Hi Taffy
I was told that SKF have started to manufacture in China and so went away from them.
It was a new Japanese NTN about 45 hrs ago, just the open variety no seals. It was a C3 and all that - bad call.
The hardening on the bearing inner ring was gone on the area where the lobes would be pushing valves - makes sense cos this is where it would be under load.
The top end was getting oil and I change it often.
I think its the later model cam. I got a secondhand 1 after wrecking mine due to rocker bearing (the cause of the rebuild 45 hrs ago) and its got rounder lobes than my old 1.
Do they all have the same lift?
