I’ve had to install a tensioner already activated, it’s still working just fine.
yes, I now remember those spacers are between the sprocket and the harmonic balancer, on the 2.0 LNF only.

 

Forgot to tighten the thermostat housing banjo bolt lol. Bunch of coolant leaked out. But its fine now. I guess it was just the water pump.

 

Forgot this thing...where does it go?

 

If it’s green plastic, the recycling bin, that’s the protective disc from the harmonic balancer seal installed in the front cover

 

#900 shows the shim behind the sprocket, like Oldblue said

Photo of LNF 2.0 timing chain sprocket, now shims

Same engine

 

They're so thin, it doesn't seem like it would make a difference, but...

The slight misalignment of the crankshaft gear could potentially cause premature wear, the smart move would be to put them where they belong.

 

Im sorry but i can't see those pics or they don't enlarge for me to see anything in detail.

is the right place in front or behind the timing sprocket?

 

FireManGeorge gave a link in the other thread. 1 in front and 1 behind.
