Hey guys, I've had a pretty big oil leak pooling in the valley between the heads. I tracked it down to the oil temp sender. I pulled off my old one and it looked pretty tired, with a pretty bad washer. This is the part I removed: Image Unavailable, Please Login Looking to order a replacement, I'm getting some weird parts cross-referencing issues. FPE is showing the two different senders: 100453: Image Unavailable, Please Login or 30816210: Image Unavailable, Please Login Is 100453 the correct replacement part? Is there a crush washer or some other way handle the oil leak? Thanks!!
That looks like the low oil pressure warning light switch 110664 (if you have 1978 US version 308 GTB/GTS). See #37 here: https://www.ferrariparts.co.uk/diagram/ferrari/308-gtb-gts-usa/019-lubrication-system to compare the location that you removed it from (the oil temp sensor is down in the wet sump). https://www.ferrariparts.co.uk/part/ferrari/110664 (But you might need to supply your own Copper or Aluminum sealing washer as your old one looks like it came with a captive Aluminum sealing washer.)
Hi, when mine broke down, short circuit, I found a local Alfa dealer who had a similar with correct threads. It uses a crush washer, just anneal the old one or buy a new and you are good to go. I usually sand down a bit with 400 grit paper (EU norm). Maybe not necessary, but I have found washers with deep scratches. These are easily seen when sanding a bit.
@Steve Magnusson That's got to be it! Thank you for pointing me in the right direction!! Will a simple, copper crush washer get it done??
Yes, a W60 solid (annealed) Copper washer with the correct ID, OD, and thickness (probably 1.5mm) willl be fine.
