Oil residue in intake pipes

[INASNT]

Any oil in the intake will always commence prior to the turbo (and quite often be visible on the turbo inlet) because the crankcase breather ventilates into the intake tract after the air filter, after the airflow sensor, but prior to the turbo. The crankcase gasses (which contain oil vapours) are dumped into the intake tract on the low pressure side of the turbo - so the gasses are vented into what is effectively a negative pressure area

This is what my reply to tigger was going to be. Without a catch can there will alway be oil at the turbo inlet so it can be combusted, oil at the turbo out is just going to end up in the exhaust.

Catch-can on my skyline caught a crap load of blow-by.

I find with VW they seem to all breathe quiet heavily, I assume the oil control rings are somewhat gapped quite wide.

My freshly built RB25 motor with top/bottom rings gapped 0.005" doesn't have much blow by at all (gapped it a big large on purpose, planning to squeeze in over 2 bar of boost)


A bit off topic, but here's a progress shot of my sietbok LOL

Normal...
Get a cheap oil catch can and some run some heater hose from intake and PCV for a DIY option or get a Racingline kit for near on $1000...

I got the burger motorsport and it's just a $20 AliExpress can (bit disappointed when I searched it after) so don't bother with brand names unless you go with racing line tbh.

Do this is what I bought off AliExpress. Going to build my own setup. May add the Afrika plate to the setup. Else just going to connect the Oem pcv outlet pipe to these pipes. Mount can on front right side. And see how it works. Sum total so far. US$55.

Loads of options on AliExpress. Get that this was the best for the prices. Got black obviously.

Got the nylon as braided hose and -10AN fittings to replace the cheap garden hose piping.

I had worst experience with items from AliExpress... so will always avoid them. I don’t trust their Quality (China made (mostly things are) there is no quality control.

True. But if you look for the right stuff you get some excellent quality.

I purchased the below and it came branded with one of the top brands racingline/APR/forge etc.

branding simply means their r&d is up to date.........r&d being receive & duplicate.

Yes. It was racing line and fantastic quality. Well built and well finished off. I’ve heard a few people mention that burger tuning intercoolers are from the east. As is their oil catch can. So even the good guys are rebranding Chinese products.

I have s majesty cooler and a down pie on order. Let’s see that quality.

ARB had an issue with warranty claims on some failing diff lock centres. They couldn’t understand the issue - billet machined components were fracturing which shouldn’t. Until they did some metallurgical tests... the machining was really close, the box and the instructions were basically perfect reproductions. Shame the core materials were cr@p.

Anyway, I won’t reward knock-offs with my dollar - it only damages the companies which spend the money on genuine research and development.

I’m pretty sure companies like APR Racingline etc aren’t selling their products on aliexpress. Why don’t you email them a link to the product and ask them if the product is genuine?

Is it necessary to fit a catch can to a standard 162TSI?
I will be removing my Elite can from my Commodore VFII Redline before sale.
If these 162’s get a bit of blow by, I could fit the Elite.
