I have a coolant leak somewhere on the top of the engine running down to the oil pan and bell housing. I have done some research and discovered it could be the coolant inlet tube to the turbo.
View 14 RepliesThe same day that I noticed my coolant temp was running high as I was driving around in my 2011, i was driving around in my corn field cutting wood and i noticed i was dragging something under the truck. when i got out and looked under the truck, there was coolant running down all over the bell housing and oil pan. i was a bit worried that it was my head gaskets leaking but once i got it in the shop and looked at the heads, all looked good. i wasnt sure where it was coming from! so i looked up common coolant leaks on the 6.7 on youtube.
First video was one of the coolant line on the turbo leaking. so i crawled up on top and shoved a mirror down by the turbo and sure enough i could see coolant leaking around the connector fitting coming out of the turbo. apparently the gasket goes bad around this fitting allowing it to leak. i was just wondering if this is really that common of an issue? I did the work myself. and its not really that hard to get to the turbo, its just time consuming removing all the crap around it. all i had to do was remove some connectors that were attached to the plastic intake and remove the intake then you can reach into that fitting. total time was around 2.5 hours.
So I have a bit of an oil leak, bell housing drips once or twice while it is parked for a day or so and usually has a drip hanging off of it. Where the starter mounts also has some oil and there is some of the driver side. The valley is totally dry and I have new CAC boots so it isn't coming from up there. When I look through the inspection port it doesn't look like it is from the rear main. I figure this leaves either bedplate or cam/crank sensor. Any thoughts on how to narrow it down further? Maybe put dye in the oil? It looks somewhat oily up by the cam sensor but it is so hard to see that thing I can't tell very well.
View 10 RepliesOnly when running heat or defrost, coolant leak looks like it's coming out of the bell housing. I have a supercharger so very difficult to see behind motor, but with inspection camera, heater hose lines look dry. firewall looks dry. No coolant in cab. No steam on windows or smell. Pretty sure not casting/ freeze plugs because absolutely no leaking with heat off. Can run for days with no loss, then turn on heat and within minutes/ seconds coolant puddling in driveway. Is the hose that runs through valley pressurized only when heat is on? I saw a few older threads but as far as I could tell none specified heat on/ heat off conditions. Just started problem after doing some other work, hoses were off radiator and intercooler, replaced radiator. None of those connections are the culprit.

My '96 ranger, 4.0, auto transmission has developed a coolant leak. It is at the rear of the engine, passenger side, at or just above the bell housing. I can't quite see where it is leaking from even using an inspection mirror from on top or underneath. The engine runs great. I just finished replacing the power steering pump, ac compressor, dryer and hoses. What is back there? Freeze plug? Do I fear the worst and that the head or block warped? I may drill a hole from the passenger compartment to try and get a better view.
View 4 RepliesMy 2003 6.0 has a coolant leak. It leaks slowly while not running and more quickly while running. I have about an 8 mile drive to work every day, I can make it there and back without having to add coolant but I'm cutting it pretty close by the time I get home. In short I go from the max fill line to bone dry in about 24 hours.
With the truck running I can see water getting slung around all over the front of the engine but the majority of it seems to be coming from around the two larger pulleys in the middle. I've read that this can either be the crankshaft seal or the water pump, any way to know for sure? Any other possibilities?
I am having trouble finding an oil leak on my truck. the oil is coming out of the weep hole on the bottom of the bell housing where the cover over the torque converter is. There is no oil in the front of the valley under the fuel bowl/hpop. But there is a small puddle in the rear of the valley. I have changed all the turbo pedestal orings. Maybe the ebpv rod? But i cant see it leaking from there so im not sure where its coming from. Also have to do the front main as is leaks a little onto my lower radiator hose. How difficult are those?
View 7 RepliesI have a small oil leak that is showing up under my turbo compressor housing. It's starting to show a little in the valley. Not a big leak, just not sure were the source is and would like you opinions and recommendations. I have been cleaning it up every few days, drive it then use a mirror and rag to try and locate the source.
Here are some pics, I hope I took some that are good enough. Unfortunately I cleaned up the oil before the pics, but I circled and marked the location.
Concerned about the turbo, but I don't understand this leak since it's not coming from the center section. The turbo drain pipe is new and it does not seem to be coming from there. The leak is not enough to show a change on the dipstick the last 3-4,000 miles as far as I can tell.
I changed the oil on my '98 Ranger 4.0L V6 yesterday and noticed a little bit of coolant on the bottom of the bell housing. It wasn't much (yet), but it was trickling down from above on the driver's side. I couldn't see clearly behind the engine on top without removing some stuff, but I could see where it looked like it was dripping onto the bell housing, ca.3/4 of the way up on the driver's side. Where the leak may be and how to fix it? As I said, it's only a couple drops now, but I'd like to nip it in the bud.
View 4 RepliesMy serp belt started squealing so I pulled the thermostat housing to inspect the rubber gasket. It looked OK, but I cleaned up both surfaces and replaced with a new gasket, and put it back together. The housing was replaced just a couple months ago along with new hoses. It was not corroded and OK to reuse.
Started the truck up and saw a slowish/steady drip of red Cat ELC dripping on the driveway. Opened the hood up again and carefully inspected around the thermostat housing - no coolant is leaking there.
