This is a common problem with 1uz into hiaces, the throttle body hits the lid right under the drivers seat/ buckle anchorage. The best way to sort those out is move the throttle body to the other side.

 

Or start with a Super Custom/possibly just use Super Custom engine covers

[cletus]

Yeah was going to say that but I couldn't remember if the SC covers fit on a normal hiace, from memory the rear firewall has a bump in it that others dont as well? Theres a few advantages using a SC to start with I think

Yeah good point about the bell housing cover, unsure if it'll bolt into a a tradie Hiace without trimming the floor back a bit.

Super Custom (1KZ at least) has the same engine bay and covers as the factory 1UZ ambulance.

[Jeffs_Emporium]

I did look into whether the engine covers differ for the different engine (y series stands straight up as opposed to the slanted 5k) but part numbers are the same for both chassis. Part number does differ for floor shift vs column however so could look into that to see if it bulges higher or not. 

[Abarth]

Is it true you can’t have a vented oil catch can? Has to be plumbed back in now?

[cletus]

Depends 

If the car has had an engine swap= have to apply emissions standard 

https://lvvta.org.nz/documents/standards/LVVTA_STD_Exhaust_Gas_Emissions.pdf

Emissions standard requires operational PCV system in a lot of cases 

 

If the car has a modified original engine= emissions standard not required to be checked

Any tips for an operational PCV system when running ITBs? Can I run the recirculated gases into each trumpet (somehow) or do I have to drill the manifolds?

[cletus]

Yeah that's a real prick to do 

One company that does a lot of cars with ITBs fits a pipercross filter, and puts a fitting on the back side of the filter assembly to vent into 

 

Otherwise I guess you would need to make a little manifold from all 4 intake runners into a pcv valve

Some people use a vacuum pump

Getting vacuum isn’t an issue, just how to get crankcase gases back into the engine after the air/oil separator?

With a pump you dont have to, just blow them into the air

Pretty sure it has to be recirculated into the engine to get a cert?

[SOHC]

Pipe it into the ait filter

[scooters]

Body lift = cert

Diff drop kits are these a cert item? 

pushes the front diff down 1" after lifting a vehicle to correct C.V drive angles. IFS vehicles surf, 90 prado etc... 

 

 

 

[cletus]

Yes diff drop would need cert

So venting into the enclosed filer assembly is good enough? I don’t necessarily have to tap into the manifold/runners?

[cletus]

I think if its enclosed,  that's good enough. I've passed quite a few cars with that setup

Banga/Cletus can you confirm/expand the comment re circulating PCV gasses back in to the engine for a cert?

The link Cletus posted on the previous page covers it pretty much - https://lvvta.org.nz/documents/standards/LVVTA_STD_Exhaust_Gas_Emissions.pdf

2.3(1) is the section to look into.
