Oil Cooler for SC400

[Lextreme II]

I had a closer look at the SC400 oil filter and oil filter housing. From the front view, there are two 12-14 mm allan screws. Looks like we can tap into them and run lines to and from an engine oil cooler. Have anyone try this yet? I think the SC400 was created for this function.

I looked at this fitting some time ago and removed the cap head fplugs. mentioned.

From what I could see you should be able to install tails in the fittings and run a cooler line.

I'm not 100% sure the internal diameter of the fittings would be big enough.

You could always look at having the filter mount bored out to a larger fitting size.

I will have a closer look. I think its big enough for oil cooking route. However, I am not sure which one is the oulet/inlet. Its in metric perhaps i can convert it to npt. I would think a 3/8" npt (1/2" hose) would do the job. Finding metric fittings is very difficult in the US. However, this can also serve as a source for turbo/supercharge oil supply too. Very interesting setup from Lexus for thinking ahead.

It won't matter which is in or out from the oil coolers perspective.

It will matter if you want to source anoil supply from it.

I think the fittings are there as part of the machining of the mount. I think they needed to drill from the front and simply blocked it off with those handy fittings.

You see it in engines as welch plugs and bolt on plates.

Rod,

I double check today (forgot my camera) and the two plugs are was made or prepare for external oil cooling or remote oil filter. The SC400 is different from the LS400 oil housing and configuration. The two holes is about 16-18 mm. Its perfect for remote oil filter or oil cooler. I was taken them out, but the dead engine oil was not drained yet, so i put them pack.

I removed the filter mount and made up a 12 mm alloy plate to match ,drilled
and tapped two 3/8bsp to -8 fittings this morning.I will then run an external filter mount and cooler.Trying to open up as much area as I can for the turbo pipe work.

-8 lines and fittings are a bit on the small side for oil lines. -10 or even -12 would be a far better choice.

To Dave, the two threaded ports that you are talking about would work, but you will have to totally block off the original filter and run a remote unit or a large portion or the oil would not be filtered. now you could also use a remote unit an the stock one at the same time, but a portion of the oil would not go to the remote unit and cooler.

The block plugs are there only to cap off the drilled passages to link the filter area to the inlet and outlet where the adapter attaches to the oil pump housing on the front of the motor.

Found the answer... a relocation kit would work..http://lextreme.com/forums/showthread.php?t=5240 The reason i do that so my turbo pipe would clear the oil filter. I was thinking about thread the oem housing from whatever to 1/2" npt and run 5/8" hoses (about 10-AN) for the oil cooler and filter.

This is my setup below 1/2inch bsp to -10an

We only talk in metric down under in NZ, so i went what is BSP and AN did a google came up with this site, it has some useful info, so thought i'd share http://homepages.tesco.net/~A10bsa/isofgo.htm .Covers BSP, Metric , allsorts of threads, and usefull data someone may find it handy as i did.

Ah good work Lambo, I'll see your bolt and thread link and raise you an Screw joint torque preload calculator. http://www.tribology-abc.com/calculators/e3_6a.htm

 

[Lambo]

Thanks for the link, i wonder if David could put a section on the site where people could drop links to really usefull info like the above. There is so much good info out there and sites that individuals have found that would help other members.

Yes very good idea.

Just a library of links with a very brief description

I think we can create a sticky for it.

That would be a good idea David then we can post a link to those sites or howtos that we all find in surfing or tech items like above.the information is out there finding it when you want it is another matter.

I'd vote against a sticky. Too many sticky's clutter the Forum.

I know I have a few handy Sites for calculating boost, injector flow (by part #) transmission gearing etc.

If we had a sub-section in the tech section we could forward it to the appropriate person for inclusion.

I don't think we can trust people to not dump the wrong sort of links in there. Mycarspossedme's link on screws could take on a hole new meaning (pun intended).

 

[Lambo]

Yes Rod good idea if its under the Tech section we will all know where to find it, and a Moderator can control what is entered.As you say we don,t really want any screwups.

Here's a pic of my finished oiling system

 

[Toysrme]

Late as usual. I've been pimping this to the v6 people for awhile now.
I did mine forever ago (Cost like $5-10 bucks to do).
I love it. Instant taps for oil ports, easy to add a cooler, etc.




Needed:
Four - 3/8" barbs (3/8" = 9.5mm)
Four 3/8" hose clamps
6' 3/8" Fuel/Oil hose
Ultra Black RTV
You will need a tap for your barbs if you don't have one. $2.50 shipped - ebay

Instructions:
There isn't anything to say that isn't obvious. Take the stock Toyota oil filter stand- off & cut it in half. Tap (& drill if needed) the channels to accept your hose barbs. Put your sealant around the threads & tighten (15ft-lb, or pretty hand tight is good enough).
From there you have the one end that bolts to the block & the other that has the oil filter. You can relocate it anywhere you want. You can easily add dual filters, and/or an auxiliary oil cooler.
The half where the oil filter goes is pre-tapped with two plugs at the ends of the oil channels. One can be removed to install an oil pressure fitting, or a hose barb (1/4", or 3AN) if you need a turbo / supercharger oil supply.
********************
For people not able to drill out their own channels, it may be hard to find 3/8" barbs that do not require drilling holes out before tapping them. I had my local Nut & Bolt house order me some to my specification. (9/16"-18 NPT w' 3/8" barb)
*Note* If you're not afraid of under sizing the , 5/16" barbs are very common. The thread size is generally 9/16"-18 thread. The tap will fit straight into the oil channels without drilling.
So if 3/8" barbs are unavailable, you can always try common 5/16" barbs. (0.375" VS 0.3125"). I wouldn't add a cooler on 5/16" lines, but otherwise there shouldn't be a problem.

Great job Toysrme... Actually i got a relocation kit. I will post some pictures later.
