We had two updates to a previous Piston Slap this weekend, surprisingly within two hours of each other. Let’s hear from the OP first:

Sajeev, reporting back:
You may be interested in this, if for no other reason than to add to your diagnostic toolbox; my experience certainly can’t be unique: Several comments below your post also suggested the motor mount(s) as the problem. I more recently discussed this with a professional wrench acquaintance, who also said that the mounts can be expected to go south after ~80K miles; he suggested using a padded floor jack to lift slightly on the engine during a time when I detected the “rough” idle (the oil pan on this vehicle, and maybe all Duratec engines, is waffled cast aluminum). Bingo! The vibration ceased when I did that. (Read More…)

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…)
I’m trying to wring a few more years out of my 1994 Geo Prizm, and recently the engine got louder. It’s a very low end bass like sound that makes the whole car vibrate a lot more.
The muffler and resonator are relatively new, and the noise seems localized to the front of the car. What’s odd is that the engine is the loudest when it’s idle. As soon as the RPMs go above 1500, the engine is only a little louder than it normally would be. How do I find out if the problem is the exhaust manifold, or the downpipe from the manifold to the catalytic converter? Over the summer there was a brief time when coolant was leaking and dripping down onto that downpipe and burning off. That leak issue was addressed, but that downpipe has some rusty sections on it anyway.

Nice to see you are still at it on TTAC. (Back at it?)
So my story is a 2010 Audi A4, Quattro 2.0t Premium. Red, as it should be (No, it should be brown. Duh. – SM). Just turning 60k miles. The engine is an EA888 according to Wikipedia, twin chain driven counterbalance shafts as is known to work so well on I4s. Production commenced 2008 and its in all US A4 B8s with the 2.0 gas engine. Inside oil cap the gallery is clean as can be, I keep the VW spec Mobil 1 changed with my mityvac. New plugs, NGK of correct part number, air cleaner path is fine. The rest is original unmolested.
The issue is it runs rough. Slightly, as in the car does not shake but I feel it. Worst, dead cold, running at just above idle up a slight incline. A miss. Since 25k. Goes mostly away when warm or when power is asked for. No codes. Sort of feels like a tire flat spot but it did not go away with new tires. (Read More…)
I am a longtime TTAC reader, but do not comment very often. However, I have a question that perhaps you and the B&B can help me with. I am the owner of a 2011 Kia Soul +, 14,XXX miles. Been a great vehicle so far. (Read More…)
Having planned to idle production plants for a mere ten days over the winter break, Chrysler is responding to weak sales by extending the holiday shutdown of several plants to three weeks or more. The WSJ reports that Chrysler’s Windsor and Brampton plants (minivans, 300/Charger/Challenger) will shut down starting December 21 and will idle through January 18. The Toledo plant (Jeep Wrangler) will also idle beginning on December 21, and will resume production on January 11. Chrysler is also said to be considering extended production shutdowns at its Detroit Viper factory (which is entering final production anyway) and an unspecified Ram plant. Unless December sales numbers turn out to be humdingers, this winter vacation could possibly go on even longer, as Chrysler struggles under falling sales and a 64-day supply inventory.
