<html><body><div style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 10pt; color: #000000"><div>When starting road racing (circuit racing) I had an oil cooler in my car just like about everyone else. The oil T° was always low, less than 100°C/212°F. In 2010, to get my car nearer the minimum weight, I removed the oil cooler and I'm racing always without the cooler since then.</div><div>Can't say that the oil T° is higher without the cooler, maybe a little bit, but still always lower than 100°C , even after 1 hour races. I'd like to have the oil T° a bit higher! So I believe most Triumph TR 4 cyl cars don't need an oil cooler at all, maybe the oil T° is remaining too low in sprint races. There are only 3 main bearings and 4 big end bearings to heat the oil by friction. Compared to a modern engine, the oil isn't heated up much by the distribition parts and in the cylinder head. About 80 bhp / litre is a lot for our old engines, but I think the modern oils have a rather easy life in it.</div><div>Marcel</div><div><br data-mce-bogus="1"></div><div><br></div><hr id="zwchr" data-marker="__DIVIDER__"><div data-marker="__HEADERS__"><b>Van: </b>"fot" <fot@autox.team.net><br><b>Aan: </b>"Bud Rolofson" <levilevi@comcast.net>, "Kas Kastner" <kaskastner@gmail.com>, "fot" <fot@autox.team.net><br><b>Verzonden: </b>Donderdag 6 december 2018 06:11:12<br><b>Onderwerp: </b>Re: [Fot] Was: Oil Cooler or Oil filter first?

<div>On your oil pressure situation, here’s a couple fuzzy pix of the
<u>adjustable</u> oil pressure relieve valve my brother Buck made up many
years ago on my Spitfire. He drilled out the end of the stock valve and threaded
it to take a fully threaded bolt (no shoulder) on which there is a nut. The bolt
itself is also drilled out to take the stem of the valve’s plunger and spring.
Then, loosen the nut, with engine running turn the bolt until pressure is where
you want it, tighten the nut against the end of the valve. I run about 80 psi at
full throttle.</div>

<div> </div>
<div>And here’s my oil line setup. Oil comes out the side hole in the adapter,
to filter, into/out of cooler, through checkvalve, back to engine through center
hole of the adapter. A Tee in the cooler lets me install the oil temp sensor – I
want to know the temp at its hottest, not after it’s been cooled. Another tee at
the engine adaptor feeds the Accusump. It’s been a trouble-free system. I got
the Earl’s hoses with the screw ends because the Tees have to go in first and
then there’s no room for the hose beside it to turn. --Rocky

<div>
<div> </div>
<div>Thanks to all who responded about this. The consensus was to go to the oil
filter first to catch as much debris as possible before it collects in the oil
cooler. Everyone said with an exploded engine (like I experienced) replacing the
oil cooler is a requirement.</div>
<div> </div>
<div>So I did replace the oil cooler after blowing up the engine, but TWICE I’ve
had them ($160 Earl’s oil coolers) blow out and leak all over the engine bay
when doing a test and tune day at the track. I’m on my third oil cooler and
trying to reduce the oil pressure that on my gage says 85-90 psi to see if that
is what is causing the coolers to leak, although they are rated at 150 psi or
more. I put an extra copper washer on the oil pressure relief valve but I’m not
sure what is really causing two oil coolers to blow out. Bad luck? Coincidence?
Bad parts? I’m getting tired of oiling/cleaning my engine bay. I’ll find
out if my washers help on the next track day cause it has happened after 4-5
laps the last two times when I was breaking in new rings. Unfortunately the next
track day could be a couple more months.</div>
<div> </div>
<div>So the next question I have is how to know which way the flow is out of the
adapter on the engine. See pic below and please tell me if the oil is coming OUT
of engine from the right or left fitting in the picture. There are absolutely no
markings or clues to tell me.</div>
<div> </div>
<div>Also do most of you measure oil temp on the oil coming out or going into
the engine?</div>
<div> </div>
<div>Thanks</div>
<div>Bud</div>

<div dir="ltr">Go to the filter first so any junk in the oil does not contaminat
the cooler which is almost impossible to lean completly. If you ever have any

count on having to replace it also.<br clear="all">
