What is this gunk in my Oil Fill Neck?
1 Attachment(s)
I opened up my Oil cap to find this yellow gunk in the filler neck. It's like coolant is leaking into my Oil but the dipstick is perfectly clean of it. I use Castrol 10w30 synthetic. I cleaned it off and am going to see if it comes back. Is my cap loose and moisture is just seeping into the neck?
Thanks -Ghooble Attachment 493849 |
Looks like coolant condensation build up.

it's normal if you drive short distances.
have people ever heard of google? |

have people ever heard of google? Well as an IT worker I'd sure hope so. I didn't really know what to search for and figured if I made a thread then others would be able to find this. I appreciate the responses... -Ghooble |
Did you remove your pcv valve?

commonly known as "lung mustard".
when the engine heats up/cools down. the oil tends to froth and then Condensates..it Rises to the cap and sits there so you can open your cap and Say "WTF is this crap?" |
The moisture on the inside of your oil tube is condensation.

no mustard here .. and this engine is both LPG and turbo.. and as such it should have a worse issue than most its all in the vent line hose sizes and the positions vapours run out of the top of the cap to filtered air pipe pre-turbo ( or air cleaner in NA car ) a second,, same sized nipple and hose halfway up the filler pipe draws filtered air from a rocker cover filter tucked in corner of bay ( via a one way valve ) and thus the system is in constant draw though ventilation while the engine runs using the high point allows a more total scavenge of vapours and avoids getting too much liquid condensate carry over .. i run without a catch can.. and for turbo am using 9.5mm EFI fuel line as vent hose only hassle is you need to loosen the hose clamp to take off the filler cap |
