Re: Low oil pressure after Lucas additive?

Thanks Aaron. Used "Lucas Oil Heavy Duty Oil Stabilizer". Since I had just changed oil, I drained 1 quart and then added 1 quart additive. At 2k rpm showing about 25psi cold and about 15 at operating temp. I'm thinking I might drain it all and go straight rotella 15w40. Just want to ensure...

Low oil pressure after Lucas additive?

YM2000 Sure don't intend to falsely accuse Lucas but right after adding a quart of oil treatment with oil change (rotella 15w40) my oil light which has always flickered at idle when up to operating temp, now comes on at higher rpms. I have an oil gauge too which confirms low pressure. I know I need ...

Am I running too cool?

YM2000
Even under a moderate load I can't get engine temp over 130 degrees as measured with new temp gauge. Is that ok? New radiator, water pump, hoses, etc. I hope it's ok as without a thermostat, there's no way to make it run hotter. Thanks

Re: Run away diesel

Yes. I do have some noticable blowby. I assume my oil pressure is low too at 16psi at 2000 rpm after warm up?

Re: Run away diesel

Update.....mechanic returned injector pump back to pump company. Got back yesterday and was told that he found a problem.....a "piece of metal" in the pump was causing it to go to full throttle position. Got it back on and throttle now controls rpms as normal. Hallelujah. Was also told tha...

Re: Run away diesel

More bizzare info...... My yanmar certified diesel mechanic is baffled too. He started engine and it is belching white/grey smoke and rpms running away tho he was able to manually control rpms with fuel rack. Exhaust was spatering black fuel (I guess) onto the ceiling 12 ft high. He could not find a...

Re: Run away diesel

Winston.... I did pull that plate yesterday and got a good look at governor and no apparent problem but really don't know what to look for?

Re: Run away diesel

Checked foot throttle linkage and it's ok. It's like the governor is sucking the rack to the extreme forward position. When engine is running I can't pull rack from forward position regardless of the throttle lever position. What's weird is I'm pretty sure the forward rack position is low rpm and ba...

Re: Run away diesel

I always start with wide open then back off when it starts but of course the throttle is not having any effect whatsoever now. Wonder if I should disconnect governor and manually move rack to see if it controls rpms. In my ignorance, I also suspect something is wrong with pump. I will talk to local ...

Re: Run away diesel

Checked all linkages and rack is freely moving. I started engine and it began reving up as before but I was able to regulate rpms with my hand over the intake. The rack is locked in the max forward position when engine is running. I could not move the rack at all while running. As I choked it down w...

Re: Run away diesel

Ym2000 Thanks Winston. You are a Godsend! I did get the spacer and keeper pin on without incident and I did ensure rack moved freely before installing but did not move it and throttle linkage after pump installation thru inspection plate....wish I would have but it all went back in place so smoothly...

Run away diesel

Starting new thread from "diluted engine oil". Changed oil and filter, installed rebuilt injector pump and connected governor linkage just like I found it. Bled fuel system and it was slow to start but when it finally did....rpms took off and throttle had no effect. Seemed like an hour, bu...

Re: Diluted Engine Oil

Thank you for the clear answers to these questions Aaron. Regarding the leak at filter.....It was not leaking at the bowl before disconnecting but when I tilted it after disconnecting it began leaking as I could see fuel puddling at large bowl nut. I don't see how it could leak there if the "O&...

Re: Diluted Engine Oil

Removed fuel pump today. Had to drive a scraper blade behind it to persuade it to come out. Wow what fine clearances! The pump seemed to be wet on underside with the definite smell of diesel. Questions: *That should be a sign I'm on the right track, correct? *I still suspect air is entering into fue...

Re: Diluted Engine Oil

I drained engine oil and do not smell any diesel fuel but really don't know if it would be enough 2 impart an odor. This is my strategy. I let it drain 4 a couple hours until no more was running out then replaced the drain plug and turned the fuel petcock on. In a couple of days I will catch what ru...
