Glen I was sent this by mackcl96 Don't no how true it is cause I never seen one. Hello, Mack did a E6-400 in 89 Mack also had E7-400 90 Mack always said 350 tops on E6 but they wanted to see what would happen at 400HP before they stop using the E6 altogether. It was a probably a inside bet with the tech guys at Mack. I don't know how they made out but if it was not going to work they would have a E7 to save the customer. If your like me you never seen one but dosent make it so. They were few and far between if it did happen.

The serial no for the engine is stamped on the flat spot just in front of the fuel pump just above the top 2 fuel pump mounting bolts!

It is quite common to bore one hole I beleive there were actualy 2 thou over liners avalible at one time and you could hone the hole out to fit em if the liner slid in to easy.

the tp turbine fan is the same concept as the charge air cooler there would be almost no point in cooling the air twice!The tip turbine fan trickles off a little boost preasure to run a small air driven fan that is doing the same job passing ambiant air over heated boosted air same as the charge air cooler .WHY waste the boost.The only small benifit to the TT would be the short distance of the plumbing from the turbo to the inlet manifold vs the 6 ft of plumbing on a chassis mount.A chassis mount can be done to almost any engine in a vehicle. Also Im not sure cause I have worked for mack for most of my life but the first charge chassis mount charge air I saw on a mack came out with the E9 engine.I beleive mack used it first weather or not they invented the idea is another story. Up to that time no oneelse was using air to air it was always water to air.shortly after the e9 Every body started using the chassis mount cooler.

Its not that big of job to do just be sure you got all the parts.

nope its an addon no cam!There were alot of oil preasure issues with the j brake external oil line add ons yada yada!Some times bearing and oil pump changes. What problems are you having.

What ever ya do don't reuse the injectors with out having em tested that likly caused the failure! also check the injector hole for 2 washers!

350 is the max for e6

we have seen this happen with oil sensors as well!All out of warrenty A real bummer! Good luck with a policy claim.

You may have a brokren snap ring in the split cyl!(The bigger left hand cyl)The shift lid has an interlock pin that will hold out reverse if the spliter does not fully go into neutral.If you have to fiddle with the air shift to get an intermitant reverse this may be the case!loose shift rail bolt is another common thing. Go to the dealer and get a rebuild oring kit and tare into it ! The deep reduction is commonly locked out on the 12 speed meaning it will only work in first gear low high split and reverse.

I second that!

2004-2005 year pleged with problems by newer or older 99-2003

Youll likly nailed it with the injection line thing but remove the exhast manifold will likly confirm a wet hole!

Good info 68 we have had no failures of this nature even thou weve had sum broken bolts, but this is good info on the h ring Thanx for posting it!Most of our customers shut the engine down when the poping starts!

Glen That is all because they want the new teck guys to attend law school to learn to read the half assed gobaldy gook they write for the manuals theses days!That Insite program is awsume thou.Wish the mack guys had taken more pages from that book.

Sorry I cant help ya We do have the tool for install at work but have never used it!H rings have never been an issue.

do keep us updated! If you have one bad hole the blow by would puff back at you at the fill tube! If its a steady pume you may have another issue!If the engine is turboed it can be the turbo! I would check Glens theroy first if its asteady plume, a simple check!crack the drain plug in the morning see what ya see!

50000 was his intended target with shaffers oil!Having said that ,the oil he was using to this point was esso 15/40 the sludge biuld up is mostly because this is an egr engine!He went 5000 over his normal interval of 15000 miles.Intends to run chevron 400 for a short period then swap over to Shaffers next month.We,ll see!I hope I have convinced him to stick to a proper servce interval!I opened his eyes a bit wider by cutting into this filter.Oils in an egr engine really soak up carbon!the evidence is in that filter. That spiner is one of the best things Mack used since the inseption of the 4 valve e6! Volvo should have takin a page from one of the many good mack ideas on this one! They remove a whole lot of goo from the oil as you can see.

A WORD TO THE WISE This Is a picture is a spinner Filter from an AC 460 Engne If any of you intend on useing extended life oils ie: pensoil shaffers ect be very atentive of this filter! After 20000 miles the filter is plugged ,this guy was planing on a 50000 oil change interval .If any of you intend on extended intervals indend on changing this filter at least every 10 to 15 thou miles.

Well as long as its a runner thats all a guy can ask.Paint it gray now it will really haul a$$. Good job!

Your messing with the smoke control if you don't mind the smoke , you won't hurt it with that! 1 turn would have done the job!

It L run! But it will run better gray! At least 20 hp more too!

Wrong color!

Yup just center it the best you can the screw will be close enough!The degree spec is + / - 1 degree

Number one cause of fuel prime loss is any filters you have with plastic bowls on them on the primary side! Racor ect!If you have one of these on your unit by pass it and see if the problem goes away! Aside from that start at the begining check for loose fittings if the engine is vmac it has an orfice no leak off valve ,the primer Could be the problem but start with the cheap and easy stuff first! if it is a mechanical engine check the leak off valve, the spring may be broken.
