Hey guys I just bought an fd and on cold start in morning I will notice coolant smelling smoke coming from the dump pipe area after about 1 minute running and disappears after about 30 seconds to a minute. I know it's coolant because I poured a bit on the hot exhaust when I started it. No smoke from exhaust except if it's heaps cold the classic rx7 run rich smoke up for a second. Runs perfectly fine and turbos spool up perfectly. Engine sounds perfect and no missing or anything. It seems the longer it's off the more smoke it produces. Bit worried as I only bought it last week. I need to flush the coolant as it is a bit browny shitty colour but it hasn't really been driven in a year before I got it. Coolant isn't getting worse as I add green though and is not greasy. It's getting more green the more I dilute and not continuing to change back colour. Any ideas? I've done a major service on it but it was doing this before as well. Help!!!

 

And I mean I know it's coolant because when I burnt some it was the same smell*

 

I dont think there is really anywhere to leak coolant around there

 

Turbo coolant lines? Would an exhaust leak dump the cold start running rich smoke even if I can't hear it?

 

I think it's more on the manifold and I see it coming up over the turbos.

 

Might be the coolant outlet that go's to the TB. could also be the lines to the turbo
