1994appyhauler

Hi all. I encoutered a really wierd problem last nite that I hope one of yo can help meidentify. I have a 1994 dodge ram / 12v cummins engine. (obviously). I was driving down the road last night, Hauling my gooseneck trailer fully loaded, and went to pass some other slow *** moving trailer. I floored it on the pedeal, and as I was passing the guy, I heard a loud blowout "POP / WOOSH" soound, similar to a blown out tire, followed by a deflating whoosh.

at first i thought it was a tire but it seems to be something inside the engine compartment. as i continued driving, if I woul press on the accelerator (at about 1500 revs) I would hear this wooshing sound, and it got louder the harder i pushed the pedal. I decided to keep dirving, because my gauges were all normal and the engine would idle fine.

At later inspection, I noticed some sort of fluid all over the front end of my engine that I could not identify (brownish in color) also, and I am not 100% on this, the truck seemed to handle differently afterwards. I keopt driving after i inspected it and the problem seemed to go away for the most part.

has anyone encountered anything like this before? I am completely mistified.

The fluid part stumps me but the boom and whoosh sounds like a lower intercooler boot. If so probably the one on the pass side. Do you have any excess black smoke, egt gauge pegged under throttle?

..................the pass lower intercooler boot is notorious for making contact with the inner fender and when you drop the hammer boost goes up boot inflates to a like balloon status, and if your truck is bombed at all your prob seeing higher boost anyway will increase the need to replace the boots with some good aftermarket ones from Piers or Haisley or BD

yeah, my girlfriend was following behind me and said i was putting out more smoke then usual. the fluid in my engine compartment wasnt too heavy, maybe an oz or so, just strange that is was fresh and wet. I will check the intercooler today.

Someone playing a game on you and putting water in the intake system or if bombed did rain get in or? Maybe when the boot blew the H2O shot out?? dunno. If you have a boost guage you should have considerably less boost and mass black smoke.

Sounds right to me.Lower intake boot will blow off the IC occasionally.Its happend to mine a couple times and its exactly as you described.Just be sure to get it fixed quick since now your sucking dirty air into the engine.

Ok everyone is right on the inter cooler boots blowing. But for the brown liquid you saw, that was engine oil. I have blown boots on my truck and if you continue driving the force that turbo is creating actully allows some oil to bypass. After you correct your problem with your boots, check them again ina few weeks and see if you still have any oil present. If not your goood to go, if you do check the seals on your turbo. That is what my diesel mechanic did to mine.
