Sixteen bent valves. Apparently I missed a shift, floated all the exhaust valves, and they all bent simultaneously.
Suggestions on where to find a reman cylinder head OR the correct Viggen exhaust valves at a great price for my local, trusted, head rebuilder (A & A Auto Machine) to install? eEuroparts does not list the Viggen exhaust valves.
Alternatively, Goldwing has a 2000 model Viggen long block (no turbo) with 31k on it for $3000 shipped. I could drop that in myself in about twenty hours.

The technician says there's no compression. The engine cranks like there's no compression, but the cams & timing chain rotate when the engine cranks and the pistons go up and down.
How could the engine have no compression without having broken rods or dropped valves or burned pistons all of which would give external clues - noises, smoking, coolant loss, etc?
My 66k Viggen's engine quit at 80 mph and, when trying to restart, gave the customary sewing machine noise when cranking. The accessory belt rotated and the engine made no rude noises and did not leave any smoke or debris on the road. These are classic symptoms of a broken timing chain. But the dealer says the cams are rotating.
Any suggestions?
Andy In Friendswood.
