Will re torqing the head bolts o na 86 toyota 4x4 with a 4y engine help temporarily with oil in the water ? Im also loosing water but cant see a leak

if the job was done properly , re-torquing the head bolts is not necessary
what is very necessary however is to clean out the stud holes and threads before refitting the head and applying thread lubricant to the stud threads
the problem is when there is oil or water left in the holes before fitting that muck creates a false torque reading
the setting is reached but the head is still loose so re-torquing the studs will sill cause that hydraulic lock situation and the head will still be loose
also all head studs are not always the same length so a stud will bottom out at tension but again the head will be loose
and lastly, head gaskets have a sealant applied that glues the head to the block on operating temperature and that will now be destroyed by the oil and water
all of this is explained in detail in the workshop mmanual

How do you correctly align a new flywheel on a 4y hilux engine.?

The flywheel dose't need alignment it bolts to the back of the crank shaft .
If you are talking about the clutch disk that needs alignment .
You can get a dummy shaft made of plastic they come with the new clutch most of the time .
So you lossen the pressure plate bolts with the clutch disk in place so it will slide stick the dummy shaft witch will be the same as the input shaft on your transmission .
\Then torque he pressure [late bolts and the transmission shaft will slide in I would LUBE it .
