This theme seems to repeatedly occur for me. Brand new internal cap going bad prematurely on a V1, left me stranded. No problem, switch to external one. Problem solved right? Wrong! Wether it's from Treatland, Advance Auto, O'Reillys or even Napa, all are questionable. Most recently an external from O'Reillys on an M1 Colt let me down before I could even clock a number of test runs after the rebuild.
A mechanic friend who serviced Nissan and Hyundai would tell me of customers bringing their cars in unable to make them run right after just installing tune up parts from Advance Auto and such. He would tell them he would throw them away and install genuine OEM parts.
I once was stranded in a 90 Saab 900T because I didn't replace the cap and rotor as general maintenance. The parts store crap lasted not even a year. I was stranded and would have used a cap and rotor if it was made out of old egg crates just to motor on. But really?
Have any of you found a source for higher quality caps that last as long as they should? As a rule these things fail just sitting in a drawer for too many years but you can't even count on Blue Streak brand anymore.
Suggestions? I'm adding a clip on external cap to my tool kit. They usually fail as open, not shorted so it should get me home.
