We will try to keep this list updated but if you do not see your engine listed here please ask!  We can  do custom stroker or knife-edge crank designs.  We can provide plastic templates for initial fitting and adjustment.

 

We have included some representative pictures of the scrapers we make.  If you would like to see a picture of a particular scraper please ask -- we would be more than happy to send one through.

 

When available (please enquire) our zero-clearance TeflonŽ scrapers run an additional $100.00 to the cost of the standard steel scraper unless noted.

 

Remember, your vehicle may have an engine made by a different manufacturer so check both product lines.  If you are still unsure, please contact us.

Some brief remarks about the M10, M20 and M30 engines with respect to oil control: These engines were designed with then contemporary elements, e.g. oil was allowed to drain onto the rotating assembly from the head.  BMW US patent number 4,773,366 for a "Non-foaming crankcase configuration for piston internal-combustion engines" illustrates some of the engineering philosophy changes that went into the families of engines that replaced them.  In 1994, SAE paper 940792 from FEV Motorentechnik, Aachen was presented that also goes over these design elements.

The crank scrapers we manufacture follow this design philosophy and extend it, particularly for vehicles that are used in extreme duty or competition (see "Kibort Effect").  We have had very favorable feedback over the years for these designs.  It is worth noting that the designs have been updated in at least nine generations over ten years which is extremely rare among aftermarket manufacturers.  The M30 design was one of our very first products and is part of our company logo.
