Fact is; with a loose tensioner (NO TENSIONER) it will IDLE LIKE SH$T but it may NOT be off a tooth all.
HIGH RISK, go for the Gusto repair: Pull the plugs, tighten the tensioner and turn it over by hand through the removable cap on the CKP cover. If it turns 720 degrees w/out colliding, hit the starter (Risk is bending the valves). If its still turning, throw a compression gauge on one hole. If the # is good its very likely still "in time" but the loose tensioner caused erratic operation.
LOW RISK repair: Pull the plugs, valve cover, CKP cover. Check the timing by aligning TDC on the firing stroke.
HINDSIGHT says its VERY unlikely the chain can skip over the larger intake & Exhaust gears, MUCH MORE LIKELY to skip over the crank gear with its small diameter. JMO Thus, BOTH cams are out of time. Not just one.
As we know it, there is no proof that it's actually "off a tooth". With no tension to the chain it will be hell to start, idle like crap and be ALL OVER THE MAP RPM WISE. <<Still not proof its off a tooth.
To FIX the timing if its off:
1) Remove the CCT and Loosen the guides as Marty said.
2) From other DOHC engines I've done; the chain doesn't allow the ONE gear to be removed while one remains fixed in place (Its NOT A SNAKE it won't BEND like that). HOWEVER, removing BOTH the intake and exhaust gears together allows you to orientate them correctly.
I love these threads where we discuss for weeks what to do...
