Should I buy a 2008 GMC Yukon with blown flex fuel engine

Asked by Jun 09, 2016 at 12:07 PM about the 2008 GMC Yukon XL 1500 SLE-1 4WD

Question type: Maintenance & Repair

Just looking for some advice. I know the owner of this fully loaded Yukon. It
has the bad engine and would need a new/used engine installed. My
question is should I do this. I've read that you can plug in $200 chip that will
keep the engine in V8 mode and will disable the AFM. I don't do much
driving so having a big ride would be nice for the little driving I do. I'm told a
used engine installed would be about 3-4k parts labor. I can probabaly get
the Yukon for about $1500. Thoughts? Advice? Thanks!!!

125k on the yukon right now. Thanks for your input! I know the current
owner of the Yukon and I know the mechanic that is quoting me the 3-4k
for engine/labor numbers. I'm just curious if this is something people have
had success with given the poor performance and reputation of these
engines.

new tires last year, no engine currently so tough to say how the rest would
be, but your right, it's a gamble. I'm just attempting to mitigate risk if
possible. I've looked at websites that say their used $2,800 engines have a
5 year warranty....but curious what that really means. I'm also curious if an
engine with higher miles would be better than one with low (rationale being
that lower would have yet to experience problems while higher mileage
would indicate engine will not have these issues?)

Man I'd do it, it is still worth a fair amount, look into crate engines you might get a good buy and it will be new, the engines themselves seem to be pretty good, it's the other stuff that causes the problems like the AFM system, the only real detractor on this is the transmission, if you do decide to do this I would seriously consider overhauling the trans while the engine is out.
