Glycol is a OEM Porsche bearing supplier, never had a problem in any of my motors... 4 or 6

Seen this many times on original bearings, after 40 years they start to delaminate.

Don our cars are aircooled

It's Glyco....not glycol:)

Woops, thanks for the correction Mark

I never had any problems either...after 40 years, I would hope I would have driven it enough to warrant a rebuild, or would freshen it up to keep it a happy motor. No garage queens here!

....................It would be helpful if additional information was available, such as 1. how many miles were on the engine. 2. if/ or when it was rebuilt was it TOTALLY rebuilt or did it just have a top end job. 3. Did you ever run low on oil.?.4. what do the ROD bearings look like?, are they also scored or flaking bearing material?.
