New LS3
My original plan was to build my car over 4-5 years. I'm accelerating my plans to two years. I can get a great deal on a GM crate LS3-525. My question is, how long can a motor sit and not run. Are there a number things I should do to keep it like new?

Thanks in advance

My self I would get oil in it. Turn the oil pump with a drill get it all oiled inside. Spray PB Blaster or get the boat fogging spray and put it in all the cylinders. Put plugs in the holes.

If it is going to sit a long time just turn it over every now and again so valve springs are not open all the time.

Main enemies of sitting are the valve springs loosing tension being open all the time. And rust in the cylinders.

All times are GMT -5. The time now is 02:40 PM.
