Yep, Chris is a "loner"


He's the only "documented" CT member to have over 100k miles on an A5 5.7 car, without having a TC failure.


And he hasn't babied it either!

randycat99 Is that for real?!? You should ABSOLUTELY acquire your chain guide parts after the procedure. We need to see what a 131k part looks like that was rescued intact (whether you have mds enabled or not). Are you hearing what I am telling you???

LONE WOLF I am glad this issue is in the past for me. 35k miles since (done at 75k) and she runs awesome, especially since I did the 392 cam swap at the same time.

72/340 I'm at 34k since the TC failure and rebuild. At 8k since the recall was done. Runs like a champ.
On a side note....I have messed with all the Predator tunes and right now am happiest with stock tune, 89 gas, MDS off, and 15% throttle boost.

19johned53 12k miles since my P01. Zero issues, runs as good as ever, and yes, I run it hard.

Because you asked, an update on our 2010. Coming up on 7k miles on the new block and heads, almost 9k since TC failure.

Failed on the highway 11/21/2013, at 54,153 miles. Two months before that had contacted dealer to describe a highway speed problem that felt like the engine losing power for a split second at a time. Had heard about TC failures at that point, and asked specifically about preventive maintenance. Was told "timing chains don't fail on 5.7L HEMIs... never seen it". They applied a firmware fix (TSB #18-021-13 ) regarding "Performance Derate Above 55 MPH Immediately After Start-Up When Accelerating At Wide Open Throttle".

At time of failure 80% or more of driving was highway (Wife's car, she was doing almost daily 160 mile round trips at the time). Out of town dealership that received the car on a flatbed said, "Can't be the timing chain, they never fail"... and 2 days later called us saying TC broke. Ended up replacing the guide, tensioner, chain, 2 intake valves, 2 exhaust valves, 1 intake pushrod, 1 exhaust pushrod, oil control solenoid, and brake booster check valve. Received the car 11/27/2013.

Subsequently a regional Chrysler service advisor inspected the car (borescoped) and declared it "all good", but did approve new lifters, due to new lifter noise that didn't exist before the "repairs". Hometown dealership went to perform the lifter replacement on 2/7/2014 at 55,967 miles, and upon opening the engine found multiple scored cylinders and crossthreaded intake bolts and valves not seated into the head. Short block, heads and lifters all replaced. Received the car on 2/28/2014.

Since then, she doesn't make those trips anymore, perhaps once a month... we're just now coming up on 63k miles, 80% or more local driving. My wife drives it like she stole it - always has. Same way she drove her '93 GT 5.0 when we met. She swears it doesn't have as much pep as it did before the block/heads change, and that engine braking is more pronounced than it used to be, but other than that it has been problem free. I don't drive it enough to be a good gauge of comparative performance before/after. MDS engagement was never very noticeable before, not any more so now. First two oil changes since block was replaced were with conventional (1000 miles, 3000 miles). Last change was synthetic.

fxef79 It is neither a "Recall", nor a TSB. It is a "customer satisfaction" action.

You should have received a paper notification in the mail, however, just like you would with a recall.

crow It is a recall, not a TSB.
