so I've done two oil changes since I've owned the truck for about 2 months now and it still reads over full. Going by the manual the Windsor takes 5.5 quarts and I've also looked at the dipstick and it is a Windsor dipstick so I'm still dumbfounded. We're there different oil pans or dipsticks for the Windsor? It's a 1975 block and no it's not stock to the truck. Just confused in why it keeps reading the way it is when everything else seems to be the norm by looking at it.

 

Dipstick has an ID number stamped on it, post what it is.

 

The part number is:

D0AE-6750-C (Ford) B

 

D0AZ-6750-C .. Engine Oil Dipstick / Marked: D0AE-6750-C / Obsolete

1970/74 F100 302 // 1970/72 Galaxie/LTD/Fairlane/Torino/Mustang/Cougar/Maverick/Comet 302

1970/72 Galaxie/LTD/Fairlane/Torino/Mustang/Cougar 351W

No 351W's in Econolines until 1975. No 351W's in F150/350 & Bronco until 1981. No F100 of any year had a 351W

 

So im going say that since its a 1975 block its completely off on the right length, a bit on the longer end than it needs to be?

 

If it's a 351W from a 1975 Passenger Car, the dipstick would be D5OZ-6750-A / Marked: D5OE-6750-AA

1975 F100/150 302 & 1975/76 Granada/Monarch 302 also used this dipstick.

The thing is, your 1979 F100 never came w/a 351W, so finding a dipstick (and dipstick tube) that will read correctly will be difficult.

1979 F100 could have had a 302, 351M or 400.

 

Thats the main thing holding me back with the truck since the motor isnt the stock 302 and the PO did not know what the Windsor came out of. Was the car and truck Windsor different in terms of per say the oil pan or anything else fir that matter? 1 thing i know is that the oil pan bottom has maybe an inch of clearance above the crossmember thats there, figured with the different engine that was what caused it but not too sure.

 

351W:

1969/89 FoMoCo Passenger Cars: 5 quarts w/a filter change.

1975/97 Econoline; 1981/96 F150/Bronco; 1981/97 F250/350: 6 quarts w/a filter change.
