My brother in law has an 01 F150 that decided to blow a spark plug out of the threads...apparently its happened before and was fixed, but now his mechanic says its gonna be over $2k to fix it this time. I found an 01 CV P71 motor and trans. for $400. I'm just wondering if the motor from the P71 would work in his 01 f150...the truck is also a 4x4, so I know the trans from the car won't work, but will the motor? Thanks

Any plugs we had blown out of heads were repaired by using Heli -Coils .In fact the police garage where one of my friends was a foreman used them successfully all the time in the motor bikes , especially the BMW bikes .

Thats what I told him, and he said his "mechanic" told him the heads need replaced amongst other things and the total bill would be over $2500. I told him F that I can find you another motor for a fraction of the price.

I know the truck's 4.6 takes a different intake than the CV, BUT if you're interested in salvaging the motor, the heads will run you less than $500 a piece. In their defense, if the plug he blew all ready had a helicoil, you can't really helicoil a heicoil.

I understand that you can't "re-fix" the helicoil, but if I can get him this motor for cheap, its just cheaper and probably quicker to swap the engine. I just need to know if it will bolt right up or if I would have to make "adjustments".

I just checked out replacement cylinder heads, AutoZone has several, but the replacement head part numbers between the CV and F series are the same, but as I said the intakes are different, so you'll have to swap them out. Technically you can keep the intake on the engine, but you may have to swap the PCM's and you'd lose low end torque.

Good to know. Mounts should be the same though?

CatSkinner

You'll probably want to hang on to ones on the truck, just in case.

Well too bad for him, he gave his mechanic the OK to purchase a motor with 165k miles on it and install it for $3500. He's such a douche.

I appreciate all of the replies
