Piston Slap: Northstar Mills, Northstar Bills…

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.

Piston Slap: Of Head Bolts, Bad-Ass Sedans…

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?

  • Ronnie Schreiber From where is all that electricity needed to power an EV transportation system going to come? Ironically, the only EV evangelist that I know of who even mentions the fragile nature of our electrical grid is Elon Musk. None of the politicians pushing EVs go anywhere near it, well, unless they are advocating for unreliable renewables like wind and solar.
  • FreedMike I just don’t see the market here - I think about 1.2% of Jeep drivers are going to be sold on the fuel cost savings here. And the fuel cost savings are pretty minimal, per the EPA: https://www.fueleconomy.gov/feg/PowerSearch.do?action=noform&path=1&year1=2022&year2=2022&make=Jeep&baseModel=Wrangler&srchtyp=ymm&pageno=1&rowLimit=50Annual fuel costs for this vehicle are $2200 and $2750 for the equivalent base turbo-four model. I don’t get it.
  • FreedMike How about the “Aztek” package? Wait, this car already has that…Said it before and I’ll say it again: they need to restyle the hind end on this car, stat.
  • Johnster "Vale" is the [s]cheap[/s] lower-priced performance version with black trim and stiff suspension."Mist" is the "DeLuxe" version with a bit more chrome and trim. (Sort of like the "Decor Package" option.)"Magentic" is the full-on Brougham treatment (in its current state) with more chrome trim than the "Mist" and all sorts of gimmicky electronic features inside. (Sadly, it will not include simulated landau irons or a vinyl covered roof, even as an option.)"Aurora" is the Oldsmobile of Cadillacs (sort of like the old Cadillac Calais). No, that's not right. It's the top-of-the-line model, sort of a "Grand Touring" version, with not as much chrome as the "Magentic" but all of the gimmicky electronic features and a stiffer suspension.
  • Drew8MR Why can't CARB leave hobbyists alone? Maybe lay off the low hanging fruit and go after the gross polluters. Bring back the rolling exemption.
