Hi,

Question regarding the main bearing studs. The bottom end of my LS1 is totally stock. I was installing the windage tray and over-torqued one of the studs, breaking off the top.

What are my options? Remove all the single stud and replace with OEM? Remove all the studs/bearings and replace with OEM or something upgraded? And, what is the right torque spec for the windage tray?

The motor was a takeout from an auto trans GTO and has 40k street miles. For the past 2 years it's been installed in a 944 track car. It's running headers, medium cam, springs, lifters seats, upgraded oil pump.

Thank you in advance for your input.

What I would do?? Just pull the stud and swap it out, torque to spec.

I beleived I torqued mine to 22ftlbs

 

Windage tray is 18lbs! i just did mine last weekend.

 

Yes, just verified on LS1Howto. 18flbs. Mine were top lock nuts too.

 

Thanks guys. So it is safe to replace that one stud?



Appreciate the advice.
Dan

 

There is no problem replacing 1 stud, you will be fine.
