Ok I realise I already have a thread up here.....
-Also posted in 911 forums.
Got a pretty big scare here. Just got stationed up in indian head md, dont really know any mechs or shops yet so ill see if you guys can help me pre-diagnose the issue.
Was pulling out of CVS this evening and got on it, nothing crazy maybe 15lb's of boost, when all of a sudden it began to sound like it was defueling then this huge "POP" like a hose blew off or something, immediately following the pop the engine started running extremely rough (boost gauge fluttering like crazy, lack of accelleration power) and shaking VIOLENTLY, to the point of being hard to drive. Also it sounded like an exhaust leak or something was making a really loud "clanking" noise.
Immediately pulled into a parking lot popped the hood scanned everything above and below (left the truck running because i CANNOT get towed back onto base) and couldnt find any leaks and all hoses were secure. I bit the bullet and made the decision to drive it back to base appx. 15 miles, when about half way back the clanking noise stopped, however it still shakes really bad at low rpm accelleration, and the boost gauge is fluttering like crazy still, and EGT's were 100-150 degrees warmer and total lack of power in every gear.
I dont have any tools down here they are all still in storage @ camp lejeune, so im searching for someone in my new unit who has the hook up but until then anyone ever experience anything similar?
6637mod, 4" straight exhaust
-No white smoke
-When it did happen there was ALOT of black smoke
-Fluids all look good, oil is good and coolant lvl is proper
Also if anyone knows anyone or is close to the Indian Head/Waldorf areas whos interested in tackling a project feel free to shoot me a pm, i have a big cedit card, just didnt want this to be the reason i start my build on this truck and dont have a 2nd vehicle to drive yet!
Would the dealership be the best place to go and get codes pulled? Gonna check the oil to see if theres any coolant in it as well. I have a buddy who lives appx 2.5 hours away gotta wait till payday and gonna attempt to make the trip there, just wanna get codes pulled and try to pinpoint the possible issue before getting it into the shop. Were thinking possibly head gaskets.
Ok ive searched a million threads over the past week, what i originally thought the problem was is not the problem at all. Some updated info:
-Egts are running roughly 100 degrees warmer,
-Im definitely leaning towards a turbo issue here, it lacks boost, seeming like theres a significant boost leak somewhere. Would this cause the MASSIVE vibration in the entire truck when running in Overdrive between 1500 & 2000 rpms?
-Ive got the shop on base with tools here to use so tomorrow morning first thing im going to check the ICP sensor and see if it has oil on it, also check out the UVCH wires see if theres a problem there and thoroughly inspect the turbo to the best of my ability, and try to clean out the EBP tube and see if that helps. Tonight it wouldnt start, wouldnt crank even just clicked, thought i had bad batteries so i jumped it off the drivers side battery and had them both tested (and turned out better than good, both batts over 1000 cranking amps), not sure whats going on there. Every single thread ive looked in with similar issues (lack of power, turbo surge, etc) dead ends with no fix or solution follow up ever posted, that wont happen here. If i dont get it figured out tonight its going to a local shop and im gonna take the reaming on the wallet. This is my only worry in the world now, and i will stop at NO expense to fix my precious
heres a link to the best quality sounding video i can get, sounds like a frickin rattle snake and shakes so bad, if i were a female id prolly be making some funny noises (sorry for the vulgarity thats the best analogy i can come up with!)
