3.8 series 2 intake manifold exploded
Mine exploded and caught fire 3 days ago while I was trying to jump it. Talk about epic. My last 3 cars have had the same engine with no issues. Had I known this could happen I would have not even considered the n/a 3.8. I'd like to know if this a problem on the series 3?......Also is this a problem on the */c series 2 motors?
My Regal(Goldie) is dead, off to the junkyard on Wednesday. Rip.

How extensive was the fire damage?
The cause is usually a failed fuel pressure regulator, that ended up being recalled by GM. The diaphragm in the regulator ruptures, dumping fuel in to the vacuum system, and in turn, the intake.
Only the series 2 was recalled for it, but I wouldn't discount future series 2 NA cars on account of it, just check for signs of a failed FPR, replace it if you are paranoid (understandably so), then call it a day. Problemsolved.
And no, it'* not a problem with series 3 or series 2 sc, but it'* also not a problem for series 2 NA either once the FPR is replaced.

I appreciate the speedy response. I'd say the fire damage is pretty extensive in my opinion. It was burning for about a good 2 minutes. More than a few wires are charred.
It sucks because I was waiting to take it to the shop to get a code p0446 "EVAP vent control circuit" checked so I could get it smogged...and now this smh
