Samurai 20V Posted July 14, 2018 Share Posted July 14, 2018 Hi Gents. Was fixing a vac leak today, found a "leak" on the map sensor. Seems a very thick sticky substance. Is the sensor stuffed? Does it have a gasket? Car seems to be running normal. Thanks. Link to comment Share on other sites More sharing options...
Durandal Posted July 16, 2018 Share Posted July 16, 2018 That just looks like some oil as it is all over the connector as well. Possibly from the pipe above it? Link to comment Share on other sites More sharing options...
Samurai 20V Posted July 16, 2018 Author Share Posted July 16, 2018 Nothing above the sensor.. Link to comment Share on other sites More sharing options...
Durandal Posted July 16, 2018 Share Posted July 16, 2018 (edited) I've seen oil collect around there from the valve cover or a split vent hose from the valve cover/PCV system. In your pictures it looks like it has leaked all over that area. Could be residue from the intake coming out where your vac leak was as well.

Samurai 20V Posted July 16, 2018 Author Share Posted July 16, 2018 Thanks, will pull the covers off and check the pcv hoses. Link to comment Share on other sites More sharing options...
Samurai 20V Posted March 29, 2019 Author Share Posted March 29, 2019 Just to close this off, the "leak" was the underside of the sensor that had melted.. Was still driving fine though.. Link to comment Share on other sites More sharing options...
