Have a OM602 non turbo engine, blown headgasket. Did take the head in to a new to me machine shop, to have it checked out.
Did get a estimate on about $200.
Got it back today, $590!


Two problems, the precambers sticks out 8.9 – 9.0 mm instead of max 8.1mm according to WIS.
And the headsurface have 3 – 7 mm scratches from the machining tool, you see it all over the head and they are deep enough to that I can feel them with my nail.
Will the piston hit the precambers?
Will the headgasket seal in the long run?

I would demand they purchase a new head.I would threaten to call the cops,stating you were robbed of money.Two hit them with the online Better Business Buera

No...

Not the best picture

There are different sized Sealing Rings that go between the Prechambers and the Cylinder head so that you adjust the amount or protrusion on the Prechambers.

I am not sure what passes for a good machining job these days. This is a pic of a Gas Enigne Head I am working on. This is the way it came from the Chevy Factory.
