Were Did This Oil Come From

[axe s]

Hi all...

I put my car in a Dyno day on Sunday, got 420HP on the first run then put a couple of blokes in the back seat and got 466HP anyway the power is not the topic,

When it was on the second run my brother noticed a bit of smoke come up from near the inlet plenum, so i went and had a look and their was oil on top of the oil cap and on the side of the rocker cover and it looks like it has been the point of impact, but i can't think of where it would come from...

probably blew the dip-stick out.

Dip-stick wasn't out, and it comes under the plenum about 10-12" away... and no oil under the plenum..

It's really got me stumped, I thought it blew out of the oil cap but the oil tracks run the wrong way...

any photos of a larger area of the engine bay?

I think u helped me solve it....

I think the injectors and rubbers blew out under boost, it explains the marks on the side of the rocker cover, but not sure about the oil on top of the oil cap. unless the cap seal is RS...

Could be fuel squirting out under pressure?
