Ok so I just bought a 02 F350 with 200k on it 6 months ago. Couldn't pass on the deal... Couple weeks later I started going thru checking it out... Has oil leak down back of motor, not bad (maybe quart a week). Sometimes lil more... Oil on top of motor under fuel bowl. Icp sensor sipping oil out top( I assume that's bad!!!) the wire in ICP plug that should have 4.9.. Volts is dead....????? And just recently it's started cranking more than usual before starting??? I am not big powerstroke guy so need lil advice... Any help is good help... If u got anything I should look at let me know... Thanks

 

I would check the hpop for leaks. Could be the plug on the bottom of the hpop loose and leaking. If so I would give it some attention asap, ive seen them blow out while driving and loose almost all of your oil pretty quickly. And ya replace icp sensor if its leaking

 

Replace the ICP sensor.

Clean the valley and watch for the leak...

 

Ya I am getting ready to change ICP sensor.. I've looked a lil at hpop but nothing noticeable. I'll check it out again tho... Any suggestions about the wire or cranking?

 

Since the icp sensor is oily bad/going bad that could be the cranking issue...try to unplug the icp sensor and start the truck with it unplugged and see if it starts easier than with it plugged in.

Either way replace the icp.
