Sajeev,

I’ve got a 2002 Cadillac Seville with the infamous Northstar engine. I bought it nine years ago and at the time it was four years old and had 30K on the clock. Before I even ask, I’m sure you can already guess what happened. At 149,000 miles the head gasket issue has reared its ugly head. For those readers who are unfamiliar, the repair requires the engine and cradle to be dropped, stripped down, and re-studded with twenty new holes. As opposed to timeserts, this fix is usually permanent.

I just bought a mint condition, dealer-maintained 1990 Cressida. I am aware of the head bolt torque issue on the 6 cylinder engine. The car shows no sign of head gasket issues. My question: should I have my dealer simply re-torque the head bolts? Their tech (30-year’s experience) says he’s done this on many cars with no issues. Your thoughts?
