I just posted up about getting the injectors and intercooler install finished. However, I now have very light, but very noticeable constant smoke at idle. It seems to be somewhere between white and blue, and was never there before. I also hear, very sporatically, what I think to be a knock.
I turned the IP after the BB's and intercooler went in, but I have almost no smoke at all after 1500 RPM's, and my EGT's are very moderate. I don't know what the timing is, another member is hopefully going to meet me soon to check it.
Any ideas? Could it be just the timing?

It sounds like to me that it could be a timing problem

Here is what I'm thinking. Your IP is a little worn so it's a little retarted. Your old injectors have a low pop pressure than the new ones. So with the old IP they did fine as it didn't take as much PSI from the pump for one to start spraying. Once you put new injectors in with higher pop pressures, the pumps true retarted timing is showing it's ugly face.

Make sense?

Thanks guys. I'll let you know how the timing effects it when I get a meter on it.

Russ, can you tell me what the injectors were set to pop at?
