Yes, the cap should go on fairly tight. But not too tight or the gasket will spread. Sounds like it's time for a new cap and bottle. I just had the same problem on my '88. A new cap/bottle solved the problem. I am now on bottle #4 since new. The first two cracked.
You can find the cap/bottle online for as little as $20 US. Check www.rockauto.com
