I am pulling the intake manifold on my 1997 C5 the weekend after next in order to replace the oil pressure sending unit. I am also replacing the vacuum lines because they are original equipment.

What else should I do in terms of preventative maintenance as long as I am doing this?

Thanks.

I'm subscribing to this thread because I just picked up a 97 c5 as we'll and the oil pressure sender is on my to do list.

I am planning on replacing the intake gaskets while the intake is off as well.

Take care,

George

Put an extention on it so next time it goes out it's easy to change
Wish I had...

I second that. Put in an extension so that your oil sending unit is a 5 minute replacement that will not require removal of intake, because you WILL be replacing it again. Do a search on the forum for instructions. It's easy, the parts cheap and it will be a Godsend. I did it, and never looked back.
