Like greasytshirt said I personally have never seen an oil cooler fail internally. Many leak externally but never a internal. Multiple headgasket failures though. Possible air compressor, but then again I have never seen one fail. How was the sealing surface of the block. They have had failures...

I had some new info pass my way, the tech I work with has had 4 re-seal comebacks all with high fuel pressure faults related to the burner. I made a call up the chain and found that this is not an isolated incident. Apparently when setting the fuel pressure with DX2 (dealer software) it is 5psi...

Question... have you had your atomizer re-sealed recently?

Had a 08 338 today with a hellacious turbo flutter. If you, in drive stood on the throttle and let off quickly it would badly flutter. I removed the cac hose and grabbed the throttle shaft. There should be almost no play between the butterfly and shaft. This one was flopping around. I put in a...

Im not sure you would ever see fuel out of that hose unless the truck was in a scr warm up or performing a regen. There is a test you can perform in which you, remove the line from the nozzle, place it in a graduated cylinder, command the atomizer on and measure the fuel delivered. This would...

A P141F is a generic code set in the ECU for a burner malfunction. You need to retrieve the code from the BCU, and a generic handheld scanner in most cases will not communicate with the BCU (burner control unit). There are a series of tests you can run with the DX2 dealer software that would...

Its hard to say how many miles. The burner system usually will usually de-rate a 10 bars in the meter. If you can perform a manual re-gen when the bars reach 3, you can buy yourself a little time. Make sure the bars in the meter go to zero. As a general rule a truck will do a re-gen approx every...

P141F is a generic code that sets in the ECU, It basically means you have a fault with the Burner and will set a code in the burner control unit (BCU). It could be anything related to the burner system, the only way to tell is to have the code pulled. I doubt you pinched a wire in the cover I...

Thanks guys. I gave up social media and usually find myself doing online training of some sort or another in my spare time. I stumbled across this site while looking for info on a Hino/Denso fuel pump. I know first hand how hard it can be to find info on trucks. I thought that greasytshirt was...

Yeah looking at that littered burner event log and the multiple issues it was showing its plausable for sure, we had one crack a few weeks back. I would guess its a 1-in every 400 kinda failure. I have only seen 2 personally but the other guys have seen some as well. To answer your other...

Salesman at my old job..."There's an azz for every seat":)

Had a similar situation today, cust bought a used truck and brought to us to diag a engine light/ oil leaks. I spent a lil over an hour diag and made a 2 page list. Truck needed a little bit if everything. Rusted out fuel tank took out the inj pump and injectors. Basically a complete fuel system...

I pm'ed you. Wen you say Burner is broken what exactly do they mean. Is the Mantle broken or is the Filter cracked and passing soot?

Would it do a manual regen if you pressed the regen button? If you pm me your vin I maybe able to look at the old Burner event log, and codes from the first time you had it in. As greasytshirt stated this is a hard symptom to diagnose without having raw data to observe. You say they replaced the...

I have been working on Hino's for 30+ hours a week for almost 10 years. I have replaced 1 water pump for a coolant pushing issue, I cant count the # of headgaskets I have replaced. It could also be Injector cups but.... I always replace the cups when I replace the headgasket. I know you...

Any codes? How fast can you get it to go? How long does it take to get up to top speed? Do your brake lights stay on? Did this slowly start to happen or just happen all of a sudden? I have seen lots of issues with the older JO5 engines. How many miles? My first thought is turbo starting to...

Thats what I suspected they might say. I think you may be right in looking into-another high volume dealer. The fact is that required training for dealerships is expensive. The larger the dealer, the more tech's that are required to be certified by the OEM. The more certified techs in the dealer...

Yep you or I can look it up, just need a vin. I look up Penske trucks all the time. They bring em after they clear the codes, then I look in Past work info from the portal and see what they have done. You can also look at any tests rhat were performed as well. Oh, and I also had another truck...

You may have had 2 fuel leaks, the line being the most obvious, and maybe the atomizer was a smaller leak. Sometimes they can be trick to diagnose as there in an area where there are multiple place to leak and they can be hard to see. Im my personal experience most techs want to fix it right the...
