Looked for a long time to find a "Breil" oil cooler for my R100S engine on my sidecar tug. Finally found a supposed NOS one through the IBMWR site. Paid a premium for it. Received the new gaskets required and installed it today. Here is what I found: Oil was dripping before I even had the crankcase filled. Looks like each and every tube end was faulty when welded. apparantly the welds were over ground after completion. I noticed the exposed "rings" on the faces before installation but didn't give it a lot of concern...duh....Not all leaking yet, but when heated up she'll be running oil everywhere. So can something like this be Tig Welded? I If welded from the outside, it will look a little messy, but I don't care about that. I'm just afraid it will deform the alloy and distort it. Just want it to provide what cooling it can and hold oil. There isn't enough clearance on the insides to weld everything from there. The welding options are slim around here, but I'll take it to a couple shops to see if it is even possible to repair. The seller has offered to refund my money and take it back, which will likely happen, but I'd like to use it. Wonder if it is even worth trying to repair?
