Hi everybody.

I've rebuild my engine after the chain breakdown.

Two days after the engine went down again, a cracked valve-guide, that was cracked, the dealer didn't change it, You can imagine how happy I was when discovering that my dealer didn't change all the valve-guides.

The piston has a valve-mark on its top, but no damage.
valve spring lifter broken. New head gasket. two days of additional work.

The engine is like new now, but still have a disturbing noise, it seems to me that's from the intake manifold, I changed the manifold gasket, now result...

Where this noise can be from ??

thanks 4 your help.
