Hello Miata Turbo community - you can read some (really old) stuff about my '91 at Mike's Miata's Homepage
- not much has changed, except that I've been using the Miata as a daily driver for the last 8 years or so, and not working on it much other than for maintenance.
So, after driving home the other night, I noticed a little puddle forming more or less under the master cylinder on the floor, smells like coolant... look under the hood - hey, coolant leaking from the bottom end of the leftmost heater hose - no biggie, order up some heater hoses from the dealer and wait...
So, while I'm taking off the old heater hose, it doesn't seem to be in bad shape at all (pretty remarkable after living that close to the turbine exit for 11 years, but I guess that heat shield worked...) the heat shield did, however, seem to have a LOT of corrosion under it where it was on top of the metal pipe. Hoping that the corrosion just pushed a leak open under the hose (yeah, big hope.)
So, got it all cleaned off, got the new hose in place, and voila' same leak, but this time I can see it - it's coming from a pinhole on the inside of the bend in the coolant pipe (the one on the engine side of that leftmost heater hose....)
So, here's the question: just how hard is it to replace that pipe? I see that the exhaust manifold has to come off - is that it, or are there other gotchas? I'm assuming with all the turbine exit heat running around this forum that someone else in here has seen this particular problem before?
Or - another route - does anyone know of a good (trustworthy, does quality work) mechanic for turbo Miatas near Gainesville, Florida? I have done most of the work on my car myself over the years (except the initial turbo install) - and when I get something done by a "professional" (other than the turbo install) I generally get really disappointed to see that they slap something together 5x faster and twice as sloppy as I would have done myself.
Thanks in advance for any useful advice.
