Okay I have dilly dally'd long enough and I'm finally getting my LT1 back together. Problem is...I took so long doing it that I forgot where some stuff goes...so I need you LTx boys to help a brotha out!!!

First off... What goes here? This is on the bottome of the block, driver side, just behind the motor mount and in front of the oil filter. It looks like something should be threaded in there but I'm not sure what???



This next hole is not threaded, but is just above the hole in the last pic....I don't think anything goes here, but just want to make sure.



And finally, in this final pic, the rubber tube in the center of the pic that's not connected to anything....what in the world connects to it?



Thanks in advance guys....I appreciate it!

 

Your first picture is where the knock sensor goes, nothing goes in the second picture, and the last one looks like the rubber end of the coolant crossover tube(fallow it back and see if it runs to the back of the heads).

 

The knock sensor is on the passenger side. There is just a pipe plug that goes in the block drain hole on the driver's side.

The bottom picture is the EVAP system vacuum sensor. The hose is part #15 in this diagram from Shoebox's website, and doesn't connect to anything:

Well that's good because I put the knock sensor in on the passenger side!

Would you happen to know the specs on that plug so I could pick one up @ OSH? I don't think I have that plug in the parts pile! haha

Also, Correct me if I'm wrong... Doesn't the coolant crossover tube connect to a small hose which connects to the passenger side of the radiator near the top?

Thanks A TON for the input guys!

 

The coolant return from the back of the head goes to different places on different years. On the 93-95's it goes directly to the connection on the passenger side radiator tank. On the 96/97's it goes to the throttle body coolant connection (passenger side).

Check Shoebox for the pipe plug specs. They will be the same threads as the knock sensor, probably an NPT thread.

 

1/4-18 pipe thread.

 

Damn I love this site!!!! Thank you Shoebox!!!!!!!!!!!!!!
