i have a question my 6.0 is leaking coolant. as soon as i pour it in is is running out on the rear passenger side of the motor and has water in the oil. any thoughts as to whats wrong. sorry ahead of time know nothing bout this motor other than what ive read in blogs and forums

 

can you pinpoint where the water is coming from? top of motor or side of motor? if you have water in oil it is either a ruptured oil cooler or blown head gasket. How is it running and are there any mods to the truck

 

Bob, have you ever really seen oil and coolant mix cause of the headgaskets? I have not yet, I have seen it from cracked heads though. Oil cooler would be most common though, I'd venture to guess.

Yeah could you get some pictures or something, I'm not sure where it would be coming from back there... only thing I can think of is EGR cooler connections leaking and it's just making it's way over there... or the coolant hose coming off of the heater core on that side.

Are you POSITIVE there is water/coolant mixing? Have you had an oil analysis done?

 

cold air intake and 4 in mbrp from turbo back only after market i have. everything is stock. it looks like it is coming from the back of the motor. it hasnt ran in months. last it ran i lost power going up a hill and my temp gauge spiked. pulled over and limped it home

its milky on the oil cap

 

Oil cooler me thinks

 

any suggestions for upgrades?

 

milky oil cap doesen't mean anything, could be just condensation, you would have to drain the oil to be sure. sure sounds like oil cooler, no i haven't seen water oil mix because of head gasket but it is possible.

 

1. No need to apologize, we weren't experts when we started. Well, MDUB might have been.
2. Mine was slowly leaking out the passenger side for a few years, when it finally got to leaving more that a puddle over night that I could track it was that I LIKE TURTLES OEM joke of a hose clamp on the EGR cooler (look next to the right side to of the intake, you'll see the little red hose). I installed an EGR cooler delete that I found on eBay for less than a buck fifty and viola, no more leaks. Granted the oil part is a little different.
3. Bob is right, I helped a guy change a head gasket on a 300 six once for "water in the oil" that turned out to be condensation in the dipstick tube.

 

OEM replacement along with a coolant flush and an egr delete

 

You need to figure out exactly where it's coming from before throwing parts/money at it. I'd start by getting an oil analysis done to MAKE SURE there is coolant mixed in the oil. You can have this done for under $30.

Oil coolers don't just fail out of no where, it's a prolonged process. My guess is this truck was having issues before the oil cooler ruptured (if that's what actually happened, but right now that's where we're pointing fingers with the limited information given).

Some more info about the day it lost power would help... any codes? Was it even scanned? Any other symptoms? Any smoke coming out?

What happens now when you try to start it?

My guess is the delta between oil temp and coolant temp was out of this world.
