I started my car for the first time in about 4 days and held revs around 1500-2000 for about 4 minutes... Quite a large wet patch formed under the exhaust (which is angled at the ground), smelling slightly of fuel/oil...

Just wondering if this is a worry... I just had the car dyno tuned not long ago, so it shouldnt be running rich.

Cheers,

 

Most likely just some moisture in the exhaust system. Smelled like oil/fuel because of engine being cold and running slightly rich. Should be OK, doesnt sound like it was a lot of liquid or too much to really be worrying about.

 

hmm I used to get a patch like this normally warming my car up... but I used to warm it up at 1000-1500rpm... recently read that this isnt good as it will build up carbon in the engine.. so today was the test of the 1500-2000 warmup, a fair bit more moisture than usual, but maybe thats due to leaving the car for about 4 days.

no worries hopefully my cat wont die..
