We need to change the plugs on this beast. Any tips from the pro's on here?

I know they have been in there awhile so I have planned on new wires and then to also spray some WD 40 around the plugs before doing the job.

 

Use a good penetrating fluid (PB Blaster or similar), not WD40 (moisture dispersant)... Philip

 

Ok, thanks for the tip. I have some PB.

 

I'm not sure what you're looking for in tips. The passenger side plugs are certainly easier to get to if you jack the front up and go through the wheel well (even easier if you remove the wheel first).

Another good tip. Thanks!

 

i have never done a SOHC but on both my OHV 4.0 and 5.0 v8 it was best to do them from the wheel wells. jack the front up remove the wheels and liners bam 30min deal.

goodluck!

 

I always remove the intake tube and do the plugs from the top on both OHV and SOHC. Since the tube is removed anyway its a good time to clean the MAF and the throttle body while your there. Little tight on the passengers side but I never had any real issue even with my big arms. I never ran into stuck plugs even on the plugs that were never changed before so I do not not spray the plugs prior to removal. I always change plugs when the engine is cool. (under 100degF) On aluminum heads the plugs will probably squeal some upon removal especially if its the first time changing the plugs. For aluminum heads I like plugs with the nickel plating but always use a dab of nickel antiseize regardless of plating or head material. I always use single platinums on my own vehicles and change them every 50k miles like I do for modulars. A little premature time wise but you can avoid issues this way and do not keep the plugs in the heads for excessive amounts of time. I always use a 3/8" ratchet for removal and tightening the plugs as a torque wrench is impossible to get in the tight quarters and achieve an accurate torque value. If you have a problem get the plug started use a piece of rubber hose slid over the ceramic of the plug.

 

Thanks for the info! I do hope it goes well.
