Yesterday I drove it for about 45 minutes, it ran great, today I picked my daughter up for the weekend, about 3 hours round trip, ran better then I ever remember it running, smooth. Now it needs to get cleaned up and it'll be ready for spring. It feels great to finally get it back going, its been a long wait, the dynaspark is a good solid piece but Im still nervous about getting it wet, you can see the sillicone around the center and we ran a bead of rtv sealant between the block and the unit, actually put it on the backside of the dynaspark before we set it in place. Im deffinately ready for some road trips. The original opti doesnt compare to the dynaspark as far as quality goes, I'll keep you posted on the durability. If you have a 94 or earlier, then its worth the extra $150.00 for the vents. Ive seen the ones that some people have converted but these vents are built into the unit. They say they will rebuild these if they ever need it for whatever reason and when I first had a problem ( not knowing the computer was bad to ) they gave me some suggestions of things to try and they said they would send me a new one if I really thought this one was bad. By the way, with the new water pump, I dont have that reoccuring antifreeze smell after ten minutes, so far so good and Im knocking on wood.
