WARNING- Oil catch cans & Diesel Engines

Hi SantaAus,
I'm no legal beagal but it apears to me that you would have this person by the preverbials,.....if my truck blew up after installing such a device..and could be proven by expert witness...well..I would give them the chance to fix and reimburse lost moneies...OR...I would take it further!...but thats just me we all handle things differantly...or do we?In my opion we need to know about this sort of thing so no one else gets caught!.Sorry to hear about your setback,for the want of a better word.

you dont actually have them by the short a curlies, nowhere on thier add does it say its for a diesel! when i had my wrx, they were perfect for that. the seller probably assumes that the buyer has done some investigation as to wheather or not it is suitable for thier vehicle. i know i wouldnt put ANYTHING on our pride and joy without propper research. it is like saying that even though a 100% atmosphere blow-off valve is illegal to use on the street, you fit one and the cops book you, that auto bahn etc... is at fault for selling it. you can buy a bong, its up to you what you do with it. lets not become america, and sue for things that are our own fault, just because we can!!!!
just my two cents worth!!

I don't know why you would need an oil catch can for a modern road car. In circuit racing they are required so ya don't dump a slick on the track with overflow/surge. The piping used is 25mm+ diameter.

In the old Z900 Kwaka's we'd slot a beer can in front of the back wheel with a pipe running from the breather. Stops it oiling the tyre when wheelstanding at 9,000RPM. Doh!

I do agree with the fact that some research needs to go into putting aftermarket products on cars/4X4. But the thing is that there was on part alot of internet time spent researching the reasons behin dand the resons for putting a oil catch can on my 4by.

Plus, my question to the seller--------
"Will this oil catch can work on all cars? I have a Turbo Diesel 4x4. I have already purchased this item off of you."

And thier reply-----------
yes, its for any car, NA/turbo and etc

I do give the seller his dues, the product is of good quality except for the 1/4" aquirum tubing supplied with the oil catch can. This product would be acceptable for most petrol cars, due to the lower compression that they have.
But for a diesel, which he states it is ok for, it WILL NOT DO THE JOB.

As far as I knew an oil catch can would fit any vehicle. And i could not find any information that would contradict this.

Personally, I think placing the blame on the catch can is bulltish. I'm more inclined to think it's more likely a seal failure on the turbo which can happen at any time and does quite often.
Blow by shouldn't be any more a problem on a diesel than a petrol. As for it pressurising the "oil lines", this isn't going to happen as the oil is pressurised by the oil pump far more than any possible "blow by" will produce. The statement about it dumping huge amounts of oil in the inlet, perhaps it was there previously before fitting the catch can. Your not going to pressurise the turbo with blow by to anywhere near what the turbo produces itself, don't forget the turbo is a pump and in your case probably boosts to about 15psi already.
I've built lots of catch cans myself and although the plumbing on your example is too small in my opinion I don't think its the cause of your problems. I prefer larger plumbing to and from the catch can and this is principally to slow down air speed. A slower air speed is better to allow the oil mist to condense and drop out of the air stream.
These cheap catch cans do very little, the ones I build are plumbed with at least 1/2" internal tubing, the cans are baffled to divert air then go through another baffle then finally a stainless steel scourer to absolutely minimise the amount of oil going through back to the inlet side of the turbo.
I've fitted a few to turbo 1HZ and 1HDT toyota motors as their oil screening in the rocker cover is particularly poor with excessive oil being dumped into the turbo inlet even from new.
