I found I have a leak in my oil cooler hose near where it bolts into the front cover. It's not a leak at the front cover and crush washer but about an inch back from that, where the braided steel is capped and meets the screw. The whole screw on the end moves in and out of the hose a bit and can wiggle side to side, unlike the other end that doesn't leak. Is there an O ring or something inside there that could be bad? Any way to repair this leak or do I just need new lines?

It's a GSL-SE by the way. I'm pointing to the location of the leak in the picture below

 

replace it ....

 

not factory hose. however it is crimped on the factory hardware, so you could take it to a hydraulic shop and maybe get it fixed (there are no shops where i live, they all went belly up and turned into crossfit gyms, and this is before the lockdown, and not just hydraulic shops, but every shop)

 

If it's not something I can fix myself I'll probably just order new lines. I just wanted to check before spending another $200 on stuff if I can help it.

I'll probably get the Banzai hoses since they're cheaper than Racing Beat's including the adapters, unless there is a good alternative or a good reason why the Racing Beat ones are better

 

I think both are overpriced. I bought specific adapters from Racing Beat to adapt oil cooler to AN type lines and bought AN fittings and line from Jegs and made my own lines.

I used heater insulation on hoses to replicate the foam used on oe lines to prevent chafing
I replaced the foam seal on bottom of radiator while making lines using air conditioner seal foam and held it in place on radiator with 3M side molding tape. The foam on my radiator had previously been in good shape but stuck to undertray when removed to effect oil cooler line replacement.

OP,i still have my OE cooler lines from my SE and you are welcome to them for postage to ship to you. They do not leak,i wanted to renew them before they became an issue. I had a leak on bung at cooler and decided to go the AN route and cut off the cracked area on bung and welded on Earl's AN fittings.

 

I have a AN tool like this from Koul. It's a must when putting these together alone with have a good -10AN wrench and a 1 1/16" wrench.

 

Thanks everyone and especially for the offer to ship your OEM lines! I’ve spent a lot of time and money restoring my FB and I don’t want to cut corners with used hoses though, so I went ahead and ordered the Banzai set.

Ordinarily I’d make my own but I’ve got like 4 different issues I’m simultaneously trying to sort out to get this car running and this is an easy way to check one off and move on
