Ok so i was putting together an LS tonight, totally stock motor.... I Was taking out the headbolts one by one and replacing with ARP's. That went over smooth and then I took off the cam gears. Well I was drinking and talking with friends and one of the cam gear keys/keepers fell into the bottom of the timing cover! So I was trying to get the crank pully off and long story short the bottom end turned and the cams didn't. So basically I'm wondering if the bottom end turned almost a full revolution with the cams at TDC, do you guys think it would bend the valves? I'm hoping not, only because the low compression of the LS motor, I thought There may be enough clearance for it to happen? I just want opionions.... TIA!

id be willing to bet you'll be ok.

id risk it, slap it all together and see what happens.

put the motor to TDC, put the cams straght up

put thebelt on

easier than fuckign your motor up

Thats what I was hoping, I've never bent valve's in a build, but I thought it would be pretty obvious if I did The head never actually came off the motor for the ARP install. The motor only made about a 3/4 turn, but more or less I'd rather not take it back apart if I dont have to. But if people think their bent for sure then I guess I'll pull it apart....

The build should be lots of fun, I picked up a 93 LS tranny with a quaife LSD for $650 today, 0 miles since rebuild, I think thats a steal since the LSD is a grand alone lol

do a leakdown test and that should tell you for sure, but other than that, I think you're just drunk and worried for no reason. lol

LOL Ya I am drunk now, I've never done a leakdown, can you buy a leakdown tester for a reasonable price? I've never really looked into it at all, Ive just got a few compression testers

dude if you were turining the motor over by hand, you would feel if a valve hit a piston. I t would be basically a dead stop. you should be cool

Thanks, I just felt like I hade to of fucked my motor up, but now I feel better lol

Although My problem was I was trying to get the crank pulley off with a huge torque wrench so I dont think I would have felt it, but I guess ill find out

you would feel the resistance of metal on metal before the valve bent. lets just hope you werent too drunk to notice
