I have 2 completely different sounds coming from my engin.
1. when starting up (cold) and a slow acceleration theres a water/bubbling like noise, almost like water is sheeting off a surface or being pumped thru tubes. maby thats all it is.
2. when moderatly accelerating (cold/warm) at 3250 rpm's theres a rattle that sounds like something like a rod of a sort is rubing against a peice of metal. its only for a split second but is consistently at 3250 rpm's.
any help or suggestions? thanks in advance
