E Brake Question

[Cobra]

I know there has been alot of info on this subject but... . Last Friday May 11, 01 I had a Jacobs Exhaust brake installed on my 01 RAM 2500. It was installed by the dealer and I love it. Now my question. Almost every moring I stop for coffee at the local coffee shop. The new diesel is a topic of conversation quite often and after the brake install I was excited to tell the guys about it. This morning one of the guys told me that trapping the exhaust will undoubtedly cause exhaust valve problems. Is there any truth to that? Thanks for the replies.

The only time that the exhaust is PARTIALLY trapped is when you are in a defueled condition or at idle. I imagine the gas temperature in the neighborhood of those valves gets a lot higher when the engine is working.

No, its not a problem, in fact the ISB has stronger valve springs so you CAN use these brakes!

The only problem I see is when you pull into a stop, with the brake on, the turbo is running about 400-500 deg, you have to turn it off, and wait a couple minutes to get your turbo temp down, or shut it off BEFORE you get to your stop and it will already be cool.

One advantage is when you are pulling a long hill, your valve temps get pretty high, now let off the fuel, and start down the other side and without an exhaust brake, the valve temps drop real fast, with the brake on, they cool off slower which helps prevent warping (information from the BD advertisment I think)

Oh yeah? Was this guy a Cummins mechanic or engineer? Don't tell me he drove a Chebby too! #ad

Thanks for the replies. I didn't think there would be a problem becuase there are many people using them and it is a Mopar piece which is now warranted for the same time as the truck and the engine. 3 years/36,000 truck and 5 years 100,000 isb.

thanks loads, it always feels better when others vocalize what you believe to be correct.
