I'm not sure why you created this account to post on my thread, but get lost.

 

The assessment of the heads is done. A bunch of valves are bent, the valve seals that were used are loose, which is why they "fell off" and and the wrong lash caps were sent.

I spoke with John yesterday and we had a great conversation. He could not have been better to deal with throughout the conversation. The heads and pistons are being sent to him today and he is going to repair all the damage. I know that when the work was done it was a "transitional" period when John was leaving EvoMS.... "I believe" for reasons such as this. I'm looking forward to getting the parts back and getting the engine back together.

As always, I'm a straight shooter. I post honest experiences. Some people get offended because of personal friendships, but that's the way it is.

 

 

sounds like he pursued this privately for a while and got nowhere until he aired it out.


vr6tee - hope u get it straightened out. check piston to valve clearance next time too.

 

That is great you were able to get things worked out with the builder. It sounds like he is doing exactly what he should be doing for you.

It is a shame that you had to go through all of this, but it is good that you have a path to solve it now. I know that not everyone has that experience with vendors (not just Porsche, but any vendor) and it is always great to hear that a reputable vendor will do the right thing.

Good luck with everything!

Excellent! Glad it's working out. Sadly, in today's age, you can't post anything negative about an experience w/out everyone coming out of the woodwork to cheerlead. This should be a good example. Air you grievances, and in the end it all works out. Sadly, today, people don't like dissenting opinions and challenge it or delete them/block them.

 

Congrats! I had no doubt it would be cleared up. Makes me wish I had more cars to send to John.

 

Same here I think you will find that working with John directly you will be all set. Whatever happened and whomever was in charge at that time, he will sort you out no question. I even chatted with John about this, he is a sincere hard working gent. Hope to see you posting some good times soon J! I agree, threads like this and the power of the forum can shed light, help things along and contribute to the community.

 

. Then you have zero cred when it comes to this particular subject.

 

You're funny. This has NOTHING to do with a BIG HP Mezger build as stated prior. This is FUNDAMENTAL, rudimentary work. Again whether it's a Mezger or lawn mower engine, the process of clearances is exactly the same.

How much experience do you have, you never answered? You PAY people to do your work, no? I've only seen pics of OTHER people working on your engine/car...


Edit: Again I originally LOL, because your post was that "these things are never right the first time",...... Um, the guys engine needs to be rebuilt, this isn't the same as fasteners coming loose and needed to be re-torqued, this is a BIG failure from an issue that shouldn't ever have happened. No reason to come down on me. This guy must be on your payroll.

 

We aren't talking about 1500hp Lawn mower engines. We aren't even talking about stock Mezgers (which have proven to be solid stock motors). No, I don't build engines. But I've got extensive experience with BIG hp Mezger motors and there is no cookie cutter solution yet to the process. So if you think there is one, simple, easy, fool proof way to build a 1000+ Mezger, you're simply naive. The real world doesn't work like that.

I've used Protomotive, Evoms and now John Bray. They are all good builders, but they've all built engines that break right off the bat. It's no knock on them, it's an ever evolving process until there is a solid solution.

 

We're still talking fundamentals here was/is my point. You're missing that. This issue is not exclusive to the Mezger. Measuring clearances is engine building 101. Sure mistakes happen and we've all broken ****, but to originally dismiss it as, "they all don't work right at first", is simply wrong and misleading, that's all. Hence my analogy. This problem isn't a Mezger problem, something slipped through the cracks. Plenty of Porsche motors are built 1x only. HP had nothing to do with this build as the car didn't work right. Boost and HP numbers are 3rd party to these issues. Big HP or stock Mezger the same thing would have happened here. This again has nothing to do w/ HP.

The sad problem today is that god forbid someone has a differing/dissenting opinion on the internet, guys like you come along, out of the woodwork, to jump on the bandwagon cause you obviously have worked with Mr. Bray before.

Bottom line, OP paid someone to clearance the motor and it wasn't done properly at all and thus is broken. Again either 50hp or 1,500 HP makes no difference as the outcome would've been the same.

 

gents take it easy....

 

 

I know that there are differing viewpoints and experiences that people have regarding any work done, whether engine, suspension or body work.

While a view that is obviously outrageous may need to be admonished, I cringe when I see a back and forth that gets too confrontational. In my view, everything that has been posted here has merit and informs the members of this forum, even if you might not agree with every statement made.

The only thing I wish for (on this and other forums I am a member of) is that a certain level of civility prevails. There is nothing wrong with a good back and forth, but sometimes the commentary strays into what I would consider unacceptable. While this thread hasn't crossed that line completely, it has come close in a couple of posts. So if you would, think about what you are writing and if you wouldn't want it said to you, you probably shouldn't post it.

I can see where extreme build outs can run into issues, I can also see that if you are paying top dollar for work it would be reasonable to expect that the work would be done in a way that results in success. When I commissioned head and block work on my S6 (forged rods, oversize valves, cams, high rate valve springs) I expected and received well done work that when I assembled together (along with a LWFW, Stage 2 clutch, better EM and some other items) worked right the first time. Now a turbo I5 AAN engine is a much different beast than a flat six, but I agree the principles of good workmanship should be able to be applied across the board. I know guys that have gone to huge turbos and the various bits that are necessary for them (FP, Injectors, EM, exhaust, ECU coding, etc) have run into issues, even to the point of using such software changes that led to them blowing up their engines trying to get to the highest HP they can. It happens.

But in my opinion, the stuff the OP has posted here is much different than that and in no way should be brushed off as expected in a high end build. These mistakes are pretty much unexpected and should never have happened, period.

At the same time, I understand the comments about expecting issues with high end builds, however I think these issues would always be considered unexpected, but again, that's my opinion and the last thing I am going to do is attack someone for their opinion. I am just going to state mine and let everyone reading the forum digest all the information and make their own decisions. There is nothing better than getting as much information from as many sources as possible so you can make the best decision you can make.

The best thing about this thread is that the builder is going to do right by the OP, and that is the most important thing. And by doing so, the builder will increase his reputation and secure future business, again the right thing any vendor should do.
