Background first:have had it since new very little work done on it except it had the bed plate oil leak when new(2003) and dealer fixed. Has 118000miles on it with regular maintainance. Now I am going on vacation in 2weeks and pulling a 30ft travel trailer(10000lbs.) Today I get home and notice fluid on the transmission house bottom,the fuel tank on back. Not super thick but looks like raditor fluid. If you lay on the ground and look up on the drivers side you see the little stream coming from up above the exhaust manifold then I can't see from there.I know the radiator reservoir is up above that now I looked from up top and radiator cap had no leakage or spewing nor was it low on fluid. The driveway had some small spots. This had to of just started today because I was at someones house earlier and there was no spots in the driveway. Drove home(30miles) and noticed the spots and underbelly lightly coated on back to the rear axle. I don't think it is a hose(top or bottom radiator) because they are only about 1yr. old. I hope this is not a major problem or alot of money to fix. Help does this mean the motor is going kapot. PLEASE HELP.

 

Anyone have any ideas,please need help before I go to dealer and get screwed.

 

First off, are you sure it's coolant that you see leaking? Are you sure it's not engine oil? Since you mention the bedplate as being your only repair to engine so far, it would be pretty safe to say it's your ICP sensor that is leaking oil through it, by what you describe. If this is the case, the repair is not terribly expensive.

 

Is the ICP sensor located anywhere on the driverside manifold? The fluid looks clearer thenoil and when you take a kleenex and blot the spot in the driveway it looks more like rad fluid.

 

If you are sure it's engine coolant, it can either be leaking from the underside of the coolant degas bottle (age-cracked) or the EGR cooler hose, if it still has the original orange coloured hose.

 

Thanks tomorrow after work I will drop it off at the dealer, will it hurt to drive it?

 

It was oil, alot more today, dealer can't get to it til monday so I will drive it just to work tomorrow and monday to dealer. What is the cost of replacing the ICP sensor or the bed plate replacement?

 

Found out today that it is the main bearing seal on back side of motor dealer says the tranny has to be dropped to get to it and will take 8hrs and $1000 parts and labor does this sound about right for the charge?

 

For what it's worth, rear main seals very rarely leak on any 6.0L I've ever wrenched on. You stated you already had the bedplate resealed at one point, which would be the biggest major undertaking to repair. Like I already stated, ICP sensors are the most common oil leak source on any 2003 I've ever wrenched on. Given that the leak you describe, appears to originate from above, only makes it less likely that it would be the rear main seal. If I were you, I would request to have them put the vehicle up in the air for you to see for yourself first, before you give them the green light to go ahead with the repair.

 

Had the ICP sensor leak fixed and the rear main seal fixed and now have oil (a small amount) after driving maybe 20miles coming from the little seam or crack on the bottom of the transmission. There are two bolts that are on the trans. and a black rubber cap above it on the trans. that covers and can pop out. This is hard to describe but the oil comes from the seam in the tranny and is not trans fluid or coming form above. Anyone have any ideas.

 

The way it sounds all 6.0 leak to some degree?

 

Any ideas!!!!!!!!

 

if I just paid 1800 for a oil leak reapir I would carry it back and ask them for ideas.

 

So, they replaced ANOTHER ICP sensor and they replaced the rear main seal, this go around if I understood correctly?

 

thats what Im calling.
