FYI - Camguard and Continental Motors

[n761tj]

Continental Motors will begin requiring the use of Camguard in all of their Mattituck overhauls and repaired engines to maintain their warranties.

The formal announcement of our relationship will be announced at Sun n Fun.

Hi Ed... What do you know about A9? http://www.aprobertsarts.com/clients/ace/a9-2/

[SHIPCHIEF]

What area of the engine is effected?
Lycomings were camshaft & lifter related, but Continentals have the cam below the crank, so the cam & lifters seem to get plenty of oil, and are not too near the crankcase vent where moist cool air can rust the cam during prolonged rest periods.
My O-470 has had a couple of cylinders off due to valve guides, both times the exhaust valve was replaced, one also needed an intake guide. Could this be the problem Continental has in mind?

I use Camguard and love it... have for years.

Hmmm... no comment, A9 must be some good stuff.

Lycomings suffer more from lifter and cam rust pitting and subsequent spalling. They also suffer more valve sticking problems (deposits).

Continentals have more cylinder problems including low compressions from ring and cylinder wear and as you indicated, valve guide wear. These problems are due to deposits in the ring grooves and valve guides. They also suffer lifter spalling that I believe is related to flawed break-in procedures. It also affects lifters during break-in of a new (repaired) cylinder or cylinders. Mitigation of these problems is exactly what Continental has in mind, and the commercially available oils have demonstrated they are not up to the task.

Here is Continental's first statement.

Mattituck Services, a subsidiary of Continental Motors, has entered into a partnership with Aircraft Specialties Lubricants to study the potential benefits of continuous long term CAMGUARD use. The study will last approximately 18 months and will be limited to specific engines overhauled or repaired by Mattituck Services. Customers that wish to participate in the study will have very specific conditions and compliance requirements. The study will not affect factory new or rebuilt engines produced by Continental Motors. No specific details of the study are available at this time.

Just curious, what was the results of the camguard test?

[scsmith]

What about Shell W100 PLUS?

Is the Shell additive the same as CamGuard, or very similar? or??

The additive in the Aeroshell Plus oils and its W15W-50 multi-vis oil is the Lycoming LW-16702 anti-scuff package. I just noticed this Lycoming SI also.

See this post by Ed Kollin on the differences between the two:

Phillips new Victory oils also have the Lycoming LW-16702 additive package.
