Smoooooke

[the baPhoon]

So i guess i blew my valve seals tonight. I was on the freeway getting on it a bit and (completly unrelated i hope) The truck refuses to upshift and get goin past 95ish. When it hits the point it should shift i hear a loud CLICK and i throttle her down a bit. A few minutes later i keep smelling burning engine oil. Wow thats odd. So me and my old lady get to fridays for a few drinks and as i stop i notice smoke pouring out from under the hood, hooray, same way i blew the valve seals in my 2000 xtreme with the 4.3 YAY :rant:
Now it appears im on the hunt for a reputable syty mechanic in the phoenix area. Luckily the truck came with a mack daddy warrenty that will cover the things ive been putting off (window motor, turbo flutter, trans, oil pressure sender, the whole 9 yards). Ive gotten 1 reccomendation on a mechanic in the phx area and i guess im just fishing for more insight. Ive had a local chevy dealer do some work on my s-10 and i wanted to rape and murder the mechanics. Also i just realised what appears to be oil all over the rear of the Ty in little droplets. I just washed/waxed and applied back to black tonight so im double pissed lol. Any help would be greatly appriciated.

Re: Smoooooke

where is the smoke coming from? if it's coming from the oilfiller cap, you got exesive crankcase pressure, and might broken a pistonring

Re: Smoooooke

Nah i popped off the oil cap and there wasnt any smoke comming from in there. I couldnt really pinpoint the origin of the smoke. It wasnt from the turbo that i assure you. the o the back of the truck is kinda concerning me.

Re: Smoooooke

I woke up today and decided to pop the hood and check whats goin on. I found out that shes a quart low and the oil is BLACK. also i found the missing quart. Its on the crossmember and back, on the rear windsheild/tailgate and the driveway. fun fun.

Re: Smoooooke

Does not sound like a valve seal problem to me. You've got somthing that leaking oil externaly.
Valve seals would not all the sudden make a noise and you'd start using oil.
Find the source of your oil leak.
Maby it was just mad at you for not changing the oil

Re: Smoooooke

Does it tick when running? Do a compression test. And if you have 160's on all and like 95 on one.. well join the club for rebuilds, lol.

But does that explain the oil leak? I suspect a blown oil pressure sensor or turbo oil line. Maybe the oil filter adapter on the bottom where the lines connect to the block. Something external is pumping oil to the outside as-it-were.

Start it up and see where it leaks.

Re: Smoooooke

Could someone exsplain the part about not up shifting? I am on the highway put it to the floor and the r.p.m. gauge goes to 5 and I must let of to get the truck going my truck will only boost ti the second part of the yellow what 10 psi if that? Whats going on any guess would be as good as many others not many here in mass know whats up with these trucks. Thanks much :tup:

Re: Smoooooke

i know for a fact i have a valve seal problem, but i know thats not the oil leak. Im just adding to the laundry list of BS #24 is giving me. Its a damn good thing i was prepared for failure LOL.
IM gona head outside right now and crank her over and see what happens.

Re: Smoooooke

Ok i THINK its the oil feeder from the turbo to the block, its REAL wet and its leaking BAD from the front crossmember. its not leaking from the oil filter or the oil plug but it had blow back ALL over the engine (the front diff, T case and tranny are SOAKED with oil and its all super black, even tho im only 20 miles over my last mobil 1 synth oil change.) the valves seals are leaking way more then they were yesterday morning, HUGE puff of smoke on startup. The smoke i was seeing from the engine appears to be spent oil on the headers/crossover pipe. im gona yank the passenger wheel off right now and inspect to see if im correct on identifying the leak. If i am im probly gona end up taking it in for warrenty work so lets bust out with the phx area reputable Ty mechanics if anyone knows any.

You may also check the oil return line on the right side of the engine, that where I found mine. At the time I was thinking oil feed line too.

