Got it! How about getting to the two bottom middle bolts on the valve cover on the driver side without disturbing the key parts? Tightening the rear one (by the turbo) it did fix the oil leaks. Any suggestions?

Thank you very much! Those disassembled pictures are excellent! It really helps to get my mind around on how it all comes together.

I am, not sure if it's minor, the pressure it's definitely lower after the oil change as the cap doesn't get pushed away when sitting upside down, but it's clearly visible and it whistles when it's open. I am thinking it's a good thing that the engine was rebuilt and maybe it didn't get enough...

Yes, there is a leak, a very small drip of oil coming there at the top of the turbo, where it's circled in red: I am thinking now that I have less blow-by pressure, that eventually should go away, it must be some residual oil from before. And I am looking to study the turbo in detail to fully...

Yes, there is only a puff of black smoke right when it starts, which I think it’s normal based on my other truck which does the same, and otherwise there is no visible smoke coming from the exhaust, it runs clear. I tightened down the accessible valve cover bolt and the oil leak stopped so far...

Yes, I am planning to open the turbo, is there any good video or instructions on how to take it apart? I have not worked on the turbo before I prefer to not reinvent the wheel if I don’t have too. Separate question, you mention the base gasket leak, which I presume it’s the “snow man” #8 in...

After cleaning the turbo area, it seems that there is a very small leak at the top, circled in red: Is that where O-ring #2 goes? EDIT: Typos

I washed the engine today and let it run for maybe one hour, the blow-by is still visible, but the pressure looks to be lower as the cap doesn’t get pushed away like before, when I put it upside down, now it just sits there and bumps up maybe 1/16”. I will give it some miles, hope it will go...

You read my mind, when I saw the leaks and the whole engine being black, I thought the pressure blew most of the seals and everything black is oil.

Ok, I will replace it with a regular one. I plugged that in just to see if the blow-by improved and I didn’t connect the vent lines. I was thinking that if the oil fill cap is open the CDR valve does’t have any effect as the blow-by would exit there without making it down the intake/ CDR...

Actually, there are only about 100 hours on the Tachometer, maybe it got replaced and that’s all the engine had after the re-build?

Aha! I was actually wondering why the engine is black and now I know, thank you! EDIT: I thought it was all covered in oil :)

Wow!!! That’s amazing troubleshooting! Yes, I did use a DWF CDR valve, only because that’s what I had laying around, and didn’t even think about it until now that you mentioned it. But, when I open the oil fill tube to check the blow-by , isn’t the CDR being taken out of the circuit as the...

Thank you! I am not familiar with the terminology, thought “snow man” was a typo after I googled it and didn’t find anything :) Got it!

Sorry, which one is the Turbo main seal, I only found this turbo diagram in the engine manual and it shows only one O ring, item #2: Is there another manual with expanded view of the turbo internal components?

How can you tell that it was rebuilt? From the RTV on valves seal cover?

Thank you! I feel more optimistic now :) I will pressure wash the engine and report back. Still don’t feel good about the blow-by, will do a video, not sure if it’s too much.

Oil pressure looks good and one interesting thing is that it doesn’t do the glow-plugs pulsing that my 1165A1 does, even as they were both built around the same time: EDIT: The alternator is working and the batteries are being charged.

Ok, so like many here I ended up buying a 2008 REV M1151A1 with 8k miles, initially for parts, but after picking it up, found that it had an IROAN in 2012 and it shows that the air filter was last replaced in 2020 at around 5k miles. The good news is that I was able to get it started and after...

Very good info, thank you! I did some more research on those codes and still couldn't find the meaning of EXER. (followed by date)
