Question for 350c eng. techs

Well I have been running my 350c a lot this summer and this weekend I noticed the oil pressure was way lower than normal (just in the green by a little). I shut it down to see what was up and the oil was over full buy a mile and very thin. I pulled the fuel pump and the diaphragm was leaking fuel past it right into the base---NICE!!---Question is, what if anything would this have harmed??

I bought a 450 outside dozer a while back that had spun a sleeve on the crank after the fuel got into the oil. I bought it that way and the seller thought it had likely ran for quite a while before the damage occurred without the operator being aware of the problem.

The crank is beyond repair. (I have another Engine, a project for down the road )

Good thing you had an eye on that oil gauge.

mine did only run a short time with fuel in the oil ...so i was in luck unlike the one you got scotty.... if ran a long time it will wear out a lot of things ...Diesel is really not a good bearing lubricant

I figure when I put the pump on and service it, I will also take a sample of the oil and put it on a white paper to see if there are any fillings in it. just serviced it 20 hrs ago with Amsoil full syn. and a gold series filter.....who on here says there is "no such thing as a cheap crawler"....

If you did any damage, most likely it would already be knocking. I would fix the problem, change the oil, run it a while, and change again fairly quickly, and see what your pressure does now.

Well I put the new pump on, new filter and oil, also took a good look at the oil I removed with a high intensity light to see if there was any glimmer or flake in the oil and it was perfect...not so much as a spec. even went as far as to get a sample from the filter itself....all is well. oil pressure 80 psi hot at 2000rpm and 58-60 at idle. back to were it always was. as Lavoy said I a bought an extra oil filter and oil just for a good flush....thank goodness for Amsoil full synthetic.------buy the way Lavoy our isolator conversion (C to D) is working perfectly...thanks again.

Do these things not have the issue of syn slipping past seals like older cars do?

I watched for that exact thing with regards to oil consumption using synthetic as I have seen vehicles switch to syn. and use a ton of oil...switch back and consumption drops back to normal. so fare this has worked just fine with Amsoil 15-40 full syn. all the other oils I just use JD hyguard.
