Stretched out Posted January 1, 2014 Share Posted January 1, 2014 Started in on restoration of my 91 R yesterday. Got charge air cooler and exhaust unhooked from turbo and found oil on both sides of turbo. Going to take manifold off today to see what it looks like. Have no water in oil and no oil in water. So I don't believe it is the head. Do you guys have any suggestions, thanks Quote Link to comment Share on other sites More sharing options...
rsb502 Posted January 1, 2014 Share Posted January 1, 2014 Both sides meaning what, there are 4 inlet/ outlets, intake air, charge air, exhaust inlet, exhaust outlet.

Challenger Posted January 1, 2014 Share Posted January 1, 2014 Sounds like your turbo is passing oil. Grab the propeller nut and check for up and down play. Quote Link to comment Share on other sites More sharing options...
j_martell Posted January 1, 2014 Share Posted January 1, 2014 Sounds like your turbo is passing oil. Grab the propeller nut and check for up and down play. What he said,sounds to me like spun turbo bearings..... Quote Lack of planning on your part does not constitute an emergency on my part....

gearhead204 Posted January 2, 2014 Share Posted January 2, 2014 are the exh. ports wet where the exh. manifold meets head? if not change the hair dryer. if so run truck under a load and reinspect eng. may have been idled too long either way oil in charge air piping = new turbo Quote Link to comment Share on other sites More sharing options...

Stretched out Posted January 3, 2014 Author Share Posted January 3, 2014 Got the turbo and manifold off tonite. There is oil in exhaust ports. Thinking possibly valve guides? Do you guys have more ideas Quote Link to comment Share on other sites More sharing options...

farmer52 Posted January 3, 2014 Share Posted January 3, 2014 Any oil in the intake side? Quote Ken PRR Country and Charter member of the "Mack Pack" Link to comment Share on other sites More sharing options...
gearhead204 Posted January 4, 2014 Share Posted January 4, 2014 the turbo can still be tight and push oil like glenn said plugged air filter will cause this .if you don't know the history of this truck I'd reassemble with old parts for now change air filter clean turbo and manifold and run truck under load and reinspect also check draft tube for excessive blow by. (You could change turbo if you have a good one before test running, seal maybe too damaged on old turbo to reseal) I'd hate to see ya rebuild the heads only to find out you needed a in frame Quote Link to comment Share on other sites More sharing options...
Stretched out Posted January 4, 2014 Author Share Posted January 4, 2014 No oil on air intake side and air filter seems to be clean. I just bought the truck so I have no idea of the history of it. Pulled pan and appears to have bearing rolled in as they are stamped but that's all I really know about it. I thought about going ahead and pulling head off and doing inframe. Already have charge air cooler and radiator out of the truck. Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted January 4, 2014 Share Posted January 4, 2014 well in frame and turbo plus dual cleaners should fix it. be sure to pressure check the intercooler while its out! Quote Link to comment Share on other sites More sharing options...
Stretched out Posted January 6, 2014 Author Share Posted January 6, 2014 I'm sending the inter cooler off as it has few spot where fins are shoved in. Likely will need replaced. Where is my best bet to get an in frame kit and reman heads. Waiting for price from Mack but didn't know if there is better place or not. Also I read on here before that an e9 turbo will work on an e6. Will it also work for e7 or is it that even recommended. Not worried about getting more power out of it. But figured I would check into it if it doable while it's all tore apart Quote Link to comment Share on other sites More sharing options...
Stretched out Posted January 6, 2014 Author Share Posted January 6, 2014 The draft tube on top is wet as well if that tells you anything also Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted January 6, 2014 Share Posted January 6, 2014 the wet draft tube is normal if you can use it for a leaf blower that's not normal.... seen a few that would clean shop floor! you could check pai or ipd for kit prices don't know who your local dealer is should be able to find on line Quote Link to comment Share on other sites More sharing options...
Stretched out Posted January 6, 2014 Author Share Posted January 6, 2014 Two diff Mack dealers around here. One $5700, one was was 7k for inframe kit and reman heads. Waiting on a call back for pai and ipd prices. Do you know if the e9 turbo will work on the e7 Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted January 7, 2014 Share Posted January 7, 2014 don't know on turbo but I know you cant buy a e9 turbo from mack, you could probably sell a good e9 turbo and get a good one for the little guy Quote Link to comment Share on other sites More sharing options...
Stretched out Posted January 7, 2014 Author Share Posted January 7, 2014 I do understand that. I will probably just go with original turbo Quote Link to comment Share on other sites More sharing options...
