Using Two Oil Sandwich Plates?

Has anyone used two oil sandwich plates before (on top of the stock oil warmer / cooler) and has it caused any clearance issues with the fitment of the oil filter? My skyline is in a million pieces (engine out) at the moment so I can't have a look and estimate the clearance.

I know it's not ideal using two as its just another point of failure / leaks, but it will make my life easier :P

Cheers

No I mean two sandwich plates in addition to the stock oil warmer / cooler. I have an oil cooler to install with a built in thermostat in the sandwich plate, so it doesn't have room for the 1/8" NPT sensor holes. I need to install an oil pressure sensor and will possibly install another oil temp sensor down the track so i will need a second sandwich plate with the sensor holes.

I realise I could get rid of the factory oil pressure sensor and install the new one there, but then I would need to find a BPT to NPT adapter to fit it, and the (crap) factory oil pressure gauge would stop working, which whilst pretty much useless would annoy me to not have it working. I think you can get a BPT adapter with a tap for both a BPT and NPT sensor, but I havent been able to find one anywhere.

Ok, most common thing to do is get a relocator kit. Then the oil filter relo plate has the bungs u require

That is the third and probably smartest option :) - but if I did want to do go with the 2 sandwich plates do you think I would have a clearance issue between the oil filter and the drivers side wheel arch? As my engine in not in the car I cant visualise it.

I am just looking the oil filter now and I do use the smaller R34 type ones, so I am pretty sure there will be plenty of room.

Just measured up the Nissan R34 oil filter against a Z145A, its about 1.3cm shorter so I think there will be plenty of room with the 2 sandwich plates whilst using the smaller filter.

Can't you just drill and tap some holes in the thermo sandwich plate?

I thought of that but there is only a small area where that might be possible, and its kinda recessed and on an angle:

Not sure it how well it would work.

1/8 npt into 1/8 bpt won't seal?

Or tap pressure sensor hole to npt then use a tee?

Curious myself

Found this but don't ship out of US

I use two on my boat.

one for oil supply from dry sump + sensors

one mocal sandwich plate for thermostat - attached to heat exchanger

No dramas in terms of "its just another point of failure / leaks"

Not sure on clearance issues tho...

Using an RB25 in a boat = awesome! :P

I'm going to order one of the Just Jap items linked to above, I think clearance will be fine.

Thanks everybody.

Hi all, I've just ordered a Driftworks oil cooler kit with the Mocal thermostatic sandwich plate, which doesn't have sensor points.

I have an existing sandwich plate for Defi sensors and I'm wondering if I can run both at the same time? The car is an R34 GTT with the Neo engine and standard small Ryco Z422 filter.

The other option is to add an extender piece (?) between the oil cooler sandwich plate and the braided line where you can hook the sensors but I'm not sure if such a part exists?

NOPE

the threads are incompatible, but they are close enough that you can force it in. however that means you have over stressed some of the threads and it could develop a leak at any time. Which is probably a bad idea if you use it where you care about the quality of the seal, for example.. in a pressurised oil feed!

to answer the original question, in a GTT I don't see how clearance could be an issue. I reckon you could stack 5 or 6 sandwich plates before you have any issues.. there's a ton of room!

      Does anyone know whats happening with harness on drivers door?

      The two diagrams are equivalent. The R32 one is just one sheet out of about 3 showing everything in the whole car all at once. And without knowing the functionality that occurs in the modules, they are both equally opaque.

      Thanks for your reply,  Those blue/green wires running to the actuator aren't attached to anything, so I'm not sure how the central locking is still working. I will have to take a good look tomorrow, I don't have the car with me. After googling it seems like a pretty common aftermarket actuator which even uses the same green/blue wires the immobiliser required. i'll test everything tomorrow and if it's working i'll melt the solder, strip it, resolder and neaten it all up with some heat shrink. I don't have to understand it if it works hahaha I just don't want a fire/ short circuit. That R32 diagram looks more like a continuity chart? Can you make sense of this form the R34 manual? 10V is probably due to very flat battery, i'll recheck as well tomorrow, I did have to jump start it haha. Thanks again!

      So, COM doesn't mean comms. It means common. What common itself means will depend on the type of device. For a two directional actuator (ie, one that can push and pull on the same output rod) then the common will typically just be the earth connection. There will be at least 2 other wires. If you put 12V on one of the other wires, then the actuator will push. On the other 12V wire, it will pull. Can't quite make out what is going on with the wiring of your actuator. It appears to have several wires at the actuator plug, but there only appears to be 2 wires where its loom approaches the door control module, with at least one of the others cut off. I don't know these actuators off by heart. I'd have to look at a wiring diagram for one before knowing what the wires were about, and that's despite me having to replace one in my car not all that long ago. Just not interesting enough to have dedicated memory set aside for trivia like that any more. That actuator is an aftermarket one, not the original one, which probably died and was replaced. That might require some sort of bodge job on wiring to make it work. Although nothing should justify the bodginess of the bodge job done. As to the soldering job on the door module's loom plug. Ahhahhahaha. Yes, very nasty. Again, I cant tell you what any of those wires do. You'd need to study the R34 wiring diagram (if you can find one that shows the door module). I don't think I have any. I'd have to study the R32 diagram to start to understand what mine is doing, and again, even though I've had a problem with mine for the last 25 years (where it locks the passenger door when the driver's window reaches top or bottom of travel) I'm just not interested enough to try to to work it out. So long as it's not burning down, it's fine with me. Here's the R32 GTR diagram, which, confusingly, has rear door lock actuators and window motors on it!! As you can see, unless you understand the functions of the door lock timer and the power window amplifier, you'll never be able to work out how it works just from the diagram. I don't imagine that the R34 one is any better. Hopefully an R34 aware bod can help. FWIW, the two wires that are cut and joined look like they are both power supply - so hopefully it is not fatal to join them. The 10V you measured on the cut off free end of one of them is concerning. You'd expect 12V, and it might be the reason for the bodge job joining them together.
