    hi guys,

    i got the opportunity to possibly buy a 2008 ford f350 regular cab truck with the 5.4L SOHC 24-VALVE V8 in it and was wondering if any of you have one or know about them and can tell me if this particular year and engine have any problems outside of the whole spark plug changing deal. any help would be great i see mixed reviews online.

    thanks

    The Triton engines had issues with SPITTING OUT spark plugs before '04 which is what you're referring to. From '04-early '08 the Tritons had basically the opposite problem with spark plugs where it was nearly impossible to change them out without them breaking off in the heads, which is what the OP was referring to.

    My understanding is that this problem was finally fixed at some point in 2008 and the easiest way to check if you have the old type of heads or the redesigned ones is that the old ones have black boots, the new ones have brown boots. If you have brown boots, you should be able to change your spark plugs without issue. Black boots... well it seems like a process, though they did put out a cheap aftermarket tool for removing the broken off spark plugs from the heads as it was such a common problem and very expensive to have the dealership do it for you. There's a link below on the topic:

    Aside from the different spark plug issues that plagued the Triton engines (which are a little ridiculous on Ford's failure to correct them quickly), they're actually pretty good motors in my opinion. And 9,000 sounds like an ok deal to me, not so cheap that it would scare me off, especially if it's just a strippy XL. Around here, you could probably get a regular cab XL with 100K miles for a little less actually. Best of luck!

    we have had no issues with our 5.4s, but they are pretty weak for a 350

    yeah i'd have to check if its just plugs i'm not worried about it its a stripped XL model with a little over 100k on it looks super clean it would be a work truck so i'm not looking for bells and whistles......i'm surprised its not sold already actually as blue book is around 12-15k and this is in good to very good condition.

    I have an 09 F250 with the 5.4 with 20,000 miles. No trouble and pulls trailers fine IMO.

    I would look for a v10. Plenty of them on CL with around 100k in DFW. Alot more pulling power and about the same mpg. Also a very proven engine that is still manufactured in the 450 and 550's. I think they had to change the engine in the smaller trucks due to EPA issues.
