Cats are on . . . no smoke though . . so should I still look for a leak or could it be masked by the cats if it is burning internally?

With a window down... that smell of Burning Kendall 40wt will catch right up to you at every stop sign and red light. I did love the puff of Blue that trails behind you at every shift!


However that's not the case here. He already said his engine isn't belching smoke out the exhaust.

Yup, valve/rocker arm cover (whatever you want to call them) gaskets would be the first place I'd look.
Not too difficult to replace and very little coin, although mine have lasted for almost 140K miles so far.

Actually, even before that, check to make sure that your oil filler extension is seating in that cover, and that the o-ring is not mangled/torn/chewed-up, same for the filler cap itself into said extension.

GC is great for seals. Our 2001 Impala has no loss with GC. Mobile drive clean 5000 10w30 leaked one quart per 1,000 miles. The leak was visible at the intake gasket, and that gasket was already done twice by two different mechanics over the years. Though the previous times the gasket was done was for anti-freeze leaks. I switched to GC instead of doing the gasket. The leak became small right off the bat with GC and continued to reduce to practically nothing over the first 300 miles. After 5K miles the oil was still full on the dip stick with no make-up oil.

So even though oil must leak from an engine and burn on some hot surface for you to get an oil smell, along with being a very good oil for the moving parts, GC does a great job of helping gaskets and seals not leak.

There was a post here on BITOG about GC and Mercedes having a recall because they had many vehicles have main seals leak, and Mercedes did not specify that they had to use GC. The owners who used GC had no leaks. The others had to get the main seals replaced under the recall and then use GC.

BTW if you go to the Castrol site and look at the data for Edge it looks like the specks for 0w30 are still the same good old GC.
