Thread: 4BE1 twin oil filter

If you look at the pics of my set up on page 3, you can see that the bypass filter points upwards. On closer inspection it appears to have an adaptor plate fitted that turns this filter upwards.
I'm not sure if this plate is readily available or not but it certainly keeps the filter out of harms way.

That's actually the full flow filter that's pointing upwards. Bypass is the short fat one at the front.

How is the adapter plate attached, and does it look like a factory part, or one that someone has fabricated?

Yes, its pressure at that point, but it has already gone through the main filter and is heading towards the oil cooler.

Thanks Steve! I just spent ages copying and uploading the same pic!!!

So here it is anyway!


Looks like some block drilling is in order for many of us. Shame the sump needs to be dropped to do it properly.

I've got an oil change due around the end of August, so will be doing mine then.
Also a pity the Isuzu sump gasket is around $50 - mine was new 5K ago - but I guess I can re-use the bypass filter, so that saves a few

Could also be a real bummer for anyone with a single piece spacer that's done a heavy duty job of loctiting their threaded rod studs in. I don't think there's enough clearance to the chassis rail to get the housing and spacer off if you cant get the rods out.

Edit: would be great if someone can find a photo of where the turbo block has the hole drilled

Closest I could find searching the net was this 4BD2T photo:



Guess its going to pretty much the same as what we need to do.

Sorry that is incorrect. Oil from the pump enters the filter housing via the hole in the block.

With a 4BD1T, with bypass filter the oil from the bypass filter drains back to the sump via a second hole located in the top left recess where the housing mounts.

Hi
Will take a photo of my 4bd1-t block tonight if no one has done it by then

They look the same as the pic that Steve posted above.
