I drove a series II in a 95, but the little more umph wasn't enough to change my mind. And besides, you can always do some simple mods to the car, and make it sound great, and perform as well, if not better then a series II.

Willsbonnie,
The first indication that a series II intake is on its way out is the gradual loss of coolent with no apparent leak. If you notice that your coolent overflow is low, top it back up to proper level and monitor it closely. If it goes back down again, you are in for a replacement. They will last anywhere from 50,000 miles to 100,000 miles and there is no other way to anticipate a failure. If you neglect this repair, you will get hydrolock when the intake manifold gets bad enough (hydrolock is where the pistons pull coolent into the cylanders in the intake stroke and can't compress it in the compression stroke). This is VERY bad as it will bend your piston rods or break your wrist pins. Even if you don't suffer from hydrolock, you are in serious danger of introducing coolent into your oil which will starve your bearings from vital lubrication. This results in spun bearings. Lastly, even if your bearings, piston rods, and wrist pins survive, you are in danger of overheating from lack of coolent, in which case your engine could seize from lack of lubrication.
Asside from this design flaw, the series II engine is one of the best V6'* made. It is reliable-often lasting well into the 250,000 mile range.
JrFaust,
Where have you been? I've been around here all alone with my SC SE for over a year. Now all of a sudden we have five SC'd SE/SLE'*. We all need to get together: 95SCSE, JrFaust, sle-sc, JoshkerLS1, and me, 95BonnevilleSESC!
