Young lad ( Was a knob anyway ) at the merc dealership i used to work at was changing the manifold on his 1.6 206 cossie eater after cracking it. Anyways when he fooked off a few mins we nipped over an stuck a siringe full oh power steering fluid down the ( just asking for it ) downpipe.

20 mins or so later he gets it all done an that an starts its up after about 1 min or so thick white smoke starts pouring out his back box an his fookin face went even whiter, he was only a tyre fitter for quick fit an thought he knew it all but shit it when this happened as he did not have a clue what was going on.

We were hidin behind a bonnet of a car on the other side of the workshop in stiches, But sods law the gaffer walks through the workshop on his way home an goes ape shit as the workshop was now full of smoke an we all pissed off home, sneaking out the side door lmao.

Pissing myself now thinking about his face, was a classic
