Well, we finished the a6/z6 mini-me tonight and it started (on the second try-timing was off by 180). Once the car was started and running there was immediatly a clicking noise from the head. Any ideas what this could be? The video is up, don't mind the car almost dying towards the end, i was just holding the distributor in place and i accidentally turned it a little bit. It is a shitty vid, but you get the point.

was the block good befor u started?
is it a tick or like bang like a hamer hiting a hamer.
could be a spune rod or valve lash

 

Sounded like a regular 10 year old engine's tick, just 10x louder. Yes the block was good before the mini-me. The head was just freshly rebuilt.

 

probably needed some Valve adjustment.

 

Should have said, rebuilt by a machine shop to OEM specs.

 

valve chatter

 

did you adjust your valves?

 

nope, didn't think i needed to. The valves were "set" by the machine shop.

 

possibly the bearings. pop the oil pan and see if there is any metal shavings from the bearings. Or take apart the cap for the crank and see if you crank is fucked or not

 

everything in the block is fine. This noise is definately in the head.
