S16 Oil Cooler Plumbing... Opinions

[Revla 2]

Hi all,

 

Currently i'm running my water cooled oil cooler using the Mi16 thermostat housing outlet and the

spare fan switch hole by the bottom hose.

 

I've been thinking about getting a new top hose with the cooler pipes already plumbed in (as on the PAS 205's/ 309's). The reason for this is:

 

1. I think the oil may get too hot too quickly.

2. Its darn tight down there for the filter etc with a pipe running from the rad to the cooler....

 

Any thoughts appreciated!

 

Cheers

Bloody odd you should post this trev as I was only thinking to myself yesterday wondering what oil cooler setup you are running! The best option is to junk that oil/water cooler/heat exchanger and run a 1.9 8v air to oil cooler. They work much better and you can junk all the extra plumbing thats on there. Hour or two to fit once you have rerouted the plumbing.

 

My oil temp climbs way too quickly too and its not a good thing. The original 8v air to oil cooler keeps things cool but its not so big that the oil never warms up. You will also notice the engine operating temp being lower too!

I'm also ditching the water pipe that runs over the exhaust manifold, and going for the late 8v housing.

This kills 2 birds - 1, No pipe out the back for the pipe mentioned above and 2, A nice coil mount.

And going to use the 8v water distribution block which sits on the back of the lump.

Doubt Trev's engine will run any cooler as he's got a SBC 72 degree thermostat like me.....

Diddnt know that! Ok, you wont really experience the engine running cooler, just the oil temp being lower,

Some people (SBC) prefer the water cooled jobbie to the air cooled.... they'd replace a standard air cooled with a larger Mocal cooler, but leave the water cooled alone.....

The only reason for the heat exchanger is to heat the oil up quicker to help MPG and emmissions, I would ditch this myself for a competion car or if used on the road it's worth keeping

 

I also always ditch the rear pipe that runs over the exhaust, As i say the less pipes you have the better and I think 1 is no longer made any more

In my opinion/experience the standard 1.9 air/oil cooler is a waste of time - it's hopeless at keeping the oil cool on track or when giving it stick for a prolonged period, and thanks to the lack of oilstat it delays the oil warming up in the first place which isn't desireable on a road car in winter.

 

For a road car I'd use a water/oil heat exchanger as that'll help bring the oil upto temperature quicker, and keeps the oil temperature reasonably steady for anything other than prolonged thrashing. For a track car I'd do the job properly and buy a proper air/oil cooler from someone like Mocal, preferably with an oilstat.

 

Finnned alloy sump from a Mi16 will help keep the oil temperatures down as well and worth considering as it's a straight swap on a 1.9 8v.

A finned sump & an oil cooler (of any type, oil water or air oil) will keep it too cool imo for most circumstances except on track. With this set up on mine at Cadwell in November my oil temp didn't get above 1/2 way round on the guage all day. On track in summer it might be much better though.

 

I had this on mine & have recently removed it as I had hardly any oil temp showing even after a half hour drive.

 

I've gone for an 82' thermostat & the oil water heat exchanger & this is much better at this time of year.
