Thread: 4BD1 Provent Install

First step is to remove the factory breather:


The metal tube coming off the engine side plate is a whopping 1.5" OD. The rubber hose on the factory breather reduces that to 1.25" - which is the OD of the breather inlet.

The breather next to the Provent - makes the provent look small!


The tube on the side of the engine:


This is where I will be installing mine. Plenty of room, good location to route piping, and well away from turbo:



I will be connecting the drain to the vacuum pump drain (and replacing the dodgy hose clamps at the same time!):

Turbo install completed! (I wish)




On a serious note, can anyone see a problem with brazing a fitting onto this plate for the oil drain? It would seem the most direct return route...

no input of value for you, but geez mate that sure is a filthy motor

found my head twisting left and right to orientate the photos intot he vertical position too... never done it with a map, but photos need it IMHO...

Photos better now???

Yeah I know - should have cleaned it before I started pulling it down. WA isn't as sandy as people think.

If you mean the plate with the mud splash on it, that is, unless I am mistaken, the oil pump cover, and I'm not sure it gives free access to the sump. You could pull it off and investigate, though.

Ben, that plate sits above the oil pump I've been told. That is where my turbo drains to. I think Justin also put a oil drain on that plate when he fitted a turbo. The factory turbo set up has a drain on the vertical plate (two bolt oval shaped) a bit lower on the motor and to the left. The plate you nominated is more easily accessable.

I was looking at leaving the rubber reducer and fitting a steel section of pipe the same diameter to join up with a hose to the provent. You could just hack off a part of the tube from old set up. Its the right diameter.

I'm interested!
A dirty motor doesn't effect the peformance so what are you complaining about

Thanks Pete. I thought about chopping a bit off the factory breather. I will either do that or make something up from scratch that incorporates a tee for the rocker line.
