Posted 10/03/09 09:34 AM Share Posted 10/03/09 09:34 AM (edited) I scored a set F6 gauges for my car, and have to drill and tap a port for the boost sensor. Then, I checked the oil press. sensor and it looks like the same thread...... Does anybody know what thread they are?.....I thought they were 1/8 NPT but tried a plug to fit and no-go Edited 10/03/09 09:39 AM by BionicXR6T Link to comment Share on other sites More sharing options...

Male thread on the sensor and female in the hex adaptor to the block. The Male threads on the turbo oil screen hex fitting are 1/4 x 18 NPT on one end and M14 x 1.5p on the other end. Obviously the NPT goes into the block and the M14 goes into the hex adaptor which goes to the oil pressure sender unit. I put an extension between the hex adaptor and the oil pressure sender to tee off for my new gauge sender which has a 1/8 x 27 NPT male thread on the sender unit. Hope I didn't get too wordy and hope this helps. All the best with it. cheers. Link to comment Share on other sites More sharing options...

I just replaced the oil sensor on the sandwhich plate(for my guages) because it was melted. There was no thread tape on the old one so I didn't put any on the new one. Now its leaking a bit of oil. Is there a special type of thread tape or sealant that I use?Many Thanks Pete Link to comment Share on other sites More sharing options...
