Vacuum advance hose

[fixkick]

Thanks! I found the t-fitting.
The next thing is, there is a tube coming out of the top of the valve cover that has no hose connected to it.

Where would that hose go? to the PCV Tee fitting, it goes.

i (valve cover) but is a PCV hose for SURE. and is revised. 89/90s

ok , the 89s, have many revisions in just 1 year, hose wise. to top of TB for PCV. some have a PCV heater (water heat)
evolution fast changes,

If you post a photo of your engine this is easy to determine.

question did you click all 89 links on right table here.
