One thing I have found is that these two engines I just set the valve shims on were out of sdjustment by quite a bit, the engine from japan is so carboned up it is crazy, I have to take it for a couple hundred km run to get it all warmed up and burnt off. But, when i set the valve shims the numbers were way off - I suspect carbon was messing up the numbers. One shim I put in was very thick and went against my better judgement - anyway the first time I stated the engine I got the hot intake manifold from the intake valve being partially open. So - the lesson here is that if your tolerances are out .25mm then you are going to have excessive heat and other issues - so set your valve shims if you already haven't.
John, where did you find that part number? On toyodiy? How much from Japan? Toyodiy says it is for an HDJ80 1990 - model.
One interesting note, per Dave, he has seen some HZs that came with boost compensators OEM. His recollection was that that version showed up in Japan around 1993.
Why would a 1HZ, being NA, come OEM with a boost compensator?
