The oil filter bracket on the Driver doesn't have a holes for the oild temp sensor, you'll need to find somewhere else to mount one. I've heard that you can get a replacement sump nut and mount one there, but sounds like a bodge to me!
I'm going down the scrappers at the weekend to grab a filter housing and sender off a GTI, fits nicely on the 1.6! If you manage to find a 16v they have 2 senders so you can do both pressure and temp!
