Hi,

Has anyone heard of sending oil (from the oil cooler) direct into the main gallery though (enlarged) oil temp sender location?

Even better, anyone done this?

Cheers.

So your talking about taking the oil coming out of the oil pump and putting an oil cooler in the line then putting it back in at the sender??

Wow.

Cheers.

i was looking at running an external pump for oil and vaccum, and i did look at pumping the oil straight into the sender hole, i see no problem with it.
would probably tap it to 3/8 NPT or bigger if possible, but the only way to know is to get a junk block send a drill through it.

also, i dont think you added anymore aerated 202 pic's into the blowup thread!!!!!!!

One I'm putting together at the moment is drilled and tapped 3/8 bsp, there's enough meat there to do it safely. I also drilled the short passage behind it out to 1/2" though it's probably not really necessary. Could take a pic if it helps.

Not really that dramatic. I already have an oil cooler so once the oil is on its way back from the cooler why send it back through a (ugly) sandwich plate and internal oil galleries when you could reasonably simply put it (with more flow) straight into the main gallery?

This wasn't my idea but suggested to me. Intially I was a bit negative, hence the post, but the idea is growing on me.

Cheers. I've been told offset machine 1/2" NPT. Yes, will have a good poke at a junk block here first.

&Yes, keen to avoid those air cooled motors! :banghead:

(no offense to the VW or Porsche crowd intended)

Hi Oldjohnno,

I'm going to have a look at car that has already been done (offset 1/2 NPT as per above) shortly, but a pic would be nice if easy enough for you.

Cheers.

Is there a reason you need to run the oil cooler??

I fully understand sticking the oil there, Just not certain why you want an oil cooler??

Cheers.

3/8" bsp with passage behind it drilled out to 1/2". I'm sure this has been done a million times before, as you can see there is plenty of material.

Bomber - Temp in the sump (with the oil cooler fitted) is 120 deg. I'm all for simplicity, but i think the cooler is a good idea. You don't think so?

Oldjohnno - Thanks for pics. I'm sure it has been done heaps, but new to me. Cheers.

I think its added complexity where a larger sump with an extra litre or so would give similar results.

I agree to a point - I'd certainly avoid running a cooler if it was at all possible. But extra sump capacity only helps slightly because of the bigger surface area exposed to the air flow, the bigger oil volume on its own will only increase the time taken to heat the oil, it can't make it run cooler. The ultimate system may be an off-line cooler circuit that uses a small (possibly electric) pump to circulate oil through a cooler and filter, completely independant from the lubrication circuit.

For reasons that I don't understand the little sixes seem to be pretty good oil heater-uppers, especially with a few rpms. It's interesting (though possibly entirely irrelevant) that one of the symptoms of torsional vibrations in a plain bearing shaft is a dramatic increase in the temperature of the oil flowing from the bearings.

I may be to used to 400m sprint races and street use then....

I just like the idea of having oil go from my pump to the main galley with minimum crap in the middle, the idea of putting an oil cooler in there irritates me.

The idea of a seperate system is rather interesting, im wondering if a dry sump setup would be quicker/easyer/cheaper though?? Run alloy lines from the front to the back (where the tank is) and that will be lots of cooling area lol.

Cheers.

+1 agree entirely. But if the oil gets hot enough to deep-fry a Chiko you have to do something.

Hmmm, I wonder if you could put one of those wire chip-basket thingys in a dry-sump tank and run a vege based oil.....

Have a large sump. Pretty much as per Oldjohnno when you have to do something you have to do something.

Plenty of gearboxes and diffs cooled as per your description above. Wouldn't really be a lot more work over a conventional engine oil cooler set up.

ive got the external set up on my lc. i run an external oil filter and an accumulator all you would have to do is add the oil cooler in after the filter housing. as for the block mods im pretty sure i have pictures of the t piece fitted in the oil sender spot and also the extra oil feeds at either end of the block in my signiture thingy on photo bucket.
you can pretty well turn the standard high volume pump external with an external pick up and stuff not a huge job ive got photos of that too if you want to have a look..
