I also have a sandwich adapter for several years now and I'm pretty happy with it. Mine has 4 ports on it.

FWIW, I put an oil temp sensor in line with the turbo feed line, and while it is not totally useless, it does read low and change slowly. In my case the sensor is about 12 inches away from the OPG port on a -4 AN circuit, but there is a restrictor in series at the turbo, so relatively little oil flows past it. In the datalog I can see that OILT follows CLT but ~30F lower.

This is how mine is plumbed:

I'll definitely look into the AN fittings. I don't really like having all the adapters. It's not the clean look and like others have said has the potential to have lots of leaking. I'm planning on pressurizing the setup before I install to check for leaking.

I also have an in-pan oil temp sender so once the setup is in and running I'll post up findings on temp in flow and temp in pan. That won't be for a while though.

So, went with the advice on the An fittings and definitely agree that it was great advice. I used 3/8 to 4an fittings. I don't have pics of the complete setup because the gauges just came in with the sensors and I haven't put them in yet.

If that hose is rubber, you are going to want to keep an eye on it. Over time, oil swells and deteriorates rubber, and peak pressures of 90psi cold aren't going to help either. I have had to rebuild my engine twice because of rubber failure by oil saturation. Ideally you want to use braided SS Teflon lined hose. Using those hose clamps with high pressure is asking for trouble.

+1 I understand completely and agree with this. I only have rubber coming from the engine to the distr. block and SS lines coming out around the back of the engine. Ideally I want to have SS lines completely but I can't find a BSP to 4an fitting for the engine.

Anyone know where I could find one? I have a 96engine.

Found in a thread by searching 'oil pressure sender thread'... first link I clicked on.

The whole point of using an fittings is to eliminate hose clamps. Those look like truck air brake fittings.

^^^ If you're refering to the silver elbows, I'm not sure what they are but they came with the Begi kit and fit and seal perfectly with 4an.

Because of positioning there is not enough clearance between firewall and the metal coming from the shock mount to run AN elbows. Sometimes you gotta improvise.

Thanks for the link

I was thinking about a similar setup, only I wanted to add an oil pressure switch to drive and emergency light/buzzer to let me know if I have catastrophic oil failure.

Faeflora 01-19-2011 02:01 PM

That's a great little distribution block. Ebay just keeps getting better and better.

Faeflora 01-19-2011 02:05 PM

BTW also thank you for the pic of the VDO sender fitament. I was going to tap it in the oil sump but I might go this route instead. Regardless, those blocks are useful.

seraph 01-19-2011 02:46 PM

The sender that's pictured is the stock one. I got the vdo sender in today so i'll post pics of both senders and temp sender tonight. It seems like this setup will work well as long as everything sealed right (fingers crossed).

Wut?

What's this one then?

I have that long neck type of sensor.

The long neck sensor is the Temp sensor.

Here are some pics of the complete setup with stock press. aftrmkt press. and aftrmkt temp senders. SS lines from block to turbo with AN fittings.

I snaked the SS line going to the turbo between the brake lines, so I wrapped it up for added protection.

Because of location I had to remove the stock windshield washer resivoir, so with some ideas from CR I added this.

[IMG]http://i807.photobucket.com/albums/y...a/IMG_1770.jpg[/IMG]

Plenty of space between sensors and win. washer tank.

Overall I'm happy with the way things worked out. I think it will be exactly what I need for my setup and will make it easy to reach any of the sensors if there is a problem with them. I also feel better about it all not dangling from the T coming off the engine block.

Hey I didn't give you permission to use my tank ideas.

My catch can setup:
