We can  do custom stroker or knife-edge crank designs.  We can provide templates for initial fitting and adjustment. Templates cost $100 and are a separate charge from the scraper pattern chosen.

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 Teflon® scrapers run an additional $130.00 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.

V6: Mitsubishi 6G72, 6G73 There are a number of variants.

4-Bolt 6G72:

The dual scrapers ($99.95) work on both the up and down stroke.  The tight clearances of the girdle to the inside of the pan dictate that the scrapers have varying coverage from the first through third bays.  The scrapers are made from 18 gauge steel and are to be sealed with RTV silicone gasket material.  Either version of the windage tray below runs $264.95.  Note there is another design for two bolt blocks -- see below.

Below: the prototype set:

Below -- the main bolts are installed and torqued and then the screening insert is installed.

(Girdle is not included)

The windage tray covers the entire rotating assembly with directional screening.  The screening strips oil away from the rotating assembly and allows it to pass through to drain to the sump.  Simultaneously the screening shields draining oil on the floor of the pan from being hit by high speed droplets of oil and aerated:

The windage tray is designed to use the 16 stock bolts.

Two bolt 6G72 or 6G73: The dual scrapers ($99.95) work on both the up and down stroke.

Windage tray -- this tray was designed to clear the many variations found in the two bolt girdles over several generations: $264.95
