    Icon10 Peugeot 605 Guessing Game: "What Drip is That?"

    Actual source and fluid will be announced Sunday.

    Under the front, a whitish "smoke" emanates at times.
    There is a hot smell.
    Drips can be seen forming towards the sump plug.
    All fluid levels are within tolerance.
    Performance seems normal.
    Water and oil temperatures indicate normal.
    Everything except aircon works.

    I call coolant.

    By the way, the information that drips form at sump plug is useless. Of course drips are going to form there, it's the lowest point! Din' matter what it is, if it can work its way down (which fluids have a bad habit of doing), that's where it'll end up.

    Where does it originate - that's the million dollar question.

    I'm still waiting on a callback from Neville W. Caillé...

    Have got one leg well in the air with a stand under it, can report PAS is bone dry. Suspected trans output seal barely damp (relieved, if it had been that it would have shaken my confidence in replacing seals when core shaft is a bit marginal).

    It's almost certainly motor oil. There's no oil in the water, and no water in the oil. Coolant weeps/drips are evident elsewhere. Front main is bone dry, you could not ask for better. Oil/water exchanger bone dry, dipstick base too.

    Possibles as I see it - rear main seal (unlikely as there is dripping on the long driveshaft), oil temp sensor allowing oil through, rocker cover or timing chest leaking. Have degreased for now, will await further "exposure" of the possible sources.

    A friend dryly commented on this, the car I named after our infamous St Kilda Girl - "Of course it wants to be the centre of attention!"...

    I had a serious leak from the firewall side of the engine - it was leaving puddles on the ground !! I could'nt figure out how to get at it, and was too nervous to ask a mechanic, in case it was a blown head gasket!! Not aware of ever seeing any smoke though...

    Eventually gave in and asked David Glock to look at it (unfortunately he has since sold the business). Turned out to be oil pressure sensor - cheap fix compared to a head gasket!

    Hope yours is something quick and easy.

    Cheers

    That could tally, as I've been getting the "full monty" dash warning lights too. You may have nailed it...

    The oil pressure sensor is reached through the offside front wheel arch. I used a 22mm deep wall wheel nut socket to remove it. Its plastic back was loose in the swaging, if I sprayed degreaser in the measuring orifice it ran out the back around this crimped section.

    I melted out the plastic back and brazed a screw into the orifice, then tidied it up before refitting. The sensor plug is cable tied out the way. Louth's have two new genuine sensors left, as I think the failure is exacerbated by heat-driven shrinkage of the plastic, does anyone want to go in with me - they'll be $30-$35 a pop landed? Also fits early 406 and Xantia 2 litre motors.

    Shortly off to fill up and test for leaks!!!

    Well, that didn't work very well, did it?

    Worse than before, a lot worse.

    Twisted seal or cracked housing ?

    I'm really sorry that it's got worse for you.

    I suspect the blob of braze has bottomed out in the sending adaptor before the edge seal crushed down properly. If so, it's at least an easy fix - ignoring the pre and post cleaning. As a "motorcycle aware" driver I abhor leaving oil on the roads. It's just not fair.

    They seem to have a finite life!
    Mine did not provoke any dash warning lights - just leaked

    Appears fixed (the leak). A tiny defect in the brazing was the cause, so I re-flowed it with more paste flux and a dab more braze.

    Access to the sender is very easy with the OSF wheel and splash guard panel removed, I also unbolted a harness clip from the timing chest.

    Finally refitted an OEM pressure switch. LCS Louth had a few, I purchased a pair for just under $60 posted, so the other (now weepy) PRV could be dried up as well. Only drips under the car now, are coolant.
