Joey the VNT boosted 205!

Tore this apart from Tom a minute ago as wanted to see what had gone wrong.

Was a bit of an odd one as from outside had appeared to drop a cup, or at least the noise it was making suggested so...

However this isnt what I found!

So put the thing in the workshop, sadly back to using the workshop entrance again as another car is over the pit ( Darrens DT they ask??!! )



Forgot how easy working on XUD's is!








So after pulling the head, there was an immediate problem, totally incomplete combustion on pot 2, how ever pre cup intact, but after instantly noticing an extra shiny bore, and shiny head face, it became obvious the problem wasnt up top, and we have a bottom end failure. Piston has been slapping the head. So seems its shat a big end bearing, and wrecked wrist pin.

No idea on cause not stripped any further this evening, but would predict bending the rod / wrecking the big end shells, or possibly bent the rod, which shortens it up and drops the oil squirter from my previous experiance, which could have then caused a wrist pin failure..either way, bottom end is going to have to come apart, and its bent a valve, looking on the bright side, the block is still in one piece, so hopefully keep things cheap for tom and build up another motor in the same block.

They just dont like big power hikes on stockish internals
