Removing Bung (welsh Plug) From Rb25 Oil Filter Bracket

[PHaT MR30]

As I slowly put my motor back together ive been wondering where to put the sensor for my oil temp guage and I noticed on the oil filter bracket a place where you could possibly put another sensor. however it has a bung in it and im not sure how to remove it. I have a spare one here I can hack into, but i thought maybe someone else has done this already. Looking from the inside there is a gallery leading up to this bung, so anything is possible.

I am hoping that if i can remove it it will either have:

1. nothing behind it and I can tap a thread into it

or

2. nothing behind it and already has a thread tapped

couldn't take any pics as I didn't have a camera with me when I discovered this so i did a screen shot from Nissan FAST for reference.

Note the bung is part code 00933-1141A

Cheers

hmm.. i can't make much from that pic. Could it be for oil pressure?

[PHaT MR30]

oil pressure is on the other side, and im already using that

a sandwich plate would probably be easier.

a sandwich plate would probably be easier.

I would use a sandwich plate, however because of my oil cooler and remote filter setup, leaves bugger all room and probably wouldn't clear the engine mount then.

the plate that goes onto the block for the relocator kit usually have a thread to fit temp and pressure sensors. it might be easier for you to replace that part if yours doesnt have one, or get one tapped into it if you're keen to drill into it.

You can remove the bung/plug by drilling it out slowly, it is not very thick. The hole it covers does not have a thread in it.

I have just done the same as you want to. The oil temp sender had was to small for the for the hole so i took it to a local welder who filled the hole with weld and i just drilled and tapped it to the correct size after.

Sweet! thanks man, thats all i needed to know!

Why not tap a bigger thread into it and then use and adaptor to sleeve it down???

Just a thought.

[NutR33]

The sender i had was only fractionaly smaller than the orignal hole and the adapter for the sensor was quite large.

I was concerned about drilling the hole out large enough to fit the adapter as i thought that there might not be enought material around the hole to be strong enough.

PS i was using Stewart Warner gauges and senders.
