If leakstop stops a heater core from leakig it just means you completely plugged up the heater core.
Either A. come off the money to get it done..or B. do it yourself.

Or C, for now, block off the heater until you 1. either have time to fix it. Or 2, have the extra $$ to have it fixed. Lots of guys say they started with a heater core in our vettes and the built around them. From what I've read you have to be a contorsionist, and it's best to remove the passenger seat to get at it. OH, and with Morley, if stop leak stops the leak your whole system is going to be gummed up.

i would not ever put stop leak in my car, you need to either bypass the heater core for now until you have the funds to do it or buy the part and do it yourself. bypassing the heater core is an easy thing to do if you need to drive the car, but of course you will have no heat. goodluck
