SignUp Now!why is there a bent valve in the cyl head pic?
Rods 5 & 6 are the last oil reqirements in the turbo v6 and yet they were not the source of the problem.If the engine was not primed properly with all else being equal wouldn't you expect to see bearing wear at #6 rod bearing rather than #4?? The 3 & 4 rods bulkhead gallery supply to the crank main is separate and yet I didn't here a lot of whining about bearing destruction on #3 rod bearing.Everyone makes mistakes from time to time and thats ok.How we deal with them shows our metal.I would not be inclined to have any work done at the shop in this thread unless they can represent for themselves more credibly than they have.Just for the record I too have no witness marks around or in the slot of my oil pump drive impeller and my engine runs fine.Does the build sheet furnished with the engine reflect the bearing clearances?
A build sheet means they stand behind their work.The lack of a build sheet gives the builder the means to side step their ownership of mistakes (which we all make).When a very prestigious shop used to do work for me we always had a build sheet showing the clearances and the math to support those numbers.This particular shop has lost a potential customer if they won't stand behind their work by furnishing a build sheet.

What a load of crap. I thought Weber racing was a reputable builder. Geuss not.

I agree, in post 114 that valve does not seem to be seated properly.

That valve is bent. Blow that pic up 200% and you can see it's clearly open on one side. Those were the OP heads. How did that happen?
I am not an expert in engine building and have no reason for the failure. I don't know either party. Here is my take on this. Before coming to the board with this the OP should have contacted the engine builder, brought it to them and watched while it was disassembled so everyone concerned would see the issues. Everyone seems to want to point fingers without any facts. I don't blame Weber for not posting back, they are dammed if they do or don't. Each party seems to have it's story and the truth probably lies somewhere in the middle. The engine builder should have a complete build sheet with everything they did and the specs they set. Everything should varifiable that way. The tricky part is the OP also worked on the engine and started it and drove it. For others just be aware even the best can mess up and not everyone knows how to start a rebuilt engine. Either way this situation sucks.
Well, I would have spent the time to go to watch it be opened up, that is why I would use a local builder.
They would not open it with me there.
Bill, I am going to piss off somebody I know...
I can tell you that if Brian doesn't want to talk to you, you don't get him on the phone...
I am tried of asking for a phone call back. I guess this is a good a place as any to put as I am sure Brian will see this...
Yea I am pissed...
I am tired of a few vendors up here thinking they can skate by without paying... Maybe this will serve as NOTICE to all.... If you owe TurboBuick.com get with me soon, you know who you are.....
