I just pulled the car out of the garage and found several quarts of oil on floor. Traced the leak down to the braided oil cooler lines. I checked local auto parts stores (no one carries new ones), and then checked local Mazda parts. They can order but are wanting $250 for inlet line & $275 for outlet line. Now I realize a sports car is no cheap toy, but I purchased this high mileage car, which runs excellent for $500. My question is: Are there any alternatives to the factory style lines? I'm not trying to just rig something, and I don't want to cheapen the vehicle, I just have a hard time paying over $500 for what should be two simple oil lines. P.S. I talked to local NAPA store about reusing ends to existing lines and crimping new hoses (like hydraulic lines). They said No Go.

 

here's what came up searching google. ever try it?

or

both are less than $250, and some would argue better quality.

 

no its not.

 

I take mine down to a local shop that makes hydraulic lines. If I cut and remove the ferrules and show them how I need the ends clocked, it costs me about 30 bucks for both lines.

Check out this link on how to do the lines.

yup

 

Or you can get some AN fittings and stainless line, and follow the instructions in the 2nd gen archives to make your own for about $150.

 

rxtasy3: those lines look pretty cool, I'll check into those later. 3vil: the previous owner put me onto mazdatrix (there's look good, but they want +$200). trochoid: I cut the ferrals off and took the hoses to the local NAPA, his crimp fittings won't adapt to the original banjo fittings. There are a couple of industrial hose repair shops in downtown Atlanta, and I will call them today. As for the AN fittings, I need to find a way of id'ng the metric sizes, as most of the local shops who carry them only carry standard measure fittings. I appreciate all the help and suggestions. I rarely post, and its nice to receive so much good information.

 

You'll find the fittings needed for AN listed in the 2nd Gen Archive forum. Any hydraulic shop will have the metric fittings you need.

 

The answer depends on your time-frame for owning the car. I have had my FC for 12 years. I first changed the lines to some I found in the junkyard. Those lasted 1-2 years before new leaks. Then, I took the old ones to two different hydraulic shops after spending a lot of time saving the old ferrules, and neither could do them. Then, I bought the aftermarket mazdatrix ones, and they have lasted so far. They where over $200, plus mazdatrix is not cheap with shipping. I looked at making my own AN fittings hoses, but it just wasn't enough savings to make sense.

 

76rx7: I have found the same issues. I removed the factory ferrals and took it took an industrial hydraulic hose maker that the company I work for uses and they wanted to send them out to an old boy to weld to so they could adapt them. I am trying to decide between ordering my own AN fittings & hose (kind of nice to say I put that together), or ordering Mazdatrix hoses.

I want to thank everyone again for their input.
