Title: Is it normal to be missing a pushrod when you take the valve cover off? LOL
Post by: Donjuan on April 05, 2009, 02:03:35 PM
So I purchased a new intake last week. When I went to put it on I pulled the valve covers off and found a broken Rocker Arm Stud, broken push rod, bent push rod and broken lifter. Needless to say i have been running all seven cylinders lately. LOL So now it is time to overhaul the engine. Hell it is only money right. If anyone has rocker arm stud girdles I am looking for a set. Till next time.  >:D

Well at least you know you'll be 1/8"th faster. Unless you're running a large roller cam I'm not sure if a stud girdle is necessary. Maybe when you get her apart you can tell what caused it. Wonder if it hydrolicked(how do you spell that btw,lol) or a lifter froze up, or?? If you smacked a valve could it do that?? Good luck on the rebuild.

Fix and go, why overhaul? So you snapped a stud, bfd...you can be on the water in an hour.

Same thing's happened to the Hondo.... twice.... but I could hear when it happened and I shut it off  ;D

BTW, anyone got some BBC studs and girdles laying around for sale?

so...this is what i found (something similar, but not to the same extreme)

(https://www.socaljetboats.com/index.php?action=dlattach;topic=6567.0;attach=24328;image)

There was a loud knock on the valve cover only upon firing up the motor...only did it 2-3 times then stopped.

previous owner said its the forge pistons getting "piston slap" because the piston needs to warm up and expand into the cylinder.  :screwy:...said he had heard it before and never did anything about it and the engine ran great (and strong!) with no issues.  :screwy:

to me it sounded like somethin goin on with the rocker...whatever....i used it as a vantage point to take a few hundred off the asking price.

there was no damage....pushrod was still straight....just reset the stud with some loctite and im on my way.

Interesting, a guy was telling me the other day my engine was overkill in the dependable department.  I went through a bunch of crap to put on this stud girdle, had to change exhaust manifolds to do it.
 ;D  He said you don't need a stud girdle unless you run 10 grand.
I'll show him your post.
