Hey guys, this is my first thread and I don't want to do a swap so don't just tell me to chuck my v6.
I have a 1988 Camaro, and I took it out on the highway and got it up to about 100, when I need to slow down quickly, and put it into second to slow it down, shifted back into Drive, and it died. I pulled to the side of the road, and started it back up and got home with no problem. The next day I was on the way to work, when it started knocking. I have checked the lifters and replaced the timing chain, and there were no problems. I know it is not a rod, because if it was a rod, it wouldn't go away. When I rev it up to about 2500, it will go away for about 10 seconds, and then come back, I had it idling at about 700, and it wasn't knocking either. I am thinking that it is piston slap. But when i removed the Cold Start valve, the seal was ripped, and now i have a gas leak. I have tried buying a new one, but GM has discontinued the part, along with the whole colld start assembly. Has anyone tried to fix this? Any ideas? I also have looked into a kit from a third party site, that bought up all the discontinued parts, and they are charging about 200 dollars for it, and that is ridiculous. Thanks in advanced

 

You might wanna ask this in the V6 forum.

 

I couldn't imagine down shifting to 2nd from 100mph, and since these ealy computers have no rev limiters, I suspect you over revved it and it may have valve train trouble. the cold start injector tube seal was availible from GM recently, but i found another in a bone yard.
