I am not just throwing parts. As I said I did a lot of search on the web on this issue and the pressure switch was a common issue. So since it is only a $30 part I will try that. If that does not do it then I will take it into the shop, but I would rather spend $30 right off then $75 for the shop to look and find the issue. $30 is not going to break me and it works then, sweet.

I know you had a plenum issue, but that does not mean that it is the issue for everyone. After searching I have found there could be several issues and the plenum was the least mentioned solution to this problem. So it might not be that.

 

I completely agree. And $30 isn't to bad. You would be surprised how many people on this forum will jump to 'bad plenum' Prolly the most mentioned thing on this side of the forum anyways

FYI: some local shops don't know about the plenum thing unless they are familiar with magnums. So might want the stealership to look at it, they will know for 100% sure.

Well hope you figure it out, and keep us updated on how the fix goes.

 

What? Didn't you Jump to the plenum conclusion in you first response? Am I in bizarro world?

 

I was kind of thinking the same thing.

 

It never dropped back down -- as opposed to falling back up?

Do you work for The Department of Redundancy Department? Just asking

 

IDK, can you fall up?

 

I can when I'm out of reach of my beer!

 

Haha, cheers to that then.

 

I would be more inclined to say that during your repair of the plenum, you also inadvertantly "fixed" a loose connection at the oil pressure switch, thus making it look like a new gasket fixed the oil pressure issue.

 

Plenum has nothing to do with oil pressure. (aside from making it go low when you suck it thru the engine......) Oil pressure normally drops at idle.
