What's the difference between the ASET, AC and AI engines...? Ac is tractor AI construction truck two diffrent egr concepts! you need AC.

All external problems ,exhast gaskets, turbo problems, coolant pushing problems! most of which have been finally cured BUT has your prospect truck had all these up dates???? That would be your worry!The later 2005/6 trucks mostly had exhast gasket problems the fix is spacers and update gaskets you got to know what to look for! maybe you should take the hint move up to 2001 or past 04 to 2005/06 Or stay put!!!!

My guess would be the throtle lever is broken try replacing that first!

I agree with Rob here replace that HL switch somthing told those relays to shut down All at once ,that relay arangement,(The Update} was ment to take the load off the HL switch, Maybe it got installed a little to late to save the switch!

Hope fully exhast gaskets only! Don't kid yourself they make most of the money off the parts and what they swindle out of the dealers! Not offthe sale of the truck!

If you inframed it and did not remove the fly wheel yo may be ust getting a dirty flywheel sensor!

I Just didn't want to say it! Its a truly bad Business move if thats their plan! Just makes us all look bad!

Thats disgusting !Some one droped the ball on that one!

The codes sum for the newer stuff are posted here ! http://www.nortrux.c...hp?area_id=1003

Anytime!

Check the Codes out on this site! http://www.nortrux.com/index.php?page_id=1033

Line goes to the blow by ent on the top of the valve cover normally!

Amen to what HK said! Two peice is the way to go buy the eaton aluminum one Smuther it in grease when you install it and set the clutch brake right at the floor level and it will last ya a life time!,

The most comon failure of the e9 head was droped valve seats I only ever seen one cracked one.The weak point is the head bolts lower corners of the heads external leaks.The gasked usually gives out due to broken bolt.

If you go to this site http://www.mackduds.com/patsyandshane.htm and scroll thru the slide show there is one picture of it! Quite the sight! Its to bad they invested so much time and effort and never took it to production.

You pretty muck got to give us the code before we can make a call on this!A road speed sensor will cause the light to come on! is the speedo working?

Yup in the 80s the kt was offered in the superliner It put the front axle up to almost over weight empty on a road tractor.

If it were mine and I used it as much as you do I would be doing the same thing As 68 has stated liners are the likly culpret! run it for a bit more and drain off the goo you have put in the rad flush it and restore it to proper coolant and get on with life!Ive been tempted to try this stuff http://www.rxauto.com/index.htm if it leaks agian phone these guys and give it a try.they garrenty it or your money back.

easy same gasket as long as the e6 is a 4 valve engine

With the cab up and standing on the pass RH side look behind the fuel pump if you see a bolt on plate that the turbo drain tube goes to its an E6 If the tube bolts directly to the block with 2 bolts its E7.

Check the yoke bolt for tightness

Nope I would not recomend that on any of the new engines These new engines have enough problems with out poeple tring wives tales on them! you don't know what you'll do to the dpf, Great big crap shoot to many things to be upset by tring an experiment! Injectors are only one part of the system. to much else going on here! Don't do it.

after checking the odvious ! Try unpluging the green sensor on the condensor coil and jumping the plug at that point if that releases the fan your problem is that switch a very comon failure!Same at the ater rail switch jump it out see what happens!

Just a side note on the turbo change ,May have been an OK and justifide preventive measure in light of what has happened. BUT would not have been the cause of preasure loss in this case.

Its not totaly unheard of for the pump drive to fail, I doubt the crank is bad unless you or he ran it longer than stated ,with out pulling caps down he won't know, the cranks are heat treated and have a blue tinge anyway.A turbo failure will not make the oil preasure go away . till all the oil in the pan is in the muffler! The puter turbo codes would not be related in to this Failer . The engine would or should have shut down on low oil preasure that would have and should have happend to you at least once on the way to his shop ( Asuming you drove it there).DID IT!??? If so I doubt the crank is bad yet! Just another opinion take the truck out of his shop to a dealer that knows what their doing!The key here is the Unnessary turbo change with out due cause .He should have pulled the sensor and checked the system with a real gauge before doing ANYTHING else, to confirm the problem, Not depend on a computer code for info. Finding the root of the problem first ,when a pump drive fails, usually two things happen no oil preasure and compressor won't pump. Just an opinion
