One cylinder not working

[t_marat]

I have been posting about very rough idle (one cylinder not working) while starting from cold in the morning. I changed the plugs, put Beru (back).

What I noticed today is that starting from cold the idle was rough (one cylinder not working, as nearly always). But after I turned off the ignition and restarted the engine (still cold), it was smooth! Coincedence?

nope. its too cold in here to do anything. and I would not dare to took out the injectors, not sure I will be able to put them back :)
At least with my current level of knowledge in E34s.

the comp should have reset. because I took out the battery for more than 24 hours once (last week, when there was -30C).

Dude you really should have a fire or heater or something before yout fingers turn black and fall off :D

I later discovered that I had two broken plastic fan blades, right next to each other. Amazing how rough that made the engine run.

Check the obvious, simple things first!!

I got one plastic fan blade missing. It sounds great - I have no intention to fix it! Everyone should remove one......

Cheers,

Its now -35C (-32F) in here.

Had to spin the engine for a while in the morning. But it started. Last week I changed the oil to 0W-40 (that stuff is very expensive). Engine was spinning without problems. Guess the fuel froze a little.

I had the same issue. Engine started really rough. Ran it for 3 minutes and then switched off the ignition and started the engine. Well, no cylinder miss this time. This only happens when the engine is cold.

Another thing, engine was making a horrible noise at first, for about 4-5 secs. I can't describe that sound, but its not normal. I got a friend with Audi 80 (B4, 2.6L engine!) whose car also makes this sound when starting up from very cold. What is that? Oil could not have frozen, 0W-40 freezeing temp is -54C.

dude thats just real cold!!! have you thought about the oil pan heaters mentioned earlier?

[t_marat]

Car stays in a public parking lot, outside. Those heaters need mains, and there is no electricity plug in those parking spaces. It won't work for me.

leave it idling all night like a deisel?

I dont know man, thats mighty cold...id stay in bed till the sun shined.

Did the M1 0w-40 help much there?

In that weather your gonna have a very angry engine at startup anyways.

lol :) yea it definitely sounds angry

yes the oil helped, the engine spins much easily in the morning.

how far do you drive? Maybe drain that out and save it and go with thinner synthetic? matters on the travels though.

I go to work, come back. maybe somewhere else. usually not more than 80km (50miles) daily.
Why drain it out? Its liquid till -54C. and I would not want to use something very thin, as this is a 1994 car with 141K miles.
