i just recently bought the mazdatrix stainless oil lines for my FC and i was wondering when i go to install them should i use like locktite or PTFE tape to make the seal better or just screw them/bolt them right in? thanks guys

 

Oil cooler lines or Oil Metering system lines? Either way you need new brass crush washers to insure a tight seal. You can reuse the old ones on there currently but it WILL leak oil. Not to the point were you will lose oil pressure and dump oil everywhere, it will just be a nagging oil leak that will leave oil spots everywhere you park.

 

ah okay. ill try to find some locally. thanks

 

I would just go straight to a Mazda dealer and get OEM ones. It might be slightly more expensive but it will insure you get exactly what you need. Also we are talking about washers here so it's not like you are dropping $100 or anything.

 

the stock copper ones can be re used. you just have to anneal them.

hit them with a blow torch till they get red hot, and scrub the carbon off of them, and then you can re apply them.

 

I got new ones at the Mazda dealer for under a buck a piece. Seems like your time is worth more than that.

 

shouldnt they have come with new crush washers in the first place?

 

It was a long time ago, but I believe my kit came with new crush washers...

 

got the oil lines on. came with new crush washers. thanks guys

 

I wouldn't worry about not having OEM lines. I've never heard of Mazdatrix or Racing Beat lines failing, probably thanks to the AN fittings. I've heard of other brands failing after a year though. Who knows how long the AN lines last, but they last at least as long as they've been for sale. We only know OEM lines fail after around 20 years because we've had them so long.
