No emission checks on cars over 20 years here in canada, you could put a jet engine in if you so desired.

the ticking is comming from the passenger side valve cover area, its audiable at almost any engine speed,

I do all my own work on cars, but I had to take it to a mechanic for a safety inspection, he said it was defintly cam and lifter noise.

Although its not good news, its pleasing to know that the chain isnt going to snap on the drive home.
