The blonde lady and the 710

Just few days ago i was at the gas station, when a blonde woman drove in and asked for a "710".
All guys present there looked at each other puzzled. Someone couldn't stand the embarrassment and asked : "What's a 710, lady??"
The woman answered "Come on, you know... the one that is located near the middle of the engine. I must have lost the previous one and i need a new one a.s.a.p."
"What is this 710 for? What is it's use?" some other guy asked..
"Well guys... i don't know exactly it's use but i have noticed that it is mostly located in the middle of the engine" the woman answered.
Everybody was so puzzled. Noone could understand what she was talking about. We all felt so awkward since men mostly, are familiar with the inner parts of a car's engine.
The guy at the gas station had no other choice than to give her a pen and a paper and asked her to draw that piece of equipment.
The lady started drawing a circle about 6cm diameter and then she wrote "710" at the center of that circle.
When we looked at the paper it finally made sense :

3 engineers and a broken car

This joke was sent to us by Tigre Marino

3 engineers travel on a desert road in a good old '76 VW Beetle. One is a mechanical engineer, the second one is an electric engineer and the last one is a computer engineer.

The VW Beetle starts making weird engine noises and stops. Then, the mechanical engineer goes back, looks at it for a couple hours and gives his veredict:

"This thing needs a complete overhaul of all friction components, plus the warpage limits of the engine heads are beyond specifications..."

The electrical engineer takes over and starts staring at the engine...after three hours he gives out his veredict:

"This thing isn't working because the voltage present on the battery is not enough, and the electromagnetic effect of the generator is too low for the car to run correctly..."

The computer engineer stares at the engine bay for 6 hours, looking under the mass of cables, hoses, until he stands up and tells his companions:
"We are doomed. I can't find the reset button on this thing!!!"
