Hey foxbodymike,Why are you replacing lifters?
Noobz, good to hear from you. You have commented on my other posts. I have found your comments quite helpful.The "tick" can be an exhaust leak or even your leaky lower.
Regardless, you cannot tell by looking at them, whether a lifter is good or bad. Replace one them replace them all. Ensure you put the push rods back in their original positions and orientation.
Are your rockers stud mount or pedestal?
Hey Mikestang,IMO, first throw a can of MMO in the oil and run it for a few hundred miles. See if that frees up the sticky lifter.

As far as my RRs being stud or pedestal -I'm not sure because I have not opened the engine up yet. I'm assuming that I will find 1.7 RRs, but I could be surprised. If they are 1.7 RRs, what orientation do they most often come in?
As far as an intake tick, I never thought of that, but can an intake tick sound exactly like a lifter tick? And, yes, I will not try to replace 1 lifter. I like doing jobs once.
As far as an exhaust leak goes this sounds different to me -although I could be wrong.
As far as the pushrods go I have a box in which I will punch holes that will serve to hold the pushrods in their respective positions. Although, I'm wondering if I should just buy new pushrods. These may be 18 years old. How long does the typical pushrod last?
You can get RRs in either mount so there's no telling till you get the valve covvers off.
If the "tick" goes away after the oil is warmed up then it's likely NOT the gasket leak. If the "tick" stays constant, you can't 100% rule out lifters but it's not often I find hyd lifters for these motor that are completely flat (although it has happened and is usually accompanied by a fair amount of engine sludge).
This is interesting. So, the tick starts after a few minutes of driving from cold and it remains until I stop driving. The tick seems to increase in volume a bit as the engine warms up. Thoughts?
My thought is that it doesn't sound to me like a lifter. If you've got good oil pressure then generally the lifter will tick when cold and fade away as the oil warms up. Could be that you have maladjusted stud mount rockers or cone shaped push-rod ends.
Another theory is that if the rockers are stud mount, that whomever installed them, installed them on the loose side. Nothing wrong with that. Particularly if you're running boost. If this is the case, then it shouldn't sound like one weak lifter. Should sound like a damned sewing machine (lots of ticks).
Buy or borrow a mechanic's stethoscope. That should help you pin down the culptrit.
Thank you Noobz. That sounds rather pedestrian. I'm releived. So, I'm back to my original (sort of) question. Would it be beneficial for me to upload pics & comments during my trek into my new to me engine (regardless of the issue)? I'm hoping to be helpful to someone out there and get feedback as I go.It's not that tough... take the stethoscope and place it directly on the metal near suspected areas (valve cover, rear of lower intake, header flange), and where ever you place it that the tick is at it's the loudest is the area with the problem.
It should even be able to get you to the exact lifter/rocker that bad or out of adjustment, if that's in fact what the problem is.
