Hey guys, I tried searching for a similar thread but I figure its probably not an issue someone with basic mechanical skills would have. Im new to vehicle maintenance ect. Im a newb with no skills. I just bought a FC3C this week and I heard an alarm when I would get to 5k rpm. I looked through the forum and came up with either low coolant or low oil. I filled up on both but as I was draining and refilling my radiator I noticed an oil leak from a line that looks like its going from the motor to the radiator? Once again I have no idea what Im looking at... Thanks for any help!
Some pics to help identify:

2. top view from left wheel
3. under the car, facing left wheel
4. again underneath, facing left wheel
5. under facing the motor, left wheel behind

 

Those are your oil cooler hoses. They are usually quite resilient but can go bad, mine blew at 100K

Either source yourself a pair from the classifieds (cheapest) or many vendors (corksport, banzai, mazdatrix) offer new stainless steel replacement (more expensive, but better insurence)

 

Cool thanks for the info! Seems like a pretty basic problem and solution, Im kind of embarrassed lol

 

Everyone's gotta learn somehow!

 

What does -AN and -10AN mean? If I was to do it myself what tools would I need to complete? I have access to a shop with most tools and lifts. Also I have a koyo radiator installed, are these kits easily compatible?
Oil Cooling (86-91 RX-7)
Cart Price Check Part:PT11910

 

AN is Army Navy standard. Its a specific style of high quality tube fitting in this application.

Looks like the Banzai kit adapts to the stock thread pitch so it's an all inclusive kit. But if you saw the note "NOTE: Installation of this kit requires relocation of A/C lines if applicable. " and it applies to you, it might be a pain to setup. May want to look into that more if necessary.

 

I guess in this case it's a good thing the A/C doesn't work anyway haha

 

Getting to drive it more now, Im noticing its burning through coolant pretty quick along with the oil leak. Its definitely looks like oil is dripping from the line, is it possible the oil is leaking into the radiator coolant and both oil and coolant are leaking through the hose? Or is the oil leak reducing the amount of oil in the engine increasing the temp of the oil causing the coolant to evaporate?

 

Really Im asking if I should just replace the whole coolant system or just take it one step at a time and start with the lines?

 

The oil cooling and engine cooling system are completely seperate, they are by no means meant to combine on any car

If your going through antifreeze and don't have white smoke coming out've the exhaust (car warmed up) than start looking for leaks, if you can't find a leak, look at your heater core

FYI, the heater core line that goes from the rear iron to the core is prone to going bad

 

I have basically no knowledge on motors lol but theres no smoke, the only leak I noticed when I had it on a lift was the lines pictured above. Car does backfire and spit fire A LOT.

 

Ive ordered the hoses, when installing is there anything I should do like draining the oil before I take remove the old hoses?
