318/390 stroker kit oil leaks NEED HELP!

i wouldn't worry too much until you've got at least 500 miles on it. the rings won't fully bed in/seal until at least then so you'll get some blowby especially if you 'get on it' and as you've said that's when the leak occurs. keep a check on the oil level and get some miles on it. :thumbsup:
