Anyone replaced Oil Pressure Sendier (Guage) on 993?
My 98 Cab's oil pressure guage just pegged to 5 and stayed the other night. It occasionally jumps back to a reading and then pegs to 5 again. I assumed the sending unit is going out and ordered new.
I have a manual and parts breakdown and know where it is. Removed the airbox and can see it behind and just under the intake. However, just how do I get to it to remove it? Any assistance would be greatly appreciated! Cheers! |

If you can get your hands on the sender, you are in luck
Go to sears, and buy a stubby 15/16ths (a.k.a. 24mm) wrench That is what will break it loose. They aren't torqued on all that tight - 25 - 30 ftlbs. AFJ

Removed the airbox A tech friend (local Porsche NA) came over and suggested that it may be that the connection was grounding. we moved the wires a bit and checked that the connections were tight and when fired her up it was still reading a bit high 4+. He said the pressure should drop when it gets warm but I dont remeber it ever sitting that high at idle. However, once she warmed up I went back to the guage and it was pegged at 5 again.
I guess the sender is shot? Odd, have these cars over 30 years old and no such issue before. I did see the nut portion of the sender with a mirror from the back but the secondary air pump motor seems to be in the way of really getting a hand on it. Porsche suggests that the right side intake manifold will have to come out. I really dont want to crack into a perfect engine! From what area should I try a stubby? The rear? Should I or can I try to remove the air pump(under the intake)? Thank you for the reply!

You can usually find one or two angles where you can get a wrench on it.
Another option is a 3/8th inch drive, 15/16ths crowfoot on an extension. AFJ

Yes, I had thought about that actually - lying in bed (sleepless cab owner LOL) Going to try just that. Thing is, if I get it out can I get the other back in?
