It's a shame that your '91 745 GL didn't have Bosch LH2.4 injection which was introduced a model year eariler in Jan 1990 as a free option.
'91 was at the very end of the switch over to the 940 designation. I assume it had a BxxxE engine which even in 1990 were being knocked out at a bargain basement price.
I would be interested in seeing a picture of the under bonnet if you can post one and, knowing what the original engine designation is on the white sticker on the top of the cambelt cover or even the 4th and 5th numbers (engine designation) in the VIN code after YV1.
