Well my 1986 22R toyota pickup automatic 2WD started to shake on idle today when I turned it on. it shakes even more when idle on drive. So far I have changed the PCV Valve, spark plugs and Distributor Cap. The Carb was replaced like 2 years ago. I also hear a bit of ticking on the driver side of the engine and there is a blue and sometimes black exhaust smoke when I give it gas.

 

Compression or leak down test

 

Funny thing is that I turned it on earlier in the morning and the vibration is gone. Engine is now more quiet (still shakes a little in drive idle) Hmm I might need to observe it more. Thanks
