Pulling the exhaust cam is very easy and worth it if you have lots of valves out of spec like we did.

The last valve job I did I pulled the intake cams, twice. Was installing performance cams. They went back in the shed after the old engine blew though.

The only time pulling the intake cams is even close to being economical for time is if you are also doing the timing belt, in which that particular case I was. It made swapping shims very easy.

Great video as I haven't had to adjust valves on these engines yet. Good grief in the amount of time and patience needed to get the project done.

Sure alot more complicated then the 22R engine when I you needed was the filler gauge screw driver and wrench.

It was great to see his engine compression come back though. That's rewarding and by doing so gained more hp and torque back..
