Wow, this is some serious restoration, much respect!
Don't even want to look at mine now for fear of what I might find!
Great work & a mind of useful information. One day I might take a brave pill and tidy mine.
I look forward to the finished product. Should be one of the finest around!

Curious! I wonder what the escaping part could have been if that's what it was?!
Me too, I would say something came in through the intake port and then melted inside. I haven't checked the compressor side of that turbo yet.

Thanks! But don't look, I also wasn't really expecting skeletons at all before starting this :)

Meanwhile I've resolved the last remaining rust issues. This should have been done by the body shop, but they only did one corner from the four. Fortunately because I scraped down their "fix" which was just flaking sealant over rust.

I've ground down as much back to bare metal as much as I could reach. Then covered with rust passivation, and repeated these a few times. Refinishing was done with epoxy primer, seam sealer, top coat and clear coat. I've tried to replicate the factory brushed seam sealant look, with not so much success, but at least the area is well protected now for a while.

The fix...

I'm stuck a bit with the cylinder head rebuild. Turned out the factory valve guides I've received (said to be the correct part number for this engine) have an internal diameter of 6.5mm but the valve stems are 7mm. The difference is too big for the final reaming alone. Asked Italy but they couldn't help me so far. These guides are also used in QP4 Evo V6 and V8. In fact all of the Biturbos along with the 3200 GT are using 7mm valves. Machine shop tells me the guides have to be pre-drilled. Anyone experienced similar?

Pre-drilling is not unusual. (at least with Maserati). partnumbers : inlet-guide: 475006900 and exhaust-guide: 490007000. (according to my admin.)
