cheekymonkey Posted May 25, 2007 Share Posted May 25, 2007 Guys, Yes having a bit of a car day today. Fitting wiring harness and FCD. Undid the ECU harness and felt a bit of oil like substance. Whipped the ECU out and you can see in the pic I have some oil or something in the connectors. Is that normal? There's no evidence of any leaks, no oil anywhere else in that area, and the rest of the ECU looks great! Quote Link to comment Share on other sites More sharing options...
Homer Posted May 25, 2007 Share Posted May 25, 2007 Odd. Are you certain it's oil and not manky coolant? Quote Link to comment Share on other sites More sharing options...

cheekymonkey Posted May 25, 2007 Author Share Posted May 25, 2007 How bloody weird! Without having any problems, or knowing when this could have started, I'm going to open up the ECU for a visual check, if everything looks OK I'll give it a clean and connect it all back up. Now I've seen everything! Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted May 25, 2007 Share Posted May 25, 2007 It's not coolant then. Yes but it could be that highly toxic contact lubricant:( Nah! just kidding:d Quote Link to comment Share on other sites More sharing options...
JustGav Posted May 25, 2007 Share Posted May 25, 2007 Get yourself a can of electrical contact cleaner (halfrauds or maplins usually stock it) Quote Link to comment Share on other sites More sharing options...
cheekymonkey Posted May 25, 2007 Author Share Posted May 25, 2007 Maybe it's ECU fluid leaking out from inside? Hmmmmm... Quote Link to comment Share on other sites More sharing options...
JustGav Posted May 25, 2007 Share Posted May 25, 2007 Maybe it's ECU fluid leaking out from inside? Hmmmmm... ECU fluid? I hope you mean that as a joke? Has the car had a matrix changed by any chance, it could be just some old crap that was left behind... Quote Link to comment Share on other sites More sharing options...
cheekymonkey Posted May 25, 2007 Author Share Posted May 25, 2007 ECU fluid? I hope you mean that as a joke? Has the car had a matrix changed by any chance, it could be just some old crap that was left behind... No it hasn't had anything like that changed as far as I know. It was only a very small amount of oil, might check again in a couple of months. At least if it is a problem, it's only going to get as far as the fields harness now, and not the ECU!

If you open it, the Supra will cease to exist. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 25, 2007 Share Posted May 25, 2007 Someone has sprayed the connector with something like WD40 in the past, probably to try and fix an iffy connection, it has eveaporated to leave the oily base you see, that's my best guess.

JustGav Posted May 25, 2007 Share Posted May 25, 2007 Have you checked the grommit up by the engine bay section where the loom goes in, if oil is getting blown onto the loom it could be running its way down the entire length of the wire to the ECU, however you should be able to feel the oil/gunk on the wires leading up to the ECU.

Hahaha, occam's razor strikes again... The simplest solution is usually the right one... I didn't even think about something like that...

cheekymonkey Posted May 25, 2007 Author Share Posted May 25, 2007 Yeah I'm with CW on this one purely because it's the one explanation I hope is correct *grin* There's no oil anywhere else at all in that general area so hopefully I'm OK.
