Valve train people .... come inside.
OK I have read post after post on this ticking thing . I to have this problem with a tr224 cam and 7.425 pushrods.
Everything i read is people say pushrods are not long enough. But when they go to fix the end up going shorter pushrods and makes it better. Then everyone is like no no that is not possible. So ******* lost here!
Would a pushrod bottoming out the lifter cause this sound?
A tr224 cam has a .030 smaller base cirlcle . so by alrights the 7.425 should be money and with no tick .
The tick I have is hardly heard at start up .Only when i get some heat in the motor. So lead me to believe that heat is causing expansion and making the sound?
The sound is constant doesnt get louder or softer just more constant as the motor revs.
I have great oil pressure and car runs good , but I'll be damn if i am gonna just let the **** go like most people do. It wasnt the way before the cam so I dont want it that way after the cam .
I put 918 springs long tube headers on aswell. I understand the yes it should be louder.
Is anyone in here running this cam and pushrod combo or what is the pushrood length you are tunning with your tr224 cam .

If I were you, I would do one of the following:
-Get a pushrod length checker and make sure you have the correct length.
-Get new lifters. It sounds like the lifters just might not like the extra strain of an aftermarket cam, even if its a baby 224.
-Change to German Castrol 0W-30 oil. It has been known to get rid of lifter tick.
-Pour about 4 oz. of ATF in the oil. This has also been known to get rid of lifter tick.

* Who ever said shorter PR's reduced ticking?
* It's primarily the profile of the lobes that dictate the ticking volume.
* Headers make it louder.
* Installing roller-tipped rockers will slightly reduce the ticking.
* If you can't stand the ticking, pull the cam and go back to stock. You wouldn't be the first to do so.

Nice
OK first of all i didnt take the oil pump off or mess with it!
My main question was would the lifter bottoming out cause it to make that sound aswell .
I really dont want to take anything out. I love the cam and everyone I talk to on here says there tr224 is quite as a mouse with 7.425 pushrods. Did i do something wrong in the install . The car does run great and dynoed at 381 hp 367 ft of tq. I pulls really hard and what not . Does anyone on this site have a sound of lifters vs. injector sounds ?

^ Get the Pushrod length checker to be sure you have the correct size PR's.
If you are w/in .025 of Push Rod Length, you shouldn't have a problem bottoming out. You should expect some ticking after a cam, even thought the 224 is a reletivley mild cam.

If the lifter was bottomed, your valves would likely not fully close and you would notice a power loss. If it is running strong with no indication of a problem, then lifter bottoming is not an issue. Always best to check the length, but I ran my Crane cam with Crane adjustable rockers with a lifter preload of 0.125" so even if your exact length to get 0.100" preload was the stock length, you would be where I was with preload with your longer pushrods. I think you are fishing in the wrong pond with the lifters bottoming. Get an adjustable pushrod and verify your length. If your length is OK, you could try roller rockers to see if they quiet it down some. Ramp rates will play a major role though.

7.400" TR PR's here with my TR224. I've ran these with my Patriot heads and also the stock heads. No ticking. Valvetrain is louder than stock but there is no audible tick like you have described.

How about guys with cams here throw some vids and sound clips up !

Stock Rockers? If so, then the pushrods are longer than stock, but if you're runnin 1.7 rockers and a 224, then i see no problem with a 7.425 pushrod, you gotta get used to the lifters. what's your lobe separation?

-=Modified=- and i had the same damn ticking issue.. We racked our brains on it for a month...
We replaced the lifters and the oil pump pickup O ring.. One of those solved it. sound coming from the driver's side?
Jason's car was stupid loud.. I'll upload a vid. You could hear it better from under the car..

We did the lifters and the O ring at the same time, so I'm not sure what exactly solved the ticking. The O ring steadied the oil pressure, tho.
It has some noise now, but normal noise for a big cam. I'd say you have a lifter issue. If you did the pushrod length check and found what you needed... Did you get a swipe pattern?
