    I've been having issues with my boosted setup for a while and am still in the process of figuring out exactly where the problem lies. It's an AA stage 1 setup. Moderate throttle is causing bucking. My inclination is that there's a vacuum/boost leak somewhere. At any rate, that's not really what...

    Hey, I've got an issue with my M52TUB25 on my 323i. A few months ago I started feeling and hearing a kind of grinding noise coming from the front of the valve cover, near the VANOS. After doing some research, I decided to redo the VANOS with a seal and anti-rattle ring kit, that didn't fix the...

    Be aware of this crap! They said it fits. It doesn't. The semicircles are absent up front and fit is extremely tight. I had OEM parts coming but absolutely needed the car tomorrow since my primary workhorse car needs a wheel bearing so got the fel pro from AutoZone. I guess I will have to learn...

    I took my 323i to my mechanic and was told I had a valve cover leak. I was hoping someone could point me in the right direction as to which parts I should purchase to replace the cover and gasket. I understand OEM is always recommended but will after market parts that exceed OEM specifications...

    Hi Guys! Long time member here. Recently completed a full m56 Valve cover swap - including PCV delete. I'm now getting a large amount of positive pressure through the crankcase which is leading to oil leaks around the engine. When removing the Oil fill cap I get the sound of air pushing out...

    Quick question about the valve cover on a 2004 BMW 330ci. My cover was recently damaged at it cracked. I have a new one to replace it but I was wondering if I needed to replace the gasket if I removed the valve cover. The only reason I am hesitated to replace the gasket is because I replaced it...

    My '01 325i is leaking at the valve cover again after about 85k miles since the last one. I've recently moved to NW Arkansas so I don't have an independent mechanic here. I'd do the the vc gasket myself but there's a slight coolant leak again around the water pump and thermo neck and I don't...

    Hi guys, I'm refreshing everything regarding potential vacuum leaks and vanos rebuild but on removing my valve cover and checking for warping i see the plastic valve cover is raised at the front. It's all straight bar the end covering the vanos itself where its lifted between 2mm and 3mm from...

    I was replacing my VCG this past weekend and find the engine cover mount closest to the firewall on my valve cover has broken. My attempts to remove it resulted in the rubber part further coming off. I've attached pictures of the non-broken mount for reference, and the broken one. Any ideas on...

    Hi everyone, Currently I am trying to replace my valve cover gasket because it is leaking. I have removed every one of the vcg bolts except for the far left bolt. It will not budge, and on top of that, it is very difficult to get to. Does anyone have any suggestions?

    So my car has been giving me problems for the past few months, some I have fixed and some are still on the list. I just replaced the fuel filter, alternator, I bought a set of coils and bosh Plat. 4s that I am debating on when I should put in. Before the fuel filter was changed it was throwing...

    My 320i is still leaking oil from the valve cover after two replacements, causing smoke coming into the cabin and out of the engine bay. I figured I may have done something wrong the first time, so I replaced the gasket, all of the rubber grommets on the bolts, and the washers on all of the...

    Hi guys I have an '03 325ci (10/02) with part# 11 12 7 512 839, but I was wondering if I could use an identical looking one with the part# 11 12 7 512 840 instead?

    Hi all, Did a search and couldn't find anything useful. I ordered a new VCG (Elring part 11129070990) for my dad's 2001 330cic, as the present one leaks. When I got to his place and looked through the records from his indy shop, it says the VCG was replaced in April 2012 and again in March...

    I was changing my oil today and notices a lot of oil and road scum buildup on top of my valve cover. After cleaning off the cover I noticed a small 1mm sized hole in the cover above the timing chain. Is there a way I could fix the hole without replacing the whole valve cover?

    A couple weeks ago I replaced the VCG, spark plugs, and rebuilt the Vanos unit. Since then it seems the moderate oil loss my car was suffering has increased. I have a hunch this could be caused by the CCV, but before I start ordering parts and taking on random jobs I thought I'd ask for...

    I cracked my existing valve cover while replacing gasket about 750 miles ago and I'm now replacing it due to minor leakage. Should I install a new VCG or can I re-use the existing one that has only a few miles on it? Thanks. Sent from BimmerApp mobile app

    Okay guys so I had a look under my hood the other day and noticed that my plastic engine cover (is there a real name for this guy?) was cracked. So naturally I ran out to Home Depot and got some sticky stuff to fix it up all nice. Here goes. You can see the crack here where the oil cap screws...
