hey guys well i bought my car not long ago and the previous owner didn't really take care of his car.

I found pieces in the engine missing and things disconnected.





Can anybody help me identify the parts highlighted red so i can replace them?
im a noob when it comes to technical engine stuff so any info on what each part does would be great and if anything could break if i continue to run the car as is.

Thanks

 

The missing hose is called a heat riser tube it part of your emissions.
The hose that you say is crusty is the upper radiator hose you should replace the upper and lower at the same time.
The other thing you said was disconnected is hard to tell from your picture need a better picture.

 

Heres a better look.. it was originally disconnected for a long time..but i got it hooked back up, im curious as to what it does exactly

 

Crankcase breather. Reuses crankcase emissions rather than venting to atmosphere. Rust on serpentine belt pulleys makes it look like it sat without running for awhile. Replace any water or heater hoses that have soft spots. May also want to replace that belt if it is cracked or worn. Looks like the same 5.0 TBI engine I have. Lots of great info on TGO to help you out. Welcome!

 

Is there to put hot air into the engine for faster warm up on cold start.Is operated by the vac pot shown on top of air snorkel

That hose from air cleaner is the supply air for PCV system.
Vac sucks the fumes out of engine from drv side rocker cover through the hose shown in top pic

 

Thanks for the help and welcome guys.

Gonna try to get these parts asap even if i can run without them.
