hemsteadc Posted August 12, 2018 Report Share Posted August 12, 2018 Seems to be the summer of problems for me. My 2008 FL SC Cummins 8.3L started whining and whistling on hard acceleration today. Assume it's the turbo, which was new 5 years ago. Is it shop time.. again? Link to comment Share on other sites More sharing options...
DieselHP Posted August 12, 2018 Report Share Posted August 12, 2018 I would check for a hole in a hose or loose hose clamp. If you didn’t have a large power loss it might just be a pin hole in a hose. Link to comment Share on other sites More sharing options...
hemsteadc Posted August 12, 2018 Author Report Share Posted August 12, 2018 I'll check again.. I did look for loose clamps, nothing yet. Isn't 5 years too soon for replacement of such an expensive item? Link to comment Share on other sites More sharing options...
Alie&Jim's Carrilite Posted August 13, 2018 Report Share Posted August 13, 2018 Loose clamp or a cracked or pin holed boot is the likely culprit. Look at the intercooler boots as well.

DieselHP Posted August 13, 2018 Report Share Posted August 13, 2018 If you have someone you trust power brakeing and spooling the turbo should help find it Link to comment Share on other sites More sharing options...
DesertMiner Posted August 13, 2018 Report Share Posted August 13, 2018 Check the gasket area where the turbo connects to the exhaust manifold for appearance of soot or oil. Next check the exhaust manifold gasket for leaks Link to comment Share on other sites More sharing options...
hemsteadc Posted August 13, 2018 Author Report Share Posted August 13, 2018 I'll check what I can, but some of these things I may have to leave to a shop. thanks Link to comment Share on other sites More sharing options...
hemsteadc Posted August 20, 2018 Author Report Share Posted August 20, 2018 It's my exhaust manifold gasket. Cheaper than a turbo. Looks like Desert wins. Link to comment Share on other sites More sharing options...
dosbeagles Posted August 22, 2018 Report Share Posted August 22, 2018 Great you caught it when you did. 2015 we had both the exhaust manifold gasket and turbo replaced at the same time. It was cheaper to replace the exhaust gasket when the engine was already taken apart to do the turbo. Had it done in Duluth MN camped outside of Cummins I Power for almost a week. Definitely no fun. When we were there say another rig that did not pay attention to the whine and was towed in. Their turbo exploded. I for once was grateful for my repair bill over theirs.

hemsteadc Posted September 5, 2018 Author Report Share Posted September 5, 2018 Man, I am being deluged with problems. Picked it up 2 weeks ago from getting manifold gasket replaced. Drove home fine. Let it sit for 2 weeks. Started it up yesterday, ran a bit rough, Check Engine light on. Engine smoothed out, Drove it a few miles, check engine light off. Drove another hour or so without incident. Started up this morning, shaking like hell, running very rough, check engine on. Drove to closest Freightliner dealer, barely made it. It's there now. Any guesses? Good thing I'm made of money, and not out in the dingles with this bucket of bolts. Just got the call : Injectors 3 and 4 are open. Whatever that means!

ms60ocb Posted September 7, 2018 Report Share Posted September 7, 2018 Gee sounds like a few problems I have had. Having been to the wrong dealer. Had EGR cooler plugged and replaced. Left the dealer with an A/C plumbing problem. Had a wet front wheel bearing leak. No problem found, re-overfilled.
