I remember reading on another Honda forum (think it was an Accord forum) that you shouldn't use a T right at the engine block because the weight of the 2 senders and the T can break off or ruin the threads on the block. Most recommended using a braided hose and attaching the 2 senders to the fire wall. Has anyone had any issues with this set up?

The threads in the block are not 1/8" npt. There are 1/8" BSPT. They have the same dia, but a different thread design and pitch. If you install a 1/8" NPT into the Honda block, you will destroy the threads. When you add that heavy aftermarket sender the vibrations will eventually crack the block.

There are two ways to add a oil pressure sender unit safely. You need the following adaptor http://tunertoys.zoovy.com/product/O...al_Outlet.html to properly fit the block and offer a pickup point for a a sender unit with an extension line.


Here it is installed along with my cam tower oil supply line


The other option is to use the oil filter sandwich block like this. http://tunertoys.zoovy.com/product/G..._GVC10018.html

thanks doug, u have pics, i was gonna say this when i started reading the write up. I remember reading a few threads and if u use npt fittings on that spot it'll crack and then u have an oil leak. Sandwich plate FTW, tho, isn't it weird that if u use the sandwich plate to send oil to ur turbo ur turbo is getting un filtered oil? my buddy and i were lookin at that.......:director:

Amen... the first time i hooked up an oil pres gauge i hung it right off the back.. After my first pull with the car it was blowing oil out cause it snapped right off..

You def need to do the hose method especially if its a higher revving car.

I actually recommend the sandwich all the time. Im revving past 9k and have 85a mounts and have no problems thus far (*knocks on wood*)

nice write up pax!

Can you get a good oil pressure reading off of one of the oil filter sandwiches? I was under the impression those were only good for oil temp, not pressure.

looks good, my buddy tried to do his with rubber line and looks like crap and leaks everywhere....
