ticking lifter

guys-

got a lifter ticking when at idle and warmed up. I am a Ford guys, so ticking lifter means lifter not pumping up or dirty. However, on this 454, could mean I need ot readjust??? ALos, any suggestions on an additive, hopeully it could be from sitting up a while and a little dirt in lifter??
 
on the non mechanic side try discount auto i think lucas makes an oil treatment. I had a lifter ticking in my old ranger and that stopped it instantly and worked for about 6 months.
 
If you do have to adjust it, make sure your cam lobe is not round. You may have worn lobe, but hopefully the lock nut just came loose or a bad lifter. Good Luck. :wink:
 
I would make sure you did not tear up a cam lobe. 454 are real bad about eating cam lobes. If you run a flat tappet cam and you have not been using a zinc additive you probably flattened a lobe. Because of all the new polution laws they have removed zinc from 99% of all motor oil on the market. I use to run Delo diesel oil because it was one of the last companies to still have zinc, but they have now changed over also. Richard told me the Valvoline VR1 is still OK to run.
 
Need to know if it's an old style Mk IV 454 or a newer Gen V or VI. The newer gens have non-adjustable rockers and the older ones are adjustable. Granted, the old style 454s were known for eating cam lobes in the front (usually #2), and the fix is/was to put a .040 drill hole in the front oil galley plugs. But the newer engines aren't known for the problem, especially since the Gen VI is hydraulic roller. I'll be happy to help if I can get some more 411

the casting number is 10237297, thanks,

my research shows this as a 96 or newer gen VI, so hydraulic??

I got some water in the oil, clear rain though, due ot all the downpours here in san antonio. THe boat sat at my ex father in laws uncovered, with a crack in the air cleaner housing. I could just have some water in a lifter too>???
 
The cheapest, easiest test AFTER you change the oil is simply put a pint of ATF in it. The tranny fluid is very high in detergents and may possibly displace any crud or rust that has the lifter not doing it's job. If you have flattened a cam, it'll get worse quickly. The aft fix works over time, not immediate, but in a few hours usually. If it gets worse, don't run it. Can chips fall directly onto piston skirts and almost immediately kill rings.
 
I would check how much lifter preload you have if it's zero or less you probably have a lifter axle or lobe problem. Since it's the new mark VI check the rocker if it's loose and has lash and wiggles you found your problem!
 
Yes, being that it's a Gen VI it's definitely hydraulic roller. It's most likely that Potter has the best advice for you. The water has thinned out the oil and/or posibly stuck a check valve in one of the lifters. It's very doubtfull the lifter preload has changed since it's a non-adjustable valvetrain and those engines just aren't known for that problem, and there's basically no way you've wiped out a cam lobe, othersie there would be nothing but carnage right about now. Do an oil change as suggested with the ATF, then if the lifter quiets down, do another oil change to get the ATF outta there and you should be good to go. If that doesn't fix it THEN I would look closer at the valvetrain and find the problem. If that's the case I'd buy some ARP conversion/adjustable rocker studs and go from there.

What I meant is if the preload has changed it's because the lifter or cam lobe has been worn! I personally would pull off the cover first because if there is a problem the more you run it the more damage will be done and the more it will cost you. Check your valve lash it will only take 30 minutes and if it's good then be happy you got off the cheapest and easiest way, then all you gotta do is as Potter stated and run the ATF. Which probably is the problem like Felber said, these roller cam's and lifters hardly ever go bad but when they do the sooner you find out the less money it will cost you! Personally for me things never go the cheap or easy way and I never seam too get lucky and have a simple problem like that! Good luck!
 
Well Dave's advice is very good. Always better to err to the side of caution. I'm basing advice off of you saying it's "ticking". but my interpretation of that may be a lot different than yours. Because in my experience a roller lifter gone bad is a helluva lot louder than a tick and tends to more of a growling cry from inside your engine. LOL But like I said my "ear" is different so better to safe than sorry.

I changed the oil, and added ATF.......lifter is quiet even after engine is warmed up. I have a 2 hr trip to water, so will not have a chance to try it after working engine. Should I just run it a while on the trailer and then change oil, or run it on next trip(teal Season)?
 
forgot to mention, lifter was always quiet until after running under a load for a while. Also, running rotella 15-40, and the drained oild sure looks thinned down, event though it only has 3 hours on it, that is after oild change afer water was in it....

I ran Rotello once and I dumped it. That oil will break down under heat, unlike Delo. When I ran rotello my oil pressure would drop a little when the engine was hot , and I never had that problem with Delo.
