help needed bad.

well, it started yesterday i was smelling a strong "burnt oil" smell but it went away and i thought it was just coming from outside. today i was on my was to a town over and i smelt it again as i came to a stop in the same place i had smelled it yesterday. picked up a buddy and went on drove about 10 or so miles and smelled it again and then heard a screeching noise so i pulled to the shoulder and turned off the air conditioner and the noise stopped. truck ran completely perfect and nothing out of the normal. on the way home i raced a buddya dn truck was completely cool. got home about 30 mins ago and decided to take a look at the air conditioner and when i opened the hood the engine was soaked with oil. mainly the passenger side. the alternator and the fan and front of engine and the complete passenger side fender even, checked the oil and it was at the add line so i dont think i ran it too low, whats up, does it dound like my killer dowl pin? thats all i can think it would be, however where do i go from here? i am a rookie to this stuff. any help at all appreciated, thanks

Yes, sounds like the dowel pin, sorry

check to see if the oilis coming from the right front of engine behind the idler pulley.



if so... KDP

 

[Rammin On]

If the KDP is the culprit ... . the leak will be on the LEFT side on the engine under the fan hub. Clean the engine and lok for the leak ... . is your oil filter tight????? When did you last cahnge it??? Lately?? There may be 2 oil filter sealing rings there ... . the old one may have stuck on and the new filter screwed on the old one ... . will cause a leak!!



Keep us posted

there is no oil on the oil filter or around the sel there. i looked for that earlier, i am getting ready to go out and see if it is coming from behind that pulley or the hub. thanks guys ill post agian in a bit.

i can't seem to see where the he** the oil is coming from. it doesn't seem to be leaking anywhere. also to update my story i got to thinking and yesterday my woman and i were driving i let off and started to accel and i heard a noise ( hard to describe) from under the hood, it was like a swoosh clang sound and it felt like i ran over a slight bump. im sure this is when it came out. i dont even know what the hell the thing is let alone how to fix it and all the other problems im going to run into, im a rookie. ill continue reading about this thing and hopefully learn any insight would be great cause i dont know where to start! thanks so much for the input so far,

Could you tell if it was motor oil or heavier gear oil? The vent, if it's 4wd, is on the pass side under the airbox. These are sometimes known to puke oil and make a mess on that side of the underhood.

 

[dcash]

illflem,

i was hoping you would read this! i don't know really what kind of oil it is. i just assumed it was motor oil, i think it is motor oil, it's black and doesn't seem to be real thick but i dont know. it's a 2wd does this make a difference? i hope this is the prob and not the kdp!! let me know what to look at and where (in idiot steps,lol) and thanks again for the input,

Sounds like a blown AC hose, and the AC oil spewed all over the engine - probably a leak down close to the AC compressor - run the engine, turn on the AC, and see what happens as you watch around the AC compressor... Could have damaged the AC compressor if run without oil, and you sure wouldn't be getting any cold air...

 

[dcash]

i am very hopeful that it is the a/c and not the kdp, im sorry to be so ignorant but where exactly is the a/c hose what does it look like, im not sure about the components really. never really had problems with a cummins before so all my knowledge is focussed on performance thanks for the help

Your getting advice and pointers from folks that know alot about these rigs. My only suggestion would be for you to purchase the factory manual. It's easy to read and has excellant graphics. I learned a tremendous amount from this site, but the manual has helped me put things in perpective. Good luck finding the problem.

 

[M Barnett]

Too find out if it is your air conditioner, simply turn the air on with the engine running. If it won't blow cold air, a line has blown. The KDP will break out of the timming case close to the idler pulley for your fan belt. Actually I think the hole would be right under the pulley on top of the case. I would clean the mess off with gunk and then try to find the leak. .

i checked to see if the air was cold, it was blowing cold or cool air at least within the first minute i turned it on. i aslo checked around under the hood with ac on and revved the motor, I couldnt see a drop or any place that was leaking so sometime today or tomorrow at the latest im going to clean the he** out of her and see what i can produce. thanks so much fellas im going to need all the help i can get!!



p. s. no-strokin, i have a haynes manual i have been refering to for this and that. it does help me break down what some of the info i cant understand that guys say on here, lol. and sometimes it works in reverse order.

