Timing job
I have to remove the timing cover, to get a bolt out. I’m doing the timing chain and gears since it’s $30 for the part. When I do it I have someone to help me. I will set it to TDC before I remove the parts and install them at TDC. Do I have to time it at all and remove the SPOUT connector? The thread on it reminded me of that. Or will it be properly timed by removing and installing at TDC?

The way you described, when the motor is not used for TDC, no need for the SPOUT to be removed. You will need to set it to 10degrees BTDC when you finish and the spout will need to be removed. You should use a timing light to do this and they are cheap or you can rent one for free from the Parts stores I think.

That's correct. When you remove the SPOUT and set it to 10 degrees that is called BASE TIMING. When you finish setting it and put the Spout back in the PCM takes over the timing job and automatically fluctuates to meet the timing for ALL driving situations.

It's easier if you watch a video on How to set timing on a 199 ( use your year) Ford F150.
After you watch it then any questions you have will be easier for you and the forum to help.

You really should not have to retime the engine with a timing light after replacing the timing chain and gears (as long as you set them straight up)
You could do it for GPs and pat yourself on the back, but if the truck goes into a dealer for timing chain and gears replacement...
That is all they will do, They would of course road test their work, and if it pings or ran poor, then the tech might consider using a timing light to set base time

The 10 degrees advance is done at the distributor
The timing marks at your cam and crank gears are just dots that you line up with the chain
So, changing the chain and gears does not really affect it unless it was loose as a goose, and someone timed it with the real loose chain
All the ones I have had to re-time over the years... After setting the timing correctly, I see the mark where the factory hit the distributor with a chisel
And the marks line right back up

Not sure what exactly was done to the truck. but the timing and the spout disconnection are critical
The cam timing gears and chain are idiot proof, well almost, I have seen pros get them 180 out
You just make sure if you do time the engine with a light when you are done, that you have it operating temp and the spout out
They call it cookbooking
We all started out knowing very little and cookbook with a service manual is the way you learn
I would assume whatever was done to the truck was done correctly until you have problems
I can post the manual pages for the gears if you need

If the parts stores loan the tool I have a store 5-10 minutes away. I’ll just take it there and see if they’ll let me check the timing in the parking lot, with or without loaning it. And then I’ll just bring it home if the timings off. I figure it has to be at operating temp anyways so it shouldn’t hurt to drive it 20 minutes at most there and back.
