DON'T WORRY NO VACUUM QUESTIONS YET

This is an OBD-1 LS swap into DPFI Civic. Pics would make this 10x easier I know sorry.

1) There are 2 short rubber hoses coming out of my speed sensor. Where do they go?

2) There is an open coolant nipple just below the upper radiator hose by the block (it points down & towards the back of the bay). There is also an open nipple just under the throttle body. Do I connect these??

3) Oil breather box on back of block has 2 ports on top. The one is very short and runs up into the block. The other one *I think* is PCV. Where the hell does that hose run??

4) Why the hell are there so many plugs that will fit into the same sensor

 

for question 2 the coolant plug on the back of the engine near the radiator hose is the bleeder valve.

This one is near the front of the engine though....just below the upper radiator hose neck.

I really need to get pics lol

 

In regards to #1, the two hoses sprout from either side of where you hook the speedo cable in.....

 

I read somewhere that the 2 nipples coming out of the speed sensor are for powersteering and add high speed stability to the PS when your traveling at higher speeds. I have always just looped mine and never had an issue. As for the PCV, just loop it all togeathor so eventually it gets to the black box. As for the coolant nipple, we definetly need pics haha. Good luck.

 

That is for "speed assisted power steering.."
{it is actually a small pump}

What most do is to loop a piece of hose and fill it
with power steering fluid to keep it lubricated..
The two hoses are different sizes,I think I used 5/16" hose to join them..

 

^ Very helpful question #1 is now solved!! Thanks

Still not sure on where the PCV line from the breather tank actually ends up.....

OK here's some pics of those (coolant?) nipples I was talking about

Here is the one that's just under the upper radiator hose neck. Hope it's clear enough. It's sticking out at about the 6 o'clock position from the open hose.


I'm wondering if it hooks to this nipple here, under the throttle body.
If it doesn't go there.....it might go where I hooked the red hose up, at the top of the TB. Anyone know for sure what goes where on these ports??


OK next...I have this plug left over from my harness (remember OBD-0 DX ---&gt; OBD-1 MPFI) It's in the vicinity of that same damn upper rad hose, but I can't see where the hell it goes.

Here's what it looks like again: One flat spade-type connector


Thanks again j00 guys rock

 

i think thats the o2 sensor plug

 

Definatley O2 plug.

(Just finished swap too)

 

cool thanks

now i just need PCV routing info, & nipple clarification

what the hell is that red hose coming from the firewall??

 

fuel line

 

hopefully this will help.

the red hose is fuel vapours from the tank. it goes from the firewall to the canister, then the braided line goes from the canister to the top nipple on the TB.

 

here's from a 94+ teg, looks the same.

 

Do you have to put power steering fluid inside of the speed sensor when you loop it?

 

does anybody know if a d16z6 head will bolt onto a d15b2 block?

 

Hey thanks for the helpful responses! According to the diagram those 2 ports do connect. That answers all the original questions....

Forgot to mention I removed the charcoal canister prior to dropping the engine in. Think I remember hearing that you just leave the vent hose hanging and plug the other vacuum ports.....

*off to search*
