Re: 1.9 TDI into 90q: The wrong kind of smoke

Well, this smokey stink machine has developed a new kind of smoke. It smokes blue oil smoke when power is applied after decelerating down a hill in gear. Like a fairly significant cloud. I've tried a restricter in the turbo oil feed, but this did nothing. It does use a little oil, however its pretty livable, but the smoke pisses me off enough that I'll have to address it.

It acts like valve stem seals, but they only have 20k miles on them, and diesels never pull a vacuum, so I don't know if bad seals would manifest like this. The smoke is blue and smells just like burning oil.

I will probably end up planning another engine pull where I will add the 11mm injection pump, and carefully check over the internals. It still runs like a champ, and starts instantly with no drama.

It is possible that I have ring issues related to the engines past waste veggie oil use. I never pulled the pistons out of the bores, so I will likely have to do that just to take a look. At that point, I'll replace rings. Once a piston comes out of its bore, I think new rings should be installed and bores honed.

I wouldn't be surprised to find coked up oil control rings, but you would think I would have seen this right away, not 30k miles later after running only pump fuel and good oil. :huh:

I will check valve guides and seals and check for any head cracks or headgasket leaks.

In the meantime, I'm taking it on a 1000 mile trip this weekend. Starting a massive house project, so I'm not sure when this will happen. I'll probably just keep driving it and monitor. I hate to throw money at something when I can't really find the issue.

In the meantime, a really good quality TDI to toyota truck trans adapter finally hit the market yesterday, so I am loosely planning my next swap. Put the ALH from my jetta wagon into a clean 2wd, extended cab, early 90's toyota pickup. I will drive the jetta at least another year, maybe two until the body starts to rust through, but may try to acquire a truck and shotgun it across the county next year.

Sorry to hear about the blue smoke issue Dana!

It will be interesting to see what you find. I'm thinking that you're on the right track thing that it's rings. Though in my own research I have found that the AHU pistons have a much shorter crown than other TDI engines and I could be possible that you are having some ringland issues (?) Here's a decent thread on ALH/AHU pistons and upgrade options (even the its TDIClub :we: ): http://forums.tdiclub.com/showthread.ph ... 017&page=5

You check the intake tract? Is the cc venting working?

this is the toyota adapter company, adapter is not on their website yet, but should be soon. http://gastodiesel.tdconversions.com/

Steve, intake is clean, CCV is not vented to intake anymore. CCV system is totally free and clear.

I don't think I have ring land issues since I have perfect compression and no abnormal blowby. I think its either oil control rings, valve stem seals or turbo exhaust side seal. I don't think its the turbo, as the smoke acts to me like it is being produced in the combustion chamber, not the exhaust.

Other random possibilities could be a crack in the head from getting to close to an oil galley when porting or maybe oil seeping from an oil galley into #3 hole via headgasket.

Who knows, no immediate plans to tear it down, but I'm sure I will get curious soon enough. Its so easy to pull the engine, that I am looking forward to it.

I made it on my 1000 mile trip. I had to sit in some traffic in NYC for about 20 minutes, and in that time it started smoking very badly at idle, and then smoked heavily for the next couple minutes after getting moving again. Once its back up on boost and running at a load, no smoke at all. It only used about .75 quarts of oil on the whole trip, which isnt much considering the crazy amount of blue smoke.

I am starting to think it might be the turbo more than rings, it seems like it loads up the hotside when there is no exhaust pressure, then seals up when there is. I guess rings could do this too, but I would expect more smoke under load and more severe oil burning while running it at 80mph.

I am going to run with with the downpipe off and see if I can spot any oil pooling. If not, then run it with the manifold off and see if I have oil from one cylinder in particular or all. If there is oil smoke from them all, then out comes the motor.

Yea, I suppose I hope its the turbo, but I dont really care if the motor is toast. I'm half curious to open it up just to have a look at how it has survived the doubling of its HP. I dont know when I will get to it since I am about to do this to my house, like in 2-weeks.

Toyota truck will be a while out, and it will be 2wd with a locker since I need to maintain epic fuel mileage for commuting. Not sure if that qualifies as a dream truck for anyone else, but I think it would be sweet.

