Fresh oil in the air-intake
« on: 14 October 2009, 14:09 »
Hey,

When i cleaned my throttle i found oil around the air intake under the casing at the top of this picture;



a friend thinks is the piston rings gone meaning oil is being pushed up the tube into the air housing

any ideas? sorry for the lack of proper pics

cheers

just the breather pipes. Hence why I'm making an oil catch can http://www.golfgtiforum.co.uk/index.php?topic=131909.0.

Just clean it with a toothbrush and carb cleaner and your all set.

so the fact mines got fresh oil sitting in it isn't a bad thing? i thought it was only for fumes rather than oil, although i guess it would collect over time

if i clean it out and week later it's oily again, what would this mean?

it is fumes that are supposed to go through the breather, but from the high pressures oil is forced out. As you said, it collects over time. If you clean it out, it will get oily again over X amount of time. I clean mine out once a month to keep the car running as smooth and trouble free as possible!  :smiley:

As long as the car aint using too much oil, air fuel leaks past the piston rings during compression especially as the engine wears and pressurises the crankcase, that pipe relieves the presure and recycles it through the engine and as Khare says unfortunately some oil gets forced up too.

piston rings do commonly go on them engines, but you would hear it knocking.
the oil coming from the breather is nothing to worry about. strictly speaking it shouldn't be there, but in practice it always is! unless there are other more serious symptoms do not worry!!

tappety noise will be the tappets. Drain 1 liter of oil from the car, then replace that liter with ATF (automatic transmission fluid). Run it like so for a week, then drain the oil and replace it with new fresh stuff, remember to do the filter too. This will clean out the tappets and the internals of the engine VERY well  :smiley: This should shut the tappets up and give smoother running  :cool:

If the top end is really noisey, then i would get the oil pressure checked.
By all means use a flushing agent, but do not drive the car with it in it.
