This is my kind of thread.

Like many folks my car developed a sudden oil leak which I at first thought was the oil temperature sender and Pete made two good repair procedure suggestions - remove the passenger wheel and the center section of the wheel well liner. But once I removed the wheel and the wheel liner section and started to clean up the sprayed oil it was clear the cause was the oil pressure switch rather than the sender and searching the forum I found folks divided on whether the better approach to replace the switch was to remove the oil filter adapter or to raise the passenger side of the engine. Then I read Dave's procedure.

I have to admit I've done some unusual things in caring for my cars (and trucks and motorcycles) over the years but lying on them is a new one. Still it did make sense to help get one's left hand in a more natural and useful position, although removing the wheel goes a long way toward that same goal (of course all this assumes small hands as without removing hoses the space is limited). And I was already using a variant of Dave's stainless steel wire suggestion. But what really helped was seeing the picture of Dave's tools and particularly his flex head 3/8" socket driver. As the saying goes "use the right tool for the job" and indeed the flex head made all the difference in the world.

Unlike Dave I didn't yet have my replacement switch so I couldn't quickly button it up and total my time spent. Plus having removed the wheel and center section of the wheel well liner and done a lot of cleaning my time on the clock was much longer than his. But the important thing is result. And I now know that even if my new switch fails sometime down the road replacing it by removing the passenger wheel and the center section of the wheel well liner, using a helper wire to support the heavy socket with a flex head 3/8" socket driver is a doable task. So thank you, Dave.

Thank you so much John. I'm so glad it was helpful.

My pressure switch is leaking so search lead me here. Is there any sealant or Teflon tape used on this switch? Looks like switch may have something applied to threads on replacement part. Also wondering since my hands are larger than space allowed in most engine bays and this looks particularly tight, what size plugs are required for the oil lines?
Thanks much very helpful information, got my moving blanket ready, just waiting on the part. Thanks,
Tod

Tod, I'd refer you to my post #10 above for additional suggestions BUT will add that the limited space makes this is a hard job even with small hands so you may want to try to enlist a friend with small hands to help. The flex socket in Dave's pictures is indispensable and keeps one from having to disconnect the oil lines. I did not use Teflon tape but if you do use the "yellow" gas/oil resistant tape. John

So prob dumb question, new to pressure switches, but is in a special socket or just a large deep 6 point? And is it wrong to wish I had smaller hands for this procedure? LOL If I were to pull the oil filter riser off, are there multiple gaskets that would need replaced(hope I wont have to).

Thanks John

Not a dumb question at all. They make a special socket for it but a medium length 6 point works just fine.

Hey Dave,

Would you happen to know the part number to the one on the top by the oil filter? When driving this weekend I noticed at idle my need on the gauge is bouncing a little bit. It is fine when accelerating or driving otherwise and my guess is the sender is bad. The diagram indicates the one for the gauge is the one that is upright by the filter.

Thanks,

Craig
