Possible solution to blow-by & EGR?

Jambo (hello) from Kenya!

I've been doing a fair amount of research into solutions for the EGR and blow by issues on my 2000 1kz-te with the electronic throttle body and SCV.

I had what I think is a great idea... I imagine it would also work on the older versions of this engine.


Blow-by can be fixed easily enough with a good catch can, however even with my mishimoto catch can I still get some oil vapour into the intake and lining the walls of the turbo, intercooler, throttle body etc.


Now one of the issues with an EGR delete is the lack of air being put into the intake manifold while the butterfly valve is closed.
One solution to this is to remove the butterfly valve and risking a runaway engine plus the rough shut down.

My idea, and what I plan to try, is to put the EGR valve back onto the intake manifold, removing the blanking plate I made.
Then I will route the blow-by from the PCV into the EGR valve. I'll probably still run it through the catch can seeing as it's on there already and also so as not to line the intake manifold and cylinder head with oil.

This seems like it should fix all of the issues.



Can anyone see any potential issues with this?

Perhaps the air pressure and temperature?



Cheers for any input before I give it a go,

Miki

I can't see why it won't work or why it might cause issues. I've got the exact same problem as you right now with the blow by issue. Same engine etc. Nothing will "fix" the blow by except new rings + bearings. I recently read, and am running with the theory that the oily mist from the PCV doesn't actually cause any bad blockage in the turbo/intercooler and if anything probably does good lubricating your valves and adding providing a bit of free fuel to the combustion process. I tried a few catch cans and found them to not be that good. Thicker oil also has been working wonders for me. 20w 60 mineral oil.

If you like, I've started up a Reddit group recently called r/1KZ_TE Owners to discuss all this stuff. Come join the chats. It's a bit more active over there. This forum has gone a bit stale.
