Hi Sambanistas

Redid all my engine cooling, replaced tins - new thermostat, new flaps, wrapped my exhaust. It's right this time!

My oil temp shows 140 after driving it for 10 miles. I thought my guage was bad - but today it actually moved to 140.

I understand I should be running at 180. I used ISPwest's oil pressure block for my oil temp and my oil pressure sender.

After reasearching some other posts - it seems that's a bad spot for an oil temp sender as it doesn't get oil washed over it. It seems too low in its temp vs my infrared thermometer. The case is 160deg.

Should I move it to my fuel pump block off plate? I would need to drill and tap, but would it get enough oil on it to work correctly there?

Thanks!

The fuel pump block off plate will get less oil on it than where it is now, to play along with everyone else's readings it's got to be in the sump submerged in oil, either in the sump plate (add 20 degrees for actual oil temp) or in the dipstick blockoff plate if you have a universal case. Even one of those senders that replaces the bypass valve cap would be better than where it is now.

the type 3 dip sticker location wood be my choice. yes it needs to be in the oil "flow" path or the sump.

Can you please explain this a little more for me? I'm not sure what you mean by this.

Thanks!

If you are running a remote full flow oil filter, you can use a gauge port fitting like the one below and get the sender in the oil flow.

That's a great solution! But alas, I had a filter pump on it that I recently removed. It made it so I wasn't getting oil to my oil cooler.

I'm running a stock 1600dp, no full flow. Dual Kadrons, electric fuel pump. Header.

Marc Tucker mentioned this, I think that means to mount your oil temp send in that location, hence the sender would be suspended in oil. A type three case used in an upright engine could do this.

With your set-up, your best bet would be to install the sender in the oil relief plug.

This is the T I run my senders on. I compare it with my IR temp gun and it is accurate.

Your oil temp should get closer to 200*F to evaporate the water out of it.

Just to verify - that T looks similar to the block I'm using, in the same location? Do you know what sender you used?

Thanks slalombuggy - that sounds like basically the same setup I have.

What kind of oil temps do you normally get with the sender in this location?

This is my first choice also. The sender in the oil pressure port is probably reading the temp of the engine case at that point. I would surmise the actual oil temp is 10 or 15 degrees hotter than what is being displayed. In any case, remember the temp being recorded is the temp before the oil goes through the cooler.

On Bradford's setup there, I would drill and tap the remote filter adapter...oil definitely flows there.

Since i already have a remote filter mount (i have a full flow setup) i was thinking of doing one of these, with reducer plugs and sending units on one side instead of plugs...

The type 3 block off plate, or the sump drain plate are the only other good spots i can think of, but neither are ideal.

There ya go.......all you need is a 1/2 to 1/8 pipe thread bushing. If you can find one. That particular adapter looks like it has a drillable boss on the top of it.

Unfortunately OP does not have remote filter according to one of his posts...

This is the filter mount I always get. Easy to set up for left or right hoses, and bushings for the senders on the unused ports: easy. For a temp sender on a case that is not full flowed there isn't an ideal spot if you don't have the case part to tap the location. The bottom oil valve plugs are ok, but slow to respond to temp changes as they aren't in the main flow of oil. I have seen a pic of the doghouse cooler adapter tapped for a sender, and thought it was a good idea, though I don't know exactly how it fit into the shroud. Nice that you can remove it from the engine to tap and install, so there's no need for a full breakdown.

No oil filter on this engine, remote or otherwise. I'll do a full flow on the next build.

I think I will leave as is - and assume that it's 20deg low. All a gauge really does is notify you of the change in temp, right? I would assume it will still do so here?

The poor guys at ISPwest think this system works well. I hate to bring it to their attention that it doesn't - but will.

Thanks for the great info!

The real issue with trying to to take temperature off pressure port, is that there is no oil flowing by sensor....And temp sender should be submerged in flowing oil.... Really all you are doing is measuring heat from block that has migrated down to sensor...

Thanks for the clarification Dale. Can I pull one of the pressure relief plugs with my engine in place? I have a dual relief case - so the front one, right? Is it a mess of a job? I see Kaddieshack has a sender like this:
