I realize that i'm new here and that i haven't formed any "forum friendships" yet but i just needed a place to vent...
So about 2 weeks ago i took a very long drive to see a car in another state. I was super excited and at the same time tired of seeing the rotted out SH1T for foxbody's local to me. This one looked great in the pics, sounded pretty damn good too. The previous owner was responsive and answered all of my questions.. I had my finances in order and took the ride..
The good:
-3yr old paint - done "mostly right" -- as in - door panels removed, windshield removed, Headlights/taillights removed.. (Saw a video of it getting painted).. it was an acceptable job.
-NO RUST.. I went top to bottom - looked over all the known bad places - everything is GOOD. Strut Towers are solid as a rock, Rear hatch is perfect, underside of doors have nothing, Floors are clean, pinch welds are mostly straight and not rusted..
-Interior is clean (new headliner and carpet) Retrofitted 2017 Mustang seats in the front too so it adds some modern touches and i actually like it.
The bad:
-I suspect that theres a fuel issue - although its unconfirmed. Car seems like it runs obnoxiously rich.. if i have it idling in my garage, i smell like gas.
-"The clutch just went - i've literally had the car for less than 100 miles.. (i test drove it, it was grabbing high in the pedal but i didn't think it was that bad)..I guess it was.."
-The motor - its a 351w, with all the 5.0 EFI stuff. It has aluminum head and its makes a crap ton of noise.. I think its the valves/rockers.. preying its not a Rod or multiple Rods... When i first heard it, i thought it was just injector cycling.. But - maybe not..
-The Tach is messed up - it revs up to 3k only.. even when i know im well beyond that..
-The stock temp gauge doesnt work - but an aftermarket one installed by the previous owner does.. I hate it.. i just want the stock gauges..UGH..
-The Speedo bounces at lower speeds 30mph and slower..
-Electrical - I suspect there to be other electrical issues based on some odd behavior by the radio.
There are other odds and ends that to be honest, i was looking forward to "working on".. but with each new discovery i feel more and more defeated.. I know (after reading some of the posts here ) that the guys on this forum would probably laugh at my list of issue and just blow through fixing them but i'm likely less skilled and certainly less knowledgeable so the task seem daunting.. AND Expensive..
sorry for the rant..
"

As previously mentioned look under the car to see if the exhaust system has catalytic converters on it. No converters, that's the possible source of the stink. The other possibility is that the fuel tank vent system has been mangled and is venting to open air. The check for this is to dumpy the computer codes. Look at the top of the 5.0 Tech forum where the sticky threads are posted. One of them is how to dump the computer codes. Codes may be present even if the CEL (Check Engine Light) isn’t on. You don’t need a code reader or scanner – all you need is a paper clip, or if your lady friend has a hair pin, that will do the job.
I highly suggest that you read it and follow the instructions to dump the codes.

"The clutch just went - i've literally had the car for less than 100 miles.. (i test drove it, it was grabbing high in the pedal but i didn't think it was that bad)..I guess it was..." There should be ZERO slack in the clutch cable. The clutch is designed to run with 5-10 lbs. of tension on the cable.
Clutch Adjustment for stock and aftermarket setups
Revised 28-Apr-2016 to include need for longer cable with single hook quadrant
Clutch adjustment with stock cable and quadrant
There is a self-adjusting mechanism for the clutch cable. As the clutch wears the cable tension changes, that is why there is a self-adjusting mechanism built into the clutch pedal. There is a toothed plastic quadrant with a ratchet pawl that engages the quadrant. As you pull up on the clutch pedal, it ratchets and takes any slack out of the clutch cable. Mess around with the pedal or even bump it while the end that fits in the clutch fork is loose, and it tries to take up the slack in the cable. That has the effect of shortening the cable.
Do the clutch adjustment first before considering any other problems. With the stock plastic quadrant and cable, pull up on the clutch pedal until it comes upward toward you. It will make a ratcheting sound as the self-adjuster works. To release to tension of the stock quadrant, use a screwdriver to lift the ratchet paw up and out of engagement with the quadrant teeth.
You can use a screwdriver to lift the ratchet pawl off the quadrant teeth. That will allow you to move the quadrant to allow more slack in the cable. If the cable is too loose, pull up on the pedal. The ratchet pawl will allow the quadrant to take up the slack in the cable and lock the adjustment.
Adjustable cables are used when the plastic quadrant is replaced with an aftermarket metal quadrant. The downside to this setup is that you have to get under the car to adjust the clutch. Add a firewall adjuster to an adjustable cable setup and you can spare yourself from getting back under the car to make any fine adjustment that you desire.
The fancy 2 and 3 hook quadrants are for use with stock length cable and a firewall adjuster. Use the firewall adjuster and screw in and out to take the slack out of the cable and get the clutch engagement point just where you want it.
Binding clutch cable
A binding clutch cable will make the clutch very stiff. If the cable is misrouted or has gotten too close to the exhaust, it will definitely bind. The binding common to adjustable cables is often due to misplacement of the adjusting nuts on the fork end of the cable. This will also cause the cable to wear and fray. Both nuts should be on the back side of the fork so that the domed nut faces the fork and the other nut serves as jam or locknut to the domed nut.
Clutch pedal adjustment
Clutch pedal adjustment with aftermarket quadrant and cable: I like to have the clutch completely disengaged and still have about 1.5” travel left before the pedal hits the floor. This means that I have only about 1” of free play at the top before the pedal starts to disengage the clutch. Keep in mind that these figures are all approximate. When properly adjusted, there will not be any slack in the clutch cable. You will have 4-15 lbs. preload on the clutch cable. With a non-adjustable cable and a firewall adjuster, the cable needs to go in the second hook of the quadrant. Single hook quadrants used with a firewall adjuster may make the clutch too tight, causing it to slip. The possible exception to this is the Maximum Motorsports cable which is a bit longer to make it work with a single hook quadrant.
Adjustable clutch cable tips:
Loosening the cable adjustment nut (throwout bearing arm moves to the rear of the car) moves the disengagement point towards the floor.
Tightening the cable adjustment nut (throwout bearing arm moves to the front of the car) moves the disengagement point towards the top of the pedal.
Firewall adjuster tips
Turning the firewall adjuster IN makes the engagement point closer to the floor since it loosens the cable. You have to push the pedal to the floor to disengage the clutch. Too loose a cable and the clutch won't completely disengage and shifting will be difficult. Gears will grind and you may have difficulty getting the transmission in first gear when stopped.
Turning the firewall adjuster OUT makes the engagement point farther from the floor since it tightens the cable. You push a short distance to disengage the clutch. Too tight a cable will cause clutch slippage.
Aftermarket solutions to the problem:
The quadrant needs to be replaced if you use any type of aftermarket cable or adjuster. My preference is a Ford Racing quadrant, adjustable cable and Steeda firewall adjuster. The adjustable Ford Racing cable is just as good as the stock OEM cable. It allows a greater range of adjustment than a stock cable with a aftermarket quadrant and firewall adjuster. Combined with the Steeda adjuster, it lets you set the initial cable preload and then fine tune the clutch engagement point to your liking without getting under the car.
Using a stock OEM cable, firewall adjuster and a single hook quadrant may result in not having any free pedal travel before the clutch starts to disengage. I found this out the hard way.

