Hi all,
I'm looking to do a partial rebuild (pistons only) of my 12ht 390k with suspected blow by. After researching the wear and tear of worn pistons and rings and potential damage caused, it seems Alfin insert pistons are the way to make the most impact to durability and may be possible for a "home job". It's at the mechanics today for a compression test and will see what the results are. I would love to rebuild myself, (very handy with the tools and have done all other work to date and some engine work too) but I don't want to take on something I can't complete or risk messing something up. Does anyone have any idea or experience on the level of work, skillset, tools, processes involved and if a home garage job (clean and tidy one at that) would be out of the question??? I'm trying to save dollars but also really enjoy getting stuck in myself.
I know a full rebuild is the way to go but obviously, cost, time, and out of my scope for sure. My idea is to just replace pistons and rings, not a full rebuild and give a general once over as the engine runs well otherwise. Also for just pistons, would the engine be able to be worked on in situ, despite the awkwardness of restling the fenders???
Either way i'll be getting the injectors serviced, installing an intercooler and potentially having the turbo overhauled.
Please comment anything else i've missed, or should or should not do.
Cheers for any help.