Re: Smoooooke

I think im gona have to agree with ya there Lloyd, upon further inspection it seems that the leak is on the drivers side of the block. I havent pinpointed the leak itself but i crawled under the beast (no jack stands in the garage so i couldnt get as far under the truck as i wanted) and i see that its dripping down the crossover pipe on the drivers side, then pooling up on the crossmember and dripping off. Im gona go pick my jackstands up tomorrow and hopefully get my big ass all the way under her so i can actually look up in there without fear of being crushed to death.

Re: Smoooooke

The oil return is on the pass side of the engine. If you are seeing the leak on the drive side, it is most likely the oil filter adapter O-rings need replacing. The kit cost like $5.00 at the stealership. Or it may be one of the oil filter lines as there is a hose section down there as well.

Re: Smoooooke

Although the massive leaking could be an easily-solved problem, the big click, massive blowby, and big-smoke startup lead me to think you might have gernaded a piston. I had similar issues with my first truck. It suddenly smoked a ton under load, so I took the motor apart. I blew a skirt off one of the pistons and destroyed the rings, which caused insane smoke during startup and acceleration.

Let me know what you find out, and if you need any help...

Re: Smoooooke

im probly gona need all the help i can get man lol. it didnt seem to drive any differant other then smokey. The engine itself hasent been smoking but i refuse to drive it. if i did i would have NO oil in it in about 2 blocks. I think i was lucky cause all of the oil leaked out right as i pulled up to the house, theres oil drips from down the street and then a nice pool under where i parked. Like i said i DO have the warrenty but i like doing as much shit as i can so i can get some learning in. Ive worked in the car buisness a while and taught myself all i know but im still a mental midget in the mechanical world and i damn well appriciate all the help you guru's hand me. Thanks guys.

and an afterthought. There is a bit of a ticking from around under the upper intake manifold. It seems to have worstened since the "incident". its got a crappy idle too and the oil press. is still running high but im sure thats just the OPS.

Re: Smoooooke

Do a compression test.

Thats going to be the first thing any shop will do to the motor if you take it in for work anyway. You might as well know what numbers you have before they give you different numbers and try and bullshit you. It doesnt take but 2 hours at the most to do. And can tell you alot about your motor. Plus you can check the plugs.

You wanna know what that ticking sound is. Do this! If you have low compression in one or more then like I said before and others have hinted at, its a broken piston.

Re: Smoooooke

Sounds like a plan.

Re: Smoooooke

Upon more careful inspection (with jack stands now wee) I found the leak. The oil is leaking out of the driver side of the block. It appears to come out of the drivers side header and leaks out of the crossover pipe flange. Hooray piston rings! It doesnt sound bad while it runs but it does leak INCREDIBLY fast. Monday im gona run up to autozone and get a compression test kit and find out which cylinder is the culprit. This along with the trans/turbo flutter and other random crap should be fixed when i take 24 in for warrenty work. Now all thats left is a good shop in the phx area. Monesq reccomended a shop in El Mirage called Newton's automotive that hes takin his Ty to to be fixed and so far thats the only reccomendation ive gotten. If anyone here knows anyone in the phx or surrounding areas that has a good head on there shoulders leme know.

Re: Smoooooke

It would be a negatory on the piston ring. I pulled the drivers side plugs and they are all dry as phx in july. I checked both the lines running from the oil filter and they are both golden. There is another tube that runs above the crossover flange that i have NO idea where it goes. I cant see SHIT. Im quite certain its a line leak rather then anything else. The leak starts at the drivers side of the crossover flange, drips down the crossover pipe, then down the crossmember to the concrete. Any clue what the line is or where it goes? Since i cant see anything im clueless. I cant even trace the hose as it comes out of the abyss that is the 4.3Z engine compartment. GOD I love a challange, which is why i bought this tempermental black beast.

Re: Smoooooke

I had an extremely similar problem with oil leaking in that exact area. There is a bracket that holds up the oil cooler lines right next to the power steering pump. The moron that had the truck before neglected to connect it, and the metal oil line rubbed against the crossover pipe, causing a tiny hole to form. The line looked fine, but leaked after the truck warmed up. I had to remove the lower IC and start the truck up on jackstands to find it. I'd double-check those lines...
