Hey guys, i'v had a set of NPR b18c5 pistons fitted to my b16b rod to lower the comp for boost. The thing is 3 of the pistons you can rock backward and forward easy but there is one that feels quite stiff. Is this a problem ? You can rock it but it takes a fair bit more effort to do so.

 

idk about you, but an engine moves at a hell of alot more speed and power than I personally can. know what i mean?

 

Yeah i do, but i was thinking it mite cause the piston wear on the front and back if it carnt move freely enouth. You can move it but not a free as the others.

 

it should be fine after you put some oil on it.

 

good thinking, ^. i wasn't trying to come across as an ***. i was just thinking, maybe its just how the pin is sitting or something, idk.
