okay well heres the story, i just recently did a d16y8 swap in my 92 lx. well i went to check the oil and for some reason opened the oil cap ( car was running) then it started to sound like a fog horn, because air was comming out of the hole. im clue less as to why this is happeneing. note. motor was sitting for couple months. question: why is air comming out of the oil cap (when its off) and what might be wrong, and how can i fix it? thanks for the help.
