steveg posted a topic in Operation and Maintenance: 450 Model, 2005-2006, dieselhi everyone, I have a 05 450 Smart cabrio gasser... I didnt see where I could post for gasser so i went with diesel hoping someone could help.. I realize not many 450 gas cars made it to the states let alone Canada, so Im a bit out..orphaned.. ok, my cabrio 450 has 50k miles on it, self serviced and maintained, while driving home last fall about a mile from home it suddenly lost power and started blowing blue smoke out the tail pipe and oil all over the rear of the car, i limped it carefully the last 1/2 mile and shutting down I had oil coming out of the exhaust, and all over the rear. The dipstick reads low now, and after disassembly of the intake from the turbo up to intercooler i found oil right to the manifold, intercooler, and into the exhaust. I did remove the turbo, and there seem to be no play in the turbine or shaft , i know I will have to replace the plugs (all 6) and clean everything up. thats a given... I have read where turbo failure is common with 450 diesels, but what about the gas models? it did have the whine just before it failed which makes me think turbo seals, but how do I check it? I am a highly qualified mechanic, but this has me stumped. I have new plugs on order and will finish disassembly of the turbo tomorrow. it is a garrett gt12, anything else i should check? I dont want to get this together and find something else filed.. email me directly if you have any ideas, insights or questions. steve george firstname.lastname@example.org
TorqueJunkie posted a topic in Operation and Maintenance: 450 Model, 2005-2006, dieselHello guys, 450 petrol (roadster) in deep winter (-20C) here. Couple days back I had an incident.. A minute after start, oil started spilling everywhere. I noticed that only at red light, after 3 kilometers. There was a lot of white smoke coming from all sides of the engine. Opened it up and wow, view is terrifying. So what happened: oil started spilling out from dipstick pipe, getting all around manifold and turbo = a lot of white smoke. Also it seems like oil did somehow get in to burning process, as there was a lot of while-bluish smoke coming from exhaust as well. I lost one liter of fresh oil that day. The engine was serviced recently (a month ago) and upper breather valve was replaced with generic one: original valve was failed (stuck partly open), I could not get whole pipe assembly in time. This is what I replaced it with: While waiting for a friend to tow it away, I immediately checked upper valve and it was operating fine (detach one end from throttle body, blow, then pull with mouth). So it seems to be OK. Couple hours later, when in garage, I checked lower breather pipe (part A1600180112): I found only very little ice in it, not nearly enough to clog up. I cleaned it anyway and assembled it all back... Today it happened again. Noticed it quicker, lost only 0.5 liter of oil... So now I'm lost. Oil is coming from dipstick, because there is pressure buildup and something is blocking it's way out. But why smoke from exhaust? Is oil getting sucked through upper breather valve? Can't really confirm it, but first observation is that the most of smoke from exhaust is only during negative boost pressure (when idling and upper breather valve is open). But the biggest question is: what I missed? Should I also remove and inspect TIK pipe? Or can it be caused somehow by upper breather valve? Something else?
Hi everyone! I have one problem. When the car is warm and leave it 10 minutes then i start engine i have blue smoke for 5 seconds, and then stops. if I add a little rev then immediately stop smoke. And when i connect the battery to multmetar it shows 12.5 v after 5 sec it shows 14.5 V in same period as smoke Thanks.
