What is the best way to check the timing on a 2010 MCS? Without opening it up.

Also, is the VANOS sprocket normally replaced? I think I may need to replace the solenoid, anyway.

I am also getting the 2B64 code. I have already replaced the valve cover and the code came back. Should I just take it for a smoke test?

The car is also getting to what I would think are very hot temperatures; nearing 230F. Flushed and changed coolant (50/50 mix) and changed thermostat housing with OEM.

Finally, it is stalling when making slow sharpish turns.

Hopefully, some of you all can help me before I douse the thing with gasoline and put a match to it.

Thanks!

 

Sorry for the somewhat overwhelming post! Haha!

 

There really is no way to check timing without at least taking the cam cover off. If you have the timing tools, you’ll want to remove the cam cover, lock the flywheel, then install the cam tools. If the cam timing is proper, everything will lock down. If the timing is off, you’ll know right away.

2B64 Is a code for unmetered air in the manifold. Check the tube that goes from the back of the cam cover to the manifold. Those are known the age and crack letting air bypass into the manifold. If it wasn’t replaced with the cam cover, then it probably cracked during the swap.

 

I replaced the timing chain and guides. Inthe process, I turned the camshafts to their correct positions, locked the flywheel, and locked the cams down with the required tools.

 

Could you check timing without tools?
When crank is locked the pistons should be level with each other and then you could check that camshaft writings are facing up flat ends of camshafts are parallel with cylinder head edge? Or would that be wrong?

 

That would get you close, but the cams could still be off enough to give you headaches

 

I'll get the timing tool then. Thanks!
