  • 6.0 Info

    Hi All - just thought I'd post some things I've found with my 6.0.

    I installed my Vegistroke last summer but soon I found it would start cutting out on me - even after the truck was up to temp for a considerable amount of time. The light on my switch kept turning on, then off. I wasn't doing a lot of driving so I really didn't worry about it until it started getting colder. Then, this winter I ran 200 miles on diesel, got out and checked the coolant lines @ the veggie tank - ice cold. Other probs were intermittent heat in the cab and the truck had some slight puking issues out the degas bottle. Even though I didn't lose much coolant, and the degas bottle read that it was at the proper level, I wasn't getting heat.

    Here was the fix: As most of you know, the 6.0's have EGR issues. I deleted mine but still had the same problems. We then pulled it apart to do head gaskets and studs. While we were in there we replaced the oil cooler too. Also replaced the T-stat and checked the water pump which was fine. I've seen people post about going from the 03 pump to the larger 04 but I now realize this is not needed - the 03 pump works just fine.

    A side note: To those of you doing new headgaskets/studs, I learned that when you are getting it done under warranty, Ford will not resurface the heads. You may think they are, but Ford won't pay to have it done. My truck was out of warranty but in speaking to a 3rd generation shop owner who does a lot of heads for Ford, he said he's instructed to NOT TOUCH the surface of the heads, unless the customer requests and pays for it. In his own words, those heads are so crudded up leaving a bunch of hills and valleys that even with studs, he says he'll have your heads back in his hands months down the road because of blown head gaskets once again. I'd spend the money to resurface them and ask your dealer to make sure it gets done.

    Anyway, my heat probs are no more. I'm certain my head gaskets were the issue. Somehow, although they weren't really bad, they were allowing enough to escape, causing a permanent air bubble in the system which wasn't allowing hot coolant to the air box, or the veggie system.

    Now, the truck heats up incredibly well. It warmed up to 14 degrees here the other day. I started the truck, let it idle for just under 10 minutes and when I got in, the veggie system was on!! Not to mention the fact that I currently have LARD in my tank - not oil. I speak from experience - this Vegistroke system, combined with a PROPERLY running truck can run even LARD with no issues in MN cold. As a matter of fact, it was -2 degrees, I started up a cold truck, let it idle for maybe 3 minutes and drove on the back streets for 2 miles and bam - with only LARD in the tank, the system turned on. Unbelievable.

    My point is that if you are having heat issues with your veggie tank, it could be a number things but you should consider some of the things I mentioned. Although I didn't try to take it apart, I have a suspicion that my oil cooler was all clogged up. I now have a coolant filter installed too.

    Hope that helps some of you! Happy Vegistroking!!

    Good to hear, Thanks for sharing that with us. It's no secret that the 03-04 trucks were full of issues, but even coolant flow too? That is really good to know. I imagine the Clay Henry idea of installing a coolant circulation pump would be a cheaper way of helping that issue, than the correct EXPENSIVE fix that you did. So now with surfaced heads and studs you going to go nuts on power mods?:chuckles:

      Sorry, I've been out to lunch...

      I've got a Banks 6-gun - that's probably what caused my headbolt stretching probs in the 1st place. With the $ I'm now saving on diesel, I'm sure I'll be adding more stuff down the road.

      This wasn't a cheap fix, that's for sure - but it was necessary. And, for those of you back yard guys (like me), you don't have to pull the cab to do studs. TheDieselKid (from other forums) came out to help me do mine. He taught me that you only need a 5 lb sledge to put a little dent in the firewall. There's other advantages to removing the cab (obviously) but I'd swap a couple taps with a hammer for removing the cab any day. Especially if you don't have a lift.

      I read one of Clay's posts a while back about installing a circulation pump. He may have different issues than I did but I can tell you that on my truck, with a stock water pump '03, the coolant at the veggie tank gets hot FAST - even with our below normal MN winter temps. If your truck is running right, you shouldn't have any probs with that.

        hmmm....very interesting. My heater has always worked great but for some reason coolant to the tank and back was circulating way to slow untill i added the pump and BAM, working like a charm.

          Clay, your in TX, right? I never had issues with my heater until it got COLD outside and by cold I mean under 20 degrees. BUT - I definitely had issues with getting HOT coolant back to the veggie tank - even when it was considerably warmer out. It did limp along in the summer heat - enough so that I really couldn't tell I was having a problem until it turned cold.

          Has your truck puked at all out the degas bottle?

            I'm convinced that the issues with my heads and everything else caused an air bubble in the system that would simply never go away, especially if the cause of the problem is never fixed. I can definitely see where a pump to aid in circulation would alleviate that problem but it might mask the real problem and cause you more damage down the road. Hopefully you don't have bad head gaskets or in my case, warped heads too. They're awfully expensive to replace as opposed to getting them milled. Food for thought.

              I'm in OK and we do get a little cold weather here but nothing like MN. We see our fare share of 20-30* nights and a few in the teens.
              I do not have a coolant heat issue when its above like 50* so i turn the coolant pump off in those temps. Never puked or lost any coolant so i don't think i have head issues (knock on wood) but i continually watch for it as i do hammer on the GO peddle hard on a regular basis. Plans for a lift to go in my shop are also in the works so when i need to i can pull the cab off either to rebuild a motor, do head work or whatever. I hate trying to work under the hood on that thing. Cab off isn't really hard at all...an experience mech can have it in the air in under an hour so i figure i can do it in a couple hours probably.
              Thanks for this post!

                Hopefully you never have head issues, though I have to wonder why you would need something to help move your coolant - unless you had head issues - or something - causing an air pocket. Something's telling me there's something goin' on. Maybe it's just a water pump issue?? I checked mine and it was in great shape so I left it alone. Plus it's another big expense upgrading to the larger '04 which is what I probably would have done had it been bad. Now I've got proof it's not necessary if everything else is fixed.

                That's awesome that you'll have a lift. If you were closer you'd be my new best friend!! I hope you don't have to use it much!
