Hi guys. First post, I'm in Australia, just bought my forever project car an 05 is300. I'm not so mechanically minded, but if I know the part names and what actually needs to be done. I can fix anything.
I bought this car a few weeks ago, it wasnt running rough, miss firing or anything too abnormal for a 15 year old toyota, just seemed sluggish.

I've done all the fluids and fixed various vacuum hose leaks but this one, as soon as I did a patch job on it. The car started running alot better. I'm not sure if it has anything to do with the pcv valve. Slight Leaks further down and I don't wanna risk damaging it taking it off for further patches.

please what is it called.

also I have suspicions the intake manifold was taken off by monkeys, should I replace the pcv valve and seal just incase

The hose on the right side of the photo is the PCV hose.
The hose on the left is supposed to run to the EVAP solenoid that is bolted to the Y pipe of the intake manifold.
