...grease inside intake?
 

I was approaching my clean/recharge interval on my K&N filter, so naturally I pull the airbox. After I get the airbox out i noticed what looked like something pooled in the ribbing of the intake piping near the throttle body. I figured since the shop that had my car overfilled the oil ridiculously, that was what it was. However, when I ran my finger through it, I got what looked like clear grease on my hand...Anyone have any idea what this might be?

Notice the pooling in the ribbing.

Hard to tell exactly because its clear, but on my middle finger you can see the clear coating, then to the right of my fingertip you can see where i intentionally rubbed it together a bit, that should give an idea of its consistency and texture. Any ideas just what that stuff is gathering in my intake piping?

Any chance it's off of the K&N filter? (the recharger fluid) .

It's puking oil, time for a compression check ...

Oil that looks like clear grease?
(I'm not trying to sound like a wise ass, I'm actually asking if that's how it looks and why)
The shop I picked it up from did have the oil ridiculously overfilled though until I noticed it and drained it about a few days ago.

Team, you're the first person I've noticed talking about puking oil and compression. It makes sense, but is there a reason you don't think a little in the intake could be from filling the oil?

Unless something happens that vastly changes the oil, I don't think its oil. Again, i'm not 100% sure, but there is zero oil in my air intake box, or on the filter, or in the housing for the maf.


There's just that white grease looking stuff collected in the ribbing on the intake pipe. I swabbed some off with a screwdriver, looks just like grease, feels like it too. I know in the picture the pooling looks like regular motor oil, its not, its that grease looking stuff.

The 2006 did have Some revisions to the hose routing that was supposed to prevent the "oil in the intake" issue, or am I thinking of something else?

I can't tell what it is. Just that when the engine pukes oil that's where it goes.

Just clean and check later to see if it comes back.

Otherwise I've been saying that "an engine that routinely pukes oil is a general indicator that it's going bad" for several years now.

The TSB being referred to had nothing to do with this issue

I was unable to intentionally make oil go in the tube while pouring it into the filler spout, the idea was shot down many years ago, plus it won't come back again like when the engine is puking.

Cleaned and put the intake piping back on today, no oil, but here is a closeup of the clear 'grease' that came out of the ribbing on the intake piping.

uggghhh, maybe an assembly lube of some sort. Was that in all the ripples, or just the first one?

Yep. If you look at the photo I took of the inside of the intake accordion pipe you can see it in the center of each 'ripple' I have no idea what it could be.

My 2004 has the same thing. Cleaned it out, but it was a thick grease like yours (not runny oil). Not sure what it's from though.:dunno:

Either oil from the KN filter or oil from the engine.

My bet it's from the engine because you stated they massively over filled the oil.

^^Oh gawd .....


.

Something I'm missing? lol

it's been discussed ad nauseum, i give up and don't care any more ...

Either you sprayed too much oil on the washable filter or the oil level was too high and sucked into the intake.

^^Oh gawd II .....

rofl

That looks more like lube grease than oil...

I think the "Clean it, and check again later..." suggestion is probably your best bet.

yeah, thats what I did. My only guess as to why it would be there is maybe there were tiny holes in the ribbing creating a vacuum leak? I havent noticed anything yet but I'll look more into it.

It does take a second or two to return to idle after free revving. hovers at about 1.1k, then falls, to 1, then to normal. approximately of course.

Sprayed some cleaner on some of the hoses today actually and didn't notice any change in RPM's, maybe im just not looking hard enough.

:suspect:

I mean... it's definitely oil from overfilling.... ya...

:suspect:

it was also established as not being oil so the next person to suggest that it is wins the :dunce: of the year award

Established by whom? The OP was not sure what it is, and no one has offered any credible alternatives to oil. I had the exact same thing when my oil was overfilled. Also accompanied by a nice oil stain on the air filter, and oil that had seeped into the air box. This is clean oil, don't expect it to look like the stuff you drain from the oil pan.

Lol. This is a good one.
