Good diesel mechanic needed for diagnostic

[opie011]

I think my truck is having some bad blowby and I also lost quite a bit of oil while driving the other day. I washed and cleaned the motor up and the leak doesn't seem as bad but difinetly a leak on the driver side of the block. Anyway, I need someone to pull the head and diagnose the problem so I can make my next move.

BTW: 2003 Dodge Cummins with 192xxx on the clock.

I am stripping to a bare block and building a 2010 15 liter cummins as we speak... But i have never been into a cummins 5.9 newer than a 98 so no 24 valve. I am know i can handle it if you need me too. but hopefully someone with more 5.9 exp will chime in. give us an idea of where it is leaking from if you can sometimes a leak will just pop up and the only way to truly condem blowby bieng the issue is to have it run on a dyno and see if the blowby is out of spec. On the big boys 12 inhg is the max on a cummins. which is a metric F ton compared to a caterpillar.

UMMMM 1850 ft lbs of torque might be a bit much but we can give it a hell of a run.

Why would you pull the head to diagnosis an oil leak or am I missing something?

RIF. You think you have blow by. What you need is a compression and leak down. Head doesn't need to come off yet.

True I don't need the head pulled right away I was just thinking I would like to see how the pistons/walls and rings looked. I have a little rough idle and and when I did the blowby "test", idle with the oil cap off, I saw a little bit of bluish gray smoke almost like steam coming from the fill hole....not too bad as I've seen worse.

I thought diesel mechanics just replaced clutches and brakes.

Yes if you are a fleet mechanic like me and trouble shooting requires the parts shotgun!

Here's some pics of the oil splash. I had grease monkey do an oil change last Wednesday and didn't drive it Thursday. Friday I drove up to Greely and noticed oil everywhere. I know grease monkey but I get my oil changed once a month from all my driving and I don't want the oil just chillin in my garage. I do all other maintainance. Anyway I thought they overfilled it but there's oil in front of the crankcase vent tube so kinda ruled that out. Also, I thought the gear case/housing or maybe the front crank seal but there's no oil on the front of the block. It seem to be coming out the driver side of the block. Thought maybe tappet cover gasket but I can't find that so maybe the CR blocks don't have one?? I have been looking for a reason to get a new truck, maybe this is it.

K i am done going to bed
And I agree with tmlead lets get the leak diaged before we yank a head


Unless you wanna fire ring for the plans of building it up
