You don't need that tool for the rear main. I install seal into the cover loosely, install cover with bolts then press it on by hand then torque the bolts down. No leaks and I'm pushing close to 800whp in my 91 z28

it's fun and games until you do a 30min track session and a misaligned seal goes BY BY. 1/4 mile pulls and burnouts don't put an engine under nearly as much stress as running all-out for 30min.

he was pretty sure with the way his pvc system was set up that it was causing to much crankcase pressure and it blew his seal out.

junkyard LS1 with questionable miles. my PCV routing was wrong so I think crankcase pressure was getting way to high.

It's going to leak again. The problem is the trust surface on ls engines is weak and this is what causes this leak

never heard a soul ever mention the crank thrust spec for causing a leak

@@3rdGenGuy Never heard of it either, and I've been doing this for forty years. The thrust bearing would almost have to be missing for the crank to walk that far. I've seen Windsor Fords and big block Chrysler's eat thrust bearings and journals.

why risk a job that takes 4-6 hours to do? tool guarantees the main seal will last and not leak.

I talked to an engine builder that probably builds 10x LS 427s a week, and he said that tool is ABSOLUTKLY necessary. although the OEM tool is steel.

@@notchbackgta torquing the rear cover can cause the plate to move off center. Torquing the cover before the two pan bolts can cause it to be off center. The alignment tool is a must!
