Series I intake problems will be just like any other car, it'll happen to some people under correct circumstances.

Series II intake problems are factory equipment.

It'* plastic, so it'* possible to damage if it gets too hot, nonetheless. The 180 stat should help.

I'm betting your thermostat isn't opening fully, or is partially restricted. Is the rubber o-ring installed right? The paper gasket? You may want to buy a higher quality tstat and swap it out again.
i didn't get an o'ring with the t-stat..i goat a paper gasket and some gasket glue!

The permanent fix is to get an L67

Just Kidding. You should have purchased a new "O" ring.
