Take some pics! I assume the PCV was easy peasy?
The 2UZ has a reputation for slowly backing out the plugs. Were they all in there snug or did some feel quite loose?
PCV is right on top at the front of the engine. Hose pulled off easily, and the PCV was easy to access with a 23mm (IIRC?) deep socket. Only annoyance was the foam insulation wrapped around the PCV. I tore it a bit when pulling it aside. The PCV is plastic and is not in there very tight at all, unlike the metal PCV on the 4.7. Basically, cheap and super easy to change it, and I'd recommend everyone change it out regularly.
I'll probably make a video for the valve cover job. Plugs were in there good and tight.
. Step two: Shake the truck.....We were bouncing the truck trying to isolate where the creaking was coming from. Dad put his hand on the lower part of the shock and could feel the creaking we were hearing. On the advice of Brian at ARB I blew out the fitting at the bottom with compressed air. This had a noticeable effect on the creaking. But it returned in about 2 days. In the end ARB warrantied both of the front shocks.
