[Fot] Overheated parts

[Barr, Scott]

I have a set of Pauter rods and I turned one blue once when I spun a bearing.  I sent it back to Pauter for inspection and actually talked to Mr. Pauter himself who told me it was no problem.  Specifically, he said "You should see what those Porsche guys send back to us!"

I've now been using that rod with the big end turned blue for a 7 or 8 years, with no problem.

Maybe the blue colour doesn't mean that much.  When you have a new exhaust manifold, it will turn all
sorts of blue after a short run. Maybe, if the cranckshaft is not bent, or only minimal out of balance, the damage is not serious? Probably the Carrillo rods will be still as strong as before the overheating.

The oil pump broke in my TR4 and roasted the bearings. The Moldex steel crank and Carillo rods are not damaged but are now a blue color from being overheated. The machine shop is wondering if it is ok to use them. What are FOT thoughts? It takes 6 months to have another crank made.
