Engine misfires are detected by small unexpected changes in the crankshaft rotation speed.

oook. that doesn't sound too good mate

How much are we talking about here for changing the supportive timing mechanism aprox? Excluding the engine drop work and labor... how much would it be for a NEW chain, the variocam tensioners, external chain tensioners, green caps, and other related blah stuff...sealant etc?

Just about 1k? 2k? less more?

What is the firing order? Thanks

1-6-2-4-3-5 Unless severe, cam timing issues typically do not cause misfires, we have seen cars as far out as 8-9 degrees that were otherwise running fine.
