what could cause the rocker arm to freeze??? i just had valve springs and titanium retainers put in through a machine shop and after it came back, me and my friend looked at it and the rocker arms were frozen...what would cause that??? did the machine shop screw me over or is there something wrong??? a shop told me that a warped head or a worn rocker arm would cause them to freeze...any ideas???

 

low oil bad valve adjustment. and thats about it.

 

but it all worked just fine before...now when you even try to take off the rocker arm is will not come off at all. the place that has the head now is looking at it, but they don't know what caused it. any other ideas??? thanks for the reply

 

They might have mixed up all the rocker arms,...or tried using one of the shafts as a breaker bar

 

probably did...they screwed something up. i find out tomorrow after this other shop looks at the head...i'll let you guys know. thanks for the replies

 

If the rocker shafts are installed incorectly the oil holes can be blocked causing a lack of lubrication. That usually wears out the rockers and shafts, but it could cause them to seize also.

 

here's what happened, my dumbass friend tightened the bolts that hold the cam caps way too much...actually threaded them past the threads. that casued the rocker arms to freeze because that shaft can't move...the head is trashed. getting all the parts to fix it for $100. thanks for the replies
