[Vwdiesel] was starting and now a bomb

[The President]

Paul unless you block off the exhaust you will see no gain/ difference in 
pressure between a good cylinder and a duffer. Blocking exhaust would mean 
pressurising on the exhaust stroke creating a 1600 cc footpump... This I'm 
sure could  increase over many strokes but utimately it would need to rise 
to 200psi for a bad ring and 400psi or more for a  perfect cylinder.
Wouldn't like to be standing next to you when the exhaust gave up holding 
that quantity of air at that pressure...

It'll be like those guys who shoot cars into the air with an air cannon.

Do as I suggested before and check for 'priming' fuel starvation. ...Even a 
bad injector would let you start the car and then run lumpy/smokey. But to 
have 4 'fail' I dunno...But you say it runswell when it starts didn't you?
Good luck
Mark
