Blown VVEL !!!

Megan370z

A few guys already know that I blew my engine at my last Time Attack.
this is some update from my diagnostic .

I towed it back from the dealership last saturday so I started right away to remove everthing in front of the engine to have a full acces to the front .

I removed both cam cover to look at the chain since I suspected a broken or loose chain .
the driver side chain that connect both Intake and exhaust cam was quite loose to compare with the passenger side !
until I compare them side by side , I suspect one of them elongated !

next step was to remove the driver valve cover to see what went wrong in the end where the knocking was comming from in the beginning while the engine was still running porly



Located at piston#6 ,, look alright and wet from the oil... not much sign of any defects.



something is missing there !



humm broken pawl and pin somewhere in the bottom of the engine head.



the wrose where everything went bad from the engine code I got first ... piston#4 VVEl look very dried up and rusted already ,, !!



dried up lobe from a broken VVEL pawl. the rust is already getting there !!! must have been red hot.



the wrose where everything went bad from the engine code I got first ... piston#4 VVEl look very dried up and rusted already ,, !!



I wonder what composition is in the center that melted !
located on piston#2



you can see the dried VVEL camshaft and the broken pawl , VVEL valve from piston #2



side holding pin pawl getting out !!!! ,, VVEL valve from piston #4 , the dried up VVEL is due to an extreme heat generated by the lack or lubrification !



soo after this ... my conclusion would be
do not rev up to 8000 rpm !! and avoid taking corner at 1.35-1.4G
