3400 Engines
I have a 2002 Oldsmobile Alero with a bad Intake Manifold Gasket (oil in Anti Freeze) Is this the same engine as whats in the Impala's? (2004 thru 2006)?
What is it with these Gaskets in these engines? Should i stay away from all GM's with 3400's? I was looking at a 2005 Impala today, any other resounding problems? Geez Louise J R |

Re: 3400 Engines
The engines changed in the 2006 model years for Impala. The 2000-2005 Impalas that have the 3400 V6 still have the same old 3400 SFI V6 VIN "E" just like the one in your Alero so they are still susceptible to the LIM gasket issue. But supposedly GM installed the new updated LIM gaskets starting in the 2003 and up production years.

Re: 3400 Engines
As explained to this member at the Alero forum he/she has the old style LIM gaskets and all they need is to be replaced with the revised. Important part is not getting ripped off by the dealer or a mechanic.

Bob, Any suggestions on how not to get ripped off would be appreciated The GM LIM gaskets have a piece of hard plastic in the center. I would find a place willing to install a Felpro gasket that has aluminum in the center of the gasket. Also to keep the Dex-cool from going caustic, I would drain the coolant from the rad and the block ( the 3.4L had a block drain plug near the knock sensor) and fill with dexcool and distilled water, no tap water or mineral water, just distilled ( 98 cents a gallon) |

Geez Louise J R[/quote] For the most part Gm has always had a problem with the 3400's but if the 05 impala was a 3800 series they are mint. I have had two cars with the 3800, one was a 1989 buick lesaber where i went through two trannys and no major engine problems and now i have a 05 impala. but i love the 3800 series especially supercharged :P |
