Banjo fitting on the back of the engine

Last week during a four hr race, the
Banjo fitting for the vent hose on the back of the engine decided to back out and I lost all of the oil resulting in a siezed engine. The software for the engine does not recognize a drop in oil pressure so it does not alert you to the problem. I was doing pretty well in the race untill I came to a sudden stop. I would recommend some sort of safety wire on it to prevent it from happening to you. Luckily I only spun a bearing and didn't do much damage to anything else, but it could have been really expensive.

The one at the back and very bottom of the engine. Just in front of the tranny mount.

Re: Banjo fitting on the back of the engine

I'm with you...........in that I HATE that fitting. You can never be sure you got it tight enough to keep from backing out because you don't want to ruin the aluminum threads. So it's always unsettling with that one. Safety wire is a good idea. Do you have a way to drill the bolt head for safety wire? I want to say that bolt is a unique, hollow design. so you can't go buy a standard bolt with holes for safety wire. It's gonna need to be drilled with the one from the rig.

Re: Banjo fitting on the back of the engine

What I don't understand is why they put a banjo fitting on the breather line, but only a hose clamp on the two main oil lines. I would feel better if you could put a fitting on those ends. Then you could run braided line and not worry so much about rubbing a hole in one.

Re: Banjo fitting on the back of the engine

You can! It is 10mmX1 thread but 1/8 pipe thread screws in and seals perfectly. The hole on both ends of the cylinder head is the same 10mmx1 and you can screw a oil pressure sending unit into either one of those for a oil pressure gauge that will tell you the oil pressure. The holes in the head are for the oil supply line on the turbo motors.

Re: Banjo fitting on the back of the engine

I was talking about the breather line at the back of the engine. The oil lines from the oil cooler and the oil tank can be replaced with 12AN steel braid hose and fittings. You just have to use hose clamps on the engine and the oil tank. The oil cooler is 1/2" pipe thread so you put AN fittings on it. Looks cool and makes oil changes easier too. We have done it on 3 of our cars with no more leaks. We also strip all the black paint off the oil coolers for a custom look.
