4.7L: How hard is it to change valve seats?
Going to tackle this oil leak. I have a compressor & my mechanic is going to lend me the adapter to keep the valves from dropping into the engine. He also gave me the part number to compress the spring:

What other special tools should I need and are the rockers easy to remove?
I'm a little concerned about getting toward the back of the engine. Any advise is appreciated.
Thanks

What's the best way to determine that the piston is close to TDC on a 4.7L?

Everything can stay together except you need to take valve covers off, pull spark plugs. Put a wrench on crankshaft so you can turn engine by hand. Pick a cylinder, watch the valves while turning engine over with wrench. Turn engine, watch the exhaust valve close, the intake valve will then start opening....keep going until the intake valve closes, at this point turn engine about half a turn further. This will put the piston close to being up and both valves closed, put the air adapter in and turn on the air, you should now be able to remove springs and change seals.....have fun.

Really, it's not that tough, this is a pretty simple job, few hours you'll be done and happy

Oh yeah I know. Just recently did the heater core. Ordering the tool & valve stem seals. I'll let you know how it goes.

Is this the right one?

Does it matter if I have a small compressor? Do I need a specific PSI?
Also, can I use the cam bolt to turn over the engine & find TDC?
Thanks
