Mack Technician

Folks from Maine seem to embrace the simple things. You don’t HAVE to love Moxie, but they choose to treat it like family.

Open season on computer generated accounts.... I once search a birthday girl because she seemed familiar, yup, it was a college basketball coach. Not sure what she was doing on BMT, or why she listed as an HVAC service. Coaching must have been her side hustle?

Check your fuel pressure too. I’ve had engine misses from low fuel pressure as the engine meets the threshold of stall-out. The cylinder on the end of the lunch line would normally be the first to suffer. Your already poochy running on 5 so you’d be none the wiser by observing engine power performance. Be sure to list your fix!!!

There's two fish in this picture. Mack's the little one who has very little to say about what direction they're heading. Sad, sad state of affairs.

I’ve found bad valves without digging too deep. Usually I pull the rocker shaft, let the valves close and pressurize the cylinder through the injector bore with a rubber tip blowgun. Be interesting to see how much blowby slippage you’d observe with pan off pressurizing cylinder. Wouldn’t stick any limbs in there while engine can spin from air pressure.

It’s really easy to drop the pan for a look and you’ll see any dirty secret.

You getting black smoke?

Be careful when putting cam roller followers back in, they’re ceramic. They can crack if you drop them into the bore and they strike the lobe.

You said in your first posting “#1 pump came apart and had a misfire”. Did the EUP (electronic unit pump) shed its spring? Is that what you called “coming apart”.

P.S.- I went through Mack’s engineering breakdown on CCRS base engine changes vs original E-Tech like your ‘01. It’s in the AI thread, page 5 (2nd comment) in reference to “ASET”. Google search “AI460 low power low torque” and it’ll take you there. Realize that it’s a buyer beware world, but the salvage yard should be given an ear full for doing that. Unless it’s a rinky-dink Mom and Pop establishment, or you failed to ask about its interchangeability, they’re responsible to know interchange. Good Luck 🍀 man!

You pull and inspect the roller assembly that drives below #1 unit pump?

I’m a few states away from my wiring diagrams, but follow the info stream. I was having a like issues recently, different OEM, and issue was an intermittently failing 30A power relay for a control module. Data would drop out, but allowed the powertrain to function and drive flawlessly and I also would have dozens of communication codes/errors when I’d link in with my laptop. I’ve never had the extra ground work, some must have. So long as you don’t monkey-up the wiring splice it can’t hurt to try. Monkey-up = scotch lock

Posterity salutes you!!!

This issue didn’t affect data retentions.

Same here. Steeler, your have a real humility that let’s you expose even your worst slip up. That’s huge. I’m still working on it. Someday I’ll tell you what happens if you forget to remove a camshaft installation shoe, but I’m currently still in denial.

On Gray engines or Red engines? That’s weird. Cracked or hole?

Your cam isn’t right either. The 6 injector pump lobes on the CCRS cam from ‘03 will not work with your old style pumps.....and you need your old style pumps to match your old style injectors...which need the old style heads. See the issue?

^ Yup, Trans wants to know engine RPM and can’t function without it.

IOW- IF this IS a wet clutch, only fill with ATF.

Would have been good to throw this situation into the mix before purchase. You accidentally bought an engine which is CCRS. Good news is it’s a better engine than your 2001( pre-ASET ‘02-‘03 is arguably the best E-Tech ever made), bad news is what your doing won’t work. CCRS makes multiple injections per power stroke, the 2001 doesn’t unless by some rare coincidence you got one of only a few CCRS that hit the production line in 2001. Does the old engine have an injector leak off line? IOW- look between the valve covers and see if a small “U”-shaped fuel line connects both heads. Then look at the front head of the ‘01 scrap engine and see if there is a little nipple for a line, just in front of the valve cover. Your new 2003 engine has spring loaded push tubes, does your old?

Besides Maine’s ice circles and sustainable Moxie.....Vets’ll get to stick jig pig-hogs. Impressive state record Perch just got iced. 2.2 lbs, 16 inch, little gal from Ohio.

Get a starting point anyway....

I once had an OHC engine break a unit injector top spring. When I’d start the engine the broken piece would start dancing around striking and shorting out the harness connection. It had that symptom only didn’t take minutes to develop. I’ve also had an ECM losing injector drivers for sister cylinder injectors simultaneously, 1&6. Again, not your case.

No active codes then may be injector cups.

Is the shifter a push button or stick? if it’s a push button simultaneously push the up and down buttons. I believe that will display the code one digit at a time. First it will give you a “D”, to let you know it’s into the diagnostics, then the code number “1”(if it’s the only code), or 2 if you have another registered, 3 etc. the four follow up digits that make the code. If you have a 2 digit display it will give you them as two digit increments.
