those engines are notorious for leaking intake manifold gaskets...and they kinda suck to do. got to take the rockers and pushrods out etc...I've done a couple. not really fun. goodluck

how savy are you with top-end engine components? It's basically all a puzzle, just in reverse. If it comes of, it has to go back on.

ouch.thanks....its so easy to find how to stuff on ls1's but i cant find a thing on that car/motor

**third_shift|studios** · 10-10-2007, 06:30 PM

you sure it's not a 3.4?

**tonyjnjz** · 10-10-2007, 06:31 PM

pretty sure..dosnt say it on the top of the block..thats what i was informed that it is when i picked it up from my buddy last yr...96 monte base model...top of the intake dosnt say a thing...no 3100..no 3.1..its pretty fukin slow though

........ah wait just remembered..yes it has to be the 3.1 ..when i looked up the oil filter i did it for the 3.1 ..it fits..and the 3.4 had a diff filter

**third_shift|studios** · 10-10-2007, 06:35 PM

i did some quick googling...it seems the 3.4/3.1 L share a lot of commonalities. perhaps you can google some 3.4 rebuilds?

Pull the upper and lower, you shouldn't have to pull pushrods for a manny gasket. go check out www.60degreeV6.com

I've owned my share of 2.8 and 3.1 chevys. Its been a LONG time but I don't recall removing pushrods for a intake, thats just crazy. Infact I never took the pushrods out for anything other than lifter change.

**Chaos** · 10-10-2007, 06:56 PM

this is not the same as the older 2.8/3.1 engines.

**tonyjnjz** · 10-11-2007, 12:53 PM

ok it IS the head gasket blown!!! its SPEWING right out of the bottom of the head....1100 dollar job to have done ...OUCH..anyone wanna buy a 96 montecarlo cheap....77k miles ..body great shape

How is it different when they are all 60 degree V6 motors? example, you can bolt 3500/3900 heads and intake on a old school 3400. and you can swap 2.8 and 3.1 parts all on the 3.4 also. I have had alot of Fieros

Step 1: Remove v-6 trash.

Step 2: Install LS-1.

Step 3: Enjoy life.

here, maybe this will help you understand, notice the position of the pushrods, and where the intake gasket is. The push rods are behind and go through the gasket. The pushrods have to come out to replace the gasket.
