Actually yes considering the weather and geographical location , etc. We do not get much rust or corrosion here due to low rainfall and/or snow. The motor in the Alero looks really good because it has just under 60K miles on it. My son just drove in from New York with it for summer break from USMA - West Point. 2300 miles one way. After a year there it probably won't look too good. But this is his last year and he graduates May 2009.

Little off topic but we just added a MPR CAI/FWI to it along with an Optima Red Top battery. Pacesetter Monza CATback exhaust system is next once I get enough strength and will power to do it. 2.5" pipe diameter all the way to the dual tips and deletes the resonator. However, I'm all ragged out from work and working on the old lady's Regal this week. Bad UIM and LIM gaskets at 132K miles. You will never believe the symptoms I had on it.

For oil all we ever use is Castrol GTX 5W-30 in the Alero along with a Delco PF47 oil filter.

The 3800 calls for 10w 30 and the 3400 only calls for for 5w30 only.The 3400 is also known for eating cams including the 3100s and I have seen this happen.I have never seen one with piston slap yet.One drawback of sythetic oil is,it will cause gaskets to leak.I know of one case of this on an older car.

You've never had a 3100/3400 with piston slap? Better go start that 3100 and take a good listen. I've never had one round off a camshaft lobe. Did have one break a camshaft at the shop due to a leaking LIM which ruined the cam bearings.

I never seen one do that happen.I did find why the cams get eaten up in 3100s/3400s,mainly the journals from a Jasper rep I know.If you think it is because of the camshaft being hollow in the middle,your wrong.It is in the block,when the block was casted in China.The cam journals were casted offset and GM put in really cheap cam bearings.Jasper fixed it right the first time,they alighn bore the cam journals and put in upgraded cam bearings.Jasper is the onlyone that does this.The block is junk right away when the cam goes bad.
