Is it true that the 5.0 engines have a similiar problem with the sparkplugs as the 5.4's do? i thought somebody told me but i do not remember. i am just curious, and friend would like to know also who has an older f150 with 5.0
Thank you

 

ive never heard that. the 5.0 has a reputation for reliability as far as i know.

 

oh ok thanks for the quick reply! yeah i dont know it was awhile ago i thought i heard somebody talking the 5.0 engines had problems

 

never heard of it

 

The Ford 5.0 is one of the most fuel efficient,reliable,Bullet Proof, V-8's that Ford has ever produced!........Back in the day I had one in my Box like Ford Crown Vic Police Interceptor, & you could never kill any of those motors! The optional engine was a 351 Cleveland that was a Pig on gas! I also had one in my 1989 Mustang 5.0 LX! Awesome Motor Period!..........

 

You must mean 351 windsor or modified because I'm pretty certain the Cleveland never came in the CV unless it was from 70-74 thats when ford offered the Cleveland..

 

You are probably correct, it was a 351, however with a Big *** Carb on it!........Possibly a 1991-92 if my memory serves me correctly!....

 

What you might have heard is that the spark plugs on a 5.0/5.8 truck equiped with a snow plow (or just very old plugs) become rusted to the cyl. heads and the porcelin usually pulls out or the plug gets striped on the head (cast iron of course), therefore requiring many "cursed sayings" and busted knuckles to remove them, and i've even gotten them out by using the old trusty "fire stick" on extreme cases. I have seen alot of those on the older trucks (not just Fords either) but they were all mostly plow vehicles. Oh, and the old Caprice Police cars, that was also common if they were a state cruiser and they used salt.

Just thought I would add a bit of my experience, if that helps you.
