GGaaaaaa Camshafts!

Damn!
Ok, the water pump went out on my 94 850 Turbo wagon. How hard could it be? When I got the water pump out, the gear had SNAPPED in two! I do not know how the car ran like that! I marked everything, reading here and everywhere. When I put it back together, there was too much slop in the intake to crank path, and its been downhill since then. THERE ARE NO V MARKS ON THE PLASTIC. THERE IS NO MARK AT ALL ON THE EXHAUST CAM!

THERE ARE NO WRITEUPS ON HOW TO SET THIS!!!

The best write-up, with pictures, I've seen in on the FORD EXPLORER'S site!! That's just sad. OK I'm done venting and here's my question: how do you know if the cams are 180 degrees out or not? Because they are going to line up twice horizontally. That's where I'm at. I have to get this car back on the road. I know I have a very good chance of bent valves, but let's stick with one problem at a time, shall we?

EDIT:
Just found this awesome tutorial, I swear I searched everywhere for this! This is starting at the timing belt reassembly portion...

If you take off the cam positioner sensor, (it is on the drivers side of the car on the end of the cylinder head) the slot in the cam should be paralell with the cylinder head. There is actually a tool the holds the exhaust and the intake cam in position when doing a timing belt change.. I've done it before without the tool though by marking positions with typewriter white out. There is a plug in the engine block that you can take out and put a 6" x 3/8"socket extention to get the engine at TDC. You need to take the starter out to do it though. There are write ups on it.

Thanks, but my point is that those slots, once the cams have been moved can be 180 degrees out! In my case I'm fairly certain that my intake or exhaust is flipped over (after looking at the tutorial I just discovered.) Why can't you find those BEFORE you start the job?!! ( the tutorial I mean...)

What if you take off the distributor cap and see where the rotor is pointing. It should be lined up with number one cylinder on the cap

About halfway down, you'll see that the cams can NOT be 180 degrees out. They line up with the seam between the cylinder head and cam cover, but the camshaft slot itself MUST be above that seam for the Intake camshaft and below for the Exhaust.

Look about halfway down that page you linked us to and you'll see the pictures. It's clear as daytime mud. ;)

That's the guide I followed for my head replacement and I've put 10k miles on the car since. Good luck!

Yes, I agree, once you know the slot must be above or below...but I didn't and that guide is the ONLY place on the web where you can find that information! Now if you go out and assume your front camshaft is the intake, when you clearly know that it is not, well yer just an idjit...and yes I am speaking to myself...

Yep, that's why I said "clear as daytime mud." you've got to know the "secret," but once you do you can't mess it up easily.
