I have two oil coolers that have been drilled out and tapped for the proper steel threads. The theads were installed using J-B weld as the sealer as well as the copper crush washer. The coolers was hydro flushed before the threads were installed to remove all old oil and debris. Have been pressure tested and repainted. Only have these two, so once they are gone, they are gone! A new cooler is about $335.00 and you still have the problem of the threads crapping out on you. These are ready to go and will last the life of your car! Price is only $150.00 plus shipping. Just email me if you want to get one. Also have many more Used W123 parts that can be found here.
