Fitzgerald 60 series Detroit 12.7

It the engine tune they are using to get that 500 hp out of that motor. Had mine retuned and they told me at idle it was over fueling by almost 40%. After the tune no more smell burning eyes and no smoke on cold start. Didn't get any better milage but the smoke is gone and no more smoke shifting gears either.

 

Like I've said before. I know a few gurus. Message me I can pass the info. I'm just a driver so I don't know as much as I wish I did. Laptops are a must have now days.

 

Well got 60000mi on my new 12.7 that i replaced due to old engine blowing blue smoke with thick heavy clouds. The new 12.7 does the same thick heavy blue smoke burning 1 gal oil every 7k mi. When engine warms up it barely noticable but you still smell oil burning . Sleeping at night is almost impossible with oil burning smell . wake up in the morning your mouth taste like diesel. Not happy with Fitz or Detroit Junk IMO. Sad thing is nobody seems to know how to fix the issue. Can i get a compression check nope book doesnt call for it warranty tells us to go thru these issues step by step according to Manuf recommendations .

Sorry customer service sucks

 

How about paying for a compression check? I know it sucks but how else will you know.

 

Was it replaced with a complete stand alone engine or just parts replaced on original engine?

 

Replaced the whole engine . except bolt on parts water pump turbo ac alternator etc

 

Try American Fleet from Springfield,MO.I got an engine from them,they fix a lot of engines from Fitzgerald

 

Just got a quote from Freightliner for a Detroit remanufactured 12.7 long block .
21300 plus tax. If you don't have a decent core tack on another 7500.

 

So if you replaced the entire engine except for bolt on’s and you have the exact same problem the odds are probably good that it’s not the engine but the bolt on’s that are bad.
Possibly it may be the turbo..
The only other thought would be if you constantly idled both engines from the time they were new the cylinders glazed and the rings didn’t seat.
