We had another annual tech session at our shop on Saturday, March 28, 2015. (click on the picture to see larger versions)
Nice spring weather at Integrity First for our BMWCCA tech session

First up was a quick lesson on fasteners, their materials, the advances BMW have made, and the importance of torque specs.

Inspecting fasteners
Our second topic was all about BMW’s cooling systems. Including water pumps, system bleeding, electric water pumps, and why thermostats can set check engine / service engine soon codes in the engine computer (DME).

(whilst waving around the cool air-lift bleeding tool)
Our last topic focused on BMW’s V8 engines (did you know BMW used to make pushrod V8-engines? – don’t worry we didn’t either)… We covered the strengths and weaknesses of the M62 series V8s including a dead 4.4L and a dead 4.6L

Checking out a stripped down M62 – this one is a 4.6L

A bad N62 problem: excessive oil consumption due to bad valve stem seals
There were no shortage of cool BMWs visiting – check out this beautiful 6-series!
Dan brought the rear-end from his M3 for “show and tell”
A special thank you to the Utah BMWCCA chapter and to Michael Bontoft for the photography. See you next year!
