Too much oil in the intake?

I was installing an Intake Manifold Spacer (IMS) from XTP yesterday afternoon and noticed what appeared to me to be excessive oil in the intake. Most of the motors i've ever been in were old and in need of work, and therefore disgusting anyway. I got nervous seeing that much oil in my new'ish truck. Is this normal oiling, or should i be worried?

 

I see an oil catch can in your future?

 

That's caused the the recirculation of heated air from the crankcase back into the intake for emissions reason's. Best thing to do is install an oil catch can to stop that.

 

Yup go to Amazon get the, add w1 oil catch can and than search TW for oil catch can the OP is detective dan and I think on the 3rd page is my install of my can. Detective dan did a good install write up as well good luck OP

 

Does anyone know if the oil catch can system will affect the warranty? It is modifying the emissions system after all... I know it SHOULDN'T, but we all know how things are these days...

 

Thanks for the head's up on the catch can. I'll definately do that.

Next question... What can be done about the existing oil in there without removing everything and doing a manual cleaning? Any chemicals or sprays or additives to clean up that oil? I've used seafoam for extremely dirty motors before. Would that get it done?

 

^^^^^^ This

 

Actually no, you're still ingesting and burning the oil vapor, just not the raw oil.

Can somebody please explain this a bit more?
Is this mod recommended in all scenarios, or only under certain circumstances?
Will it improve/extend engine-health?

 

Engines build up internal pressures and it needs to be relieved. This is done through the PCV valve. Emissions laws don't allow for those gases to be released into the atmosphere, so they run a tube from the valve back to the intake so it's recirculated. With the pressurized gases though comes oil from the engine. The oil gets sprayed back into the intake system and gets everything gunked up.

So yes, it's a good thing to do in any case.


The catch can has 2 tubes that come in to it. An in and an out. The gases and oil come in to the can, but the oil drops to the bottom of the can instead of flowing to the intake. The gases exit through the 2nd tube and recirculate.

 

Chris is correct, to expound a bit further, the excessive oil is not good on the combustion chamber and components from accelerated carbon build up.

 

And with more engines going to direct injection, the problem is probably going to get worse / need more attention in the future.

With port injection you at least have the fuel to wash the backside of the intake valve. Direct injection is just that, direct into the cylinder, and that oil / vapor will get baked onto the valve.

 

Thanks for the replies fellas. Ordered one today from Newegg.
Truck only has 110 miles on it right now so I'm going to do this mod early!

 

Hasn't created a problem for Diesel engines.

 

I would think that a manifold spacer would have more of a chance of effecting your warranty than a catch can. I'm planning a catch can at some point this summer. And hey it's a Toyota! Why would you need a warranty

 

I had an 07 VW GTI that had DI. They were notorious for the carbon build up on the intake valves. Mine had 60,000 miles before it started to cause problems with random misfires and starting hiccups. Only way to clean them (properly) was with a dentist's pick and carb cleaner through the ports.

 

He's absolutely right! Direct injection is a great technology for about the first 20-30k. Problem is the huge carbon deposit build up on the valves and on the pistons. Largely due to no injector above the valve to help wash the carbon build up or allow for a decarb service. And with the extended oil change intervals the oil sludge build up is huge and crucial effecting the cam actuator valve.

The carbon falls into the cylinders and or builds up on the pistins and or rings and causes scoring (some auto manufacturers are calling the "zebra-ing" and calling it normal. ) thus allowing oil to blow by also adding to the carbon deposits. Some of these deposits can find their way all the way to the cat and cause pitting or burn their way through the cat. Cats are expensive. Do a compression check and see which cylinder is low. Or stick a borescope in and take a look for yourself. While you are in there look at the valves, top of the pistons and then find the injector. Notice how the build up on the piston is and this build up directly effects the way the fuel is swirled in the combustion chamber. look how dirty the deposits are on and around the injector tip.

The key is to do more frequent oil changes!! Keep the oil clean thus preventing sludge and to run a good oil cleaner. Research BG 109 compression performance restoration. Also a anti oxidation oil additive as well. Antioxident is the key! BG MOA. Try

$25 BG 44k Fuel System Cleaner Power Enhancer 11oz.

BG 44k in the tank for the fuel and carbon clean up. The key is preventative maintenance!!!! down the road you will be doing valve jobs and piston rings. not cheap!!

I work with Dealerships as well as independent shops and I can not tell you the amount of problems this new technology is having early on in cars.

 

That might be true for diesel but not with the gas direct injection!
