I did a bit of searching, but didn't come across much info on this. In my seemingly neverending (but getting closer!) quest to rid my EA82T of all coolant leaks, I think I found that my turbo may be seeping coolant. This would explain the coolant smell (as in turbo=hot, coolant seeping onto it=smell), and the fact that I still have coolant disappearing. Though after replacing intake gaskets/waterpump/etc the coolant loss rate has dropped drastically.
Has anybody experienced a coolant leak from their turbo before? I was looking at rebuild kits, but they seem to only come with bearings and such, no seals. Any advice on sealing this sucker back up? I'm relatively new to turbo's and hoping for some advice before tearing into it.
You more than likely have either a cracked cylinder head or loose cylinder head bolts. You can retightened the cylinder head bolts in a couple of hours by removing the camtower cover, removing the top oil lubication tube and getting a 3/8" x 17 mm socket in there. If you find that they are all tight, then you should think about removing the cylinder head and replacing it with a GEN 3 cylinder head.
The heads can crack between the valves or crack at the fin in the dual exhaust outlet that separates the individual cylinder exhaust outlet. If you are getting considerable white exhaust on startup, then you likely have the exhaust outlet crack.
If you look on the bottom of the cylinder head, there are the raised letters "EA 82". If there is a line beneath the letters, then it is a GEN 2. If there is a rectangular box around the letters, then it is a GEN 3. If you have neither, then it is a GEN 1. From my experience GEN 3 last longer than either GEN 1 or GEN 2. But there are others here who have a different opinion.
If you want some GEN 3's that you want to take a chance and have some cracks rewelded, then I can sell you some for $50 plus shipping. You will likely have difficulty in finding any GEN 3's and it will be nearly impossible to find some that have no cracks.
