Joliesa can fill in the details of what she is trying to troubleshoot.  I'm just posting these up for her.  Good luck Joliesa!

Was trying to determine if my fueling (or lack of) and timing issues were because of leaky caps n all that. Then I  found a bunch of white goup and Im wondering if this is normal.

Unfortunately I no longer think this is my issue as my timing belt is loose. :/ But, feel free to comment of the white stuff!

Definitely not normal. does it come off at all? If so, ide be interested what it looks like under that...    If its altered the surface in any way, then it could be pooched now..  meaning if its acidic/corrosive or conductive in any way  it could mess up the board. Is it the same crap as what has come out of the caps?

The caps are definitely crapped out. you can see the stuff under them in the first pic. does it smell fishy? Time for a new ECU.  :-[ :'(

sometimes people put on stuff to cover up there repair work after soldering the ECU... but that just looks excessive... and i dont think its supposed to be white.

Is it hardend white crap???

thats really wierd.... i agree tho if it stinks really bad and smells its probably the caps leaked out there acid shit.

It appears someone went all out with 2part epoxy on the ecu..    ude do that around things like caps and other tall parts of the ecu. It help make it more structural...   but thats the only excuse for that really..

AND  you wouldnt use epoxy because it would and (may have) burnt the board!

Jordans right....


That ECU is not fried at all. The acid stored in Capacitors is an electrolytic solution between the wound plates. That white stuff is wayyy to thick to be acid.

If you notice where the white goup is...     clearly the person who socketed it want to seal in the caps so they would not leak again.


That ECU is fine.

I promise  ;)

its not grease, its glue of some sort, like epoxy.  From a repair.

Try it in another car that you know is running well.  Try thier ECU in your car.

Fix your timing belt first tho before you try thier ECU in your car.

Miles and Vlad are very good with these ECUs so if you do have an acutal issue with it send it to one of those two.

Jo, I got one you could use, socketed and all... But that also isn't Capacitor 'juice' so i doubt your ECU is to blame.

Log your battery voltage and sensor values.  Bad caps will usually show up as noise on the battery voltage trace and or sensors.