I'm thinking extended cab, SR5 package, pre-96. ARB air locker, air helper-bags with electronic control. Thats my basic plan. Get it from somewhere that doesn't spray magic car melting liquid all over the roads. Something like this, minus the Cuisinart wheels.

I'm probably going to order the adapter now since the dude making them is small time, and I want to get one when I can hang onto it. They are so much better than the others that have been on the market for a while.

I designed it myself, its all done now. Its really simple, so not a very complicated design. I am hiring someone to frame it, side it, roof it and put the windows and doors in. Basically making sure it will be a water tight structure by winter. Then ill do all the interior walls, plumbing, hvac, insulation, electrical, trim etc. I'll probably hire a sheetrocker. I hate sheetrocking, and I'm bad at it.

It's funny, I think drywall is universally hated. I'm planning to remodel my garage this summer and the only two things I plan to hire out are pouring concrete and doing the drywall. I might hang it myself, but I'm sure as hell not mudding and sanding it.

Wrapped up some extraneous projects before house destruction.

My grandpa bought this 53 ford NAA new, used it a ton on the farm. Its the first tractor I ever drove. My dad had it 'restored' by some jackass who messed up almost everything he touched.

Its been with me since february, and I've been through almost every part of it. The main issue was the rear end casing was cracked, so i found a good one and replaced it. I also replaced all the bearings in the rear ends and axles, a ton of seals, rebuilt the hydraulic pump, replaced the rear main seal (two piece seal, WTF) etc etc etc.

Shes running good now, no more oil leaks.

Never a dull moment! Look forward to seeing more on the house rebuild. I'm about to start in on reno'ing our kitchen (hopefully after I finisht the RS4) - and the one thing I am farming out is drywall. Buddy is a superintendent for a construction company, and one of his guys does a slew of side work. He offered to hang AND mud my kitchen (floor and ceiling) for $500, I supply materials. I can't say YES fast enough!

jretal wrote:Never a dull moment!

aint that the truth. I've had a few "WTF am I doing" moments as I am indiscriminately ripping apart my functioning house that I live in and throwing everything onto a bonfire. I will feel a lot better when things start going back up, but the tear down phase has caused some sleepless nights. No risk, no reward, I suppose.

I'll post up a build thread when things get a little further along. I'm going somewhat rouge on this whole process, and not super keen on full internet photo documentation until I've got things a little more squared away.

I set out this weekend to make a camper hookup so I didnt have hoses and cords running all over the place. The plan is to keep the existing well in place, and have temporary power feed that will feed the camper, shop and some construction power outlets. Good Plan, and simple, right?

Saturday was looking good, got my ditch dug. I had to be careful because I was crossing over the main power feed, near the well lines, and well power and over the propane feed from the remote tank into the house. No problem, a little careful shovel work in tandem with the backhoe, and I got things working.

The problems began saturday night when pressure testing the new water system. No leaks, but I wanted to turn the well down so the RV wasnt over pressureized. I try dialing back my well controller, but the gauge doest move. No problem, slap another gauge on there. Interesting, the gauge shows a cycle from 20psi cut in to 100 psi cutout. Waaaay to high. Replace pressure switch, new we have a nice 30-60psi swing.....BUT...pressure drops down 30 psi in 10 minutes, when using NO WATER.

Shit....a quick isolation test reveals a leak under ground or down the well. Sunday morning finds me welding up a well pump puller and dragging the 1/2hp submersible well pump out. Don't worry, it was only 300 feet down there. Anyone need an upper body workout? Try dragging a 100lb well system up 300 feet with no way to stop and rest.

No leaks in the well pump line, check valve in the pump is good. I clean it up, clean the screen, re-secure the wiring and send it back down to its home at the center of the earth.

Then I start digging, its buried about 6-7 feet deep (VT frost protection). I carefully uncovered the whole line, and found that I was loosing pressure where the well line T's to a remote hydrant. Malfunctioning well pump switch probably blew the seal in the hydrant. Fuck the hydrant, I don't need it. I put in an elbow and abandoned the water line to the hydrant, and we are now holding pressure all night.

Moral of the story, project starting off with a bang. Thank fuck I bought that shitty old 3 point hitch backhoe a couple years ago. It paid for itself this weekend.

Finally got water running again last night about 10.

Just getting started, feeling good about progress.....
