BG Dynamic Egnine Cleaner. (+ pics of other damage)

Does anyone know if this is the type of solvent cleaner that can damage rubber seals and gaskets?

[dirtybrd]

I've sold the service before but don't know the results(I never looked in a motor before and after). I'm 100% sure that the results in the before and after shots of that motor weren't from running that service. Maybe if they filled the entire motor with it and let it soak for a few days.

So you're saying a freshly cleaned, desludged engine can still look like this on the inside?

Another question, how badly would this leak oil?





Local dealership claims I caused this damage when I did the timing belt. But this was seven months ago, and between that time and when they desludged my engine, not a single drop of oil. After I got my car back from them, it started leaking badly (two full quarts had to be added in three weeks). But according to them, the leak came from both camshaft seals and not this. So I was stuck with the bill for replacing the camshaft seals, and the crankshaft sprocket/housing. The timing belt shows practically no damage at all. I figured if I drove with a broken sprocket like that for more than seven months, the timing belt would be shredded

Looks to me as if one of the bolts that holds the gear had come loose, most likely install error dring the timing belt process.

That's physically not possible, you're not visualizing properly how it goes together. The four bolt heads are on the outside of the sprocket in the picture, inside the damper pulley that goes over the sprocket. Those bolts cannot impact the teeth of the sprocket. I have used a torque wrench and set it to the proper values based on the Bentley manual, when putting everything back together.

You can see the four bolts are on the outside:

It was install error, there is no way in hell the engine flush could have caused that damage.

The bolts came loose and the pully was rocking back and forth, impacted the case and cracked.

The timing belt pulley is held in place by the main bolt in the middle..The 4 bolts tighten the dampener pulley...He prob removed the 4 when he did the tb but not the one in the center as there is no need

Stay with the program, the flush is a solvent and my only question concerning that was if it could damage rubber seals. This is obviously excessive physical damage, caused by something else.

Once again, physically not possible, the toothed sprocket sits on a crankshaft flange and as noted by 20vturbo, the big center bolt was never touched, because the timing belt, once loosened can just slide off this toothed sprocket.

My only question that concerns the physical damage in the second and third photo I posted, is how much would that leak oil. I did the timing belt seven months ago. There is no way I was driving with that damage for seven months without leaking a single drop of oil and without damaging the timing belt.

I believe they damaged it when they tried to remove it..it was prob stuck and they used a pry bar to remove it and that's when they broke it...The same for the seal, there is nothing in there that would have damaged the seal, and No you can't drive with a leak like that....That sprocket would've ripped the tb apart in a few kilometers...Dealer is bullshitting

Agreed, theres no way you could for 7 months like that... dealer is bsin you, like they always do...

To drive with that for 7 months? Ha. My guess would be they used something to pry it open, and try to blame the carnage on you. Typical dealership.

I wonder if this sprocket even came from my car. Notice the damage on the inside, the part that prevents the sprocket from twisting on the crankshaft is stripped. If that happened during the tb install, the timing would be out of whack in the very best case, or most probably, it would have arranged an unpleasant meeting between pistons and valves. How the hell did they manage to do that

[Papachristou]

Damage was caused during removal. The car wouldn't run like that

[vdubstreets]

that belt would of definitely shredded i guess its time to call AoA.

I second that.

The damage you see was most likely caused by excessive force trying to remove that crank timing belt pulley.








This is damage done to the serpentine belt pulley when those four allen bolts loosen up. 2,000miles worth of driving on a loose pulley. I saw no damage to my crank timing belt pulley or the four threaded holes in that pulley.

dude, fight that shit, effin stealers...they tried to eff me over by saying that the mobil 1 oil filters i was using sludged my motor even though i changed the oil every 3k miles...

a quick call to AoA changed all that, i hope its the same case for you...there is 100% no way that your car could run like that...in fact, i've been popping the hood to look at my crank pulley ever since i did my timing belt to ensure that it's not wobbling or has excessive play...i even reached down and felt if all four bolts were still there even though i loctited them bitches...

i don't think your car would run, let alone for 7 months if you botched the tb install...

[mxrz]

I started with the service manager, he promised he's going to review the whole case... Next step would be AoA or the Canadian equivalent I guess. I'll give him a week.

[dirtybrd]

The pulley and cover looks like someone wedged a prybar between them to remove the pulley.

[Dopefish]

Wow, that is some serious damage! I'd agree that appears to be damage from some sort of excessive use of a prying tool. I hope you get it worked out with the dealer and if not, Audi of America. Just remember to keep a cool head about it and continue to escalate things through the proper venues, getting upset and rash will only aid their argument.
