valve drop hi, i have a question for ya, beside to take all plugs out and rotate the crank bolt. is there any more ideas on this? its one of the intake ones, and the back driver side. any info. would be great besides pulling the head. thanks mike
If the valve tip is still in the guide I would get a strong magnet on the tip and if you cannot pull it up with that alone you might be able to carefull turn the engine until it bumps the head of the valve to help it up the guide.
good luck.

also try to use an airhold to fill eeh cylinder up with air and pop it back up...this will only work if the valve hasnt dropped completely into the cylinder
Its my understanding that the dropped valve will hit the cylinder wall before the stem falls all the way out of the valve guide. That being the case, youre on the right track, slowly rotate the crank till the piston starts to push up on the valve, you may need to rock back and fourth on the way up so the valvestem doesnt bind up crooked. Removing spark plugs will make it easier to spin the motor, but probably not necessary. I dont know what stage of undress your motor is in, ut you may not want to get to the pasky #8 plug. Also, I dont know if a pen magnet would be strong enough as mentioned above, but it couldnt hurt to try.
