My 97 has started to slowly drip what looks like oil on the driveway. I crawled up under it and it seems to be coming from the big pipe that goes from the turbo up front to the intercoller (I assume its the intercooler but I could be mistaken). It only leaks a tiny bit but Id like to go ahead and get it taken care of before the problem escalates. Why would it be leaking from there? I didnt even think any oil was supposed to flow through the intercooler lines. Thanks guys, Justin
thats not your problem. th eIC lines will be wet and the boots wet, but they will not drip to the gorund and make puddles. look elsewhere for your leak.....
Unless your turbo is going out. How many miles on the truck? I have had turbos go out on our 60 series Detroits and they pump oil into the intercooler. If you don't try and clean out the intercooler it makes the truck smoke enough to make a pro sled puller envious, seriously.:doah:
So its okay for the lines and the boots to be wet? I put it up on the lift today and took a closer look. The Intercooler lines are wet and just before the pipe turns up it looks like a tiny bit collects and might cause a drip or two every now and then. Is that too much dampness for the lines to have? I guess I should clarify a little bit about how much it drips. I only noticed it after it sat for two days and there was only a tiny bit of oil on the ground. I just hate for my trucks to leak anything so if I can fix it I want to, especially if its going to get any worse.
dampness at all intercooler connections is normal for a turbo diesel.... if it is excessive you are getting extra oil into the intercooler someway, either by excessive engine blow by, or a turbo seal leaking into the intake side. are your IC clamps tight near where its leaking?
I had a customers truck start leaking on him I checked all over the pipeing and the seal on the drivers side head gasket was leaking.Check the head,valve cover,pan gasket just to be sure go clean it off at a car wash then check it ast home.
Leak Is your leak diesel fuel? If so, you may want to check your return fuel line(s). They are known to fail. Do you still have prime when you try to start the next day? If it is hard starting, it is a good indication you are losing fuel at the lines.
I didnt even think to check if it was diesel, I just assumed it was oil. How long would it take to start if it were losing its prime? It does take a little bit longer to start in the mornings but I just thought that was because it was cold. It never takes more than just a few seconds to start, but Ive noticed if I push the gas pedal slightly it starts almost immediatly. Also, when I shut the truck off there is a hissing sound like high pressure air escaping through a small hole. The noise seems to be coming from the general area that my leak is coming from. Ive been to busy to get it up on the lift and check for loose fittings but I didnt know if this was a normal occurance or a sympton of something going wrong. Im driving cross country next week (not in my truck) and plan on spending as much time as it takes to get my truck in top shape when I get back. So any suggestions of possible problem areas are welcome.
Fuel Leak I too had that problem. I thought it was oil because I thought diesel would evaporate away and not leave a stain. I was wrong. There is an excellent thread on the TDR site entitled, "Fuel leak fixed - lessons learned. It is by WBusa Try the following thread: http://turbodieselregister.com/forums/showthread.php?t=127562 It tells you how to check and fix your problem. Good luck. Teacher
Yes, a lot of pressure is built on the high side of the A/C system. Once the pump quits running it start depressurizing inside the system. This is what you are hearing, or at least I think thats it.
check the boot for a small hole or crack. On some diesels , a lack of backpressue at the turbo will allow the seal to leak. That might also be where your oil is dripping from.
Well I went to the car wash today and completly hosed off the engine. The wheel cleaner works wonders for removing dirt and grease. So the entire underside of the engine bay is now sparkling clean and I cant see any sign of a leak anymore. Ill keep a look out for it over the next few days and see what happens.