I did notice the same slow/steady drip coming from just behind and beneath the thermostat housing. See in pic, this is where it is dripping. One other question, what is this plug for on the side of the water pump?
I bought a 2003 F350 with the 6.0L. It had injection, EGR, and oil cooler issues. I tore into it, did the injectors, EGR delete, new oil cooler, turbo seal kit, and several other non related things. Put everything back together and when I started it, it was leaking oil at the paste of 1/2 qt and minute. I did all sorts of searching on this site and went back to work on it.
I re-installed all new gaskets and O-rings, replaced the ICP and IPR sensors. Started it back up, exact same thing. From what I can see, oil is accumulating on top of the oil cooler housing around the area the turbo oil supply connects. But, its not leaking from turbo supply, or from where the filter housing attaches. Im at a loss. Its definitely somewhere on top of the engine and running down the back, only when the engine runs.
I have a 06 f250 that has a coolant leak in the front of the engine. It's was leaking about a month ago replaced the water pump it stopped. Then about 2 weeks later it started back up again. It only happens when the engine is cold. But once it warms up it starts leaking again. I am confused as all get out on this.
View 1 RepliesCame out of a turn, went to grab third, clutch went to the floor and didn't come back. Stopped, pumped pedal for a bit, managed to get into first and milked it home. There's nothing leaking, but fluid level was low. I topped fluid, pumped pedal and bled the block at the tranny, pressure came up and I was able to engage gears. Pulled into garage and same issue, no pressure and clutch won't disengage. Pedal is soft. I'm thinking I managed to get some air in the system. Question is if the slave failed, wouldn't I have a leak at the bell housing?
Do I have to drop the tranny to bleed the slave? Also, my stock clutch on APR stage 1 was doing ok before this issue. There was chatter and/or other noises in the clutch at take off but no real issue with slipping. I'm thinking I'll go ahead and replace the clutch. I'll be dropping the trans on a rack in my friends shop.
I have a motor oil leak on a 1991 Chevrolet S10 pickup, 2WD, 2.8L, manual transmission.
The leak is around the bell housing area. The oil covers the bell housing and the transmission.
I think it is either the rear main seal or the back of the oil pan gasket. But how can I know for sure? It is difficult to see the back of the oil pan.
Would the oil INSIDE the bell housing be proof positive that it is the rear main seal? I have not looked inside yet.
I recently purchased my 2011 F250 Powerstroke a week ago today with 87000 miles on it. the dealer assured me they did all the maintenance on the truck before i was able to drive it home. I noticed on my dash that it kept popping up i needed to change oil soon.. so i got out to investigate and realized i was about a quart low on oil so i looked around more and am seeing that i have a leak coming from the back of the engine running down to the oil pan.. I have not noticed any on on the ground at all but what this leak is coming from...
View 14 RepliesWhile servicing the bosses 121k 6.0, I noticed the coolant resevoir empty. It took 1 1/2 gallons to bring to proper level. Returning under truck to install drain plug, I noticed coolant coming from rear of the engine(right side). And of course Ford has changed the cooling system cap, so I wasn't able to pressure test it to pinpoint the leak. Started the engine and seen coolant coming from the left rear as well. I've been reading here to see what others have been seeing, (EGR cooler, head gaskets). With all the heat shields,not much room to look.
After work I did go and buy the adapter to test the cooling system. With any luck I will be able to see leak better.
I have a small coolant leak coming from the passenger side near the back of the engine that forms a spot about the size of a dinner plate if it sits for a few days.
One thing I noticed is if I turn off the AC selector switch when I park I will get the drip but if I leave the switch on MAX AC when I shut the truck off I do not get any leaking.
It is definitely coolant and not just the condensation from use of the AC. If I haven't used the truck for a few days or if I have run it with the AC off I will get the drips.
If I run with the AC on and leave the switch in the on position when I shut the truck off it won't leak. I have tried to locate it from looking above and below but can't determine where it is coming from.
I've got a leak that appears to be coming from the secondary fuel filter housing (the one in the engine compartment)... It's not coming from the filter, but from the side, where there are 4 allen bolts that attach a fitting to the side of the housing...Can I change out the gasket for that piece? I've already tightened the bolts, but the leak persists.
View 14 RepliesNoticed a small oil spot on my drive way where i park my truck the other day. Got up underneath and saw it was leaking from a rectangular rubber grommet on the front of the transmission bell housing.
What could be causing this? Have heard a few different things, turbo line leak, turbo pedistals, HPOP leak. Seeing what Super Duty Nation thought of the problem. Going to the dealer sometime this week.
Removing 4.6 triton from 1998 F-150. Is there a way to remove the top 2 screws connecting the engine to the bell housing without removing the intake manifold? Although I don't mind removing the intake, I am doing a 4.6 to 5.4 swap and would rather attach the intake prior to putting the 5.4L back in. Figuring if I cant get it out that way though, I wont be able to put it back that way.
View 4 RepliesI have a 1990 F-150 w/351 that I knew had a coolant leak at the back of the engine when I bought. It's a tinker around truck, something for me to play with.
I've traced the leak back to a metal tube/pipe that sticks out of the engine compartment just below the AC housing. I cannot find anything in the Haynes manual or a diagram on the intertron that shows what this is and if it should have a hose on it or...?
