Need help. Doing heads, turned engine by hand & heads lift.

AIRBORNE STROKER · #1 (**permalink**) 11-24-2012, 04:29 AM

Doing ARP's, OEM headgaskets, etc... I reassembled rocker box, installed pushrods, valve bridges, and rockers. I have not put in injectors or glow plugs yet so heads are not torqued down, but studs are in.

My question is that I turned the engine over by hand (to put dowel in 6 o'clock and make sure everything looked good) and the driver side head lifted off the block. Do I have to torque studs first? Manual says to turn crank then torque but I can't imagine that heads are supposed to lift like that. Is there anything else I have to do now that I turned engine over? Any help would be greatly appreciated. Thanks.

This post is kindof confusing, but head the head lifting doesn't sound right.

Sent from my phone that somebody didn't help me get.

Could just be the push rods pushing up on the rockers, and the head is lifting istead of the valve opening. But that's an awfully heavy head to do that.

Sorry about any confusion. Not sure how to word it differently. I guess it just makes sense to me because it's all staring me in the face. I'm gonna take the rocker arms off and see if it stops lifting

Was just on Truckz actually on speed channel, full APR studs, oil cooler/pump, etc. Sorry I have 0 info for you though.

If you did it like this video it should be correct. Same procedure for ARPs except torque.
Notice he hand tightened the studs before going to the 6 o'clock, about 4:30 - 5:00 in the video. Maybe that is why yours lifted.

yes the pushrods will lift the heads long before the valve springs open. valve springs are very stiff plus there's 2 per rocker
