997 3.8L oversize crankshaft and connecting rod bearings

[Marc's 911]

Hi Loren / everyone,

could you tell me whether there are oversize crankshaft and/or connecting rod bearings suitable for a 2005 (MY2006) 3.8L (997 Series 1) engine. I am aware that genuine ones don't exist but maybe aftermarket ones.??? Your help highly appreciated.

regards

Marc

I believe F6I was talking about developing some, however I doubt that will happen or has happened.

Generally speaking, if you need oversized bearings you should be instead looking at replacing the crankshaft & rods (and possibly bearing carrier).

Thank you for your reply. I was trying to see if I could avoid going that way due to high cost of those parts.

Have you measured your crank?

Have you measured the rod big ends?

Have you assembled the carrier to torque spec without the crank and measured the bores?

If you are over 5 thou clearance I would not try to re-use those parts, even with oversize bearings, you are just asking for trouble... there should be no good reason why the crank would be worn to that point (and if there was a reason, i.e. spun bearing, the integrity of the crank is questionable at best).

Will get the exact details from my mechanic and let you know
