Catch Can Leaking Oil

[KrazyTurk]

iv just realised the left front of my car is drenched in engine oil & the leaks coming from my catch can which also feels very heavy

so iv bought a new one and going to get it replaced should i be worried?

[Ben C34]

Depends.

How quick did it full up with oil?

[Hadouken]

You don't have it draining back into the sump or head then this will always happen.

But yes, how long did it take to fill up? Sounds like excessive blowby or the catch can is hooked up wrong

[KrazyTurk]

i bought the car recently im asuming it was like that when i got it

i did a oil refill few weeks ago & checked now its still full though im pretty scared about the leak

can running high boost be a factor in this?

sounds pretty scary to me,I've had a catch can on for 7 years not a drop in it and 15 psi daily.

If I was you I would be very worried time to check every thing,good luck hope it's an easy fix.

[Ben C34]

High blowby causes high amounts of oil into a catch can.

It's a sign if a worn engine.

[Humbla]

sounds like previous owner might of flogged the crap out of it.

[Hadouken]

Or the catch can is plumbed wrong. Take picture. Show us

[Ben C34]

Can't be plumbed that wrong.....

As in a top up or did you do an oil change. Or did you just add 5L of oil without draining the old oil like some less than competent forum members have done in the past?

dont see how this would matter

iv got the can replaced now

should i do a leakdown or compression test to be sure?

[Ben C34]

Huh?

He asked if you drained oil before adding oil. That's a fair question seeing as in the past people have overfilled engines by many litres due to their lack of mechanical ability.

So to be clear. Where is the oil on the dipstick?

[Ben C34]

If I had an engine that filled the catch can I wouldn't bother with any tests. I would start planning a build or engine swap straight away.

[KrazyTurk]

yeah i know what he's asking but what would that have anything to do with the problem im having

[Josh080691]

Alot.... Haha if u dumped more oil into the engine the oil would obviously go to the catch can.

[KrazyTurk]

oh.. yeah well i can say i did overfill the oil

going to do an oil change tomorrow anyway with something thicker 20w-50

ill see how i go with that and the new catchcan

[Josh080691]

So u most likely just caused ur can to fill and it had no problem in the first place oh well lesson learnt

[Ben C34]

Well there you go.....

An overfill will cause oil to spew into the catch can. Hope that's the case.

[KrazyTurk]

ah i didnt notice any leaks before topping the oil up, hoping thats the case also

[Ben C34]

Based on that i recomend Before you do anything else on the car get some advice
