Hey guys! Just wondering about an oil leak I've recently developed at the front of my engine. It is NOT due to oil pressure (I have checked this extensively and maintain a clean flame trap/PCV system), and it gets very very prominent with heavy driving. Around town the leak is minor, but after driving uphill for an hour and climbing a few thousand feet of elevation I had a solid leak running out onto the exhaust pipe, smoke everywhere. Driving flat ground I don't get this dramatic of a problem, and it only drips a few drops parked overnight.

I'm just wondering what the correlation between heavy driving and this leak might be. Is that pretty standard for most front engine leaks, or does this narrow down which of the seals I should look to replace? Seems like either front cam, crank seal, or valve cover but this is all new to me. Degreasing the engine didn't help pinpoint anything because (i think) the leak is coming from beneath the timing belt cover.

If that sounds familiar to anyone I'd love to hear your thoughts, thanks fellas!
