Honda-Tech - Honda Forum Discussion - distributor internal seal replacement question 97 accord

I have the common oil leak coming from my distibutor as well as the lower spark plug o-ring leak on my 97 accord lx. i have replaced the o-ring on my distibutor, but i did not replace the internal seal of the distributor (i have a brand new seal for it). i wanted to take the distributor apart to change the seal, but my dad who is a mechanic advised me to not mess with the distributor since my car has 200,000 + miles on it and because distributors are sensitve esp if taken apart. my question is, should i buy a new distributor? (my current distibutor works fine, i just want to stop the oil leak) new distrtibutors at autozon are $280-$300... i do not want to take a chance on a used distributor since i dont know how the seals are... i have a shop i go to regularly, if i bring them the seal how much should i expect to be charged to have a shop replace my distrubtor seal? i know it is not a hard job to do, but i dont feel confident in doing it myself... I am going to attempt to change the lower tube seal o-rings myself and i am a little nervous about it. i watched the video posted on here that shows how to do it and i am mechanically capable of doing it, but i have never done internal engine work so this is new territory for me. after the lower o-rings are replaced i am going to get a vale adjustment / timing adjusted on my engine (just had timing belt and water pump replace and just changed all tune up related parts plugs, wires, rotor cap etc.) and thats when i want to have my distributor seal replaced as well. Any advice or recomendations would be a huge help as i only have one day to figure out my plan of attack for my honda.
