Crank gear may have spun!!!
As some would know i have been having probloms with cam timing and decided to pull the PTO and check the crank gear has not slipped. Is there any way te check this without pulling the fly wheel of as i have no spare bolts ? they have only been on for 2 hrs run time so could i re use or would i need new ones??

Flywheel bolts are a one time use only I think!

you need to pull the mag to see if the gear spun. once the mag is off lock the crank with the oem lock tool and see where your gear marks land up as. must be 3 oclock and 9 oclock. if they arent you joined my club. in a bad way.

ive watched yourthread and if all else is truly lined up(crank,cam), not slipping(SCer), i'm wondering if its not rings/valves intake manifold(doubtfull) sealing properly.... not that the people/you dont know what your doing but its possible someone made a mistake somewhere. hell that may not even be the case but it will be interesting to see what really is the problem! i wish the best of luck to ya and hope you find it soon
thats why i like the forum... plenty of people to learn from

This thing is doing my head in for sure!!! Iam starting to look at anything that could make it run so off !! I am going to look at valve install height next. I had new ferrea valves and Riva springs installed and was thinking seats cut too deep keeping the valves open slightly at higher rpm!!! its a long shot but i will check this once i find max allowed install height for these engines. IS just another thing can eliminate!!!

FWIW the Ferrea valves for my 2005 engine were approximately 20 thousandths longer than stock. My machinist noticed this and tipped them until they were identical ... not sure if this is enough to cause issues or if it is your issue at all, but thought I would throw it out there. This was also documented in a thread I posted a couple years ago.
