I know I'm running a dinosaur and do not expect much response here, but some might find this interesting. I discovered on an RV thread where someone has come up with a post HEUI pump filter system that will save your injectors from shrapnel and having to clean out the oil galley; Injection...

I'm thinking it's time to rebuild my C9. Looking for any good experiences with this or even someone who can install a reman long block and do a good job and effecient. I remember reading about a shop somewhere in Florida?? that did rebuilds on 3126's but can't find the thread now. Anyone advice...

Sitting at a light, the temp shot up to about 230, eng protect lite on, shut it off, checked under hood, nothing boiling, full of coolant, fan spins freely, belt in place. Got in, pumped brakes to remove air in tanks so to engage horton fan clutch, started up and put it at high idle. Temp...

Not looking for the "should we or not", but rather, looking for DPF experiences, good or bad. Hoping to gain pros and cons on retrofitting current truck (C9 M2) or go with a new/used ST8 built with DPF from the factory. Any opinions on most reliable motor/trans combinations appreciated. Anybody?

My genny was included and did the recall myself. The fuel tube can be reached under the front panel (outlet end). Reach in and release three small white wire harness plugs and this allows you to reach the tube. Mine had the hose clamp poking a nice little hole in the adjacent tube after...

I appreciate the thread on reefers and CARB, now let's talk truck motors. I heard on Landlinenow that CARB is declaring August as Green month with the inspections set up at scales to "educate truckers", read....check emissions compliance by running a sniff test etc. (and, oh, btw, CA DOT will...

Problem is a small amount of red coolant showing up in my fuel water separator for the past 50,000 mi.s....probably an oz. of coolant every 2000 mi.s. The coolant recovery tank finally showed up today with one drop of fuel floating on top the coolant. Not enough in the bottom of the fuel tank...

With my C9 on the down side of 700k mi.s, it's time to think about being proactive on replacement with the least amount of downtime. I'm hoping to get 1,000,000 out of it, but I realize I may be dreaming. Despite what others may think about this motor, I've been very pleased, runs smooth...

Any problems changing back to mineral from Synth. Have heard it creates problems in gas engines, may be old wive's tale or different for diesels? Reason being, oil pressure seems too low on my Cat C-9, around 37psi at 1500rpm cruise and 15psi at idle when fully warmed up. In a pull up a...

2007 M2 345,000 miles, switched to mobil synth 75-90w rear end grease about 100,000 miles ago and now I believe a pinion bearing is going. Noticed a whine in the rear, checked grease level, looked good, no noticeable metal on the magnet, but the pinion housing is getting too warm to the touch...

OK, question is, can anyone tell me the Valve Lash gap setting for a 2007 pre-emmission Cat C9 ACCERT on a hwy use engine in my 2007 FL M2106? I've been looking online to no avail short of buying a complete service manual. I'm big on DYI, how hard can it be? Any help much appreciated...
