Keffer inc Posted October 23, 2019 Share Posted October 23, 2019 (edited) So I broke a bolt off the manifold bolt that holds the egr onto the manifold. I couldn't get it out so I'm letting the dealership handle the replacement because I think the actual bolts holding it to the cylinder head would likely break off too. What do you guys think? They also claim that the three piece manifold has to be replaced together because the new single piece probably won't fit into the other existing pieces. The third one (last- egr mount) manifold is the one that's screwed up. $3,600 is the quote for the exhaust manifold to the completely replaced.

Nobody454 Posted October 24, 2019 Share Posted October 24, 2019 these are the kinds of things that pushed me to sell my truck and drive for somebody else Quote Link to comment https://www.bigmacktrucks.com/topic/59508-mp8-exhaust-manifold-replacement/#findComment-434431 Share on other sites More sharing options...
Keffer inc Posted October 24, 2019 Author Share Posted October 24, 2019 I know what you mean. I may be buying a new glider Freightliner next year, but if I dont go that route, I think I'm going to learn HVAC and use this current truck as a spare income.

Already spent 8 grand on the motor this quarter, what's another 5. They better enjoy it, cause this is my last Mack.

c-mac Posted October 29, 2019 Share Posted October 29, 2019 Pull the manifold yourself, I’ve pulled many and maybe one bolt broke. On the other hand nearly every time I pull an egr valve one will break. Anyway pull the manifold, take it to a machine shop and they’ll get it out or drill and tap the hole Quote Link to comment https://www.bigmacktrucks.com/topic/59508-mp8-exhaust-manifold-replacement/#findComment-434748 Share on other sites More sharing options...
