So what happens when you get blow by....

Remember all engines have a certain amount of blow by...

I can see it now... I fitted this thing and i blew my engine... It looks like a modified PCV Valve (crank case vent valve)...

Me no like playing with that....

Our targa BMW had a we little crank case vent problem on the last day of the targa... The air vent on the top of the catch can blocked up not allowing breathing.... Then she went boom....

So i now always have a free flowing catch can....

The valves will let the blow by pressure out...

So does a catch can... With a vent....

Not being rude but whats the point of this thing....

I mean it does not do anything a catch can cant do...

These valves give negative pressure (vacuum) in the case. An open catch can(assuming no vacuum pump) will leave atmospheric pressure in the case.

Vacuum in the sump is a good thing. It helps to keep the oil clean and the engine will make more power because the pistons do not have to displace and compress air on the way down.

You could always use these valves in conjunction with a catch can.

Yeah i did a bit of re-search today...

I missed the point... A bike does not have room for an oil catch can... So its the next best thing.....

Now i see.... But yeah it sorta answers the original question...

No i would not use one on the car as its not needed yes i would use one on a bike as its the alternative to an oil catch can in limited spaces (no spaces on a bike)...

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
