Hi all, my 997 has 30k miles on it. Over the past week, my oil temp gauge has been very slow to climb to normal operating temps. Once there it will hold for a bit, and then randomly drop down to 150° or even below. Oil level is spot on. I know that my problem is sensor related and should be a simple fix. Anyone else experience this? Pic for the help.

the pressure sender is easy - top of passenger bank - but the temp sender is difficult to get to, i believe. it's #27 in the diagram below but i guess my dumba** honestly can't tell if that entire assembly is internal (bitch to get to) or external (not that bad).

Thank you for the response!

Just to add I can confirm that the oil gauge does fluctuate a bit - even with a new sender it can do what you describe.
