Very impressed. Rivnut with the OEM M8 threads. Had to ream the hole out a bit and its a nice snug fit. I'll pick up a pair of new bolts tomorrow so they use the same tool and I just need to collect my repaired oil cooler on Monday and reinstall.
Taking forever to get the repair done. They're taking it all apart because they can't put the hoses in their crimping machine with the oil cooler attached. They heat cycled the nut on one side a half dozen times before it came loose and apparently that was the easy side. Heat cycled the other one a bunch and this last time they heated it up and then submerged the nut in oil and left it to cool off.
I just called the shop this morning in regards to my oil cooler and when the old guy answered, all I said was: “oil cooler”. A short pause later 😂 the guy said a bunch of stuff then said to call him back later about it. Then I didn’t call later. Maybe I’ll just show up tomorrow to see if he’s made any progress whatsoever other than crush every single little loop on the cooler then I can just call it an oil tube that literally has no cooling capability whatsoever.
Well they finally called this morning. The nut finally came loose, unfortunately it also cracked as it came loose, see photos.
They didn't charge me anything, offered some suggestions such as just getting a comparable length universal oil cooler and they can get it all put back together with standard sized fittings and nuts.
Anyone else gone down this route? Alternatively if i can source the right size aluminum nut and clean up the threads on the cooler side, they can probably repair what i have. Anyone know a source for the nuts or use an aftermarket cooler?
@nilanium sent you a PM the other day. Wondering about your spare oil cooler and/or any bits you may have that I might use to get my car back on the road. If you have anything left, can you please PM me?
Got my replacement oil cooler assembly from Nilanium Saturday, installed last night, filled her up with oil and fired it up. Not a drop or seep evident. I'll do some local driving to make sure before I go back to using it as my daily, but it felt great to get back in the car as its been waiting for me in the garage since mid February.
I would be curious to know what caused the lines to start leaking in the
first place.
I know I've had a few similarly constructed lines fail on motorbikes. There it's always been the inner part of the crimp that presses onto the hard line fractures or rots away so the flexible hose is no longer securely attached.
If anybody happens to know what size and pitch the threads are on the engine oil cooler, I would be much appreciated.
I found that it’s a 28mm x 1.5 pitch. I went to our local Grainger and no fittings in that size existed there under plumbing, hydraulics or automotive. I have a 4500 page catalog from McMaster-Carr that I’ll look into. If it’s not in there, it doesn’t exist.
Well…. I’m entertaining the idea of looking into a modern universal external EOC. I need to take measurements but, trying to find the right one is going to be a challenge. Ideally I’d want one that oil fittings will enter and exit from the sides (think 9 & 3 o’clock position) like the original one but, typically they’re in and out from the topside and I’m not wanting to cut the bumper and/or bumper cover to make it work. When I went to the shop where it’s at, we talked about it for awhile. He tried calling this big A/C supply company out in Texas that may be able to help with fittings but, I’m not holding my breath that they’ll have anything. I could snag the oem EOC off of my daughter’s car but, the hoses are way older and over double the mileage as mine was. She drives that car like an old lady so I’m not concerned with oil temps on that car with the EOC bypass in place. The bypass is currently on my car btw.
