had the pan removed because the engine needs to run and then come to a stop with the oil pump turning to fill the troughs for the next engine start. Priming the oil system with a drill will take care of this when reassembling the engine.

Your method of checking for clearance and alignment looks good. When the engine is running the troughs do not hold much in the way of oil it is the spray nozzle hitting the scoops through as much of the swing as possible that is important.

I've done test looking through the fuel pump hole covered with a clear plate and you can just see one of the troughs, if you use a timing light clipped to the coil lead instead of the plug lead you actually can see (stop motion) the end of the rod and the scoop in the trough with the engine running.

At full song the combination of the scoops in the troughs and the spray nozzles the inside of a "splash lubrication" Chevy could more accurately be said to have "oil fog lubrication".

Thanks for all that Phil. Some really good info there. Just to be different, the nuts that hold down my bracket are tapered like wheel nuts. You might see that in the picture. They are about one inch AF. The bracket has a tapered seat in the hole. I am probably going to have to machine up a set. I had a long look at your site, amazing. Cheers.
