My car has a ticking sound. It was loud. Not a knock. How can I tell if I have a bad lifter? I have comp cams short travel lifters engine only has 1k miles on it. On a few lifters if I push down the back of the lifter it goes down a little. Kinda spongy. Some people say it's normal some say it's not.... I took a video and will post it up soon... Any help will be greatly appreciated.
Here's the video

If the rockers are adjusted right you shouldn't be able to push them down with your hand.

From what it's seems there's like 6-8 one more than the others, but I figured if it was more than one wouldn't it sound like multiple ticking sounds not just one?

One you 16 knocking will most of the time just sound like one is loose. I would re-adjust them an recheck to see if the noise goes away.if not pull the lifters out an check the cam lobes an rollers for abnormal wear.

The lifters are not pumped up. Are they NEW or did you bleed them down. The engine has to run for a while to pump them up. What you can do is pull the dizzy and install a dummy shaft and spin it with a drill. Then look to see if the oil comes out of the rockers. This will also pump up the lifters. If the lifters wont pump up they are dirty and the check valve is leaking. Good luck

Engine was running for awhile. Everything was still hot. Also checked to see if oil was coming out and it was when I was turning the engine. I'm going to check everything and re adjust everything. I just don't know if the rockers are suppose to move like that..

If it is a roller cam there is no need to worry about a flat cam or worn lifters. You can just replace them. They are not pumping up. Has the noize been there since the rebuild. If yes you most likely have galley plugs missing. Normally a hydrulic cam does not need readjusting if pre-load is correct. Hydraulic cams do not run valve lash they are pre-loaded. If the pre-load changes you have serious issues And that play is not normal after the lifters pump up. But it is normal before they pump up. Sorry to say you just might have galley plugs missing. Good luck

No the noise started at around 900 miles. If was nice and quiet before that. And yes it's a roller cam. Did the first oil change there was no metal shavings and car ran great. Still ran good just annoying loud tick. Almost like a rocker was hitting the valve cover but it's not.

Change the lifters. BUT. The original ford galley plugs are no longer available. The aftermarket ones are garbage and sometimes fall out. That is why i tap them and use threaded plugs. Good luck

I got it just like hydrulic cams have valve lash. Hay i never said roller cams do not have issues. The lifter can fail and grind down the cam. As the matter of fact ford really never had a cam issue because they learned early on about offset lifters. So there flat tappet cams were also tried and true as they say. Chevy on the other hand has an issue with there flat tappet cams in the early days. Strange things can happen. But it is far and few that a ford roller cam fails. As the matter of fact i sell the old cams to a friend that grinds cams. So tell me how many Ford roller cams have you seen flat that were that way without other engine issues. Because with my experience with them tells a different story. Also the engine is only 1000 miles old if i am reading him right. As far as bad info in my worst day . Well i am not even going to waste my time with your Nonsense. Now keep on telling people Hydraulic cams have valve lash. Now if the owner wants to replace the cam and lifters be my guest. But if that cam is wiped out in 1000 miles something is seriously wrong. Ford roller cams are tried and true. Now that is of course is if he is running a ford cam. And even if the cam was wiped out why is the lifter collapsed and not pumping up. If you have the experience you bullshit about you would know that a flat cam still has lifters that do not make NOISE. I have change many a cam in my career with flat lobes and the engines ran as quiet as a mouse. Or didn't you know that?? a collapsed lifter has nothing to do with cam profile. And the owner posted he had no metal in the engine. That is what he posted!!
Ford engineering answer to a question at SEMA I was there.
Chevy had engines with cam lobes directly under lifters for a while and it caused a lot of cam failures. The cure was to move the lobes away from the center line of the lifter bores so the lifters could rotate on flat tappet cams. Ford did not have this issue and when Ford switched to roller cams they were bullet proof as they say. Roller blocks are not offset. And roller cams are never run offset.

Well I have adjusted the rockers to specs. Almost all of them where off according to what they are suppose to be. Couple where so off idk how the pushrod stayed on the rocker. Tomorrow I should have it fired up and hopefully the noise is gone..... If the noise continues I would assume it something more serious? What else could it be if the noise is still there?

If the noise is still there tear down will be need to do a visual inspection of the lifters an cam journals.

What sucks is that I need to take my heads off to take the lifters out... Tried taking one out and it hits the head.

If I would have known the aftermarket lifters would do this I would have never gotten them.

who makes the lifters you are using?? That lifter pictured above is classic of a roller failure. That in turn wipes out the cam. Like i said something has to go wrong to wipe out a roller cam. Looks like a seized roller or the roller is soft. Have a great evening guys
