my car seems to leak coolant only after i take the car out and run it kinda hard. i didnt notice it after just letting it run or runing it easy. the car also loses oil somewhere when running hard. i went to the drags with it a couple weeks ago and make 3 passes and was like a 1/2 quart low on oil when i checked the next day.

here is a pic of the coolant that i found.


it is right where the timing case meets the block. anyone have an idea of where it could be leaking or coming from, and why it only does it when run hard under boost? also any idea on where my oil went?
these may be stupid questions but i dont have a clue as to where to start setting things up diff and what to fix

thanks guys!

forgot to add, we cleaned it off today and then restarted and let run for 5-10 mins and no leak. pressure tested and still no leak. im clueless!

Timing cover, t-stat housing. Try this, drain out some cooland so there it about 3 inches below the bottom of the cap and see what happens.

Assuming you dont have water in your oil or oil in your water, it seems to me youre talking about two different issues...

well i lowered the coolant today and drove it around, got on it and put it to 5lbs a couple times and come back and there was just a bit of coolant there. so what does this mean, or prove by lowering the coolant?

LOL, haven't figured that one out yet!! I haven't had the oil issue, but I have w/ the coolant. That's how I stopped it from happening.
