Not to cause an argument here, I really wasn't planning on posting any time soon but one comment I really disagree with...
''Normally you would retire a race bearing after 10 - 15L anyway''
Are you serious dude?
40 litres is laughable in most RB and Nova engines that I've seen.
Hell I've got a 17 litre old one here... Not an ounce of play in the rear bearing. Then again it has been run on some of the best fuel in the country...
Don't take offence... If there's something to back up your statement I'd like to hear it. I'm curious.
Cheers
