Collapsed lifter...pushed rocker stud up and rocker was hitting valve cover. I guess the lesson here is to not reuse your used lifters on a new motor? Buying a new set tomorrow. So glad I dont have to pull the motor out. Need to pull radiator out in order to get to my crank bolt to set lash on all the lifter again. new intake gaskets, and then we should be back on the road.

New lifters are always a must for me. I hope that does the trick... Also check the oil. I had a rocker stud back out and leak coolant into the crank case, destroying my cam bearings. This right after the heads were rebuilt! Needless to say, I demanded screw in studs on the next set.

They are AFR heads so they are screw in studs...thats kind of the crazy part..those were screwed in with thread locker and they still backed out...weird

Why pull the radiator? If you pull the coil wire, you can use a screwdriver to jump the B+ and S terminals on the starter solenoid (or use a remote starter to jump them) to turn the motor over until that cylinder is on the compression stroke. This will place both lifters on the base of the cam lobe for proper adjustment.

thats right. thanks starfury. I normally adjust the intake when the exhaust starts to open and then adjust the exhaust when the intake starts to close. half turn past zero lash

Dude, I know that can be a soul crushing experience so you have my condolences as far as that goes, but damn; Why in the world did you reuse old lifters on a new motor? You're in to it for hundreds of dollars at least already so why scrimp now?

Hopefully you got away with one and chalk it up to a lesson learned.

Glad it wasn't the bottom end. Sounds like you'll make out.

Was that a roller lifter?

I dont put much faith in AFR after a buddy broke a rocker arm stud on a AFR head in less then 2K miles.

eZ

yes it was a roller lifter. searching around town for lifters now.

fastbackford351 - yea lesson learned for sure. but hey thats what its all about.

Don't you have to remove the heads to pull the roller lifters?
