![]() The worlds best, most cost effective Ford Powerstroke remanufactured engines. Doing this might save you a lot of work and money. If one head holds air, then go to the other head and do the same. This is best done if the engine is at operating temp before you put air to the head. If the crack is really small, it may take a couple hours for the pressure to show on the gauge. If that head is cracked, pressure will register. With a pressure gauge in the degas bottle, pressurize he fuel rail with shop air. ![]() You can pressurized each head individually by adapting an air fitting to the front of a cylinder head. Many shops want to replace both cylinder heads but there is no need to fix something that isn’t broken. Asheville Engine sells o- ringed cylinder heads which give you reliability without the worry of blown head gaskets. But if I were you I would just save up and do studs and either egr cooler delete or bulletproof EGR cooler. New cylinder heads will fix the fuel issue. Go drive it on the freeway slow down to 40 mph then put ur foot to the floor watch the pressure gauge if it spike up fast and past 16 psi its head gskt but if it increases slowly above 16 its ur egr cooler. If you have diesel fuel in the coolant, you need to buy new heads. When a crack occurs, diesel fuel easily passes into the coolant. The fuel pressure from the injector rail cast into the head (small hole to the left of the arrow) is far greater than the pressure in the cooling system. Cracks are generally caused by overheating and because this area is thin, it is most susceptible to cracking. In this cut away of the cylinder head, you can see a thin wall between the injector bore (where arrow is) and the coolant passage to the right of the wall. This can damage the transmission to the point where it needs to be replaced.Have ever wondered how a cylinder head cracks to allow diesel fuel to get into the coolant bottle in a 6.0 Ford Powerstroke or VT365 International? Here is a picture and description of where they crack. The bad news is that the coolant can make its way to the transmission. This causes the coolant to be pink and foamy looking. Hello, I just got a 07 f250 6.0 approx 3 months ago and I now have oil in my coolant but not vice versa. Cracks can develop between the radiator and the cooler that allow transmission fluid to get mixed into the coolant. Often, the transmission cooler is part of the radiator. The truck runs great and sounds just as good. Had a new bullet proof EGR cooler and a new oil cooler replaced 25,000 miles ago. Many cars with an automatic transmission have a cooler for the transmission fluid.

Another Coolant Problem – A Leaking Transmission Cooler And the cooling system will need to be flushed and refilled. We cover everything from brake to power steering fluid. The oil cooler and it’s gasket will need to be replaced. Discover where and how much Ford 6.0 Diesel Powerstroke oil, coolant and other capacities to apply. If the oil cooler leaks, the engine will still perform normally.įortunately for the customer, a leaking oil cooler is a much less expensive repair. However, a blown head gasket usually affects the engine’s performance. This can cause many people to think that the head gasket is blown. If the oil cooler leaks, the main symptom is oil in the coolant. EGR cooler issues can often be traced to the engine oil cooler, which has narrow, flat cooling tubes that can fill up with casting sand left over from. But turbocharged engines usually have them. Oil coolers are not very common in gasoline engine vehicles. Pushing cold oil through the radiator and water pump may damage them.) The radiator and water pump should be inspected for leaks or damage.The entire cooling system will need to be flushed.The head gasket, of course, will need to be replaced.You may need to replace the radiator as well, and possibly the degas bottle too. If the head gasket is bad, several repairs may need to be done: use either the motorcraft VC-1 coolant flush or some other type of flush solution to help break up the oil/coolant sludge that's found it's way into everything anywhere coolant flows. 1997 f350 4x4 cclb psd 2004 jetta tdi 1999.5 jetta tdi 11mm pump s7 pp764s 3bar map 1986 f350 cc dually 6.9 ats turbo lowered 1984 mark vii 2.4 bmw turbo diesel. This will result in a white cloud of sweet smelling exhaust.Ī blown head gasket can be verified with a compression test. We have had egr valve, head gaskets and turbo replaced recently and truck was fine for. Coolant can also leak into the combustion chamber. This results in the brown sludge that can be seen in the top of the radiator, and the coolant reservoir. When a head gasket fails, oil can leak into the cooling passages and then end up in the coolant.
