I was driving home From Lethbridge Alberta to Saskatoon Saskatchewan.

About a 600km drive.
After about 40km away i noticed some weird kind of bogging.. almost like the car hit a wall and wouldn't move but went away. I know my plugs weren't great but they were fine and i planned to change them anyways so i figured that may have been the problem.
After quite a while the car started to do it a little bit more.. me thinking its either sparks not firing properly or that something wasn't flowing right with my injectors.
Then following someone around 70mph(110km/h) i noticed around 3000rpm it was doing it a lot and when i gave it gas and it went a little over 3000pms it quit.

I then pulled off because i needed gas. This was close to about 400km into my trip getting a lot closer to home.
I carried on and was driving at about 130km/h when everything completely loses power. quickly although i was on the gas my RPM's were dying. I tried to clutch in to perhaps downshift and try and get more fuel to the engine but it completely dies and i coast to a stop.

A funny burning smell came from the engine. May i remind you my oil pressure seemed a little low and my water temperature was PERFECTLY fine. I got out and checked the oil. FULL! I had about a Quart of oil in my car so i topped it up just to be sure and when i looked under the car nothing was leaking. Then i tried cutting the fuel and starting it again to see if it was maybe a temporary thing. NOTHING! the car would turn over but i couldn't get it to fire over 500 rpm. Then smoke started coming out of where you pour the oil in? weird?.... and it smelt like burning plastic/brakes/clutch..

Luckily for me my dad was some where behind me and i was able to get home.
So i took one last try to start the car! it fires and starts. When it starts there is a **** load of white smoke coming out (cracked water jackets or seals?) and the engine sounded really sick and grumbly.. i think one rotor lost compression?

WHy i think this is funny because the car was rebuilt 10 000km ago (By Joe at RPM Performance) and about 80% of the miles at least are all highway..

Has anyone had this problem or know what the hell happened and is exactly wrong because im pretty confused to how it happened..?
The engine is a streetported s5 turbo engine.. that ran great up to that point and really gave me no problems...


Now i have to tow it home 180km

Hey Chris I replied to your pm, check you compression first and we'll go from there. I added my new shop and cell number, so call me in the morning if you want to.

 

could be a bad o2 sensor or something which messes up the read on afr and the bogging could be from a not so healthy mixture

 

White smoke definately sounds like an internal coolant leak. Smoking/burning smell out of the oil cooler sounds like the thermal bypass in the oil cooler may have **** the bed.

 

Hmm im not entirely sure guys but its the *****..

To me it sounds like coolant is inside the rotor...rotor housing?.. because there was tons of white smoke upon the second time i got it started.. so im not sure?..
As for the levels the coolant was the same and so was the oil. My gas was lightly premixed before i had left lethbridge too and i didn't use any premix filling up after that...

uber confused.

 

does it need to be premixed?

 

It doesn't neccesarily need to be premixed but helps keep everything lubed up a little nicer.
