And yes, you can poke out the seal between the bypass filter and the
full-flow filter in the cartridge, which will result in low oil
pressure, although it's usually much lower than 1 bar at hot idle.

M117 engines can be a dangerous thing due to the potential for
head bolt thread failure, which necessitates drilling out and
installing threaded inserts (Helicoils) to fix. Part of this
operation involves the use of a special MB jig, as the head bolt
holes are not 90 degrees perpendicular to the surface of the block.

I am not knowing what running rich looks like, but will learn
more about that. Compression was 140 all around but for two
contiguous pistons with 130 and 120. That side also has very
minor head gasket leak. PPI indy found all this and said the
leak is a non issue at this point. The low compression is
probably due to kruff on valve that solvents will remove. Indy
says to just drive it and have fun. Rebuild or head work is more
than the car is worth. He says this to everybody and seems to
hate having people spend money fixing old cars. He is scheduled
three days out and has all racks loaded.
If I snag a cheap rebuild M117, that is cool with me. Or I wait,
enjoy and when it goes downhill, I get him to rebuild. He does
great work.

Poor compression in two cyls?
Gas dilution of the oel?

First of all verify the gauge reading with a separate oil

AFAIK for all Mercedes engines oil pressure gauge should be
pegged above
idle. If not it might be the pressure relieve valve or
spring, or you
might have worn main bearings.
Is there an issue with filter stem o-rings like there is with
the ON617?