Be careful cleaning behind the fan area, if it is kdp damage water can get in your oil pan from the crack.

 

[Cummins Corvette]

If it is your KDP I think there would be a visable crack in the aluninum case. Here is one picture of a cracked case. The crack is kind of hard to see, but it is the lighter looking section smack dab in the middle of this pic.

Here is some pretty good info on the subject along with some good pictures.

You might want to check the oil line to the turbo too. I haven't heard of any problems with it, but is on the pass side along with the oil cooler. The cooler looks like a plate bolted to the side of the engine by the oil filter. Perhaps one of the lines to it has a leak.

I hope this helps.

Chris reminded me of another potential leak area I've run into. There is a short, 2-4 inch hose low on the block, pass side, it's the return line from the turbo. It giving loose wouldn't explain the pop you heard though.

 

[dcash]

i cant stress how much i appreciate this info guys! i am going to check it out further in the morning. i will post my findings, heres hopin for a blown hose and not the KILLERdp.



illflem, i am not certain theat the noise i heard had any relation to my problem, however if it is the kdp then it would make sense that right after hearing it is the first time i smelt the oil and the next day i discovered i had a problem. im going to check the oil cooler and the hoses tomorrow morning!



thanks again, if it werent for this info id still be scratching my head wondering why the hell my truck was masked with oil until i got the money for the dealer to rip me off!

i cleaned it up today at least as best i could without using water. ( i am afraid to get water in the oil if there is a crack) i started it and reved and what not looked all over from abov4e and beneath and nothing, also the truck was completely normal sounding and running. so i decided to turn on the a/c and see if that made a difference. i turned it on and looked and looked and found nothing BUT when i revved the engine with the a/c on, it made a loud high pitch sqeueeling sound? any suggestions? thanks in advance,

man am i missing driving my truck.

The squealing could be coming from your oil soaked belt (if it is) because of the additional load from the ac compressor. Someone somewhere makes a florescent tracer you can put in the oil, then you get a black light and you can see where the oil is coming out. That might work on yours. Try taking off your fan, clutch, and bearing. That will expose the area that cracks when you loose the kdp. The fan nut is reverse thread so turn it like you are tightening it to take it off (clockwise). The bearing is held on my 4 bolts. I would take off the shroud too just to make things easier. Take off the coolant overflow tank and the windshield washer tank, the two or three clips on the top of the shroud, and I think you should be able to just lift it and the fan out of there once you get the fan nut off. Then just take out the four bolts holding the bearing on and take a look at the case to see if it is cracked. I would only go this far if you look forever and still can't find the leak though.

another post cleanup report

well, i have a guy in the next town over that is VERY knowledgeable on these trucks(extremely), i called him this afternoon and he told me that it was more than likely my kdp and i needed to take fan belt off and clean extra good again, then start it rev a little to let the oil pressure in case get rockin and then look for leak underneath the fan hub. i did this, i maticulously cleaned the engine with brake cleaner and took the belt off, then cleaning even more i started it. i revved it for awhile then even more and let it idle for a sec or two then (i cycled the a/c while revving, i dont know if it would even work without belt but just curious to the results i would get) and nothing no noise or nothing out of the norm. i looked and looked and found no oil at all around the hub but i did see just a bit that looked a little shiny above the fan hub to the left, right under where the alternator bolts to the block, just a bit and it could have been some i didnt get removed. i dont think i stuck my hand in this crevice to clean very thoroughly. oops, well guys any thoughts. i am going to call the guy (Ron) in the am and tell him about my results and see if maybe he will come look for himself as i am cautious to drive it not having evaluated the prob for sure.



still tryin... ... .
