Bought my 1988 F150 4x4 Xlt Lariat 300 a few months ago, have replaced a ton under the hood.

Distributor, cap, rotor, plugs, wires, various sensors on the engine, inline fuel pump.
Probably more I just cant think of them right now.

Question is, what else should I be worried about? /seeing as how I'd like to put this truck on the road soon.

Thanks!

Check the heater hoses,radiator hoses, and the fuel pump relay,and the ecm relay they are
Located on the driver side next to the air filter box.

I forgot to mention that as well. I actually replaced heater hoses and radiator hoses. And serpentine belt. Fuses seem to be ok

Those to relays are the only thing else i can think of.

Keep at least one spare relay in the glove box, and you could try switching too a synthetic, DIESEL RATED oil like shell rotella t6, these motors like the that. The distributor mounted ignition module has been known to die at random, so carrying a spare, and a module wrench isn't a bad idea. Those are my tips from 20 years of tortured 300s.

When I replaced the distributor I replaced the module as well. Thanks for all the input. Ill be sure to grab some of that rotella. Actually work in a diesel shop lol so that won't be a problem

So now the valvetrain sounds like its dry. Can anyone help me out here?

Hows the oil pressure?

Crowder

In the center of the gauge. Haven't checked with an external gauge.

What oil and filter diid you use? You
Might have trash in some of the lifters?
