Good luck to the OP on getting his car fixed.

I'm genuinely surprised at how many folks here don't know what OFHG is. I am not a car/DIY maintenance person at all, but just being a member of this forum over the years I learned what OFHG is (and no, I have not had it replaced on my car).

I guess you're blind or you never really owned them that long.

Right on the first part. I'm blind. Actually, since I haven't had any oil leak problems with my BMWs, I never paid attention to those posts.

Wrong on the second part. I'm a keep and hold BMW owner. My first was an '88 528e that I bought new. I drove it for 9 years and gave it to my son who kept the 528 another 6 years. I got my '97 540i and handed it down to my son after 9 years. I've had my current BMW, an F30 for 8 years and plan to keep it indefinitely. No oil leaks ever on any of them.

I have them serviced on schedule and I drive them pretty gently.

Your experience is quite exceptional-

...and that's not all! I had a 2003 540i from 2006 until it crashed in 2012. No oil leaks or major problems in that one either. My wife has a G05 X5 and we are lucky with that one too. I may be the only one with great luck with several BMWs with lots of miles over lots of years. I feel very fortunate indeed.

I don't pull the coolant flange from the front of the head, and I don't remove the intake manifold. Edit: I also clamp the hose off the heat exchanger so I don't have to drain coolant or oil.

The front bolt gets loosened with a flat E10 wrench (Stahlwille) or alternatively a short E10 1/4 socket (Stahlwille) and a 1/4 breaker bar. Once it's loose, I use an 8mm ratcheting wrench (Craftsman [Gearwrench]) to extract the bolt. If I owned a ratcheting E10, I might try that, but alas... Also note that the Snap-On E8/E10 combo wrench is both too long and too angled to fit.

The middle bolt is a straight R/R using a convention E10 socket in either 1/4 or 3/8 drive.

The rear bolt gets removed using the 1/4 swivel E10 (Snap-On) [now also available as CTA 2476] by going between the 1st and 2nd runners on the intake with a long 1/4 locking extension.

Everything gets torqued back to spec with a Stahlwille 730/5 - 725QR



Don't mind the fact that I also had the valve cover off this N52 to replace the eccentric shaft sensor for the Vanos.

My 328i has almost 260,000kms on. I have done this job twice already and it looks like I have a leak again. None of the jobs lasted more than 2 years. What gives? I am wondering if there is a go-to brand of gasket. Any advice? Oh, here in Calgary the BMW dealership wants 82 CAD for the gasket. Mind blowing.

OK, on my two attempts I was not able to torque the front lower bolt to spec. I have a socket that is 25mm long and the Mickey Mouse flange will not allow a torque wrench to fit. A shallow socket is on the way so I am hoping I can torque the bolt this time. Also, the bolt under the exhaust manifold can only be torqued with a kinked swivel. Who knows what torque you get even if you set your torque wrench right.
