I've been working hard to get the z tuned and running well but couldnt seem to get any power out of it. compression test showed #3 cyl @ 0#. Sure enough, rocker fell off its perch and rocker guide(lash pad) is MIA. the valve spring/retainer is almost a centimeter lower than the rest of them which leades me to believe that I have a bent valve. I hammered on the valve and it wouldnt return to the fully 'up' position. Any recommendations on how I should go about fixing this? I would be willing to use someones used valve/retainer/lash pad/rocker arm if someone had an extra they would sell me. It just has to be in OK condition. I am finding it hard to find replacement parts around here. thanks.

I just disassembled a N47 head and have all the rockers, springs, etc. I'm over in Portsmouth about 28 miles away. You're welcome to come over and grab what you need. I'll be around most of the weekend. E-mail at mark4460@cox.net if you're interested.

Thanks Mark! Let me know if I can ever return the favor!

Just got the head off. Turns out #3 intake valve seat fell out and valve wasnt seating, causing the rocker arm to fall off its...rocker. I hope the dealership carries these... Is this something I can do myself? I own a freezer... and I can use the old valve to drive the seat in. Any advice is appreciated.

I think Aerodyne machine shop at the Hampton Roads Airport would be a good choice for the valve seat work.
