Volvo Engine head porting / port matching prep work !
Music : Mr oizo and Gaspard Augé "tricyle express" Step two in the project : Gasket matching is a good way to improve the flow in your head (engine heads only) and to avoid the bad turbulences where they are not supposed to be : between parts. It's the first step in your porting job that you should think about ,and do with your brain and hands. The castings patterns are often quite "bad quality" (or i should say the consequence of the application of a mass production process ) and it's the way to start this kind of job.

Volvo 740 valve adjustment
This car and it's and owner are very special to me. Back in the day, they called this car a 7 passenger Ferarri. I remember the funny Volvo TV ad's comparing both cars. It is a 1988 turbo Volvo 740 2.3 liter 4 cylinder with mechanical shim and bucket valve adjustment discs. Very simular to the older 1.6 liter VW water cooled engines like the Rabbit and Scirocco. This Volvo has 272k miles on the clock, 155k miles on a rebuilt engine and rebuilt head without any valve adjustments. I rebuilt the entire engine in 2003. Recently the idle quality became rough and spark plugs started to foul when the two front cylinders valve seat and valve wear absorbed the valve lash clearances to almost nothing. This car belongs to a very special client. She'll never know how many hours I have invested in keeping this turbo Brick going.
