If it leaks you're probably going to have to replace the gasket.

replace the gasket

the gaskets are cheap,and ask the auto parts place if they have a manual,they are worth the few dollars that they want.that way you do not have wrench monkeys torqing your wheel nuts to 250 ft lbs.. these gasket amounts vary from 25 to 50 ft lbs.

Way way lower than that. Around 80 inch-pounds.

...Torque valve cover gaskets to between 25 and 50 "ft lbs". A wrench monkey might also be someone who isn't smart enough to know that you torque to lb/ft or lb/in.

Yah, I've never heard of a valve cover needing to be torqued 25-50lbs. Nor have I ever seen someone break out a torque wrench for it. Just make it good and snug.

Good God almighty!!! I thought everyone knew all valve covers were the same.
The proper specs is 35ft.4in. lbs and is done with a torx wrench!!!

with alot of things tight enough to hold but not tight enough to strip the threads is fine, but with gaskets and mating flanges, if you can do it with a torque wrench then by god do it with a torque wrench, everyone says fel-pro cork is crap or (insert company name here) is crap , a gasket seal is only as good as the installer. even torque across a valve cover is crucial because you can warp it easily or flatten the gasket very easily. these gaskets will work properly if installed properly

wheel nuts not torque

the 250 ft lbs was not for the valve cover gasket,I was making reference to the guys at canadian tire that torqued my WHEEL nuts to 250 lbs.do to the overwhelming response in a smart way, I re- read my original answer,and I said 25-50 ft/lbs. that is too high.ESPECIALLY AN ALUMINUM ENGINE.the exact amount will be found with the manufacturer of your engine.AND I stick with the engineers at haynes on that one,with ft/lb.see page 2a1 isbn# 1 56392 212 6 manual.its for a 1987 3.0 l ford v6 the valve cover bolts are 6-8 ft/lbs ,NOT LB/FT.if you torque a bolt down,the torque remains ,maybe it is different for something that generates torque.hmmm.
The valve cover gaskets vary, some might be 8 ft lbs.SOME 12,and some big engines are more than that. I did not think it was so important to specify lb/ft or ft/lbs as to the reference of the fact that the haynes manual I am reading for the 1985 thru 1995 sable,says FT/LBS for ALL THE TORQUE SPECIFICATIONS. SO DOES THE MANUAL FOR MY OTHER CAR. I know pilots out there who are so expert that they skip using a checklist.THEY ARE EXPERT.Well I have been flying aircraft for 26 years and still use one.They are usually the ones that end up getting killed over a stupid mistake.If someone works on cars everyday,a torque wrench might seem to be a waste of time especially for flat rate work,but when a guy is trying to save a dollar,WHY BEND A VALVE COVER ?or go thru 4 gaskets?.furthermore..some designs do not use a gasket but a sealing compound.better quality gaskets are laminated.Do BMW torqe specs say"tight"? A LITTLE TOO MUCH ?OOPS
There are varying degrees of self proficiency out there,such as :"tight and then a quarter turn".thats why i just replaced a stripped oil pan on a 2000 vw 2.o because someone stripped the fine pitch oil pan bolt.IT IS AN ALUMINUM PAN.the bottom line is this:if you want to guess,thats o.k..it comes with CHANCES..BUT WHEN THE ENGINES ARE ASSEMBLED AT THE FACTORY,they use torque wrenches,robots,computerized torque jigs etc. The torque settings are there for a reason,especially for the home fix it guy.I TELL YOU SOMETHING, my father was a jet turbine overhaul engineer,and EVERY BOLT on that aircraft was done right.If cars were given the same care and nuts subject to vibration were wired and drilled,LIKE AIRCRAFT half of these problems would not exist anyway.You take any car on the road and if it has seen 3 years worth of warranty work,and you pull it apart,every goddamn bolt will be out of spec.,that was ever touched .just think,....all those broken bleeder screws. I WORK ON CARS FOR FUN,BUT I AM A PERFECTIONIST AND I DO NOT GIVE A @##$#@! IF IT TAKES A FEW MINUTES EXTRA.,BECAUSE IT IS DONE PERFECT.

forgot something

wonder what the valve cover specs are on a lycoming 500 series aircraft engine? think they only torque those bolts to 80 inches so they can fall off?.
its a 4 cylinder air cooled engine producing 200 horsepower.gaurantee you that this engine needs more than the 8 ft/lbs in the 3 litrev6 and thats why i said to guy originally,CHECK THE MANUAL......there ARE valve cover bolts that
high ,i am going to waste some time and post all of them when i find them...
in the 25 to 50 ft/lb range.

wow all this.

i really do not care for proper spellig punktuation etc.this is not a spelling or english test.HOWEVER ,IT IS FT/LB.torque is a rotational force.work can be a linear measurement.or non linear for that matter,such as torque produced by an accelerating engine.the energy that remains AFTER THE TORQUE IS APPLIED,IS ACTUALLY KINETIC ENERGY.AS FAR AS CHECKING THE BOLTS ON AN AIRCRAFT,good point ,all pre flight checks say check the engine oil,etc under the cowl.did you know that the only people allowed to service their own aircraft,other than an AME are owners,if they have built their own airplane.
speaking of if we ever helped that poor kid out,if he puts the manufacturer,and displacement of the engine,i or any of us can look it up,and he CAN USE A TORQUE WRENCH AND TORQUE IT IN THE SEQUENCE,USING THE EVER SO POPULAR FOOT/LBS. speaking of what is a foot lb? is it the energy required to move one pound 1 foot in one second,or 1 minute? does torque change at say 50000 feet? we can get into that too.hey if you torque something to 100 ft pounds,and then heat it up yo 350c
does the torque energy ,stored as kinetic (in a spring say) change?.
