blow some carbon off the valves 

When one finally has sex after an extended period of abstinence. Sexual intercourse is compared to starting an engine that has been sitting for a while and has accumulated excessive carbon deposits in its inner workings.

Dude, the last time I got laid was during the Cretaceous Period, I've gotta blow some carbon off the valves .

working the valves 

When a man has just pulled up to a urinal in a public restroom and has a gas bubble drop to the back gate at the same time as the flow is about to start. At this moment, a friend walks in and calls you out by name. Now your identity is revealed to others that are in the stalls. With this happening, you can no longer let the brown cloud come flapping out. The only thing you can do is limit the flow with enough squeeze on the urethra that didn’ doesn’t compromise the rectum seal.

Fuck man, my boss walked in to bathroom right when I pulled up to the urinal. A gas bubble dropped and I was working the valves to save myself from an embarrassing fart.

16 Valves!

16 Valves was a defining moment in the development of the combustion engine. Any car fitted with this technology had performance that was unsurpassed by any other vehicle on the road with the exception of Turbo or Twin Turbo cars. Vauxhall were renowned for their 16 valve technology and deployed it across a range of its hatchbacks none more successful in sales or performance than its Astra GTE. These cars were so fast that they were quicker than shit off a shovel. High recognition indeed when gauging 0-60. Astra GTE's were almost exclusively owned by the rich and famous except for the many tens of thousands that could be found across the council estates of the U.K.

The R's must be doing very well they are driving a 16 Valves! Astra GTE they are like shit off a shovel.

Hmm you say that but they didn't pay the extra to have it in a metallic or pearlescent colour they've just got it in a bog standard ROSSO RED.

lapping valves

Lapping valves is how people attempt to save money on a valve job and kill power at the same time.

I'm to cheap to go to a machine shop so I'm lapping valves myself.

Fukushima Release Valve 

The progression of the Japanese Blindfold where the groom proceeds to go further down the bride's face, and his anus envelops her nose as well, then farts spewing toxic gas out of her mouth and into the air. Results in a subsequent Howl at the Moon, and possibly what can only be known as The Hiroshima.

Note: While hilarious, this is not a recommended progression of the custom since it has resulted in pink eye and bacterial pneumonia.

I can't believe he pulled off the Fukushima Release Valve! What a lucky biride.
