Looking for some help please

2001 ford ranger 3.0 by
200k miles
Dry compression test was low: 90psi
wet test: 120psi
I just replaced all pistons and rings
New lifters and rods
new gaskets
new oil
new coolant
And some other new stuff but I dont think its relevant to my problem

Check engine light only blinks if at idle for a while
seems to run fine other than at idle
there is a ticking noise that sounds like it's coming from the lifter/valve area for cylinder 6, but only happens when at operating temperature and at idle. Goes away when I accelerate in the slightest.

I know the dry and wet test should tell me the rings are the problem but I literally just installed them 3 weeks ago and truck ran great for 2 weeks till now I have this misfire code again. It's just hard for me to believe my rings could go bad this quickly.

 

Update: was just a faulty gasket

 

Glad you figured it out. How did you figure it out? Which gasket?

 

Just started tearing down and saw the rubber gasket between bottom intake manifold and motor was completely torn in half. Knew since I just replaced about everything that I didnt have to go further. Definitely grateful that was all

 

Actually still need help, guess I jumped the gun and thought it was all fixed. Code came back, same symptoms. Please help

 

Well.. I have to ask:
1: New pistons and rings... so I assume you had cylinders reworked?
2: Did you inspect the rockers for wear when replacing the pushrods and lifters?
3: Any work done to the heads other than just cleaned up?
4: What trouble code? Even if CEL doesn't stay lit, there may be a stored code.
Please mention "other new stuff" because it actually could be relevant. It gives a better picture of what you got going on.
