So after my head job I noticed oil leaking out around my valve cover, so I thumbed through my Chiltons guide and saw that the valve cover bolts are supposed to be torqued in that 53-63 ftlbs range, so figuring that was the problem I busted out my trusty torque wrench, dialed up 720 in pounds of force and got a ratcheting... and ripped one of the goddamn things in half. Now for the life of me I cant figure out what you call it, the parts monkey cant either. Im afraid to torque the others down now and rip any others. Same goddamn thing happened with the exhaust manifold and thermostat housing but I cant find what these things are... Its the 4 bolts on top of the valve cover... where do I get a new one and what is it called?
what the héll man! I HAVE NEVER HEARD OF SUCH TORQUE SPECS! just get those down till they are pretty tight... 34lbs MAX! or untill the grommets start to get smushed, then about 1 full turn or so. needs to feel firm and tight you must have mis read.....
i'm sorry to scorch but please don't torque them to 53lbs! thats scary! you could try the local jy or talk to one of the guys working at toyota dealership. or find a bolt long enough to reach down there of the same thread and pitch.
WoW!! Valve cover holddown stud maybe, and the nut torque is 8-11 ft# The head bolts are only 53-63 ft#
Valve cover gasket kit should come with the 4 circle grommets, 2 half circle end plugs and the big seal. Some also have the bolts. You need the valve cover acorn nut or the post? Easy on the elbow grease there hulk
The stud or the nut is what I meant. A good hardware or parts store should have the proper parts to fix it.
Headbolts might not be sitting Tighten those bolts down till you see the rubber compress about half way and thats good enough.I had the same problem and went thru many bushings.The problem was debri built up in the bottom of the head bolts threading(block side) that prevented the bolts from bottoming out completely.Just flipped the block on the engine stand and jabbed them with a wire then blew them out with the compressor and it was cherry.You can tell if this is the problem cuz the valve cover doesn't sit flush and has marks from the headbolts on the inside of valvecover.Good luck
yeah Im retarded double checked the manual and I was looking at head bolts, I remember thinking "geese these look kinda thin... but if the book says so..." so remember kids: Measure twice, torque once! Ill call around for replacing that stud, thanks everybody!
You could replace the whole valve train if the post is bad. I have a few of the cast iron rocker style. No spare aluminums.
