how to adjust valves
Hello All,
I am hearing a chattering sound from the right side of my engine - it speeds up when I speed the engine up or it is under load. It does not seem to be a blown head gasket. I think that the valves need to be adjusted. I heard that it can be done by hand at home, but I have never done one before and have no idea how to even start. Does anyone have an idea as to how to do this? I have a 1971 F100, 360, 2 bbl stock carburetor, 4 speed manual with granny gear.
Oh, I do have the shop manual at home and have been reading it.
Any help that you guys could give me would be greatly appreciated.
Thanks,
Andrew

Andrew your 360 uses hydraulic lifters with no provision for adjustment. If it's making noise something is wrong. Before you start into the valve train I'd suggest you take a good look/listen to the exhaust manifold. Ford's FE series V8's are notorious for developing leaks where the exhaust manifolds bolt to the heads. A small leak can mimic a noisy lifter.

when you say right sidedo you mean passenger side (correct way) or right side looking into the engine compartment from the front which would make it driver's side.if thats the case ive seen a weak fuel pump return spring make a clatter like lifters.take a wooden dowl or pvc pipe and try to locate it.good luck my freind,hopfully its somthing simple like that.

Ford did not install exhaust manifold gaskets on FE engines except for 406/427 HiPo's.
The only thing Ford did install was heat shields.
Over time, the manifolds can become slightly warped, so exhaust manifold gaskets are a must when this occurs.

Well, you guys were both right. The loud sounds coming from the engine compartment ended up being a water pump with a worn out bearing. Of course the radiator had sprung a leak and in the course of replacing the two (plus hoses) the heater core started leaking too!
I replaced the water pump, radiator, hoses, heater core and it sounds sooo much better. Running great, however that chattering sound from the passenger side engine still was there...I put my hand there and could feel the exhaust coming out. It was the exhaust manifold gasket on that side.
You guys are awesome! You told me more online about what was wrong with the truck than did than Ford Dealer - who refused to even look at it unless I paid them 150$ for a diagnostic.
I changed all the other stuff myself, but I am a little worried about the exhaust manifold and breaking one of those 40 yr old rusty bolts.
Thanks again,
andrew

But they do sell different length push-rods tho.
I got .060" over in my '75 360FE. :)
I run 15w-50 Mobil-1 to keep mine quiet.

Yeah Alvin I know about the different length pushrods. I figured to check the basics first then go from there.

hydraulic lifters are brilliant things and have so much more to them inside of them going on than what meets the eye. if they get gummed up then what will happen is exactly what happened to my stepmoms buick century when she never changed the oil. tick tick tick. my dad and her took it to a shop and quoted them $2,200 and then when they said no they tried to buy it off them. a new set of lifters costs less than 100 bucks and takes only a saturday afternoon of your time to install. (if infact that is whats wrong and u arent just throwing parts at a problem) i offered to fix it for them but they say "no its a junker and were getting rid of it soon"

Why do you need to change the rods? You have to pull the motor completely apart to pull the rods. To change the lifters you just need to pull the rockers, pushrods and intake. This is an easy job like mentioned above, except for the intake is real heavy. If you know the basics you can change lifters but rods takes a little more expertice.

I think he meant "pushrods". ;)
I mentioned the pushrods only to add to what Redcat said, that's all,
not because I thought it was a good idea for Andrew (the OP) to do.
Like Redcat said FE's rockers aren't adjustable.
At this point there are other things to try.
Like with DD's parents Buick, running ATF (automatic transmission fluid)
or something even better, might have fixed it up? Sorta? ;)
What about breaking in new lifters and a used cam? :/
The other way around is a bad idea.
To change to a longer pushrod the valve cover and rocker shaft needs
to be removed and everyone cautions the need to remove the bolts a
couple turns at a time until the pressure is off the valve springs and
the other way around putting the rocker shaft back. Also... they are
oiled through a certain rocker shaft stand and it has a skinny bolt so
don't get them mixed up. :) You'll see where that bolt goes if you look
for it. (one each side)
I still don't think that's your answer yet, tho. :)
