I'll get to the timing chain allen key bolts soon. My head gaskets are blown and my engine will overheat due to exhaust gases entering the cooling system. This is the third time the heads are coming off in the life of the engine (145,000 miles). So yes, according to the engine manual, if you remove more than one head they recommend to replace the cylinder liner seals, so I figure it's about time. While I'm down there I'm going to add new Rod and Main Bearings and new "Totalseal" Piston Rings.
