I found the right drill and tap for my autometer gage oil pressure sensor, and I wonder where you guys usually install it, i was thinking of putting it where the oilfilter is, anyone have any pictures of an installation?

 

I seem to remember something about oil coolers being an option on Gen III equipped trucks. My guess is that these simply use a different oil filter mounting pad that has provisions for the cooler line.
If I'm right, you could get that small part from a truck to bolt on and you'd have a threaded location to mount your sensor in.
I'm not very certain about this though.

 

I started to put it down near the oil filter at the fitting there, but did not like the clearance I had around my headers. I ended up using an adapter from Equus along with a right angle fitting and used the factory sender location behind the manifold. This is only feasible if you have clearance between the motor and firewall. The ECU does not get a signal from the oil pressure sender. Here is a picture of mine. With a taller nipple I could have turned it more toward the engine for additional clearance.

thanks to both of you, great info, and nice pic, my engine is installed and fired up, it sits a bit to close to the firewall to mount it there i think, so i guess ill drill and tap into the filter pad, i use stock manifolds on my car now, but if i want to use headers later i guess that might become a problem.

 

have a link to get the adapter cheap?
i'm planning on using the stock location, but adapt to a -4 braided stainless hose & mount the sensor on the firewall.

 

Ill try to do something similar to this then.

 

Hey all. I think this is my first post. Well besides my "wanted to buy" post that netted me an ls1. My name is Justin. Im gonig to be swapping it soon. Probably starting this week. I just wanted to ask Hersker Hans where that adapter is available if you know. Is that the truck oil cooler piece mentioned above?? That looks like the way to go. Nice and clean and hidden. Thanks!

Justin

 

that thing you see there is one all LS1s i think, im gonna drill into it with a
8.6mm drill bit, and juse a 1/8-27 npt (national pipe thread) tap and thread the oil sensor into it.

not sure where to get the adapter

 

Hans, I have some 45degree and 90degree ones with male/female 1/8" threads, we'll work something out

 

Isn't there an easier way to do this than having to drill and tap the block. What are you going to do about all the metal shavings? Why can't a T be put near the factory location to run both the PCM unit and the autometer?

 

Stealth, You do not have to tap the block, only the bolt on fitting. You can also put it in the factory location as shown in my picture above. The PCM does not get a signal from the oil pressure sender, it is only there for the gauge. So you would not need a T fitting. There is info in the FAQ on what fittings I used.

the piece they are tapping is held on with two bolts... it unbolts and uses a reusable sheetmetal/O-ring style gasket.

the factory actually drilled and tapped it on the trucks. in this case, it is drilled except for the last 1/4"... (to keep it sealed)
if you drill out the last little bit, you can tap it easily.. all this is done on a workbench.. or in my case, infront of the the TV in the living room..

 

Thanks. Well since I will have no LS1 gauge panel I guess I can just remove the original sender. Now I understand the part that can be tapped. I did some more reading. I have to see how much space I will have with the headers near the filter.

 

Great, looks like i might need a bend to place the pressure sensor where i want it.

btw im using the location by the oil filter since my engine is a bit close to the firewall, if i had more room there i would probably place the sensore there instead.

 

I haven't looked yet, but what do you guys do for water temperature?

 

Passenger side head, near the back. Adapters available from Equus. Check the FAQ for details

I just removed the plug, drilled and tap the the Head for the sensor. I used vacumn and grease on the drill and tap to collect the metal frags.. did it slowand a little at a time.

 

You should get the corvette version of that plate. It has a oil temp sensor tapped in. Or the HD truck version which runs a oil cooler from that point

 

It's a metric thread and the adaptor is an almost impossible to find piece.

 

If you look just below the cam on the throttle body, there is a flat, horizontal place on the water pump. Drill and tap that to 1/8 NPT and install the sensor there.

It will give you the temp of the water as it exits the block, a better, over-all engine temperature reading ...
