I've always wondered why it only smokes during extended idle. My 4.8 doesn't do it on cold starts or at traffic lights. Only after minimun of 5 minutes of just idling.

Also only smokes if I free rev the car hard after the extended idle. If I just drive off normally no smoke either.

My oil consumption is not bad maybe 1/4-1/2 quart every 3000 miles or so.

Also Lucas Oil Leak Stop does not swell seals and gaskets like some old skool "leak stops". Some old timers I know they used to use brake fluid to swell up the gaskets lol.

But in modern engines seals are made out of viton which is very durable to heat and wear but eventually lose their elasticity over time and what Lucas does is add plasticizers which brings back their elasticity to "seal" what ever it's trying to seal.

I also think there are revised/aftermarket vss that have an improved seal design to prevent it from failing.
