I have no idea if anybody on here knows a lil bit about these 3.1 motors.. but i found one with bend pushrods in it.. and i see that they are two different lengths.. What i am trying to figure out is this.. which positions(cyl,valves) do the intake pushrods go in and which do the exaust pushrods go in. I can't seem to find it anywhere on the net
any gm parts store will tell you. if not look up the stock push rods at auto-zone or part store and see if they have the part numbers for them and the size and they may tell you ex or in if they have more numbers than one for a set
see this is a FWD 3.1 from a 93 chevy lumina euro.. I know that they are different sizes.. but from what i can tell.. there must have been a mixup between the exaust and intake somewhere... i see the exaust ones are long and the intake or shorter.. there is 1 exaust rod bent on both sides.. so what im trying to figure out is where is where are the different size rod supposed to fit at.. like 1st cyl long...2nd cyl short..
The intakes are short and the exhausts are the longer ones...
intakes are 6 inches long and marked orange.
exhaust pushrods are 6 3/8 long and are marked blue
Just look at your intake ports to determin where the intake rod goes for each cylinder,then your exhast pushrods will go in the empty holes,be careful and make sure the pushrods are seated in the lifters.....
