I have been having trouble with my 325 as far as getting it to run right. I just recently replaced all the injectors and the fpr and it ran good for awhile around town. I took it out on the highway and I was going about 70mph for about 10 miles then it acted like I was out of gas. So I pulled over and the only thing that was wrong is I had smoke coming out of my air filter. When I tried to start it back up it turned over for awhile and then locked up. I'm assuming it locked up due to the cylinders filling up with gas cause it has done it before but I'm not positive yet. Can anyone help with me this?

Smoke coming OUT of the air filter? Like out of the airbox housing?
Pull it and see if there's anything clogging it/the afm up?1988 Atlantisblau Euro/Japanese 325i Cabriolet

smoke out of the intake is usually a good indication that your timing is fucked up and you're backfiring through the intake.
check your cap and rotor. I highly doubt that something clogging the AFM and causing smoke.'84 318i M10B18 147- Safari Beige

Actually sounds like a stuck open injector.Comment

I just put brand new injectors in them, so I'm not really wanting to spend more money on new ones. And no there's nothing clogging up the afm. And the only reason I wouldn't think it's the timing is because it has been running fine and then in the middle of driving it this happened.Comment

What about the cold start injector? I had a bad temp sensor and my cold start injector would stay on. My sensor was so far out of range it was ridiculous.sigpic

okay i have an update for you. i just went out and tried to work on it some more. i pulled a couple of the plugs but they were not wet with gas or anything so i put them back in and tried to start it. it turned over and acted like it was about to start then it just locked up...Comment

also this is what happened to the #6 cylinder plug..Attached FilesComment

The picture isn't good enough to say whether the plug is burned, which would be caused by very lean operation, or mechanical damage, which would be caused by the cam jumping timing.The car makes it possible, but the driver makes it happen.

its not burned its broke offComment

so it would have had to jump timing while i was driving down the highway?Comment

Yes, as your timing belt tensioner could be loose. But physical damage to a spark plug usually means big problems. Are they the right plugs??Comment
-
alright... so now with the plug being crushed im looking at my piston being messed up from hitting it?Comment
-
fuck man.. so pretty much buy a whole new head? and also new pistons and con rods?Comment
-
also so this all just basically happened because i had a loose timing chain tension?Comment
