Btw....what is the spec to torque the flywheel to?

150 ft. lbs, how about I send you a Service Manual for your engine? Address below, put in proper format and remind me engine model number and what you want.

OK so exit easy fix No 2
You are now left with valves & cam as it is only happening on one side
If you have an accurate depth gauge , measure the height of the valves and the valve springs,
They should both be the same.
measure the lift again they should both be the same.
Double check these against the right cylinder.

When you are talking about the height of the valves are you referring to the height of the stem sticking through the head? Please explain the lift also.

Thanks!

Walt,

I sent you an email to the above address. Did you receive it?

No, you did understand about putting the address in proper format? I don't use the address in regular form because of spam crawlers harvesting addresses.

The height from the floor of the head to the top of the valve.
If the head has overheated the valve guide can shift in the head
If the cam is worn the valve controlled by it will not move as far as the others.
Same thing happens with a bent pushrod for different reasons ( the rod flexes at the bend ) but that usually only happens at speed.
