[QUOTE="Mystic_Cobra, post: 14654118, member: 6398"] A few extra tips that should help others from when I did this... 1. Make sure you have the cylinder full of pressurized air using the leak down tester. I would NOT try this job without a compressor. I pulled the valve core/check valve from the leak down tester (just like in a tire valve) so the compressor was constantly filling the cylinder while the air was leaking past the rings. Yes, this is normal. I put some heavy oil down into each cylinder before I started to minimize the leakage. Not sure if it really helped but I did it. 2. When you are trying to put the keeper in place, I had better luck using a long #2 flat blade screw driver with some thick grease (assembly lube) on the tip instead of the needle nose pliers. The keeper is so light it just sticks to the grease on the tip. Try both ways and see what works for you. 3. Take the rocker arms off before you start. There's a good video on youtube that shows you how to pop the rockers off (and reinstall them) with just a flat blade screw driver. It's pretty easy once you figure it out. No other tools necessary. I just rotate the crank around until that cylinder is at TDC so there's less spring pressure on the rocker. They just about fall out with just a little force when prying on the head casting. 4. Clean work area or spare parts! I lost at least two keepers because those suckers go flying. Luckily I have a spare set of heads so I had spare keepers. Be prepared to go looking for them. Nice writeup! [/QUOTE]
