i have non turbo. is it 60mm for both top and bottom or 56 top and 60 mm bottom??

thanks simon

Hi Simon,

The mounting faces on the engine are coplanar. If there is a difference, it would be on the filter mount itself. Both mine and isuzurover's were 4mm out (hence the 56mm and 60mm). It's best to check/measure your filter mount as I understand some have had coplanar ones as well(?)

Put the filter mount face down on a flat surface (I used a study desk), check for / measure the height difference between mounting surfaces and you're done.

Cheers

Another option... Since Bojan and I made our spacers I have seen a couple of engines where the top pipe has been cut and an extension brazed in. So if you are happy to do that it means only one spacer, no new bolts for the top, and the difference in spacing between top and bottom is no issue.

thanks bojan and isuzu rover.
yeah i got the machinists at work setting me some up, for a cheesecake
yep just checked 4mm out so no worries just get the spacer machined down.

This is the option i will be using

I am still on the hunt for the right lump of ally to have some of these spacers made i may have to do them from steel yet will keep hunting

Thought I would just ask this in here then start a new thread.

I was wondering what this hole (circled red, bit hard to see) on the twin filter setup was used for. I ask, because the pipe I got sent to me from the wreckers that goes from the oil cooler to filter housing doesnt have any where to put turbo feed line. If the hole (circled) isnt used for anything, can I use it?



If not, ill have a spacer made up for the top and drill and tap that instead of just extending the pipe.

That hole is for the oil feed line that goes to the timing cover on the front of the motor(truck motors). If yours is an original Landrover Isuzu it won't have this oil line so no reason why you cannot use it for the turbo feed.

Thats exactly what I've done on mine.
