so this gets more traffic than the Chevy section and you guys are awesome other forums not so much. Now on to my issue My 98 Chevy Tahoe 350 vortec threw a code for the injectors I being stupid went to the salvage yard and picked up a spider system well got them in decided I would reuse the intake manifold gasket got it all put back together and it is running like crap rough idle and when I press the throttle it stumbles and shakes and acts like it’s going to die. Is smoking white but not very much at all. When I took the intake manifold off I accidentally got coolant in the intake well I got as much out as I could then check oil I saw no water on dip stick so I fired it up. Let it run for a minute checked out and saw a little water so I drained the oil refilled then flushed again I see no water in oil and coolant is clean. Now it’s hissing from the intake somewhere. And I can see coolant dripping down transmission bell housing but can’t find the leak. I think I read somewhere that a damaged gasket could cause this? Oh pulled intake back off and there is coolant not a lot but it’s in the valley did I just blow my engine are is there hope?
