Sajeev,

Your post of 2 Mar 2011 was a great explanation regarding the cause of the “T” joint oil leak I’ve been experiencing. No one on any of the normal Ford sites has been able to pinpoint the problem, so I thank you for the information. (I’d discovered the source, but didn’t know the cause/fix until your post.) TTAC is now on my Favorites list! (Read More…)

Sajeev,

I have a piston slap question for a friend at work. She drives an ’11 Mazda CX-7 2.3. For over a year she has had an issue with fuel in the oil. Enough that the oil level has been as much as 1″ above the full mark on the dipstick as a result (oil level was checked after service, and frequently between services). This is noticed within weeks of service/oil change. (Read More…)

2001 Tiburon (yep, this one again): Gassing up clicks like it’s full, even after only a dollar, then keeps clicking. Tank is at an 8th when fueling and yes, i’ve made sure it’s not the nozzle (and does it no matter where I go). (Read More…)

America may be the world’s up-and-c0ming natural gas producer, but if you have a car powered by CNG, good luck finding a station. CNG terminals are thin on the ground in certain parts of the country, and half of them are closed to the public.

The Economist has put together the above chart showing global gas prices as of February 2012, as well as how fast they’ve risen in the past 12 months. Even with gas approaching $4 overall, we’re not doing too badly compared to the rest of the world.

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…)

Know what to do next time you see a higher price at the pump? Don’t buy gas on May 15? How lame. Learn from the folks in India. According to the BBC, India’s opposition parties have called a general strike against fuel price rises, and  “normal life has been disrupted in many parts of India.” (Read More…)

The conversion of vegetables into car fuel continues. In Japan, the Agriculture Ministry teams up with Toyota, Denso, the Chuo university in Tokyo, the Kyoto university and others with the goal of producing fuel from produce. From algae, to be exact. Are algae food? In certain parts of the world, they are. As I’m in Tokyo, dried algae are in the snack tray next to the computer, and they begin to infest the keyboard. The green stuff that wraps sushi is dried and pressed algae. (Read More…)
