**grin** re: injectors, now with question.

yep, i got the new washers too. spent an hour or so driving to the nearest autozone. suckage. i love the small town 99% of the time, but not when i have to drive an hour to buy a damn socket.

I ended up making one out of a 6 point deep 1 1/8" impact socket...using a carbide burr and my die grinder. I had an old spare injector lying around to keep checking with...

Did they have the ones like I got, with flutes in each corner?

Sorry to hijack here, but i just replaced the t-stat in my 6.2 after i got the truck out from sitting for 10 years and when it warms up it stays at about 165 - 170 all the time. is that ok? I bought it at a local parts store, i belive it is a Stant. When i start mine up i get some blueish smoke out the exhaust then it clears up after a couple of minutes at idle. I'm thinking about putting in new injectors in when i get some extra money, they are the original ones with 114,000 miles on them. Once again sorry for hijackin your thread.

that blue-gray smoke is unburned fuel in a cold cylinder. pretty normal for these engines.

so, it wasn't a difference of nite and day - but it is noticeably better on start up. i'm not sure how many gp's i've got dead right now - but i think it's 3, which would make a significant difference on start up. i think i was going thru plugs quick because i had to use them so much to get the truck running due to the jacked up injectors. i'm not going to replace the gp's till after i put the crossover on, because i'm going to park this rig and not drive it while i work on that over this winter...

thanks for all the help!

Max, to answer your question, I am running a 195 degree AC-Delco stat in my 6.2L. It runs about 200 degrees at all times. The injection timing is a bit advanced to try and pick up some power, along with a slight increase in fuelling. Its the worst when you are just idling around, but will continue to smoke if you are keeping it in 2nd gear / low range at about 1500 rpm or so.

Once I hit the highway again and start driving normally, the bluish grey smoke dissapears right away, only coming back as a very light bluish / black haze if you've got it pinned trying to keep speed up a hill.

Once you idle for a few minutes, the smoke comes back again, and doesn't go away till you start to move again.

I know the engine is a bit low on compression, it does have around 200 000 miles on it.

yessir.

Cool. I was worried that they might have changed the design...

Yeah, everything needs to be in good shape or you will get the idle smokies, whether it is an IDI or a DI. A slight haze at WOT seems normal for the NA motors.

Is there any where local I can get these copper washers? I want to get them in this weekend. They have anything special about them or are they just a regular old copper washer?
