: Broken dmax with banks exhaust brake

Just had a quick look into the latest Truck Trend.Very unlucky guy broke his dmax (broken valves no. 7 and 8). GM refuses to pay for the repair (22.000 $ damage) because of the installed Banks exhaust brake. According to Banks their system never exceeds the 55 psi limit given to them by the manufacturer - so they won't pay either...the case will go to the courts....
Hope the guy will get a free repair for his dmax.
Does anyone use any kind of exhaust braking system on the dmax?

Max Power 08-16-2004, 11:51 PM $22,000?? Really? That's a F^%& load of money.
What does 22.000 mean? $2,200? Or $22,000Edited by: Max Power
tpitt 08-17-2004, 12:02 AM From what I've read that isn't the only one Banks has destroyed. I use nothinq but BD-Power exhaust brakes. tpitt
mahalkita 08-17-2004, 12:14 AM MP, the repair (exchange of whole engine!) costs twenty two thousand dollars (22000) according to the magazine. The damage is so big that a repair is basically impossible (useless) and the experts recommended to change the complete engine.
No wonder why a new truck is sooo expensive.

McRat 08-17-2004, 12:35 AM $22k? Is that Canadian? ($200 US)
Seriously, how many motors is he getting?
mahalkita 08-17-2004, 12:40 AM Thats U.S. Dollars and probably includes the labor etc. Looks like an expensive fix to me too!
BuckeyeQuicky 08-17-2004, 01:17 AM I just read the article to, whats so funny about this is, GM is saying that the Duramax is not designed to take the pressure build up that a Jake brake produces, but whats even more funny is the fact that GM installs Jake brakes on their heaver trucks that have the Duramax engines in them, so who's bull 5hitting who, and I'm also wondering why the guys being quoted $22000. for engine repairs when a brand new engine in a crate should only cost around $6000.http://www.dieselplace.com/forum/smileys/Confused.gif , but like one of the posters mentioned above, this isn't the first time Bank's installed engine brakes have caused people trouble, because last year on a RV web site, there were a couple Motor home owners who went threw the same thing when they installed Bank's engine brakes, and Bank's more or less told them to bad what do you want us to do about it.

Idle_Chatter 08-17-2004, 06:15 AM Nothin from nothin, Buckeyequickly - but a "Jake Brake" is not an exhaust brake. An exhaust brake is just a flapper that puts backpressure on the exhaust and is neither an engine brake nor a Jake Brake. A Jake Brake (comes from the original supplier - Jacobs) is an engine brake that opens and holds open the exhaust valves on the engine. The biggest difference is that the exhaust brake is very simple and quiet - blocking the exhaust, while the Jake Brake bypasses all compression to the exhaust making that classic BRRRRRAP! That's why there are all those "NO ENGINE BRAKING" or "NO JAKE BRAKE" roadsigns at the entrance to small towns - noise.http://www.dieselplace.com/forum/smileys/Approve.gif The exhaust brake is a very simplified system and has shown to be damaging to more than one truck.http://www.dieselplace.com/forum/smileys/Dead.gif

I've installed probably around 50 BD-Power exhaust brakes, on all 3 brand trucks. Please explain the damage from these brakes. I've yet to encounter any and none of the other BD installers I know have either. I know Banks have had problems with theirs. They entered a market of which they don't have a clue. tpitt

The last time I checked, a DMax (here in Canada, at least) is a $20,000 engine, not a $6,000 one. You will get around $5,000 for the old core, but I was very hesitant about buying a DMax for that reason.

Idle_Chatter 08-22-2004, 11:22 PM Good to hear that the BD is a safe alternative, tpitt. I have heard of at least four major engine damage cases with exhaust brakes - not sure if they were all Banks, but know at least a couple were. Not being a hauler or heavy towing owner, I've been very happy with the Allison grade braking. I know that it isn't enough for really heavy and steep stuff, but I personally don't feel that choking the exhaust can be anything but stressful to the exhaust valves and engine in addition to holding a lot of heat.
