6.5 predator. Pushrods keep falling out

[Chevyman1987]

I got a 6.5 predator motor. The push rods keep falling out. The motor will crank and run then shut down. Pull the value cover and there just laying there. So what could be causing this? Also what is the value lash .005?

Flat cam lobe , bent push rod , bent rocker arm , bad harmonics , could be a number of things. Why did it do it in the first place before this problem started ?

I just bought a gokart today and it was on it. Don't know anything about it other than when I set the value lash at 005 it will crank and run and it I try to give it some gas the pushrods will fall out. But the pushrods are straight and so is the rocker arm. I was thinking maybe the cam lobe. But just wanted some input on the matter before I started tearing into if it might been something stupid simple lol

Unless I'm mistaken, valve lash is .003"

Are there lifters under the pushrods?
How about a picture of the installed valve springs and rockers and p-rods?

Yea I took the side cover off and everything checked out ok. Put it all back together lined up the cam and bam it's been running all day. Don't know what the problem was but it's running with no problems

Ah, the old "take it apart and put it back together exactly the same" trick. Works often.

lol I know took it apart everything seem fine nothing loose and nothing seem worn out. I guess it wanted to air everything out lol
