Right my motor has done around 700 miles since rebuild and already the cam cover has leaked everywhere.

Question is - i've been using stainless bolts over the original mild steel is the engine getting hot enough to make the stainless expand enough to make this leak?

I have purchased a full set of mild steel to test this out but just curious as this only started after stainless was used i just didn't think it would get hot enough.

Cheers
