Thumbs down Lifter noise.............ugly story.

I have a 98 F150 with 4.2 (97K miles) that developed a severe case of noisy lifters. Went to Ford where I was told I needed new lifters, so I bought new lifters and just changed all 12.
Started motor and low and behold , still same noise.
I have and had plenty of oil pressure, so I am clueless what the problem could still be.

Any help would be greatly appreciated. Please post here or email me.

Thx, Rob

Hey Rob,

Just a thought, but just 'cause you got pressure to the sending unit, doesn't mean you got pressure at the lifter's. Was it clean inside when you replaced them? If not it could be a blocked oil passage. How about a bent pushrod, bad rocker arm, or just sometimes a bad injector or injectors can make very annoying sound right in the valley area and be hard to pinpont. Worst case it could be piston slap or a wrist pin rattling around, eithr way very bad!!
