Alright I think I might be screwed here. I've got two engines apart here that are n/a's a just got one together but the weights are alittle different with the hole in them and there are no markings. How would i got about finding which one I need?

 

Same series? Both non turbo? If so I don't think it makes a difference which counterweight goes on which engine. Same with the built in counter weight in the flywheel. Both flywheels, I think, will have the same number embossed on the engine side of the flywheel. Like N332 as an example. I'm sure somebody will correct me if I'm wrong about this.

go to the grecery store and weigh them in the vegtible section

 

Well i thought there were the same also but the position of the whole on the edge of the weight is in a different position and one is deeper than the other.

 

Well i still wouldn't know which one to use.

 

yeah, but it would tell you if they are the same or not, i would tend to think they are the same

 

It seems they could be the same weight but just on the wrong side so it would not work. I'm probably going to have to just try one and bit the bullet.
