Blue exhaust smoke on overrun (1 Viewer)

[snapdragon]

Hi
Its been a while since I have posted here.

Rebuilt my 1fz engine last year, all has been well, already put 25k km on it with no issues until now.
I am getting blue exhaust smoke when coasting downhill in gear, and a little on cold starting first thing in the morning.
The only thing I have not replaced in my rebuild where the guides, was told they are good.
Any ideas where I should look? Not interested in tearing motor apart again.

Cheers
Warren

This post would do better in the 80's series thread 80-Series Tech - https://forum.ih8mud.com/forums/80-series-tech.9/
Blue smoke is usually oil. Based off the limited info I would expect the engine needing to be torn down in the near future. Post at the link I provided those guys would know more
