    Default Oily Sensor Questions - ST185

    Hi peeps,

    Whilst recently dismantling my Intake System to clean out the oil sludge and put a in a PCV Oil Catch Can I found some sensors gunked up with oil.
    What I would like to know is does anybody know what they are, are my identifications correct?

    It’s an ST185, JDM 1993 GT4….
    You can see from the modified picture I took, underneath the removed Intercooler, in the middle, a collection of ‘oily’ sensors….

    Now then…
    Number 1. is my aftermarket SPA TEMP/BOOST gauge, the temp it reads is hooked up to measure OIL temp. At least this is what I think it is, it was fitted (not by me) some 6 years ago…
    Number 2. I’m probably correctly guessing is also OIL temp for the ECU I should imagine, am I correct..?
    Below Number 2. (not numbered) I think I remember seeing another sensor, although I’m not too sure, if you know what this one might be, please let me know….
    Numbers 3. & 4. Are they both Coolant temp sensors due to their location on the Coolant line?

    As well as the above questions, I was slightly concerned with the sludge around them, is this normal on Celis, where does it come from, and should I investigate further maybe to make sure nothing is leaking…?
    I’m guessing again, if I’ve correctly identified the OIL temp sensor that the oil must come from there, and maybe cleaning, then watching it again to see where it leaks from….

    This is the first time I’ve posted a pic, so if it doesn’t appear, please bear with me and refrain from replying to questions….

    Ta muchly,
    Frank.

    That oil build up looks pretty normal. You may wanna check your valve cover gasket It may be leaking a lil.

    Actually that oil build up look slike a good indication that your distributor is leaking oil. Problibly from the external o-ring and the internal seal. They leak internally the worst so you might want to remove the cap and see how much oil you have inside the dist.
