OKay so I guess you guys have already figured out that this post is about the 3v engine. My question is, what is the best fluid to spray into the chamber where the plug is to get it free. I've heard PB Blaster, Carb cleaner with carbon dissolver, and a couple others. I just want to know the absolute best. What you guys think?

 

I love PB blaster, my favorite

 

cool, also, which company makes the best one piece replacement plug? I found some by Rousch online and they look like they would be good plugs, but are they one piece?

 

Pb blaster. Spray them. Back them out. Run them back back down tight and keep doing thid untill they come out.

Service Procedure - Removal

Tools Necessary:

Thin wall 9/16” spark plug socket, various length extensions and ratchet. (Do not use a standard deep well socket) Beam or dial style torque wrench, (non clicking type). Carbon dissolving carburetor cleaner. Compressed air and blow gun. Shop Vacuum. Nickel Anti-Seize.

IMPORTANT: You MUST adhere to this procedure exactly to prevent breaking spark plugs during removal! Engine must be completely cold (room temperature) before beginning.

Spark Plug Removal

1. Remove coil on plug assemblies and set aside. Using compressed air and shop vac, clean spark plug wells of all dirt and debris. 2. Using a ratchet, back out each spark plug 1/8 to 1/4 of a turn. Fill the spark plug well with carburetor cleaner to just above the hex on the spark plug. (½ to 1 teaspoon) (see illustration #2). 3. Allow a minimum of 30 minutes soak time for the carb cleaner to wick down to the ground electrode shield and soften the carbon deposits at this time.

NOTES: Review the product label on the carburetor cleaner and adhere to all precautionary statements. Use at room temperature with appropriate PPE, (personal protective equipment). 4. Tighten and then loosen the spark plugs working them back and forth to remove. Use the beam style torque wrench and do not exceed 33ft. lbs. removal torque (see illustration #3). If more than 33ft. lbs. is required; place an additional ½ teaspoon of carb cleaner in the well and wait another 15-30 minutes for the carbon to dissolve. 5. Repeat the back and forth effort working the spark plug loose. Some screeching and high effort will be noticed. Remove the spark plugs. 6. Using the shop vac and a small hose, clean out the plug well and combustion chambers of excessive carb cleaner.

WARNING: Excessive carburetor cleaner in the combustion chamber can cause the engine to hydro lock, remove as much as possible.

Spark Plug Installation 7. New plugs should be installed using a thin film coating of high temperature nickel anti-seize on the ground electrode shield. DO NOT coat the ground strap. (see illustration 4) 8. Tighten spark plugs to 25ft lbs.

 

I'd say to use plastic explosives........at least it'd be more fun, and relieve some stress!

 

Use Motorcraft SP515s. They are the updated version of the two-piece plug. Coat the plugs with antiseize like shown in the picture above.

You do not want those Champions in your motor.

 

Anyone tried impact gun??
I have watched the Youtube Vids on guys getting all out without breaking.
I have NOT been able to find an example where is didn't work

Have you guys seen working or not working??? (not a friend told me his friend... lol)

 

Yes, I used an electric impact on mine after letting the plugs soak in PB Blaster for 24 hours. No breakage:
