Early year Northstars had a lot of oil / seal issues. Up and away with a new name and logo !
I had an Olds Aurora V8 that I think was the same basic engine. Unique Great performance, but it too liked a little oil.
Totally agree with Kim Foster. As a owner of four Cadillac Allante's I have seen the issue described. Re-Sale of NorthStar engine vehicles has been hurt. New day is needed.
NORTHSTAR for the GREAT WHITE NORTH
The Northstar engine did have the head gasket issue caused by stretching headbolts. So that did givee that name a negitive reputation. Time to move on to the next generation. Hopefully all those prior issues have been resolved. It's a new day!
