Vulcan engine block replaced; misfire..??
Hey guys.. need some help. 2001 3.0 vulcan engine.. blew the rod. so replaced the bottom block with a good used block, and now it has a misfire on cyl. 1.I did the compression test,.. and number one shows 60 psi.. or so leak down test,.. left the tester on the cyl., for 10 minutes or so, and holds steady.. no leaks on the cyl. 1.holding 60 psi.. the head gasket seems good,.. no exhaust smell on the coolant,.. or overheating,.. etc... the block I'd put in,.. had been tested with liquid on the cylinders.// before the install. had been good.no leaks.. quite confused.. what to do next,..of course it shows misfire on the cel,.. on cyl 1.. your inputs will be appreciated.. thanks.. jc..
