I have a 1999 RV with a F53 chassis.

It has a V10.

I found a torque spec (on a Ford site) for the spark plugs on the web saying 160 - 168 inch lbs.

I then contacted Ford and they said 71 - 106 inch lbs!

So ..... what do I do? Both answers are from Ford but which is right? Does anyone have the correct torque spec for this engine (early single valve V10)?

Also, I want to confirm the gap .... I "think" is should be .052 - .054 or .056

Thanks ..... Mike

 

OP has multiple threads on this but appears to be getting answers in the Super Duty forum.

 

Sorry, just didn't know where to put it ... didn't know if the F53 should be posted as a super duty or large truck or ??? Although I had used this forum for my old F150, I didn't know there was a V10 area.

Not to worry, looks like the Super Duty folks are on it. I know some of those heads are fragile, so you are correct to ask and ask again before swapping those plugs. Good luck.

 

This is our "baby" ... when I met my wife, she had never traveled. She was paralyzed from the shoulders down in a diving accident when she was 12 ... she is 37 now. She needs care ever 4 hours. When I met her I got the idea of reworking on old RV so I could do her care while we are away from home. Since medical items are so expensive, I designed an built my own lift, cut a new door, gutted the inside, built a personal lift inside and them installed a hospital bed on rails. They wanted $25k just for the outside lift ... I only paid $18K for the RV!

Here is a link to some pictures of the project: https://mcsele.shutterfly.com/2299

Because my budget it always "tight", I try to get all the info I can before tackling a project.

Thanks again ..... Mike
