Topic: Time for New Oil Lines ?

[rddcw]

Has anyone used the oil lines before ?  I changed out the oil-rings on both my supply and return lines for my 74' CB 750 K4, but still has a slight oil leak. Under closer examination, it appears to be coming the compression fitting  ( supply line ) at the end which bolts up to the engine? These lines are complete and looks likes the vender uses the stock ends but different compression fittings. Priced at $120.00. Guarantees his lines not to leak and compression tested to 100 p.s.i.

Any recommendations you Tech guys may have. I probably could buy re-cut oil lines and clamps and make my own

O-ring on motor side and alu washer in the oil tank fitting?

Changed Both O-rings on the motor side. Might be the opposite end of the oil ones? I felt for oil leaks at those ends but couldn't see or feel anything rubbing my finger around the fittings?

if they leak at the fitting, send them back. 
obviously NOT tested to 100psi 
test his 100% guarantee

The oil lines that I have on the bike now are still the original ones. I was considering purchasing the one's I pictured above. Just wanted to know if anyone had tried these?  Or if some other members are using something different?

Looks like the oil drip is coming from the compression fitting at the end of the supply hose right where the hose end at he engine side goes into it. At least that's where the only drip is at. Opposite end of the hose at the oil tank is dry.

Looks like New Lines.

The hose itself could be leaking through tiny cracks in the rubber which you can't see because of the cottonlike covering. The oil wicks its way to the fitting so that it looks as though the fitting is leaking. If they're old replace them and remove all doubt.

Krusty,  I know your right. That's why I posted a picture of lines that a vender on ebay was selling. Didn't seem to be too badly priced unless there are other options that some other forum members have used?

It must be serious hole if they are leaking, these hoses carry about zero psi pressure; one is a supply line and other is used to pump oil into vented tank.

People made their own using hydraulic hoses and ferrulas with original fittings. There is a bit of trouble with crimping, seems like these hoses are odd diameter to have crimped in pro shop but it was done.

I made two sets for two different bikes myself and they all hold oil well.

The O-rings changed out did slow done the leak considerably, but still getting a few drops of oil under the bike and around that oil line.

Has anyone used Oil Lines that Carpy's Cafe racers sell? Besides making your own, anyone else purchase these lines from another source?

I bought a couple of sets from Cycle X.

I have only installed one set and have not leaks and no problems with them.

I had one start leaking at the compression fitting and after cutting the fitting myself, I took them to a shop that sells those parts and they gave me a stainless braided line and clamped them down with new compression fittings for like $20.
