Oil cooler leak help needed

eagleeye · 06-04-2012, 10:43 AM

I received a new mocal thermostatic sandwich plate adapter from Z1 and installed it over the weekend. It's definitely better than the previous one, but it still leaked a small amout of oil after ~100 miles of driving over the weekend. There was still that drop of oil hanging at the tip of the thermostat and a couple of dried up oil spots on the undertray. The 100 miles of driving included WOT pulls (as much as one can on the streets), highway cruising, and some moderate traffic (in northern VA terms).

I'm not sure where the leaked oil originated - is it possible that the oil is just leftover residue because i didn't do a through enough job of wiping down the plate after the install?

To help rule that out, I gave it a good wipe down this time so I'll just check it again after maybe a week or so.

On a positive note, the oil cooler kit works in keeping my oil temps ~20-30 degrees cooler.
