I know this is dated, but wondering if you dug further. That's dead on what mine sounds like and forgiving anyone that's read the entire thread, I've replaced:
Oil Pump Drive Assembly
New Head
New lifters, push-rods, etc.
I'm 100% certain the timing chain needs a reboot (I'm at 285K+ at the moment) and the shop agrees it's piston slap, so I'm looking for a rebuild.
Actually I came here today to see if anyone had good recommends on a rebuild kit?
As the engine mounts need replacing, I'm actually wondering if I should just swap the engine altogether or do the rebuild myself.
Either way, I'm currently leaning toward the CompCam kit for chain, crankshaft and such. Sucks that I already did lifters and whatnot, but I'm more concerned with getting good quality pistons and rings.
Any ideas from the community?
