Geo metro motor problems, help!

Hi,
I have a Geo Metro 1996, 74200 miles. I bought it 4 months ago. When I bought it, it had a slight sound in the motor like a continuous tic tac. Righ now, it seems that the sound is becoming louder. The previous
owner told me to not worry about that noise. I took it to the mechanic to change the tie inner rods, and he heard the noise and he told me that I need to take the car to a motor specialist to check and adjust the valves. I think it will be very expensive (maybe more than the cost of the car) and I can't afforded since I'm just a student. I was reading some of the problem with the geos in this web page, and I understood that it is very easy to open geo's motor and check? is that true? can somebody with a little bitte of knowledge in mechanics can do it???
Thanks for your help!

You took "don't worry about it" from the person trying to sell it for money? OMG.

Checking valve clearances is generally not a hard job, though I have not worked on a Metro. You do want to make sure that the person doing the work knows what they are doing. A *good* advanced amateur mechanic can do it no sweat, but the question is, how do you know they are good?
The problem with our modern situation is that most shops are charging very high hourly rates these days, so you are in a bit of a bind.
Remember when all of the high schools taught auto shop ???? We are all starting to miss those days already.
