Default How to replace valve seals?

i have been doing some research as to why my 94 4cylinder ranger smokes in the morning or when cold, and eats through oil really fast. After reading some other posts i think i have pin pointed the problem to leaking valve seals, (ps the motor leaks oil from the very rear near the firewall),

how do i go about replaceing them i know the parts are cheap and i need compressed air to keep the valve stem from falling back into the cylinder, and have an accurate torque wrench, other than that i dont know where to begin

anyone out there have experience doing a valve seal repair job?

You'll need a valve spring compressor, and you'll need to remove the head, the seal is a simple cap, but you'll need to remove the spring to get at it. Use the spring compressor to compress the spring, then remove the spring retainers from the valve, then slowly release the spring compressor and take the spring out. The seal is sitting on the bottom of the valve, just slide it off and put a new one on and do everything in reverse to put it back together. Its not hard, only hard part is getting those pesky retainers back in right.

Heres some pictures to help you out, not a ranger but close enough
