While working on the timing belt/water pump project I discovered an oil leak around the distributor which has bathed it in oil. Looking at replacement options from local parts places like AAP and Orielys and/or mail order from Rock Auto which offer the following brands. A1 Cardone, Toughone, Autoline and Richporter. If anyone has experience with any of these brands I would appreciate any feedback that is available. Beck/Arnley is also offered by AAP and Rock Auto however the price is substantially more than the other options listed above. Thanks in advance for the guidance.
