    So a couple days ago I my SES light came on, so I took it to an autozone to have the code scanned. I wish I got the what the actual code was but the translation they gave me was there's a vacuum leak. Long story short, I took off the DISA valve and I don't know if it's good or not. The flaps...

    Hello. I'm replacing my intake boots and thought it might be the best time to reroute my positive battery cable. (I routed it incorrectly and didn't have enough slack when I replaced the hard coolant pipes last year) Based on this picture, does anyone know how I can route it without removing...

    Hi everyone, long time lurker but I now have something to post so here goes. I own a 2000 323i E46 (some 246,000kms) with an engine that's in tip-top shape, no oil consumption whatsoever, no nothing. I had the classic misfire issues caused by vacuum leaks and a broken PCV system, but other...

    Hi gentlemen, I did a starter replacement job a while back. Have an xi AWD so it was easier for me to get to it from the engine by removing the intake manifold than to go from the bottom due to the diff and other extras down there. I took off the manifold, replaced the starter, while I'm there...

    Hey guys. New to the forum, not new to BMW's. I have a 320i Touring with the 2.2L motor. I have the opportunity to grab the full intake off of a 325ci. So I'm wondering if there are any sizes differences in the 2 manifolds and/or throttle bodies? If there are, i'm definitely not expecting...

    I needed to remove the cylinder head and was having trouble removing the exhaust manifold the way the Bentley manual described, so I was able to remove the head with the exhaust manifold still bolted on. You need to be pretty strong to lift the whole thing out at the awkward position you're...

    Hey guys, would it be worth it to remove my intake manifold during the winter? I have a coolant leak right under it, and Im pretty certain its coming from the heater hoses. I already have the o rings for the hoses, but I still need to order the manifold gasket. How many hours approx. did it take...

    Before anything, I did try searching for a bit before posting this. Car is a 2002 325xi sedan I had my headgasket let go on me yesterday, and the car is currently in the shop. As long as the head bolts don't strip in the block and the head is not cracked we will just resurface the head and be...

    I removed my swirl flaps and cleaned out my intake manifold yesterday (thread @bimmerforums - http://www.bimmerforums.co.uk/forum/f18/2003-e46-320d-swirl-flap-removal-intake-cleaning-t277393/#post1838737), and after putting everything back together the car started beautifully. Before it...

    Hey everyone, does anyone have a 330i,xi or 328i header laying around where they could take some detailed pictures about the measurments of the flange? In the next coming months I will be peicing together a turbo setup on my 330xi and I want to make a upward facing turbo mani that will be placed...

    Hey Guys, So I'm in the proccess of putting in my new headers. I wanted to it right so I got all new gaskets. However all threads tell you to buy more studs for the new headers, but my gaskets stagger the holes for the original manifolds. Should I drill the extra holes. If the orignal manifold...

    Hey guys, I have been working on this project for the last month getting all of the pieces together to make it drivable: -OEM Manifold -K&N Air Filter -Vacuum Line to Brakes -Alpha N tune -IAT Senor My goal for this manifold was to make it the induction noise of the car LOUD. The videos...

    I noticed the rattle sound while sitting at stop lights. It sounded like a loose heat shield but I popped the hood and noticed it was coming from the intake manifold. It only happens after the car has warmed up for a few minutes and while its in drive. No noise at all in park or neutral. I've...

    So I just got my headers in the mail yesterday from Trader-NAS via Ebay and I'm really looking forward to getting them installed on my car. I'm not going to be installing them myself since I'm too busy with work for the next couple months, but I still want to make sure that I get the...
