rebuild LS1 vs switch to LS2
My LS1 01 ss M6 has started burning oil 61000 miles, was always driven easybefore we bought, then we started driving harder near redline and then blue smoke.
Had comp checked was all 170 -175, cyl 5 had fouled plug with 180 psi.
Conclusion ? broken rings, bad valve seals?
If I pull engine to freshen many hours and I dont have proceedure, wonder what I'd do for more HP 400 be good, or transplant crate LS2, but will this work with what changes.
thks

I'd say valve seals, but I don't know LS1s
