I have a 2008 caravan that the starter grinds only when it is cold out.Otherwise it starts fine.Is the starter bad or is it something else??The itake manifold gaskets were replaced last week and now it is doing this what next??!!

 

Just Noticed that the starter is covered in oil from the intake leaking.So this is probably why the starter is hanging up.It still works just sticks and grinds a bit in the morning when it is cold.Got a new one on order.Can anyone tell me how many bolts there are holding in the starter on the 2008 Caravan?I see 2 and a empty threaded hole on the starter am I missing a bolt??
