There is a fitting on the lower right on the block, near the back of the driver's side, just above the oil pan.
Oil Gauge Connection Just So ; It is the same fitting used when you add an oil filter so if you go look at any of the numerous oil filter threads , you'll find very good pictures of exactly where you need to connect it . Remember : use steel tubing as copper will fatigue and break in due time . When my original steel oil pressure tube rusted away after 50 yesrs (NOTE TO SELF : write GM and complain about poor quality raw materials) , I got some stainless steel tubing and used that .
What fits there? Hello Nate, hello chebby, my truck have a seperat oil filter box that sits on the inner fender. On the first photo you see the two fittings for the oil tubes to the motor. There are other holes which I can't remember what they are for. If you could help it will pleasant. Wolfgang
One more photo from the motor On photo you see the oil box there is in the red circle a cut tube could it be the connection to the oil gauge or what was it for? Asks Wolfgang
Wolfgang, in the first pic, the 2 fittings are for your oil filter hoses. The fitting in the back (closest to the firewall) is where your oil pressure line going to your gauge would tie in. When using an oil filter, you'll have to install a "tee" fitting so that you can connect the filter hose and oil pressure line. In the second pic, that is a petcock, or drainage plug to drain water/coolant out of the engine block. The third pic is where the oil distributor would be mounted to the engine if you had the old "dipper" engine (216 and some 235's). If your engine is a full pressure 235, no oil distributor is needed. I know that 235's '54 and newer were full pressure. Not sure on any 235 prior to '54. Sorry I'm no help on your pic in your other post. My eyes aren't as good as they used to be!
The hole in photo no.2 Hello Ken, the hole in pic two is a water drain. The oil pressure tube seems going from the oil filter box to the gauge. I'll send a photo in a seperat threat. Wolfgang
Here is a photo from the oil pressure tube on the filter box Here is the photo. Who has a similar tube? Wolfgang
After looking at the picture again that shows the oil canister, it appears as though whoever installed it decided to put the "tee" fitting on the inlet to the oil canister and run the oil pressure line to it instead of putting a "tee" fitting on the block where the oil pressure line originally went. I guess that would work, but I'm wondering if the oil having to leave the block and travel through the hose before it gets to the oil pressure line would affect the accuracy of the measurement (not that they are that accurate anyway) Here's a link to a tech article on Keith Hardy's website that has some very good info on installing oil canisters. http://chevy.oldcarmanualproject.com/miscellaneous/oilcanister.htm Hope this helps.

Thats want I wanted Hello Ken, thats what I wanted, perfect with photos! Thanks for your help Wolfgang
Steel instead of using brassfittings the Oil filterline to cannister Hey Nate I read that you recommend to use steel tubings instead of the copper oil pressure tube.Where can i get these in the store in USA ? Martinius.
Pictures Pic # 1 is the oil filter return line connection Pic # 2 is the water jacket drain , if coolant doesn't come out when you open it , remove it and fish in the hold with an old bit of welding rod until it does ~ *very* important . Pic # 3 shows you have a '55 235 , those three holes are for the side typ motor mounts , just ignore them . FWIW , you appear to have the standard accessory by-pass typ of oil filter , some one prolly lost the original mounting hardware , no worries . it should take the 5" oil filter , look in older posts about oil filters for the correct part #'s and color schemes to paint it .
Mystery Tube LOL ! that's a left over bit from the original 216 engine , amazingly the oil pipe for the top end passed right through the cylinder block between two cylinders and had a special pipe and fittings ..... God alone knows why they saved this , it's useless .
Oil Gauge Tubing Well ; I just ordered it from my commercial brake supplier . I wrote a post about it some years ago so go look at my posts and you'll find what you need to know . I know that's a vague answer and I apologize but I cannot keep every detail in my old grey head , I know you use all the same brass fittings , just use steel or stainless steel tubing , what size was it ? maybe 3/16" ? . I forget but I know I posted it .
Realize this is an old thread .... oil line To confirm- -the yellow line points to where one connections the oil pressure gauge? -the green one is where one would connect to the drain of the external oil filter? If anyone has the specs on the fitting that goes into the engine block, that would be really appreciated. Thanks, Haasman
I believe gauge tubing is 1/8". We get our steel tubing from WW Grainger which runs $10 for a 6ft piece. I'm sure others have it cheaper but there is a Grainger store right next to where I buy gas so it's handy.
Yep got the tubing. Wanting to know the connection point on the engine and if someone can provide the fitting size. Haasman
