12 frozen H lifters in my 72 350
and 1 broken rocker stud i only drove it 1 or 2x a month past 20 yrs, (6000 miles) due to health problems. it is an XE262. it was backfiring out the carb and i thought "wiped cam" but no, frozen lifters. there was never any taps.
So my advice to you guys is to avoid health problems so you can drive more when you are old like me 67.
It is easier than you think to stay healthy! Just avoid fat, oils, butter, dairy, and ice cream
once i cut out the fat i got better. I had no idea that a slim guy like me had to worry about fat. past 20 yrs never more than 134#.

lash?
so where do you guys set the lash when the H lifters are frozen? I set mine at .005"
Started up, ran good, no taps, but not driving as i just ordered a new stud, so just 7 cyl working.
ps iron heads/block

R&R Lifters and clean them
A basic outline
If you have some mechanic abilities, a steady workbench in a clean work area that's Not served by same HVAC as your living area ... and a few standard paperboard egg crates ...
pull each of 16 lifters out and absolutely note exactly which positions they came from, so you can replace each in its discrete position ...
you can depress each lifter's spring-loaded pushrod cup with a drill press or bench vise ... cup retainer / clip prone to flight; don't lose it
disassemble each lifter (retainer clip's prone to flight; don't lose it) and keep as one discrete unit ... then clean parts well with aerosol brake / carburetor cleaner ...
lightly coat / spray parts with oil or WD40 ... reassemble parts (don't lose that retainer clip) ... install ... ensuring each lifter's returned to same bore it came from.

Hi Jackson
if i had 1 froze lifter i'd try to get it apart. maybe soak in carb cleaner, or heat with a torch. BUT once i had a lifter stuck in the bore and i ended up junking the whole engine. froze parts are a PITA.
i did hammer on all 12 and they are SOLID. a pipe dream that all 12 will come apart. maybe 1-11 but not 12

i once put new lifters on a cam with only 1000 miles, and 1 lobe wiped in 50 miles. So i'm not sure it will be a success. Plus my xe262 has been hammered for who knows how long. some may have been solid for years. not good for cam life ........................ not going to play laborous games with it. It will be driven until it wipes. My question is
"How much cold lash to try?"

so you want to adjust them as if they are solid? Use solid lifter specs. If you wipe out those lobes the metal will travel throughout the motor, then you'll have to do a rebuild, and then you'll be able to get new lifters along with everything else.

And no i don't use solid settings. Did this once before and i just adjusted the valves running, to where it liked to run. did not use a feeler gauge. This time i thought i'd give you guys a chance to show me you learned something in the past 20 years. But, so far nobody would try such an outlandish idea
Thanks for the well wishes I had to do my own experiments on that too; DR.s are even more timid.

Am asking for a friend that has hydraulic roller cam/lifters and the car sits WAY too long due to failing transmission...)

Hi Ted
you know what a solid lifter is? 12 are now solid. internals frozen.
i should check my 61 too, have not had the covers off in 25 years. Did set it to zero so i could rev it to 7,000 without floating. could be froze up and i'd not notice. i drive it even less.

The biggest problem is that all that metal from the camshaft is in the oil and the filter isn't going to pick everything up before it circulates in the engine. This will cause damage to pretty well every moving part including the main and rod bearings. A camshaft isn't expensive and lifters are cheap too but hauling out the engine for a total rebuild is. Why not just replace the cam and a new set of lifters for a couple of hundred bucks in parts?

Why not run it like solids if you want? Or just do like you did before adjust them with it running, it worked then it’ll probably work now, at least for a while.
I can see how several things could potentially go wrong, but heck it’s yours and you been down this road before.

maybe some of the metal particles in the oil has lodged in some of the lifters and has jammed/plugged some of the lifters .... no matter right? all's well?
summit has several sbc HFT cam kits with lifters for as little as $113

OK, this is a joke thread right?
Lifters are "frozen". Why worry? Run it? WTH?
A 61 has been under cover for 25 years and not been started. Well if it rev'd to 7000 then, go out and turn the key and rev it now. Then go for a pleasant drive. Don't wash it because the purists like dirt. Should sell for big $$$.
Yep, gotta be a joke thread.
