JEGS GM LT1/LT4 Vented Pin Drive Distributor for Select 1995-1997 Buick, Cadillac, Chevrolet and Pontiac Models

Purchased this JEGS brand Optispark and it's been 2 weeks so far and it works great! Very good value. With the price of the others being twice this one or a cheapy for $69.00 on E-Bay which way do you go? I opted to go with this one due to JEGS reputation. happy I did too.

Bought this a month ago and finally got it installed. Included all new timing chain cover seals and water pump to insure the Opti stays dry. Looks like high quality but upon install I found that the Opti has air leaks which is unacceptable for this unit. The Opti requires manifold vacuum and resulting fresh air input throughout the Opti to insure moisture and ignition vapors are constantly purged. This new unit draws air, but instead of through its designated single filtered input, this unit is drawing air in through a leaking case seal/s. In effect, it is a roadside stop waiting to happen if I drive the Vette in wet conditions, which is quite unavoidable at times. After install and testing for vacuum I only had 4 days before this car left for a 1500 mile trip through partial rain so I had to leave the car in the garage and take another of our Vettes to the long-distance car show. Then I had no chance for the reworked C4 Corvette to win her 4th straight Best of Class Trophy. Were we disappointed. I will say though that this Opti works very well electrically and the engine runs powerful and smooth and starts up instantly. JUST WILL NOT PULL A VACUUM AND THIS DISTRIBUTOR NEEDS ITS FRESH AIR! Jegs is great however. Upon a call to them I had a Return Mdse. label on my computer, freight prepaid, with full refund. Great service Jegs!!!!! If I were Jegs I would inspect each Vented Optispark that comes in to insure they draw vacuum as designed. If they don't then back they go for manufacturer correction. Oh, by the way, removing the old opti and installing a new one requires 4-6 hours of labor, including a lot of patience.
