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. (Read More…)

I need some advice – I am struggling with a decision on what to do with our daily driver. It’s a 2002 Infiniti I35. 140,000 largely trouble-free, easy, no fuss miles. It does everything we want, has some creature comforts, is in very good, clean condition. (Read More…)

1988 Dodge Shadow

She done me wrong. I was beside myself with grief, anger and stress. Things had been going so well when, suddenly, a former lover waltzed back into her life and caused her to leave me in the lurch. Part of me wanted to win her back, to show her I was better than him. The other, darker part of me wanted to find that guy and kick his ass. It was a terrible time, and to make matters even worse, by faithful Dodge Shadow wasn’t running right.

My TDI in Japan

The engine quit with a sudden un-dramatic snap, and the little Golf TDI began to slough off speed. Reflexively, I bumped the gearshift lever into neutral, flicked on my signal and began moving towards the left edge of the expressway. My exit was less than a mile away and, rather than stop alongside the highway, I used my momentum to coast up the off-ramp and over the small knoll that stood between the expressway and the toll plaza. I stopped there, on the back side of the hill where the road widened on the approach to the toll booths, to avoid blocking traffic and dug out my cell phone to call for a tow truck. I didn’t know it then, but it was the last time that I would ever sit behind the wheel of the little car, never mind the fact that it would follow me again around half of the globe. (Read More…)

Sajeev,
Thanks for the post. At the end of March, I bit the bullet and replaced the right cylinder head with a rebuilt one from Advance Auto. With my on line discount and a new head gasket, the total parts cost was under $200 plus a day’s labor. (Read More…)

Dear Sajeev,

As a fellow Panther owner, I am seeking advice on the disposition of another Ford product. My 24 year old son just bought a new to him car and returned my 2000 Ford Taurus with the 3L Vulcan overhead valve engine to me. At 206K it runs great, but has one issue. Combustion gases are entering the cooling system and periodically venting through the coolant de-gassing tank. (Read More…)

Hello Sajeev,

You’ve helped me greatly in the past, and I once again turn to you for your knowledge of used cars and reliability.

To refresh your memory, I drive a 2002 Chevy Cavalier Z24. It’s a 5-Speed Manual, with the 2.4L Quad 4 motor in it, not the lifeless 2.2. I’m about to hit 145k and I’ve got a few concerns about the car and what I should exactly do with it. (Read More…)

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? (Read More…)

Hello Sajeev,

I just bought a 2000 Saturn LW1 6 weeks ago.  It has a L4 2.2 Liter engine with 200,000 miles on it.  After 3 weeks out of the country I came back and started it up.  Was a little rough then smoothed out.  I just changed parking spots.  Did this one more time.  The third time starting it up it would not fire.  No strange noises, just no running engine.  I suspected bad ignition coil.  I had just changed the spark plugs before my trip and they had about 50 miles on them.  Ignition coil was fine at all four points using a ignition tester.  I even put new plugs in again.  Fuel rail has the specified 60 PSI.  Theorizing that may the fuel injectors were shut down i tried starter spray in the air intake.  The motor will not fire.  A compression test with a gauge picked up at advance gave me less than 10 PSI on the two outer cylinders and about 24 on the two inner.  The Haynes manual is very unhelpful and only states for compression specs. that the lowest compression cylinder value should be no less that 70% of the highest compression cylinder value.

I read on-line (http://www.saturnfans.com/forum/showthread.php?p=1781795)  the same but that no cylinder should be less than 100 PSI.  While cranking the engine there was some light smoke visible behind the engine above the exhaust manifold, but unable to determine the source.

My question is: are you aware of catastrophic head gasket failures on these engines?  I am surprised that the engine will not fire at all even if the head gasket does have a problem.  I have removed the valve cover and see that the timing chain is still there and working.

When I changed the plugs last month I applied anti-seize thread sealant to the plugs as instructed in the manual.  I am now having wild imaginings that the anti-seize thread sealant got into the cylinders and impregnated the gasket and is somehow responsible for this catastrophic failure.   I am going to tear into the engine tomorrow and try to replace the head gasket, because i need to get this car running again ASAP.  I am being hopeful and unrealistically optimistic that I cold get some input/ thoughts from you before morning when I start this laborious task…

Ideas? (Read More…)
