5.0L engines oil the rockers through the pushrods and lifters check those. check pushrod first to see if it is stoped up.

Flywheel torque spec's for 1983 Ford F-100


Could it be a F-150 instead?

These specs are for stock-type bolts with light engine oil applied to the threads and the underside of the bolt head. Moly and other lubes offer reduced friction and increased bolt tension, which will affect the torque figure. If you use after-market performance bolts like ARP's, you should follow the recommended torque specifications.

Ok so ik I'm posting allot haha but does anyone know where or how to adjust lifters just found out mine r just now needed adjustment in near mount Vernon WA or a price at least haha


In engines with rocker arm valve systems, the procedure I'm familiar with is to remove a rocker arm cover, and (one at a time!) while the engine is running, slowly back off the rocker arm retainer nut or bolt just until you hear the lifter tapping, then tighten it a quarter turn. If you can identify a lifter that is already tapping, tighten its rocker arm slowly until it stops tapping, then adjust it. Do not over-tighten! This can damage the engine.

Listen carefully to how the engine sounds; if it starts to stumble when you tighten a loose rocker arm, you've gone too far. If you cannot get the engine to run well without tapping, you may have too much wear in the valve train and may be due for a head overhaul, or you don't have adequate oil pressure in the lifters in question.
Repeat until all rocker arms are done. Replace the rocker arm cover using a new gasket, then (in a V-engine), repeat the procedure on the other side of the engine.

Wearing safety goggles, or better yet, a transparent face shield, is strongly recommended. Sometimes oil will squirt out a considerable distance from the lifter side of the rocker arm during adjustment, and the direction is not readily predictable.

Motor knock sounds like rocker arms or lifters?


If your engine is knocking the sound with be at the bottom of your oil pan but if you have lifter or rocker arm problems the sound will be at the top of your engine. One other thing you said your car has 315k it might be time to change your oil pump.

No oil pressure


may be it is oil pump, or oil gauge, removed your valve cover, start the engine you can see oil coming out from rocker arm, if there is no oil try to replace oil filter, if not again oil pump is the cause. replace oil pump.

What is the recomended torque setting for rocker arm nuts on a 289 ford mustang 1966


If all parts on this motor are stock and it is not a high performance engine but a stock windsor unit, there is no actual torque standard for the rocker arm nuts since the lifters are hydraulic. The manual procedure recommends the following:
with the motor off, tighten all rocker nuts until there is no slack between the rocker arm and the tip of the valve stem. Make sure each rocker is on the heel of the cam, this proceedure can be done one cylinder at a time or you can follow the ford V-8 cylinder identification for valve clearence sequence. I like the one cylinder at a time, it's a little slower but I think it's more accurate. after all rockers are set to the above mentioned clearance, start the motor and let the oil pressure build up in the lifters. At this point you should have installed the oil deflector clips on the rockers, just above the oil squirt holes, otherwise, things get a little messy. when the oil pressure is up, tighten down on each rocker until the engine starts to miss. At this point back off enough to clear the engine idle up and move on to the next rocker. Hope this helps.

Sounds like the engine makes a ticking noise could it be lifters


It could be! or it could be the rocker arms, if they have come loose just try to re-torque the rockers and see if you tick goes away. if not try some of that noise quite fluid. and see if that helps.

1. Install the camshaft after lubricating the journal of the camshaft with engine oil. 2. Install the camshaft bearing caps.a0b9a5d.jpg
3. Install the ignition coil. 4. Install the rocker arm and rocker arm shaft. Refer to "Rocker Arms and Rocker Arm Shafts" section. 83e48db.jpg 5. Using special tools, Camshaft Oil Seal Installer (09221-21000), press fit the camshaft oil seal. Be sure to apply engine oil to the external surface of the oil seal. Insert the oil seal along the camshaft front end and install by driving the installer with a hammer until the oil seal is pulley seated. bda0592.jpg 6.

Engine


if it's coming from the engine then the oil pump might not be getting any oil to lube the bearings or anything that needs the oil. In that case it could have actually messed up the bearings. Or a rod could be knocking. And one more thing is that the rocker arms may need to be tightend down.
