1994 Acura Integra engine

Hey guys,

I test drove a manual 1994 acura integra. It had a swapped stock 1.8 4cyl. Honda/acura engine that has 70,000 miles on it. When I test drove it the engine made a ticking noise that got louder with acceleration. My friend has a 1995 honda accord that also makes a ticking noise and says that its just a typical honda engine noise. The car also wasn't driven much.

Do you have any idea what this ticking noise is? And do you think its worth buying?(I dont plan on having it for more then a year or 2)

Thanks, Eric
