Northstar engine bad design
By johnr24 on

1999 Cadillac Seville STS 4dr Sedan

Review

The Northstar engine until about 2002 had lugbolts that were too short. So it blows a headgasket climbing hills. $3500 to repair with new longer bolts. No old high mileage Northstars ,only dead ones. Engine not considered rebuildable. A Cadillac engine design mistake (30 yr Cad owner)

High Mileage on a Northstar is 90K.
