So I was just drivin down the road and my truck sputtered, started makin a clickin/tickin/tappin kinda noise and died. Noise was from the drivers side. I let it sit for a couple minutes and it started up still makin the noise and sputtering. What happened? Broke valve spring, collapsed lifter? Broke piston? It will still start but it don't sound pretty. There is oil pressure. No leaks underneath

 

Get video of the noise if you can, it might make it easier to diagnose.

Where you getting on it real hard when it happend?

 

Pull a valve cover off and look.

















My chances just got really good

 

i was just driving down the road. i haven't been hard on the truck in awhile. i'm confused

 

You really need to get a wideband.

Could a clip have came off a valve? Or you may have broke a spark plug some how?

 

you probably broke a valve spring.. or lifter... thats the most likely problem...... pull the valve covers and tell us what you see....

holy crap how are you putting down that much power.. that must be one hell of a cam....

 

man i just got your messages this mornin. sounds like you had a shitty night give me a call.. i know were an lq9 is for 1200

 

Man that sucks, I'm guessing valvespring or something in the valvetrain. Pull the valve covers and take a look...

 

If you're getting a bad squeeling you may even have a lifter that decided to rotate....... Then it's time to start shopping for a new motor

 

One of the new comp 918 springs broke.. valve is gone completely..pics coming later..
