E7 460 Jake Brake Oil Pressure Loss?
Joey Mack replied to longshipconstruction's topic in Engine and Transmission
there were a few updates to try to help the Jacobs 690 engine brake. One was a top oil line feed kit. If you see braided oil lines going to the jake spacers, then the update has been done. when you pull the valve covers to inspect, the data plate should have .021" stamped where the jake adjustment is stamped, old was .015 or .017... just curious, you can just take a pic of the left side of the jake spacers/valve covers. and the data plate on top of the front valve cover, or rear if they were swapped... then we can add more info.. jojo -

good call Onyx, Ive been in N.C. for 16 years, and I rarely ever need to pull out torches, and such, plus a million curse words.. I still anti-sieze every bolt that needs it... .. jojo
-
yes sir..... I believe it is a fuel delivery issue, and you make good sense.. I hope he doesnt load the parts cannon and fire it, however,, he seems to be diagnosing instead... jojo
-
ok.. I will look for you tomorrow...

I know... I'm from Maine... road salt kills everything.. may I suggest you spray them now with PB Blaster, and let them soak over night... any good pen. oil will do, then tomorrow use a 3/4" wrench and work them back and forth, with care... the lines are about $150.00 ea. only need to bleed 2 of them... pick 2 easy ones. ie: 2+5..... jojo
-
ok... now..... you opened the fuel lines at the head and bled off at least 2, right, like 'F' said, you pump the primer and pull on the line a little bit and bleed the air.. jojo
-
sorry, but I just want to be clear.... youre pump has the filter on it, right?
-
early E-Techs, But it is possible. In my experience it's the early ones... The one he has IMO was a better pump, just tricky to r+r the filter.. I welcome other opinions... jojo
-
I think we are posting too many possible issues. The truck ran , then it ran bad, now it wont start, is that correct?
-
Doesnt Bosch make the Mack pump? I know the primers are...
-
the last pump i bought for an ASET was $950.00 3-4 years ago...
-
i bet you have the fuel pump with the fuel filter on it? if so..... Bring a folding chair with you when you go to MackVo... you will need it... Sorry... Jojo
-
It is evil but, luckily all i had to do was remove the fuel hose at the primary filter inlet and tank then pull the tape out of the tank, then fish out the cardboard tube that was the middle of the roll..
-
could be.... many years ago I chased a problem with hard starting and rough running, and after a few days, I found electrical tape in the fuel line from the tank to the lift pump.. someone ( dissgruntaled Employee We thought) anyway there was a roll of electrical tape in the tank, once the glue dissolved, well....... now you have mile long snake... sad thought's but possible... keep in touch.. jojo

operating pressure is between 60-100 psi.. did you crack a line at the head and pump the primer till it leaks of, air will bubble out first.. then lock it back down, 2 lines will be enough to get it to fire...
-
its about time....
-
blown head gasket? no loose C.A.C. boot's?
-
it kick' a$$..
-
heck I have even spent hours looking at an issue, only to find a bad fuse or dirty fuse socket... it happens... like I have said before.... 'not an expert, just joey mack'...
