I have a triple gauge kit I need to install on my car. Where is the best place on the engine to hook up the temp and oil?
I have a "rebuilt" engine and trans I bought for $600. and looking at installing gauges on it so while the engine is out, I figure it is the best time to put in the sending units. Pics would be ideal too!

The temp sender is best installed behind the stat housing just off centre.You will have to drill and tap.The intake is thin at that spot and easy to drill and tap.The oil sender can be installed in the side of the block.Just back from the existing sender on the left side are 2-3 pipe plugs parallel to the existing sender.These are also oil passages.If you can get a plug out you can use that to install the sender.I just removed the existing light sender and used that place for the aftermarket one.The pic shows where I installed my temp sender if you look close just under the aircleaner beside the heater hose fitting..

Thanks. I like it. How many threads are on that temp sending unit? Obviously it doesn't leak, but you say thin and that is one thread to me. Just curious.
For the oil, I will try to keep the light just in case? maybe a fail safe?

Will the temp sender fit in the original location, rear of left head? I think it's good to keep the lights also. They will catch your eye quicker.

It will allow for multiple threads.The aftermarket units come with an adapter that screws in first and than your sender screws into the adapter.I just meant its thin enough to drill easily with a good quality steel bit.I actually had mine done by a machine shop for $20.00 before I installed it as I purchased a "B" manifold.If you unscrew the heater hose adapter you can see the thickness. If you look at the right side head you can see where the temp sender would go if the head was used on the left side(heads are identical).That plug can be removed and an adapter installed.The Ford original adapter is a press fit.The consensus from several members is the area behind the stat housing gives a very accurate temp reading.

As far as the oil sender is concerned, if you cannot get one of the plugs mentioned out, get a short nipple the same size as the hole for the stock sender, a "T" fitting to fit the nipple and you can screw the old sender into one hole, the new sender into the other hole. You may need a reducer for the new sender.
If you want to keep the "T" closer to the block, get a right angle fitting to put on the nipple.

Paul, Are you talking a street ell?
Mark, I do know a machinist! I have to order some gaskets anyway. Might as well be a manifold one too

+1 on "behind the thermostat" location, which is highest coolant temp. Stock sender location at back of the head measures temp of coolant just entering the head from the block, so it's actually lower than the temp of water at the thermostat. Before I had a heater, I used the upper heater hose hole for the temp sender, and it worked well.
Once I had the heater hooked up, I was cheap and installed the sensor in a tee fitting inserted into the coolant recirc hose, thinking that it draws from the same place and would be the same temp. Not so... it seems to run 10-20 degrees cooler than behind the thermostat/heater upper hose location. I measured/confirmed with IR thermometer. I'm not sure why, but it's consistent... maybe getting back-flow from the water pump? Another indicator of poor water pump design?

Here's a pic of my recirc line setup, which I can't really recommend.

Thanks! Good to know. I will order a new manifold gasket along with my valve cover gaskets, and get that drilled and tapped!

I have a suggestion while you have it apart.You might consider blocking or restricting the heat passage crossover from head to head through the intake.Keeps the heat off the carb for summer driving.As long as you either remove the heatriser or wire it so it stays open.You can use a couple of pieces of tin or aluminium to cover the openings in the heads before you drop the gaskets in place.They also sell a restricted gasket set which leaves a small opening for heat to crossover.

A street elbow is a 90 bend. It has male threads on one end and female on the other.

Like Royce says, Keep the idiot lights as well, I have heard and know of many stories when people were driving home late at night and not watching their guages and lost their motor. the idiot lights get your attention and they have saved me motors before where without them I would have been like the others and probably lost a motor from not paying attention to the guages, but when a red light comes on you wake up even if you are driving in your sleep, they are fool proof! Dont disregaurd them!

To clarify, the restricted intake gaskets that Old Car Mark refers to, are originally a truck item. The heat opening is about 1/4 the size of a standard gasket opening. If you can't find them at you local parts store, the're available by mail from Gasket City Hamilton Ontario Canada. www.gasketcity.com or Al @ 905-679-6597. He has extensive stock of vintage gaskets & seals. Also places Ads in Hemmings. Prices seem quite reasonable. (I'm not associated with the company)

If you have never used a pipe tap take your time. Make sure it is perpendicular to the place in the manifold where you have drilled the hole. Some taps have a centering hole in the back and if you can set the whole thing up in a drill press with a punch in the chuck and have some one keep a slight steady pressure to start it straight as you start turning in the tap. Take it slow as a pipe tap is tappered and if you go too far you can't put the treads back in. Back out every so often and try the fitting so you know where you are with the fit. Use a lubicant, I like "rapid tap" for doing this kind of a job.
I personally do not like teflon tape for a sealant just because of its looks and use Permatex #2 or the equivalant just a personal choice. If the line has an adapter remember to hold it with a wrench when you tighten the gauge line into it.
Most of this is common practice but when I'm drilling a hole in something a don't to screw up; I talk out every step first and set out everything I'm going to need. I agree with doing it right behind the thermostat; I carry a IR gun in my glove compartment and that's the hottest stop I have found...............Good luck

Would it be possible for someone to post a pick of the oil pressure sending unit installed. My block was rebuilt and the builder plugged all the holes in the block on the oil pump side of my 292.
There are three locations with female hex pipe plugs front middle and last behind the oil filter, which would be a real pain to plumb, and two square pipe plugs under the forward freeze plug. I am going to use the gage in the speedo head but after reading this post I may tee it off and mount an idiot light as well. I tried removing the middle plug but it just strips out the plug.
Thanks
John

Any of the threaded oil holes in the oil filter side of the block will be suitable for an oil pressure gauge line or sending unit to be hooked up to. On some blocks, there are five potential locations. Here’s a picture of a block that has four potential locations.

Ted,
Once again you have my answer, Thanks for all you do.

That is nice. Thanks Ted!!
Also, I was thinking......... The Heater hose hookup, right behind the thermostat, can I replace that with a tee? and bushing out one side then go to the heater hose on the other? My heater is not hooked up. So it is just a loop for the hose.

If you want an accurate temp reading the sender should be immersed inside the manifold.If you have the manifold off its very simple to drill and tap.

That is fine. I have no problem drilling it. My gaskets just came from rock auto. I thought since it was right there, it would have been easier

Are you going to block or restrict the heat crossover passage while you have the intake off?
|
By sprink88 - 12 Years Ago

I was thinking about it. It is not the gaskets I ordered. But mentioned I could use a piece of metal? I would rather just use the gasket. I may order it. Not working on it to much now, as we are expecting, ugh. more snow. Like plowable snow. grr.
