Tune up questions
1994 F250 460
I'm looking to do a tune up on my truck. I'm fairly certain it has the original parts still. I want to change the plugs, wires, cap and rotor. What brand parts should I use? Motorcraft? Should I spray the plugs with some pb blaster the day. Effort since they're probably 21 years old?
Also, my Haynes manual lists a range to torque the plugs, what poundage should I use?
I haven't done a tune up on a veh in over 20 years but I feel confident in doing it. I'll just go slow and do 1 item at a time.
Thanks, Jeff

Thanks snopeston, that was easy to find. I unplugged it and some dust fell out and it looks pretty corroded. I added a motorcraft one to my shopping cart. I think you guys just saved me from a catastrophic failure leaving me stranded in the woods. This is my camper hauling truck! I should probably replace the wire too.

Good luck, the plugs on my 5.8L were a challenge due to corrosion. Patience, a long extension and swivel can be your best friends...

Easily the BEST cap/rotor is the MSD stuff, most off all with the retention cap. $35 bucks or so for the cap, rotor, and retainer, not bad at all.
I can't seem to find in a quick search an actual rating of the resistance of the Ford Racing wires. Not a good sign and a forum post said 1000 ohms/foot. I have no idea why anyone would buy these. For $20 more you can get the simply awesome wire that I've never read a single legit complaint about and is only 40 ohms/foot. The Taylor Cable Thundervolt 8.2s.
Plugs, this one people will likely flame me about but for a decent running injected engine I'd put in the Bosch Platinums, the plain ones. They don't degrade like standard plugs and the Bosch design of covering the side of the electrode keeps/makes them work fantastic for a very long time. FWIW I'd never put them in a carbed or poorly running engine, platinums fowl more easily.

I have no idea why so many people on here are always about the motorcraft/ford parts, it's like it's a religion here.

I havent tried the Taylor wires, but i also haven't spoken to anyone that has had a bad experience with the Ford 9mm wires either.

I do, they're good quality parts. You get what you pay for, especially when it comes to auto parts.

I dare you to hold in your hands a motorcraft and MSD cap and rotor kit along with the receipt for both and choose the motorcraft. Motorcraft vs. cheapo Brand X, sure you have a point, but that isn't an argument for motorcraft over MSD.

Yes, tried them in my old 95 F150 with the I6, current 95 F150 with the 5.8L, and my old 2000 F150 with the 5.4L. Ran like poo...put in Motorcrafts in, with all things being equal and ran like a champ. Also tried them in my 89 Wrangler...it got Champion plugs after a month of chasing idle issues...
If they work for you, great! But based on my past experience, I wont use or recommend them...
