New insight in IDI burning WMO - need high compression or turbo

[Black dawg]

opening up those holes from the heat shield would defeat the reason why they're there, to keep the ignition heat away from the injectors.

That os what I figured, and maybe the heat would help keep tje injectors clean. Injectors dont last a long time running on wmo.....

this is the injector, the tip is a small needle which rocks back and forth. Gets carboned / fouled up over time. just alot faster with wmo

Here's one from the net, after running it 100k miles +-

Mine looked the same after only 10k. The headshields are in the first post.

If those shields are easy to get and cheap, I would open that hole way up and see what happens.

The 6.2_6.5 injectors looked like that shield was built into the injector body. Looks to be the same size hole on the end, that would always build up that same looking crud.

What recepy of WMO youre burning there?
I had resonable succes with a oil/ gasoline mix (can't remember the percentage anymore,) but just enough gasoline to make the viscosity right.
can't say that I had any negative effects on the injectors (that I noticed) , the only thing I remarked is that it's oil starten to thicken in a really mysterious way?!

I'll see if I can dremel them bigger, nice idea.
Got a summer mix running now, 75%wmo25% kerosene. Winter its more or less 50-50. I'll try with RUG next, the manual of the car says I can run up to 30% unleaded. Should thin stuff out nicely. Does it evaporate over time?

Has anyone tried the additives to increase cetane or clean the deposits out?

Power Service sells both a cleaner AND cetane booster. Here; https://powerservice.com/?utm_sourc...148450&rl_track_landing_pages=1&rl_retarget=1

There is nothing that will touch those deposits.
Tried many different things, including water injection starting with clean injectors would still end up this way.
Have not seen this with any other style of injector.

I am familiar with the additives. I am not familiar with the deposits etc. I use additives in my IDI as the low sulfur fuel sucks. I just wanted to know what these experienced people had tried/used.
