If the oil distributor valve spring is modified to raise the indicated pressure it will result in insufficient flow to the rods and damage will likely occur. | | | | | Joined: Nov 2012 Posts: 41 Wrench Fetcher | | Wrench Fetcher Joined: Nov 2012 Posts: 41 | bought truck it was used as a daily driver took it apart 10 years ago it was running then but the engine smoked rebuilt last fall checked bearings new rings head was cracked thats what the smoke was rebuilt head motor runs fine other than the oil pressure using gauge in oil line port not the original gauge trying to get it mechanically right before putting body on retired pipefitter most things loose pressure upon heating except steam will torque head and run it again today dont think the spring was altered i didnt and dont remember what it was | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | "bought truck
it was used as a daily driver took it apart 10 years ago it was running then but the engine smoked
rebuilt last fall checked bearings new rings head was cracked thats what the smoke was rebuilt head
motor runs fine other than the oil pressure using gauge in oil line port not the original gauge
trying to get it mechanically right before putting body on retired pipefitter most things loose pressure upon heating except steam
will torque head and run it again today
dont think the spring was altered i didnt and dont remember what it was"

| | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | Say speeeeeeeeed! The oil pressure when a 216 is cold will be about 25-30psi. The oil pressure when a 216 is warmed up will be about 14-15psi. The oil pressure when a 216 is idling will be about 6-7psi.
Anything other than that indicates either a problem somewhere in the system or that someone has modified the system in some way other than stock, in which case he or they have assumed the title of "head engineer".

No problems in five years. | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | Not unusual Tom. Probably attributable to the bearings being worn some. If you ever have a need to pull the pan down it wouldn't hurt none to reshim them. Might bring up the pressure a bit. Don't cost that much to pull the cover off the oil pump and see if the gears are worn or if the bottom of the housing is showing any wear. Really a simple pump and you can get rebuiling kits for them. It's also possible that someone put a homemade gasket under the cover which would lower the output due to to much clearance (pressure leakage) at the ends of the gears. Denny G

The purpose of this forum is to share information, and even the most laid back (and permissive) of us have difficulty reading your posts and understanding what your questions and problems are with your oil pressure. That is why you got the response from some of the posts earlier in this thread. Even the most finicky of us will sometimes have a typographical error, and are usually forgiven, as long as we can communicate. Here, you have access to some of the best advice possible, with many willing to give you a hand. You just need to help us out a bit.
I am really glad you found the problem and shared the solution with us. That is something for all of us to keep in mind next time we have a similar problem.
