I had planned on having the motor in the truck this weekend and fired up for the first time....but looks like more time and $$$$ is required.
I planned to pull the push rods, rockers, and valve springs out of my 95 motor..I was disappointed to find that my Delta Cam "hardened" rockers are toast...only about 30K on them and they are worse than any 200K set I have seen....
So now I am contacting Delta. I expect to get no response or a poor one if I do get one. I have had them for a few years, but like I said...less than 30K....most likely going to buy new Sealed Power replacements since they are new castings and have fantastic reviews in the small built 4.0 OHV community.lol....soo more $$$$
I pulled the clutch off the old motor as well...Its not trash, but it shows more wear than I expected and I don't want to put it behind a fresh build...so more $$$$ there. I will go with the same Luk Pro Gold again though, it has been through hell for 40K+
I was inspecting the heads after I painted them so they could be installed...when I noticed a few of the valve seals are not seated all the way or even straight for that matter... No big deal since I need to swap out the valve springs and retainers anyway. This is when I found the bigger issue. The first valve I removed the hardware from slid nice a free in the guide, but the second had a rough spot..
I found a few burrs on the stem right where the seal rides. This will destroy the seal in no time flat. So I ran through all the possibilities in my head about what I had done. This is when I began looking closer at the other head (which I have not removed any hardware from) and I can see a few valves with similar damage to the stems
Now I am thinking about going SS valves and bronze guides since the valves are garbage IMO anyway...so more $$$$
At least the P&P looks good!
I did a little measuring on the springs while everything was apart. Strength appears to to be similar to stock, but they are a larger wire diameter and have one less coil as well as an additional flat coul spring inside. This allows them to go solid at 1" vs the OEM 1.140". They are a little easier on the valves than the 988 Comp springs that most run with the 422 cam (which require machining of the heads). I also found the retainers are shaved down ~.020" to allow for more valve travel.
