some bad pics of a WBX head

[joop]

Someone brought me his DH engine to make it run better....
All 4 sparkplugs where loose... it had just been serviced...

I just liked to share the pics with you

His wife was behind the wheel

The heads look just like the heads I pulled of my DH engine also.

Maybe detonation damage that.

Maybe detonation damage that.

I do think so also

I think it started here.... steel from the plug melted also...
Plug was @ 4 turns out.
static timing was ok, no other airleaks found so far...

I was a "little" late for work yesterday...... helped with a little tailwind

Cool Joop, a pound (alright, 1 euro) says the dizzy vac pod is the cause especially if it has the double one, theyre always timed wrong.
