Ok, more info… The engine was manufactured Sep. 98’ This truck is known as an early 99’. The engine has 170,800mi, most of which was on Mobil 1. I installed the by-pass just prior to the “go-live” WVO conversion. I’ve been running veggie for around 10k miles. Uneventful operation so to speak. The truck runs almost as good as on #2, all the way down to the amount of smoke.
Some observed info on the system. I have temp sensors: in veggie tank, in Vormax Filter head, in manifold atop engine 4” from fuel ports on heads. Knowing these sensors work off change of resistance, I’m not sure how well these units are grounded and have been suspect of their readings. That said, here is how I’ve operated. Start on #2, travel ~5-7 miles (while observing sensor in the Vormax Filter looking for > 125F), switch to veggie, monitor sensor atop engine to ensure temp rises. At 10-15 miles I’ll be on my way to 150F. Under most circumstances I can maintain 150F or more barring cold rain, or just blowing cold. I still have not insulated any of the system. Although today when ambient temps tipped the mid 80’s, I was reading close to 180F have not seen either of those temps here till today. Finally I shutdown on #2 (travel 1 mile/Idle 1-2 minutes) That’s how I’ve arrived here.
Now if you’ve read the report and wondered about the comments, I have no idea why the inference was made about changing from veggie oil to oil. I spoke to Ken on the other poor report (next to last report) and thoroughly explained what was going on. I believe the suggestion is to switch back to #2.
By-pass filter changed along with full flow and 15 quarts oil at 165,700mi. This sample was drawn just prior to the recent full flow and 15 quarts oil (170,000) change.
Brian, you probably read before I got a chance to post my report to webshots. Take a look and you'll see how WELL my engine was wearing prior to conversion
