Hey all, I figured I'd update you on what happened.
So I go to Canada, pick up the motor, drag it to the border in the back of my Jetta wagon. When asked if I bought anything, I told him "car parts". He asked "what kind of car parts?" "An engine", I told him. He just gave me this crazy look, and asked, "you have an engine in the back of a station wagon?".
I invited him to have a look, which he did, and then asked what it was for. I told him "a VW bus" (it was a Vanagon TD motor). He asked how much I paid... I replied in Canadian currency. He said "So, you drove all the way from Ohio to pick up an old motor like this.. why?" I said, they are getting harder to find in the US these days..
I handed him the invoice, I had a sales slip ready, stating that it was a core motor from an 81 Vanagon D with the sellers name, number, address, etc. on it
Have a good day he said..
So, no hassle at all.. I suspect it matters alot if the state you bring the thing into has an environazi stance. IIRC, New York, Maine and Vermont have strict laws about that kind of stuff, Michigan however, does not.
That's my $.02 ....Canadian
