Chris,

I am running an external oil coller with a sandwhich plate oil filter adaptor. Will this result in more oil taking the external oil cooler pathway?

I've been running my race engines with the secondary relief blocked off completely.
Since many engines were produced without it, I tend to think it isn't really necessary.

It won't have any effect on oil flow to an external cooler through a sandwich plate.

Would this be a beneficial add to a stock motor internally?

If you are experiencing high oil temps/low oil pressures - yes.

Chris,

I couldn't find the place to submit an order....

Ordered one.
I think my car has (or has had) just about one of everything Chris makes except the exhaust.

Nothing but quality stuff from Chris. It is a love hate relationship. Love the stuff but hate you can't buy every part he makes!

found the link and submitted order.

Showing my ignorance here, I try and not spend a lot of time under the car:
Can the install be done with the engine in the car? From pictures I've found the valve seems to be to the right of, and pretty much even with the lower edge of the oil pump. Is there room to swing a ratchet wrench and remove/install the mechanism without fouling the bodywork or something?

Thanks,
Harvey

Just ordered mine, thanks again for the great products Chris.

Its an easy install with the car on jackstands - as long as you can get a big-ass flat-blade screwdriver on the cover.
Probably takes 15 minutes, including jacking up the car.
I'll be photographing an install later this week.

Thanks! Order placed.

I don't know about the 15 minutes though....

I guess if you haven't dusted off the jackstands in a while it could take some time.

Excellent!

My machinist is doing a pilot run of 20 sleeves right now - you're #17.
I hope to start shipping assemblies tomorrow.

Just ordered mine.

I'm looking forward to people's results! Great innovation!!

I just placed an order for one! Can't wait to get the motor all together and put it to the test. I sure I'll be happy with the results!

Received today, included instructions seem very clear. Thanks.

Looking at the parts breakdown it appears there is a copper crush washer on the cover screw. I would think this is something that should be replaced when reseating the cover. Just go to the local FLAPS and match up a new one or ?????

Thanks again,
Harvey

Most of the crush washers are aluminum.
We re-use them several times without encountering leakage problems.
You may not find one that fits at your FLAPS.

I think the first 3 were shipped before I had the instructions ready.
Anyone who didn't get them, just email me and I'll send electronically.

Mine showed up today.
:-)

I have been wondering how this worked for you guys?

wellllllllllllllll

I've been dying to get out and drive after I installed it,
EASIEST INSTALL EV, ER!!

I need to get tires on "Beauty" to test,

I have having problems when after ? 30-45 minutes?
temp. would race up to 260-270-280- no prob. ??

I've been pondering the problem for the last few years, Why?
I'm confident, Chris got it!

Installed mine 2 weekends ago now.. immediately the hot oil pressure drop was fixed. Oil is running cooler too. Took me about half an hour to put in.. Not rushing and having a beverage while working away. I re-used the aluminum crush washer with no leakage issues. Great job Chris. !

Any more people put in Chris's relief valve?

How are your oil temps?

so far, it's been an interesting experience for me to observe.

I notice a few different things.

Now I've done plenty of oil changes in a 914,
since 1985.
Green Machine My first and still own, 914.

Install EZ, thanks Chris!

I checked the old oil relief SS plug,
It has nasty scoured scratches on it.
Hmmmmmm.


Now I add oil.
Put in what I thought was correct amount,
I've almost a quart over??

well I'm excited to get the engine running,
I can drain it later.

Start her up 70-73 lbs of oil pressure.
Normal.

I let her run for an hour, checking everything,
(Beauty is up on jacks)
Temp. finally gets near 180.

Good enough for me!
And oil pressure is at 40 Lbs! at 1200 RPM idle.
Is this ok?, I'm happy with it.

Now the weird part,
I go drain some oil to get it down to ,what I thought was the proper level,
being under the 914, guessamating about a half quart.
check oil level, no change.
Dang, so I say myself, drain a lot and you can always put it back.
No prob. drain about a quart and some.
Oil level perfect, I have been adding an extra 1/2 qt.
So I go about so with fresh drain, what I thought was fresh oil,
It was BLACK!
I go to strain it thru paper towel (took FOREVER)
nothing,
Well I didn't reuse the oil,
but I think what Beauty has been suffering thru,
was the plug was stuck in cold position, sorta closed off the cooler,
allowing the soots of hot burnt oil build up in the cooler,
as less flow, easy deposit?

I'm not complaining,
I cannot wait to get it on the road for Road test temp.check.
But I'm very busy with work,up till end of year.

I have a stock 74 2.0 and am in FL. It's close to 100 degrees right now and have been considering adding a second oil cooler to my car. Let me know
