The exhaust...It sounds like there is nothing wrong. The exhaust brakes tend to stick with those applications. If they pulled the inner air filter it may be because they didn't want to put a new one in $$$. It's better with both but one is still sufficient. I would hook up the exhaust brake and see how it works. There may be a fault with it and the previous owner didn't want to fix it. They don't make a huge difference in braking since they're not an engine brake.Anonymoushttps://www.blogger.com/profile/01517188475250181833noreply@blogger.comtag:blogger.com,1999:blog-18449820.post-28021075993365354022010-09-17T17:47:54.678-07:002010-09-17T17:47:54.678-07:00I just bought a 3116 in a 91 topkick with only 40K...I just bought a 3116 in a 91 topkick with only 40K. I thought it strange that the BD exhaust brake was disconnected, but it runs fine. It was when I started my service I discovered what I think is why the brake is not working. Also the inner air filter was pulled. Bought new inner/out air and changed fuel filters. Notice a little oil in the exhaust on first start up with new filters. Suspect the exhaust brake blew the turbo, and they pulled the inner and sold her. No smoke and oil consumption is not high,.<br />BTW you can almost eat off this engine, the truck is CLEAN. THe EXH brake is new.<br /><br />Rebuild turbo? Adjust valves?<br /><br />what else before I hook up exhaust brake?<br />WayneWaynehttps://www.blogger.com/profile/08611956488753772146noreply@blogger.com
