Literally for the 10th time no. All warranties died when HPF closed, that includes mine on my brand new motor from 3 months ago.

Vanos bolt backed out and a piece broke off, then worked it's way down into the oil pan. Evil things happened, scored the cylinder wall. Happened sitting at a traffic light. This is the second time in 7 years that this has happened, just had it serviced by a local shop 3 days before.

It's not uncommon at all, there has been several members on here where that has happened. Mine pissses me off even more, I had the bolts thread locked in. After the whole Vegas fried valves, they swapped heads and the car was up running in days. But I never thought about thread locking the damn bolts on the new head. In fact I think Rob B stage 2 had one back all they way out and make intact to the oil pan.
There are ton's of youtube videos on this bolt failure issue.

Ill look at it tonight. And lock tight is not necessary. Its all about extreme precision of the tq of each bolt. But the inner cam gear bolts cannot just back out as the spring washer and plate are in the way. They can all come loose and causing noise and eventually shear off. So your talking about the hub bolts? Those can back out

This has to be installation error, right? I've worked on a handful of 100k+ S54's, which have never been apart, and they have never had this happen.... Definitely a small sample, but, what? This can't be common...

Yeah, this is more on par with what I have heard.

Look at this diagram.

http://www.realoem.com/bmw/showparts...04&hg=11&fg=25

Its actually in the wrong order. number 3 goes inbetween the hub and cam gears. the upper right parts of number 3 go flush against the cam gear bolts. making it so they have no where to go, to not just back out, exp one at a time. they can get all loose but this is only cuz of whoever installed the damn things in the first place, last I remember all s54's were hand built. and lock tight would only do good if the cam holes were sprayed with brake clean and dried.

but anyways I understand what happened and that does suck, but its not cuz of no lock tight it was just whoever did it fcked up.

Or it never happened to begin with.

PS: Thought the first failure at MFest in 2011 was due to a cam sensor.

LOL more crap coming out of your mouth, motor did not fail at MFest the valves did! I am not the first person to have a bolt back out. Ask evil twin rob, I'm sure he was the other one. Your constantly trying to start crap, maybe you should focus on your shop with John and get the turbo E92 M3 out the door. Or maybe we could talk about the fact that almost EVERY single proefi customer has suddenly sold their cars after going proefi. Not trying to start stuff, but tired of the stupid attacks.

OEM from head BMW, Vanos was not touched. Rob and I both have had this issue, I'm sure it was Rob. The bolt was intact and in the oil pan.

The cam gear bolts can come out...there was a revision made to the bolts iirc. Common upgrade done...they are only torqued to 14nm.

Are you serious thats a little more than finger tight isn't it?? I suppose if there was lock tight done it would not have been a problem. Who knows it could have come from HPF or even BMW messed up. Not a big deal now, over with and done.

Re: Does HPF owe you MONEY, PARTS, or LABOR .. What can WE do ?

Yea its well documented as the bolts are superseded by New pn numbers off of the z4 s54 motor. BMW I'm sure is well aware of this and everyone should check their sprockets for play when adjusting their valves. Please let's stop calling each other liars and end the bickering as this thread is going off topic. If you are not a current customer needing help please stay off this thread as you are just polluting it and making harder for customers needing help again an outlet for people who need support from the few people that are left to assist them. Thanks. I'll clean this up (seperate) later so til then plead stay on topic.

Well, for some people 50ftlb may be finger tight. But yes, 14NM is not very tight - but that's the torque a ton of the top end nuts and bolts are torqued to and it works just fine, usually. The M5X cam bolts are all 14-20NM IIRC.

Didn't know where to post this since the HPF parts thread is closed so I'll post here, is HPF really gone for good? I'm hearing about HPF being bought out by someone else.. will it still be called Horsepowerfreaks? What exactly is the deal? How long is this secret going to take until it surfaces? Can someone please fill me in because I'm confused...
