Hi. There is no "THE" TBi engine, there are slightly different variants for the different platforms (Giulietta, 159/Brera/Spider, 4C, Lancia Delta).
The only manual I have, concerns the TBi engine in the 4C: Alfa_Romeo_TBI_10_ENGINE.pdf
I found this file some time ago and don't remember where, but as of today, it seems it has disappeared from the web.
If you know someone who has access to the current online ePER, maybe he can extract the instructions for the other engine too.

 

Ok thanks. I knew there where some differences, but I was hoping to just find at least one and use it as a general guide.
The car is anyway a 2011 159 TBI.

P.s It is a lot of good information in your file, and I thank you for that. But there is no information that could help with a rebuild. Like torque specs on head, crank and rod-bolts etc. As a minimum I need that, and ring gap and bearing clearences.

 

The trouble is that eLearn for later car's was only available as a subscription web version I think.

Try this: 4C TBi MANUAL.pdf

 

I can get access to it; what specific area are you looking at as it would mean me going through every section and manually requesting it.

 

Cool!

If possible, The most important would be torque specs on bottom and top end, as well as ring gap and rod and crank bearing clearence spec ment for the cast iron TBI block from the 159.

 

Thank you very much!
