    Engine shuts off while driving

    Yep... Seeing and troubleshoot failures daily in consumer and automotive chip packages ranging from temp cycle induced fatigue cracking, to temp/humidity/bias induced corrosion..... Seen one too many perils in the Man (or person to be politically correct) or Machine, or Method to trust...

    Engine shuts off while driving

    As a “semiconductor packaging”engg, I deal with manufacturing, quality and reliability of consumer and automotive grade chips/packages. OEs like Bosch and Conti use the chips/packages from a chip company (like the ones I’ve worked for) and create the ECMs/modules. What you described is a failure...

    Fluid Replacement - Good PM Practice or Waste of $$

    Maybe a different perspective from someone who has resuscitated many barn finds.... its quite amazing how the different systems work after all these years and what does/doesn't survive the ravages of time. Engine oil is obviously bad, when I remove the drain plug there is a lot of condensation...

    Look At What Came Out Of My Catch Can

    Wait... don't install a catch can. I heard thats the only way oil is getting up there on some of these DFM engines

    Engine shuts off while driving

    Agree with that. Don’t start a parts cannon … you are dealing with a one off problem from an electrical issue that will need deep diagnostics and troubleshooting. Something the dealer should be doing since you are under warranty, I’m all for data analysis and diagnostics and parts replacement...

    Engine shuts off while driving

    Well then, back to the same dealer. "what can cause it not to start right back up. If we figure that out then we can figure out what the problem is." With all due respect, the dealer still is best equipped with GM factory manuals to troubleshoot that. If they can't fix it, GM will have to...

    Engine shuts off while driving

    If it is still under warranty, Tow it back to a different dealer and don’t leave until it’s fixed for good. As a matter of principle, (and to not give GM an excuse that you tampered) I don’t think anyone should be bothered and take matters into their own hands with a vehicle under factory...

    6.2L - Debris Found in Engine Oil

    Keep an eye on oil consumption and please report. You can pull out the dipstick in your usual parked position first thing in the morning before start and just keep doing it every 500-1000 miles, should know how much oil you are using. Plastic debris ? Maybe timing chain guide?

    Look At What Came Out Of My Catch Can

    Ya that quantity is what the old big block in my truck would accumulate in 300 miles, with my oil burning progressively getting worse I was worried about blowby on this tired engine and I ran a catch can until last month, but I'd only get ~0.5oz (about what is pictured there) but magically...

    Engine out 228k high mileage maintenance 5.3 L59 LS Swap

    I can think of the oil pan/pickup, but then it depends how easy it is to drop the oil pan later in your Jeep. If it is easy, you can just install the engine/trans in for now, if it's not possible without lifting the engine (As it was with a lot of makes/models back then because of riveted...

    Yukon Engine Failure - Buyback?

    They are both rated for about the same HP/Torque and the 6.6L does it with the common man's fuel. I'd also guess a HD truck engine like 6.6L really makes more torque on the lower end (and thus horsepower numbers are skewed lower) And "LS" is just my term for the Chevy engine that was so...

    Would be great to “LS swap” these engines ASAP ;)
