Hi All,
I have a question about the modifications done to the engine mounted oil cooler when a 3.2l is mounted in a 914. Rich Johnson posted an excelent picture of the modification in a recent post and I include it here. My 3.2l cooler was already modified when I got the engine. Now I want to chanfge the routing of the oil line where it connects to the cooler, because it interferes with taking the valve cover off. The oil line is a stainless braided one with Earl's AN type fittings on the end. When Rich says AN or metric threads for the conversion, is there a type of oilline that wants metric threads used in this situation, or do AN fittings have metric threads? How can I figure out what thread I need so I can buy or have fabricated a short extender for the oil cooler output? - 914-6 style oil cooler modification (metric or AN) thanks Mark Attached image(s) |

The photo you've posted is a 911 oil cooler that was modified to use Porsche style oil lines, which are for the most part unique to Porsches. If this is how your oil cooler looks, my bet is it's got the Porsche style fittings on it.
AN fittings are commonly used on conversion cars, but the cooler is usually modified differently. If you have braided stainless oil lines, then you've probably got an adapter somewhere. I say probably because there have been some hose fittings made for Porsche oil fittings, but they are very rare. The difference is the threads on the Porsche fittings are 1.5 threads per millimeter with a concave seat or sealing area on the fitting and convex on the hose end. The AN fittings are coarser threads, I don't know the exact pitch, but more like the 3/4" NPT. Also the seat or sealing area on the AN fittings are convex on the fitting can concave on the hose end, and the threads to join the Don't know if I answered your question or not, hope so.
