    Just last week our 08 F350 developed a hole in a piston. Are these rebuildable? Is a salvage yard engine our best option? Any good sources for used engines? We've looked at car-parts.com. Need to get this back on road asap and looking for best options.

    Anything is rebuildable, just a matter of it being cost effective to do so. This would also be the most time consuming option. Crate/reman engine should be most reliable plus you get warranty. Used motor is a crap shoot, being able to see truck it is coming out of helps. But both of these would be the quickest to get truck up and running again.

    I'd rather rebuild than pull from a yard. You never know what you're getting into.

    Either way, before you slam an engine back in there, figure out why you are running lean and burning through your pistons.

    The rear 2 pistons made contact with the spark plugs. Not sure what was going on there?

    That would indicate a timing issue. The ford timing chain tensioners are good about having the plastic wedge on them come off on higher mileage engines which leads to a lot of slop in the timing chain. Not a good scenario in an interference engine. payup payup

    No. Not a timing issue. A dropped spark plug issue.

    Dropped plug? And now the rest of the story. We just purchased this about 3 weeks ago, 95k mi. Had a very slight miss when test drove. Put on a scan tool and no codes. Rear 2 plugs n coils were just replaced, figured another coil bad? Drove home approx 200mi. Got worse and now check engine light on. Drove directly to shop that works on our trucks. Missfire #10. One of the new ones. Brought back to our shop. Took out #10 and it was slightly bent. Replaced all plugs w correct motorcraft ones, did have autolites. Also replaced other 8 coil packs. Ran great for 200 miles then with out warning blew up. I should have dug deeper when we saw plug was bent the first time. This is our
    3rd v10 n a fleet of 11 trucks.

    Sorry man that sucks. They probably taped to.hole to far down or the wrong plugs

    I meant a plug fell into to cylinder or a plug that went to deep into the head

    Yep. This.

    As for rebuilding vs quality reman? You "might" save a few dollars rebuilding, but if getting back on the road is the priority then a reman can be at your door by noon tomorrow, and installed by midnight.

    When I managed a repair shop, we used ATK, and Jasper for remans. Only one bad one in probably 100 or so over 8 years.

    Sounds like yo got scammed. Did you buy at dealer or private seller? Damage to top of piston will cause a "hot spot" and eventually burn through the piston.

    Would poor maintaince lead to collapsed lifters and floating valves?

    You engine doesn't have lifters per say.
    But it's hard to say.

    Just did this last spring to one of our employees trucks. I found him a Motorcraft crate engine. Long block so very little needed transferred one engine to the other. 3 year unlimited mile warranty if I remember correctly. It was around 3500 for brand new. If you consider downtime it'd really not bad. Where are you located? I'm in central PA if you aren't way off and I can hook you up with my parts guy.

    I second the Ford reman. That's what i did with my 2000. 900 mi before the warranty expired, I spit a plug and Ford replaced the head under warranty.

    A ford reman would pry have been the best choice. We are getting this one rebuilt. Should have it back next day or so. New top end, tensioners and one new piston. Tyhe claim one of the intake flaps broke off and damaged the spark plug/piston.

    I wouldn't trust a junkyard motor. It may look good outside but maybe damage internally no way to find out then to take it apart and by then you are at where you are now with the original engine
