Hi everyone, Question can I use steel brake lines as replacement of the rubber oil lines? Currently I have 53 sedan 235 engine, which came with modified stock exhaust for split manifold. I have replaced the oil lines but they seem to be close to the exhaust. I have fear while driving may make contact. I have wrapped the exhaust with heat wrap. Was just looking for a another safety preventive measure. I do still have the old oil filter canister attached to the manifold. Game plan for the steel brake lines to run them near the block towards the alternator, up into oil canister.
That's what I've done for over 50 years with no problems. I would think a hydraulic brake system has a lot more pressure in it than an engine makes. Anyone know for sure?
The only concern I'd have is if the oil filter mount flexes/vibrates any, possible cracking the lines. Putting a 'loop' in the lines should address that.
^^you make a good point. When I did this I tried to make sure there was pretty good flex in the steel lines; bottom line quite long with a bend and the side has some bends as well. So far - six years on the road however, I will put this on the to do list. Thank you!
Bringing up old thread So my 235 is a Babbitt pounder, Idk if it’ll cause the problem. I have upgraded to steel brake line inner diameter looks like 3/16”. I have low oil pressure, no leaks have been found. The original lines I removed are from National Chevy ***ociation. When I put back old lines back on pressure builds back up. On idle, my old lines I’m at 30-35 psi. With the steel brakes lines down to 15-20
There is a very small orifice in one of the fittings on the inlet, It is something like .060" without that small fitting the pressure will be very low. Look close at all the fittings on the inlet side
