Re: 3800 series 2 engine swap 97 LS

Keep an eye on the coolant level. I am assuming this is a Normally aspirated engine. They do have an issue with lower intake manifold gaskets that could fail and allow the coolant to enter the oil. You may want to take a couple of hours and change them with the engine out of the car. It will be much easier and it will give you piece of mind.
