Dropped the lower oil pan. The good news is that I have a bolt from the oil pump. The problem: There are a total of 8 other bolts that I can't see where they are from and I need your help. I've posted pictures showing these bolts.

RealOEM is not very helpful in showing where these are from. They are all 10mm heads, and my fear is that they are from somewhere higher and out of reach with only the lower pan removed. I do not have the ability to drop the main pan from where the car is at right now.

Additional pictures can be taken of the oil cavity upon request.

From the last picture, it seems the 10MM headed bolts hold the oil pump together as I can see at least 2 places they should be.

Yeah, but the problem is....there are only two empy places for bolts to go, and 9 bolts that I need to account for. The large one is clearly off the oil pump mounting. The smaller guys-- I really don't know.

At the very least, it would be nice to know that I can get the bolt or two installed that I can see missing installed and drive the car around somewhat until I can lift the engine and drop the main pan to see if the bolts are coming from that area.

I'd say they could be from the upper oil pan to block as well as for the oil pump. See link below. Many of the upper pan bolts are secured from inside so if they loosen and fall out they'll end up in the lower pan.

There are 9 bolts fastening the two halves of the oil pump together. 8 short ones and one long. No. I was wrong. There are 11-6 mm bolts, 10 short ones and one long.





The big 8 mm bolt came out of one of the three in the following picture.



The new gasket is no longer cork. It is aluminum and looks like this.

I've been seeing this message frequently and I've been told its nothing to worry about but I thought I'd post to see what you guys think.

the OBC throws an oil pressure warning generally at idle and with increasing frequency as the car gets hot. I've got a '94 540 converted to manual.

Is this something I should be concerned about or do I just deal with it?

I'd appreciate some tips for the conversion from you. I've got the parts package in my garage from a 83k 95 540 6 speed ready to go ahead when I have some free time. The V8 and automatic transmission are not removed yet.



How difficult is it to remove and install the pedal and bracket? Do you remove the instrument cluster?

WOW! Good thing you didn't decide it was just nothing =)