Grabbin' Asphalt
Help for those who have replaced the clutch assembly and are still having problems with adjustment:
The next step doesn't make much sense it you already have the transmission installed, but just for sake of discussion, here it is:
The throwout bearing sits in the clutch fork arm with the wave springs pressing on the rear flange of the throwout bearing.
Major differences between the distance between the flywheel surface and the clutch fingers may require tinkering with the clutch fork pivot ball. Stack your old pressure plate, clutch disc and flywheel up like they were when installed in the car. Tighten down all the pressure plate bolts and measure the distance between the clutch fingertips and the flywheel face.
Too much thickness will cause the clutch fork arm to sit too far back to get the clutch cable on the quadrant. It may even sit against the rear or the bell housing hole for the clutch fork arm. In that case, reduce the pivot ball height.
Too little thickness will cause the clutch fork arm to sit too far forward and bottom out against the front side of the bell housing hole for the clutch fork arm.. This will prevent the clutch from fully disengaging.
In other words, the clutch fork arm should sit positioned midway or a little towards the rear in the bell housing hole for the clutch fork arm when the cable is properly tensioned.
"The motor - its a 351w, with all the 5.0 EFI stuff. It has aluminum head and its makes a crap ton of noise.. I think its the valves/rockers.. preying its not a Rod or multiple Rods... When i first heard it, i thought it was just injector cycling.. But - maybe not." Loose rockers and especially roller tip rockers are noisy. There are two types of rocker arms on 5.0 aftermarket heads. Pedestal mount which is the stock style and stud mount like the old small block Chevy's had. The following procedure is only for the pedestal mount rockers.
Michael Yount’s valve adjustment procedure
Here's an easy way to determine this. Start with the #1 cylinder. Rotate the engine with a ratchet on the crank bolt clockwise. Watch the #1 pushrods. First the exhaust pushrod will rise and fall signaling what would be the exhaust valve opening and closing if the rocker were on. As it closes the intake pushrod will rise -- keep rotating clockwise until the intake pushrod falls and is level with the exhaust pushrod - both at the same height. Both lifters are now on the base circle of the cam - both valves would be closed if the rockers were on.
Now, install both rockers. Tighten the bolts with one hand while rocking the rocker with the other hand - continue until you reach the point where you can't 'rock' the rocker any more because there's no gap on the valve stem end or the pushrod end. You are at zero lash - i.e. - no gaps. Stop tightening just as you reach this point.
Now, put your torque wrench on the bolt and tighten it to 18-20 ft-lbs while counting the number of turns it takes to reach the torque. You should hit the torque within 1/4 to 1 turn of the bolt. If it takes more than 1 turn, use a shim to raise the rocker -- each .030" shim will reduce the number of turns to torque by about 1/4 turn. If you reach the torque in less than a 1/4 turn, or you have trouble reaching zero lash even at full torque, then you'll either need longer pushrods, or to CAREFULLY remove some material from the bottom of the rocker fulcrum. Using the procedure described above, you will work through the remaining 7 pairs of rockers. If you follow the firing order, it will minimize the manual cranking you have to do to get the lifters on the base circle of the cam prior to installation of the next pair.
When I first went through mine, 13 of them took no shims; 3 of them took 1 .030" shim. Upon cranking it up, one or two of them sounded a bit noisier than I thought was right, so with the engine hot, I pulled the upper off, and the valve covers, and went through the installation procedure again. That time, 11 of them took no shims; 4 of them took one .030", and one of them took one .060" shim. And they were very quiet running.
I'm going to stop here and start a new post so that this doesn't run out of space...
