In my 88 RX7 I had to replace the water pump seal, and while tightening down the bottom nut by the main pulley, I heard a crunch, and it felt like it was threading easier. Now when the engine turns over, there is a horrible clunking sound, and the bolt moves around. I am afraid to start the car. Did I break my rotor housing? Thanks for your help.

 

hmm sound slike you messed seomthin up.....

maybe it broke oinside of the water pump?? and its hitting, take off the water pump and water pump housing again and see what broke.

I dont know but i read this one time and thought maybe that could be it. Check it out.

 

i took the water pump and housing off to discover that the bottom bolt busted through the front cover for the main pulley set up. It cracked off a good 2-3 inch chunk and the bolt bent on one of the balancers. How hard of a job is it to take the front cover off? Thanks for your help.
