I see some people mention that they use them, and many others dont mention anything about them in their builds. But from my point of a view they seem like a GREAT idea. Nice and easy way to run an oil line to the turbo as well as an oil pressure gauge. But are there any short comings of the sandwich plates? Is it a bad place for an oil pressure gauge to be mounted?

Still gettin parts for my build together as well as window shopping for other stuff i just want. But they seem like a good idea.

 

There is nothing wrong with an oil sandwhich plate. They work great

 

you dont think providing unfiltered oil to a turbo is a bad thing?


i surely do...



now if u said specifically a GE sandwich plate, i would agree that theres nothing wrong with that.

 

Most sandwich plates provide filtered oil to the turbo. most and maybe all do.

 

I run the GE unit. However, how is oil not filtered? If you have an oil filter on a motor, the oil all runs through it sooner or later. How is there a better path for the oil to flow? It's a closed system. Learn me something.

unfiltered oil flows to the filter (duh), and filtered oil comes out. most (i donno about GE's) oil sandwhich adapters ive seen just bleed off oil before it hits the filter, so you wind up having oil that wasn't just freshly filtered going to the turbo. im not even sure why people bother with them, tee'ing off the oil pressure sensor is just as easy and gives you filtered oil.

 

The motor oil passes through the filter before it makes its way to those ports on most sandwhich plates. I personally run my oil feed off the stock oil pressure sensor location. that pressure port is pre filter and its worked fine for me for years

 

If you have enough debris to cause problems pre-filter you have bigger things to worry about. I loved my sandwich plate. Made everything real easy and no worrys about shitty brass fittings snapping off off the stock block sensor or Teeing **** everywhere to make it work.

 

maybe some, but not most. i ran a generic and then a glowshift oil sandwhich adapter and i eventually blew two turbos, and garret told me there was oil contamination in both of them. switched to a tee off the oil pressure sensor and never had another prob with that

 

Yeah? I had oil coming from the stock oil pressure sender location to and when it was sent to get rebuilt, cause of failure? Oil contamination. Go figure.

 

filtered oil is sent to the oil pressure sender, so if yours failed because of that, you have other problems lol

 

No its just an excuse for Turbo companys not to warranty your turbo.

 

i guess it was just a coincidence that i never had the problem again after switching feed sources on that setup

 

GE is the only filtered sandwich plate

 

i stand corrected its post filter on the stock location, good to know, probably why ive never had an issue lol thanks Boostblufg2

 

glad to see you came around.


its very easy for a small piece of RTV to free itself in your motor, and find its way into your oil line, maybe getting stuck in a restrictor, or something like that.

ive seen it plenty of times


anyone who thinks "most" sandwich plates offer filtered oil have NO EXPERIENCE. but thats fine.



ive used the OEM sender port for every build ive done and i have never had a problem. KISS at its finest.

 

I never really thought about that, good info welfarepc.

So if i do choose to use one, i should go for the GE one as it is post oil filter going to the turbo?

What about Bisi's sandwich plate ( http://bisimoto.com/store/index.php?...roducts_id=540 )

 

sorry to bring this back, but i just wanted to make sure that the stock oil pressure sender location uses filtered oil. can you explain or show how you know for sure that its filtered? if it isnt filtered, using the generic sandwich plates would be the same thing right? thanks

 

It is filtered because IIRC the galley that leads to that port is post filter.

I lost a brand new Bullseye turbo to unfiltered oil on my fresh 75.5 Vitara setup. Now I have the oil coming from the stock port on the back with an FP oil filter in line for extra insurance.

 

Running an MFactory block adapter and just lost a Garrett turbo do to contaminated oil. Think I may have to switch to Golden Eagle Mfg. :O

 

Im running a Xenocron remote feed line from the OE pressure sender, 3 years and still not 1 issue.

 

I'm well aware of the date but....in essence get the GE one or remove your stock oil pressure gauge sensor and use a npt or what ever fitting? would like to know what NPT/-AN size too. got a free BWR one but I'm a little scared to loose my new PTE 5858 will be using motul oil only tho if that matters.

 

I wouldn't worry about it either way. You have a Precision turbo. The bearings are gonna fail, and no matter which sandwich plate you have, they'll blame it on particles in the oil.

 

The only plate that sends filtered oil to the 2 fittings is the GE. If you run a feed line off of the stock pressure sender location then you're sending unfiltered oil to the turbo and need an inline filter.

Although if your 5858 has a steel thrust bearing and collar (99% chance) then it'll fail sooner than laterregardless of what you do

And why bump an old thread with inactive users for information everyone already knows

 

Its actually a 1/8th BPST fitting IIRC. You will want a T if you want to grab oil pressure off the same line. Mine has a T, 1 line goes to firewall where oil pressure sender is mounted (dont want to hang oil pressure sender off the end, can break off) and the other to turbo.
