It was the oil pressure switch

What are the odds that the oil pressure switch would fail RIGHT AFTER I put a new o-ring on the oil pump cover.

New switch, everything back to normal... <<< NOT really, see below...

... and, I won't need any laxatives for a while because THAT scared the crap out of me.

What's the "normal" oil pressure suppose to be?

All I can find is the pressure for the switch which is something like 3 to 8 psi.

Suspect the oil pressure switch, trip to Irv Seaver's for a new switch.

A general rule of thumb I've used for most motors is about 10-12 psi for each 1k rpm at operating temps. Slightly higher if not up to temp yet.

Puke Oil Pressure Dropped to 20psi... this is going to be expensive.

Okay, this may not have been one of my brighter moves but I really wanted to ride my BMW today...

Everything seemed fine when I started her up this morning, well, except that sticking float in the left carb...

I ride down and meet my friend for coffee. So far so good. As we head out and the engine warms up fully I notice that the YELLOW light is flickering at stop lights.

Now, a wise man would have taken the bike home immediately, but not me, I motor on.

We end up getting stopped at every stop light from here to there, and the YELLOW light still flickers, so I start holding the idle at 2K at the stop light to keep the light out.

We stop briefly to talk with a buddy, I turn the engine off for less than one minure, upon startup the YELLOW light is on ALL THE TIME for a few seconds and the engine makes 4 or 5 loud rattling sounds... light goes out engine returns to normal sounds and I start praying that I didn't just destroy my engine.

I ride home and avoid as many stop lights as I can and end up back at the garage, where I should have gone in the first place.

Put the oil pressure test gauge on the hot engine and I only get 20 psi at 4K.

At this point the BMW is grounded until I can fix this.

PS
What the heck was I thinking... I feel sick now

Tink, time to take the oil filter cover off and see where the O-ring is.
I cant imagine this being related to resealing the oil pump cover or replacing the RMS.

Let us know what you find.

Kai Ju,

For now I need some time to decompress. I have put off too many other life responsibilities to get the BMW back together. So, for now I'll drain the gas and put her to bed until I have time to devote to her again. I was really hoping that after the rear main seal and clutch she would be a reliable runner and I could just ride her and enjoy her... but she broke my heart today so I need some time away.

When I do resume work on her I will first return to the "seen of the crime", the oil pump cover. I'll also pull the oil filter, and the pan to verify the status of the oil pick-up pipe. Would like to check the pressure relieve valve too but have not yet done any research on just how to do that.

I hate to think I've damaged the engine, but I need to be prepared for that if I did. That would mean a long complex inspection and repair of the engine and I'm just not in the right frame of mind right now the worry about that. For now I'm going to focus on fixing the oil system.

I have two working theories... 1) the oil pump is some how to blame, and 2) some dirt was dislodged during the o-ring install and found it's way down the oil system and has lodged itself in a critical spot; i.e. oil filter, oil pick-up pipe, oil pressure relieve valve. In either case, the search for answers begins at the oil pump.

I'm starting to have a real love/hate relationship with PROJECT-S... I just know it will get better sooner or later.

Truckin'

Until I figure out this low oil pressure issue, this is the only way PROJECT-S is going anywhere. Just a test fit today, going to truck her to work Friday for the annual car show. Many people at work know about PROJECT-S, but no one there has seen her yet, as I do not want to commute on her.

Oil Pressure Thread

I made a separate tread about my oil pressure SNAFU > http://www.advrider.com/forums/showthread.php?t=896416

I now know that the BIG o-ring goes on the BIG part (a/k/a flywheel) and the LITTLE o-ring goes on the LITTLE part (a/k/a oil pump cover).


All is well again with PROJECT-S and I can now go back to just riding and enjoying her.

Thumb Good to Go

Just got back from a 50 mile test ride down PCH to Laguna Beach and back.
Project-S is running great. No more oil light issues.
She hums along like a fine German sewing machine.
No other issues to deal with... for now.
Now I can just ride and enjoy her.

What next? Another build, hmmmmm...

Stopped by Roland Sands place this morning in Los Alamitos (about 10 miles from my house) to take a few shots of PROJECT-S. Funny, no one was there at 7:30am on Saturday morning

Angeles Crest Hwy / Newcomb's Ranch

Rode up to Newcomb's for breakfast this morning. First time up Hwy-2 for PROJECT-S.
Long (no so) high speed sweepers, this is what this bike was built for.

Apologize for the poor quality photos, took my cheesy pocket camera and shot in a mixed lighting situation without fill flash. That will teach me to bring one of my Nikon's next time.
