Default Engine "jolts" when starting car

Searching for "jolt" didn't return much useful information! Not sure what else to describe this as...

Sometimes when I start my car (usually after it has sat overnight), the engine makes a "jolt" (I can feel it in the brake pedal) that I can hear and feel.

The engine mounts aren't completely busted. I just had the car in for service at the dealer (timing belt tensionser was coming apart) and they didn't mention those at all. The only thing they mentioned was a small leak in the transaxle that they recommended I look at fixing soon, but didn't deem "emergency".

Also, it should be noted that it doesn't do this during every start.

Could be a weak engine mount, transmission mount, or a seal somewhere on the engine.

Default I've noticed it before, it's nothing new... just an annoyance and definitely a warning...

... that I need to fix something.

Default What type of seal, in your opinion?

They said one valve gasket was starting to leak, and the transaxle... I doubt/know either of those would be the cause.

I'll call them to verify it wasn't another seal.

Valve cover gasket more than likely.
