gasoline in catch can

[jt15833]

i added a catch can to my engine a while back and during that time it never caught much, a little oil every couple hundred miles. Then I stopped driving the car for a couple months while I was away, although I would start it up and run it for a little every few weeks. Now that I'm driving it steady again, it has a pretty good amount caught in it just after a day of driving, its very liquidy and smells like gasoline. what could cause this?

Change your oil and filter, drain your catch. Start with that and keep an eye on the catch cans contents afterwards.

Do you have vaccum pulling on that can, and im assuming you have both intake and exhaust breathers running to it?

sounds like you are running too rich! how does she run? does it bog any under load?

i got 2 lines t'd and check valved going to it, one from the intake tube and one from the valve cover. the catch can lines are set up to be under vacuum during boost and vacuum. My only fuel system mod is a walbro 190lph pump so running rich could be a factor, but how would it get into the catch can system? my only thought (hopefully wrong) would be slipping past piston rings into crankcase. I'll drain the oil and check that for fuel. I'm not sure what would've changed from not driving it because I made no changes and at first it was doing really good catch can wise, but a few months later its getting this fuel. runs great too, no signs of richness.

When your car runs filthy rich, it causes this condition. The gasoline rinses down your cylinder walls and get into the oil in your sump, so now when your engine spits-up oil, it's not just oil anymore hence the reason the stuff in your catch can smells like fuel.

I don't know what the problem is, but I want to see if it will catch on fire, does that help?

[r34 gtr]

wow, that went downhill fast. cant think of relevant responses and still keep up with me? haha, i joke, i joke, no one can whore it up at your speed sir.

[float_6969]

High speed DSL FTMFW!!!

[r34 gtr]

yeah, mine usually hauls but my neighbor's kid is whoring up my bandwidth with limewire.... thanks emo skater punk. at least i can feel good about myself because he wears women's jeans and i dont (too expensive).

[float_6969]

emo skater? sounds like your bf....

[r34 gtr]

you mean ex-bf.

[float_6969]

next bf?

[ca18det240hatch]

ok ok break it up you two, theres a new whore in town

[r34 gtr]

you have a lot to learn young grasshopper.

[ca18det240hatch]

so....hope i dont see gas in my catch can....*crossed fingers*

[r34 gtr]

you wont see gas, the oil just smells like gas. can be from totally worn out rings and/or running very, very rich.

[jt15833]

im glad my thread has turned into a street corner. thanks for the responses tho i dunno what could have made me run rich like that. ill do a compression test to narrow it down if its rings or not

[r34 gtr]

i would bet the injectors are a little gunked up from sitting so long. if you go rag on it you might cure a lot.

[float_6969]

If you're mid grade is like it is here in KS, it should be 10% ethanol. If it is, fill up with that, don't get into boost too much, and run a tank full. The ethanol is great for cleaning out the fuel system.

lol

[Masterdebater]

u guys are filthy whores!!whores i tell ye!!!!maybe ur injectors are leaking fuel when its not running and dripping down into oil pan?BTW dam emo kids...aaaand there hick bfs.

[jt15833]

how bout the fuel system cleaner they have at auto parts stores? any good? any recomendations?

[ca18det240hatch]

mix some prestone in with a quarter tank of gas....may work.
