Default Things I learned this weekend

If your car has over 100,000 miles on it, you're way overdue for changing your injector O-rings. All 12. The 6 in the lower intake were grimy on mine, and the 6 in the fuel rail were dry and cracked (on the verge of leaking fuel onto my intake). This is at only 80,000 miles.

If you're going to drill bypass holes in a 180 thermostat, the size of the holes is very dependent on the climate where you live. With the mild climate in Oregon (50F today) four 1/8" holes was too much. The car is running an average of 169 with the heat off. I'd suggest four 1/16" holes in similar climates to mine, and two 1/16" holes in colder climates. You can always go back later and make them bigger if you need to.

When doing a SC rebuild, drink plenty of beer. It actually makes it fun. It also helps when it'* cool out (45 yesterday) to keep the sealant in your pocket to keep it soft.

Oops.

And any time you're working around your TB or fuel rail, have some extra vacuum line handy

Go for it. When you pull it apart, have the GM injector o-ring kit handy, and about 4 different sizes of vacuum line! Actually, the vacuum won't be as bad for you. There'* a rat'* nest of it on the SC cars.

Jeffrey is right. From the dealer, the kit was only 19 bucks, but had parts I didn't need. All 12 O-rings are the same size. If you buy from a local parts outlet, they'll be cheap.

My experience has shown me that while those injectors are out you should take them in and have them flow tested, leak tested and cleaned. Also make sure they put them on a scop during the flow test to make sure the coils are not starting to wear out.

This advice is based off having many high mileage cars and trucks. you wont believe the difference in performace this will make and around my area costs about $50. Worth every dime!!
