Re: Manual transmission causes crankshaft wear!
Ok, so yesterday and today I was able to speak with a respected Subaru ,mechanic who works at a "big city'' Subaru garage and he has never heard of this problem. As background he runs a 500+ HP Impreza. Nuf said.
Any way although he agreed with the idea of the wear could be caused by the clutch, he had not seen it himself. He also said that the five main bearing 2.5s have only one thrust bearing. I will verify that at the local Subaru garage perhaps as soon as tomorrow.
HOWEVER when I mentioned that the engine had only used 10/30 Mobil1 oil, both he and his friend, another racer freeked out and said that Mobil1 is too thin for a Subaru engine!?!?
They both recommended Rotella 5/40.
So when the new crankshaft goes in, Rotilla goes in too.
More on this later.
