I think I've got the dreaded lifter tick on my Ranger 4.0 OHV... 150k on it.... It's due. Symptoms: Ticking... worse at idle, gets a bit better if you up the RPMs, but is still very evident when accelerating. It doesn't sound bad enough to be a rod knock... sounds like its coming from the top end too. Get's louder after an oil change, gets marginally quieter with mileage after an oil change. Near the end of an oil change (i.e. near 3k miles) the oil pressure sits around the first leg of the M in NORMAL, but right after one, it fluctuates between the left edge of the O and right of the R... When I accelerate hard, it seems to come up, and at cruising speeds, it doesn't seem to fluctuate at all. I suspect this all leads me to the lifter(s). Yay? Nay?
I've found conflicting reports on whether or not the heads must be pulled to correct it...

The question is: Do I or Don't I have to pull the heads to replace them? It's a daily driver, so I just want to make it mechanically sound again...
Also, what damage can occur if I drive it 'til it breaks? Should I be proactive about this one?
Please Help...
Thanx
