How often does a stock LS1 oil pump fail?
I hate to close this one. Was hoping the roasts would pile up and make me smile. Oh well…
Definitely want to edit or delete that one!
FWIW - 😆 I posted in this thread 19 years ago! Time to update.
It was a bit worry some back in the day (1999 -2001) as several new/nearly new/low mileage LS1's had oil pump issues.
1) My 99 T/A got a Katech ported LS6 oil pump in 2002 when the car got heads & cam as insurance.
2) One of my friends bought a 2000 FireHawk with ~21,000 miles from Carmax in ~2001 and the LS1 oil pump was still enough of a concern he got an extended warranty. His car has 93,000 miles now and the original oil pump. He remarked that extended warranty I'd suggested proved a waste of money. I pointed out he'd had piece of mind plus a couple of extra years with a warranty.
