Thanks for the continued research!

Thanks for watching

Thanks for the update!

[@NotSoGrandGarage]

No problem. Thanks for watching

[@antoniosestar3671]

Hvala!

[@NotSoGrandGarage]

Appreciate it

Im optimistic that it was just the coolant burping itself to get to correct fill level. How about a compression check or checking for combustion gasses in coolant? If you have the time, that would be another good video.

[@NotSoGrandGarage]

Yeah I've thought about snagging a bottle of the diesel specific test fluid... we'll see.

[@BRWfilms]

I think you may get better results with the 5x12 sac injectors than the ones that came in it. Would be interesting to see

[@NotSoGrandGarage]

We'll fi d out soon. They should be less prone to coking by design

Blue haze on idle is incorrectly vaporized fuel. Look at your injectors and a slight increase in opening pressure and an overhaul of the injectors will help. Also that needs slightly earlier injection timing as it takes slightly longer to build the higher pressure.

[@NotSoGrandGarage]

The idle haze started about a week in. It was clean prior. I actually think the timing at idle is a little too advanced causing spray slightly outside of the bowl which will also cause smoke. I'll clean these up for spares but I've got a nice set of injectors built by DieselTuff in Canada. I told him what I was doing and he pointed me towards the ones I got. I know the larger nozzle and higher pop will retard timing a bit so I'm leaving it over advanced until I see where it's at with the new sticks.

[@no-damn-alias]

@@NotSoGrandGarage well it may happen that it doesn't fully hit the bowl. Maybe you can confirm that with an endoscope into the cylinder or a batch of diesel. If that also smokes blue. Maybe something choked up your injectors.

Chris, would it help to have a tank of diesel (Or some blend) and have an automatic switch to run this other tank for a few seconds every (X) number of minutes? Could this keep things clean?

[@NotSoGrandGarage]

In my experience, a dual tank setup is ideal. If you run on clean diesel when cold... shut down on it... and short trips/extended idling on diesel... it greatly helps. I've got videos on my dual tank setups. The Tahoe has a second tank.. just not plumbed yet. That's coming but working out bugs and showing the process and experiments as I go.

[@jeffgreen977]

Does diesel keep things clean or just lengthen out the intervals between pulling out injectors etc.? I have an 85 f250 idi that I want to run on WMO and I want to do all I can to keep things clean... I bought a centrifuge from you (Thanks!) and hope to start running on oil soon.@@NotSoGrandGarage

[@NotSoGrandGarage]

@jeffgreen977 my 1990 350 has been on a 2 tank system for 5 years or so. I've never pulled the injectors... it hazes a little at idle sometimes but that's it. The idi doesn't typically care much. They are much more forgiving than direct injected engines
