02 explorer, pushrod stuck ?

I have a 2002 explorer engine,4.6l, from a test vehicle. it should only have about 9,000 miles on it. The engine is very clean so the mileage should be correct. I had someone put in some crower cams then after the swap he showed me that a push rod on cylindar 6 gets stuck. I dont know if its intake or exhaust at the moment. It will go down but not come back up unless its forced back up. The problem could be that the engine just set for a while with that pushrod left open and its gummed up or rusted in there. This guy who did my cam swap now wants $150 to take it apart and put back togather. I suggested just trying to throw some lubrication in there and if it gets loose then im good to go. He strongly advised against it. What are the chances that all i need to do is just throw some oil in there. I dont want to spend more on this engine. Im debating taking it apart myself because he has the new cams in so hopfully i can reverse engineer it. Im going to start tearing off my cams off the old tbird engine that this explorer is replacing.

Should i just lube it or is that risky that even if it moves free it might lock up one day while im doing 5,000 rpm's?

it's either the valve or the cam follower that you are talking about.

either slightly bent valve or incorrectly installed cam follower?

You mean the pushrod that is surrounded by that big spring? LOL
That would be a valvestem.
I wouldn't pay the guy any more money to work on a modular engine if I were you.

I say he f#cked the cam install and bent you a valve.

Yes, its the valve stem.

I think im going to take my broken tbird motor apart for practice and then do this explorer one. unfortunately i didnt rotate the engine before i gave it to him to do the install. Where can i find the valve spring compressor that works on these engines?
