351 Ford engine

Anonymous-0 · Oct 29, 2012

Have Ford truck with 351 engine starts good sounds good,no smoke until it gets warm,Then lots of gray white smoke.Anti freeze level stays good.BUT used 4 qts oil in 90 miles.Why not BLUE smoke ? Any ideas greatly appreciated.Thanks GP

351 Cleveland or 351 Windsor??? As for the smoke you maybe see if wrong since gray and white are close to each other. How many miles does it have?? What oil do you use etc etc

Are you sure you don't have an oil leak?

And to old's question 351 C, W, or M and year?

I tore down a windsor once with a hole in 3 pistons. could be.

Try valve cover gaskets. The family, the mileage or the brand doesn't make any difference. The thing's leaking oil.

Did they put a Windsor in a truck?
I thought it was only Clevelands in trucks and Windors in Mustangs, etc.

I can not say but then who knows what may have been done to one over the years. I knew of a 1957 Chev that had a ford engine and transmission sitting in it

im guessing a windsor and the intake manifold is leaking coolantwhere it meets the head,as coolant dont go thru the intake on 351

the 351C was only in cars, I think about 74 was lastC, then M was in cars and trucks, ,I think 80 pickup was last of them, the 351 W was used in cars and trucks from 69 until about 96 in trucks, forget when the last car had one but I think it was maybe a 91 police car, but might have been replaced sooner than that

id you read the man's post before responding? no answer necessary! "Anti freeze level stays good.BUT used 4 qts oil in 90 miles."

sounds pretty normal for a C or M engine with over 100k on the clock...400's were the worst oil burners...i dont recall any 351 C or M's from factory in trucks but they will bolt in to replace a 400M.
year,model would help diagnose what you have.

Could it be a bad PCV valve?

Have a 1981 F350 that had from the factory a 351M

Now has a 460 and is much better for it !
