6.6L GAS for 2010HD?

The main problem is that NONE of the OEM’s do PCV oil filtration setups on their engines.  If one preemptively installs PCV filtration separator “catch cans” on the DI motors, they can greatly reduce many of the issues.  I would never buy a used vehicle with a DI motor.  

 

From the new duramax features and specs sheet:

 

Venturi Jet Drain Oil Separator
• First of its type in the new Duramax 6.6L
• Designed to ensure oil control in sustained full-load operation
• Totally sealed system that collects misted oil entrained in the blow-by gas, allowing
for re-use in the engine
• Less sophisticated systems result in oil carryover into the cylinders during combustion

 

 

Maybe they will do one on the HD gasser as well.

Well, Ford has never done it with the Ecoboost and the problems with oil buildup in intercoolers and coking on intake valves is well known and extensive.  Valve coking has shown up in the newer Ecotec GM DI engines.  I have yet to see any U.S. OEM do a oil separation thing on their gasoline engines.  The Heavy diesel folks did it from day one when they started doing CCV on their diesels starting in 2007.  They didn't wait for the problem to manifest itself, they took preemptive action out of the gate because they knew full well what would happen by closing up the system and routing CC gasses back into the intake. 

 

So, any owner that has any one of the new DI motors needs to address this issue early on.  A catch can install is a must.

Should I be worried if my 159k mile 2015 5.3 has never had a catch can? I run it in M5 every single day to keep it in v8 mode. Just curious when anyone is experiencing issues caused by this. If I still have time and, it would really benefit me, I'd install a catch can. I run the truck pretty hard overall.

 

 Access to one e85 pump that is constantly "out of order" and it's usually more expensive than regular gas. I've used it twice in this truck. I wish I could run it more, especially for any savings!

No one can tell you  or anyone else if you should be worried or not.  Each person has to decide for themselves.  Get a bore scope and pull the throttle body and take a peek at the intake valves.  I will be willing to bet that it will not be a pretty sight.   I take the meaning of "preventive maintenance" seriously.  And no.. an oil change is not preventative maintenance.  It is a service.  So in the spirit of "preventative maintenance", I use PCV oil separation units on all my vehicles.  

 

One thing for certain, I will never buy a used vehicle with a DI motor in it unless I know it has had a PCV oil separation unit on it from the beginning.   And given what I have read over at the F150 forums, many folks feel the same way over there.

 

One can find a lot of examples of DI intake valve deposits just with a simple search on the net.

would a catch can do any good on a carbureted vehicle?  i have a couple that i would like to see last.

I would think a periodic spraying or fogging threw the intake with a product like BG,sea foam or equivalent would solve the problem.

Possibly.  But given the cost to do something like a BG intake job periodically, a PCV oil filtration setup would be no more expensive in the long run, and possibly less expensive.  Keeping the build up from occurring is far better than letting it happen and having to clean it up later.  Pre-emptive maintenance is always better than reactive.

True, may satisfy people worried about warranty knowing there’s something they can do as preventative maintenance. Rather than installing a catch can.

Of course, those who just trade off every few years, it really doesn't mean anything.  Given the quality fo many vehicles today, that seems to be the preferred approach.  Just dump the problems onto the next owner.

I guess you miss understood. Some people don’t want to install a can, they worry about warranty denial. I’ve used those products for years. I have a non GM DI with 100K miles and use seafoam every 10K miles, a very easy do it yourself project. I don’t consider it a after problem fix, I call it preventive maintenance. Will see she plans to keep it another 10 years.

I suppose.  I never worried about the warranty side of it.  I can easily remove the catch can from my 2015 2500 within a few minutes and have it back to stock, using only a screwdriver.   If one is worried about using a catch can and warranty, just remove it before going into dealer and hook it back up when the vehicle comes out.  I rarely ever see a dealer after I buy a vehicle.  But the ones near me, the techs are pretty savvy about the catch can thing and they never seem to have a issue if someone installs one on their ride.

 

That should overcome any enlarge paranoia gland issues by anyone. 

 

Have had one on my 2006 Cadillac CTS 3.6 for all but the first month we owned it.  Had one on a 2013 1500, but I got rid of that pickup because I was inventing new swear words about it and got a 2015 2500.  The can went from the 1500 onto the 2500 the first day I got it home from the dealer.  Granted, neither of these vehicle have DI motors, but the problem still exists.   All it takes is seeing what these cans separate out of the PCV stream will convince just about any die hard skeptic.

Strange... I was thinking about Sea Foaming my truck again. I was like "should I?" Then this truck passed and got in front of me. Haha, nuff said!

Now we have to speculate whether that was in regards to sea foam or foam insulation.
