2G Reusing Main bearing cap bolts?

[Xaveion]

I have a 98 GST 7 bolt engine I’m rebuilding and I was wondering if I can reuse my crank main bearing cap bolts, I’ve heard different things about reusing them and just wanted to get my own answers. Thanks

I've used mine before no problems.

The factory service manual doesn’t note these as “never re-use”, as it would for, say, o-rings or cotter pins. I would re-use them if it were the first rebuild on a stock motor that will remain stock in terms of power level, and if there were no serious issues with the old main bearings. If it was the second rebuild, or power was or will be increased much above factory, then I would not risk it. Plenty of folks go with ARP bolts or studs for high-power builds as standard.

Check the under head length. The original length of 7 bolt main bolt is 70.0mm, the limit is 71.1mm. Do not reuse if it is exceeded the limit or if it is close to the limit.. You can reuse it if the UHL is within the limit, but anyways it's cheap, so replacing would be also a good idea even if it's still within the limit or if you are unsure.
