So when it lines up like this the valve is hitting the piston..

But when i put it like this then looks like everithing is ok...1 cil fiering 6 cil on overlap..On the first picture when i checked the cam the 6 cil was not on overlap but the 1 cil had closed valves...strange...Allso when i removed the chain gear from the cam i see that there are nubers writen on cam...it writes 32 cam with golden letters...What are your thinking about this?

Can you post pic whole crank gear ?
And part # of timing chain set ?

Good morning profesor...

The crank gear had 3 keyholls it had letters A...letter R...and two 0 marks

Looks like its a Cloyes 3110 adjustable timing chain set

Might be a silly question but are you sure you're on the correct stroke in relation to crank/cam timing? Could be on compression for the crank and intake on the cam or vice versa??

Could be...maybe a older version...the cam had writings in golden letters under the gear it wrote 32 cam

The timing chain is installed correctly for 0 advance.

Im no expert but now when two 0 marks meet my 6 cil is fiering(closed both valves) and my 1 cil is in overlap

One thing that most people don't realize is that when you line up the dots on a timing chain, it is not cyl #1 at tdc, it is #6. That is why distributors get installed 180 deg off so often. Cylinder #1 tdc is when both dots are at the 12 o'clock position
