Hey,

The 3100 in my mothers 94 Grand Am blew the other day (knocking really bad), and as I project for my own personal expierience I want to try and pull the motor and replace it with a junk yard engine.

I have never pulled an engine before so this will be a learning expirience. Is there anyone that can give me a run down on removing the 3100? Any tips are appreciated.

Thanks!

Buy a Haynes manual for that particular car ($15-20 at most) .. that'* the best advice.

Also, why not replace it with a 3400? same bolt up.. IDK what else is involved, but it'd be a nice swap.

If you can afford it, a factory service manual off eBay would be great. Haynes are OK but GM literature is much better.

As for pulling the motor, just take your time and work slowly. Label everything and put your screws/nuts/small bits into small baggies and label them. When you get the motor out, clean everything as best you can.

When you get the new motor you might as well get it clean too and install new parts whiles its out. Timing chain/gears/dampener, freeze plugs, water pump, etc.
