I have a similar issue and want to check the PCV valve. I see the part on the passenger side that has the coolant line attached but isn't there part of the PCV on the drivers side?

There is a hose that goes from valve cover to air intake tube. Both ends need to be connected securely.

Glad to see this thread. I run full synthetic in my V-10 and I hope I'm not doing a dis-service to my engine by doing so. My hope was to help with cold start ups, and coating the internal parts. I'm a little new to the motor so I do not have experience on my side.

I totaled my Escalade a month in a half ago and decided to give this beast a try. So I'm more familiar with GM motor than I am ones. In my Escalade I ran full synthetic. I would put Lucas in every other change. It helped me so much with giving the engine a buffer especially when I got the Trans rebuilt and it caused the radiator to fail, which brought about overheating. With the age of the engine I would like to think it was the buffer of the synthetic and the lucas that kept my internal engine parts in good condition. So of course I would like to take that same philosophy to my 2002 ford motor. Is this a healthy thought process toward this 6.8L engine?

Engines is engines. Can not imagine any harm coming from using a fully syn oil ?? I've had similar overheating EXperiences & attribute the good outcome to Syn oil & Lucas. I have no lab reports or shear test to produce BUT I can say this: If you have ever seen the little gear display used to show the webbing effect of the Lucas added to oil you would know the gears sit in a little pool of oil that carries up the gears as you turn the handle. 20 years ago I owned one of those displays. Just for grins I turned it upside down so that no oil was available for the gears to pick up. Totally forgot that I did. 2 to 3 years later I was moving some junk around & found the display still sitting where & how I had placed it. I begin to turn the crank with NO OIL AVAILABLE to the gears. To my amazement the oil with lucas webbed up & looked just like it did WHEN the gears were in the oil bath. That is how I'm sure it prevents dry starts & have used it in everything since.

UNI: You should put Stan on a healthy diet of 1qt per change & see how he likes it.

Well I have only had it for about 3 weeks now, so I'm really not at liberty to say. When I got it I did a full synthetic change. I commute to work about 50 miles each way so it will basically highway miles on the truck.

I have been talking to different people trying to get an understanding as to whether lucas and synthetic is a good thing for this motor or not. I try and take really good care of my vehicles.

Well, I'm not a big engine guy and I have always heard of some differences here and there. I thought that running premium gas would be best for the V10 as my 6.0 engine for Cadillac liked the premium better, but reading throught he forums I find that 87 is good and 89 if towing. So I'm learning the do's and dont's from you guys.

Synthetic definitely won't hurt it. As for gas make sure you have a good fuel filter and use whatever grade of gas keeps it from pinging under load or while towing. It is normal to ping some going up a grade and/or under heavy throttle.

Also check this out: Top Tier Gasoline

Better quality gas makes a difference. Techron is a good additive to use.

I second the techron. Regular use over a long period of time keeps things cleaner. I buy it by the case online and apply in fuel tank every oil change. I used to sell the Lucas when I worked at a parts store. I used it in my air cooled Corvair and it really did cut down on the smoke show that car was known for when it got hot out. However that was an engine I wouldn't have cried about if it died. I won't be putting that sludge in my Excursion until the oil consumption gets really bad. It does nothing but dilute your oil and make it thicker and your wallet thinner. You can get that from thicker oil and be better off.

Poking around on the site I found this very interesting . It was posted by FORD.
"Engineer Response
The 6.2L engine switched from 5W-20 to 5W-30 oil for the 2016MY to improve high mileage durability in the heavy duty pickup application. Use of 5W-30 oil in past model 6.2L Super Duty trucks is fine and should not negatively impact vehicle function however, the warranty would be affected. If we provide a recommended oil we have tested it to meet all climates and conditions for our engine. If the customer decides to deviate from our Owner Guide they will void their warranty. "

ONLY need to use the 89 towing if you have a tuner & have it set to 89.

That's like my 2011 F150, if you do ANYTHING to modify that truck its voids the warranty. You can't change the exhaust, put a tune on it, put a "performance air filter" on it, no nothing, nada.

This is a LONG list of possibilities when it comes to oil consumption:

I guess a few other things to try would be: put in a K&N style filter to reduce vacuum, put the stock tune back on the truck....
