What Part is this for my Blue Top 16v?

[Winddrifter86]

I have a 1985 Corolla GTS but the engine i just bought is out of a i have no clue it was most probably a MR2 cause the T-VIS i got was backwards but i dunno which one i should use for my corolla gts cause i have 2 different parts that go into that same spot

In this image the upper left one is off of the engine i got 2 weeks ago that red cap is plugging fuel the yellow tape is pugging air and the green clip is a sensor

the one on the lower right is out of my last blue top and it only has 2 sensors
not before my last blue top my mechanic may have taken it off of the red top i had before that?



ok in this pic the 2 parts switch sides, the upper left one is off of my last bluetop? redtop? and has 2 sensors and a coolant hose on the bottom

and the one on the lower right has a sensor, air line and red cap.



basically what are both parts called? which one should i put in my 85 Corolla GTS?[/img]

This is where the part goes onto the cylinder head

That looks like the rear oil junction where the temp sensor for the gauge goes on.

Remember to get the appropriate gasket for that.
