I think that using Veggie Oil would guarantee that they get Plugged.
Monark and Bosio Nozzles do not have the drilled passages.
Could it be the Valve Stem Seals are allowing Oil to get by the Valve Stems and into the Engine?

I do not know what year they changed from Pneumatic to Mechanical Governors on the Fuel Injection Pumps.
If you have a Pneumatic Governor a bad Diaphragm or Vacuum leak in the Housing can cause some issues. There has been some within the last week to 2 months threads on that.
The Marvel Mystery Oil will work only if the Rings are sticking due to Carbon Build up. People say using Synthetic Oil; after driving 200-300 miles will also free up sticking Rings. |
Which picture are you talking about? What is the hole for? Seems odd that some manufacturers would do it and other wouldn't. I know veg oil is hard on injectors, the original injectors has nearly 300k miles and about 40k of those were veg oil miles before they started nailing. The new ones started nailing after about 15k miles, I don't think I can blame all the nailing on veg oil.
Seems like valve stems seals should be done just cause the engine has 320k miles and they are cheap, and it sounds pretty easy to swap them.
I use the partially synthetic Delo oil, and it's been a few thousand miles since I removed the system, seems like the rings shouldn't be stuck but when I pull and check the injectors I'll drop some MMO in just for good measure.
