| | OP low cold, OP normal warm
TBSS LS2. OP was normal 40psi cold/warm. Melling high volume, high pressure pump.
Heard a noise one day, very faint only on light accel 2.2k~ rpm. Did cylinder balance test, it was #6 piston. I pulled pan, polished the crank journal, made sure it specd out right before slapping a new bearing set in for that one rod only.
Took the rest of the caps off to ensure the other bearings were fine. All was good. Replaced motor mounts while I was in there.
Truck runs fine, pulls hard, no noise. But ever since I completed this a month or so ago, my OP has been acting strangely.
Typically, idle and cold, it's around 25psi. Drive it around for a while, at idle it's 40psi. Sometimes I drive it around for a while and it still goes back down to 25psi.
I re-used my pickup tube o-ring as it was only 1 year old.
Think that may be the case here? Kinda weird the only things I touched were rod caps, the one bearing half, and the pickup o-ring that could've affected pressure...
