Re: M90 questions

I was concerned when my motor was rebuilt as even if they skimmed the head the block was also surfaced so I bought an adjustable timing gear just to be safe. It was years ago, but I think I paid around $100

Re: M6 front brake caliper

I just rebuilt some early euro calipers and couldn't get the pistons out for the life of me. I took them down to a shop that does clutch and brake supplies/remanufacturing and they got them apart. He said they had to use way over 200#s of pressure to blow them out. When they came apart the pistons a...

IIRC the last year of the M90 was model year 1981. An 88 block should not be an M90

Many times when a bolt or nut is stuck, try to tighten it/"crack" it first which can break it loose

Re: H&R Lowering springs for the late model 6

They are being mis advertised. They early cars, pre 82, and the E28 chassis cars take different springs., The proper springs are available all over Ebay at an average price of around $275 IIRC for top brand names

Re: WTB M90 engine block from 77/78

All M90 blocks are basically the same through May 81 . The only difference being, that I am aware of, is the later block does not have a raised water passage. I have one of these in my car Bore and stroke are the same early and late. Early head will fit the later block

Re: lowering springs

If you read offerings of springs for sale they all state a 1.25 -1.30" drop regardless of manufacturer leaving themselves some wiggle room. I have B&GS and it sits like the pictures on 17" wheels

Re: Heater valve

Walloth and Nesch, in Germany, has them for $135. The part number is 64111360820 which is a BMW number if you cross check it in reaaloem. The picture they show partly shows the label which says made in Germany. They appear to be better quality than the original as they have metal reinforcing clips a...

Re: Which fuse?

on the early cars these lights pass thrrough the emergency switch so if it is bad they will not work. I am not sure on the later cars but you may want to check on that.
