hey folks! just been putting some serious summer miles on the ol' girl, just rolled 1300 miles on the hemi, and things are still dry underneath, thank the car gods! one kind of unsettling thing has popped up, a loud lifter noise. started out as 'tick tick tick', then got really audible. i got spooked, so i removed a valve cover, (THAT was fun.....n't.) she was rtv'd reeeeeal good on there. anyway, exhaust valve on cylinder number two was about .005 out, all the others on the comp hydraulic roller rockers were at zero lash, as recommended per comp cams. the adjuster was tight, so not really sure why one rocker got loosey goosey on me. i adjusted it, and it sounded fine, but i have a slight 'tick tick tick' again, which scares me a little more. it has stayed steady right where it's at, so i am just going to ride it out, and see what happens. anyone else have an issue like this? i tried to contact my engine builder with a few questions on troubleshooting/remedies, as it's his engine, he would know, and i thought it a fair question for such an expensive investment. but, eddie haines stuck to his M.O. of not responding to me at all, with any help or suggestions. HORRIBLE customer service, end rant. stay tuned for the next adventure!

well, my antique auto battery brand mopar replica, (the glass mat version), took a dump on me. it had a loose negative post, and would not hold a charge anymore. it would charge, and show fine, but it would not recover once a load was put on it. crank on it more than a few times, and it would be dead. tried several methods of trying to help it get it's 'memory' back, but to no avail. contacted antique, and they were STELLAR to work with. i was out of the one year warranty, but they said pay for shipping one way, and they would take care of it. got a brand spankin' new battery, and it works great! while it was out, i put in a new battery hold down setup, mine was too short, and was looking it's 40 plus year age, even after refurbing it a bit.........

hemi down. as soon as i got her going, another hiccup. started running like crap on the way home from a drive, missing on at least one it felt like, but intermittently. by the time i got home, a steady miss on cylinder one.... checked plugs, ignition, wires, and oh, had lifter noise again. it didn't seem like a slightly out of adjustment lifter could cause this, but i had no other ideas, so off comes the valve cover..... everything seemed right, zero lash on all holes at tdc. then, i pushed on the exhaust rocker on number one, and it compressed over a 1/4"! it felt like the lifter didn't/wouldn't pump up, and hold oil.... i managed to get the pair of roller rockers out of the head hole with a magnet probe. (wonder if i can get the new pair back in! sure would be nice to not have to tear the top of the engine off). i found a teeny tiny piece of rtv stuck in the oil feed hole. since i have chased this rear main leak so many times, and the engine has been out and apart several times, i must have missed a piece, and somehow it made it past the filter..... anyway, it appears it got plugged, ran dry, and beat it self up, breaking the valving plate in the lifter, rendering is useless, and not really opening the exhaust valve...... well, at least i figured it out, and hopefully i can get it sorted out quickly......

they are comp 8921's, (i broke the ladder bar off so i could investigate, can't get the plunger out when they are together). it doesn't appear to be any fault of their own, i am hypothesizing that the little piece of chewed up rtv i found in the feed hole starved it out, and that somehow caused the little valving plate to break due to lack of oil, or pump up...
the fun part, will be trying to fish the new set in through the head without taking the intake off, like i got them out!
but hey, i have no rear main leak now! lol.............

If you can get the lifters into the valley through the head, then you can use a magnetic pickup and a 1/4" piece of wood doweling. Use the wood stick like chop sticks to move the lifter into position, then hold it in the bore and pull of the magnetic pickup tool. I have pulled many flat tappets out for inspection and replaced them. I'm not sure what type of chellenges the rollers may add though.
Good luck.

Pull the distributor out and feed the lifters through the hole.

whew! got 'er done, but not how i envisioned it, just had to roll with it, and do whatever worked. ended up being a mishmash, long needle nose, stainless wire, long screw driver, and multiple lights. finally got them in and seated, all put back together, primed, and fired for a few seconds to verify all was well. all doned up, just waiting for the rtv to dry, and maybe take her for a test drive tomorrow!

man your brave if I lost a lifter I would tear the motor down searching and cleaning the whole thing out. Were all the pieces there when you took them out to out the lifter back together?

in short, the only thing i 'lost' was the diaphragm inside the hydraulic roller lifter, it just wouldn't stay pumped up. all the bits from the diaphragm, 4 or 5 pieces, (see pic) were contained inside the lifter still when i took it apart. everything looked perfect, the roller, lifter bore, pushrod cup, pushrod, no marred surfaces, and nothing could get out of the lifter, due to the pushrod covering the hole on top, which also looks perfect....
i too would have torn it down to parade rest if it were an actual metal wear problem on any surface, but it really doesn't appear to be anything like that......
