Re: Replacing valve seals with head on (quiksheit)
here is the rope trick. i did this since the air compressor thing was way too exp imo.
remove spark plugs
pick a cylinder you want to work on. set the crank off tdc
stuff the rope through the spark plug hole - you can use a long screwdriver or a wooden stick if you are afraid of damaging the threads.
turn the crank back towards tdc - you will feel the crank stop turning, if not you didnt put in enough rope.
now the valves are safe from falling in
do whatever it is you need to do - replacing the valvesprings, retainers, etc.
turn the crank off tdc, pull the rope out
repeat process for the remaining cyls
