Guys, my newly transplanted 12ht is smoking bluish grey. It is a jdm engine fitted to hj60. I haven't test started it before fitting but changed some of the leak-prone gaskets and seals. I removed the sump to inspect if everything was good from underneath and resealed back after seeing everything was clean. I also removed the turbo and and changed the gaskets. The turbo wheel had some slight up and down play on the axis but no other play and turned without resistance so bolted it back. My overall impression on the engine condition was positive and hoped it would run good. I haven't dug deeper into the engine. It was quite an ordeal for me as this is my first engine swap. Due to lack of my experience and knowledge about diesels I removed the fuel pump and reinstalled without aligning the timing marks and force started it using some starting fluid. It ran horrible and smoked huge clouds so shut it down after 5 or so minutes. After consultation with local diesel people I was told that I needed to align the timing marks so removed the fuel pump again and aligned the pump timing using the window on the timing cover which was discussed here. The engine ran much better but still smoked bluish grey after pump timing alignment. I was hesitant on the timing window method as there was no proof it worked ok for other mud members, so this time I removed the timing cover and aligned the timing marks according to the service manual. After all this work the engine still smokes grey white with blue tint. I wouldn't say it is blue smoke it is kind of grey bluish. One thing I noticed is that the there was small oil pool collected in the turbo intake side pipe but there was no indication of blow by from oil cap and dip stick. I need your expert opinion what may be causing this smoke. Some say it is worn rings, valve guide seal, some say it is turbo seals. Thanks in advance. I will try to upload a short video.
