Thanks for the info. No timing belt, eh? Hmph, that does save some money then.

Ok, all fluids and filters have been changed regularly since I bought it, including the tranny. I still need to have the chassis lubed. I replaced the shocks and steering stabizer and all 6 tires have been replaced and balanced and air pressure is maxed out. Pretty much everything that is standard maintenance has been done except the plugs. I haven't changed the O2 sensor, but don't know enough about them to change them before the code pops that something is wrong with it.

Now, about the plugs, I have them on hand (Autolite double platinums - any suggestions on gap?) but haven't changed them because I can't find where they go. I've looked in from the front and the rear of the engine and just don't see them. I assume I need to remove the upper and possibly lower intake to get to them. Is that correct?

I knew there was a reason I keep hanging onto my 78 F-150.
