As you can tell the filter house is not the right one for this installation but that will get replaced soon enough.
Also all of the D16Y7 engines I have seen online had an intake manifold with the intake port coming staright out of the top.
Leads me to think maybe this IM is from the original engine that was in this car.

Thanks, for the help.

 

Alright, so you've got a 96 EX with a y7 motor in it? What year is the y7 from?

You are correct, that is a y8 intake manifold, probably the one that was on the original motor. If you can, I would talk to the previous owner and find out for sure where that Intake Manifold came from.

The first thing I see right off the bat is that you're missing your Coolant Bleed Screw, which means there is probably a fair amount of air in the coolant system. Open your picture, and the one below, notice where the Upper Radiator hose meets the motor. On yours, there is just a hole on top, on mine, there is a little triangular shaped bleed screw. You need one of those

Also, Chances are when you get on it, you're prbably shooting coolant out of the hole. Are you losing coolant? Check and double check. You'll also need to bleed the system to make sure there is no more air in there.

Next, unless you see a port/nipple on the air intake assembly where that hose from the valve cover should connect, just remove the hose completely and put a breather on there. (Autozone, 8 bucks)


Start with those things.Once you've got all your vac lines connected (cruise, etc..), and the coolant is bled and filled, if you still have surging issues we will go from there.

 

good call.....i wouldnt have noticed that little bleed screw missing...but will air in the coolent really effect the idel any?

 

Yea I had a very similiar problem, it was the FITV.

 

Just got in from a very long day at work.[:@]

I have never noticed that screw missing. I haven't noticed any coolant anywhere, and the car runs cool. But I have not checked closely. I will get to work on these things in the morning.

Also, I have spoke with the guy I bought this car from and he doesn't seem to know much about the engine or chooses not to reveal. He said it was his nephew's car.

What is the best way to bleed the coolant?

Thanks for the help.

 

I knew you were going to ask that, now I gotta do a DIY I'll post the link up in a little bit.

You have to have that bleed screw though, so hit the Honda Dealer and pick one up. If you don't need the car on the road within the next couple days, I can mail you one as I have an extra off my old block. Let me know..

If you start the car up, take a look at where that screw is supposed to be, and rev the car a little. It should shoot coolant out the hole. Not a ton, but enough to create a dangerous leak.

I'll start writing the DIY Coolant Bleed here in a minute

 

OK, I just took a look at it. Mine must be different. There are no threads in this hole and it is sealed off at the bottom of the hole. So no coolant is coming out there. And my coolant level is at the max in both the radiator and the overflow resevoir.

 

wtf, no kidding?

Hmm, check out the t-stat itself, you have to have a bleeder valve on that car somewhere

 

Thermostat seems to working as it should. And I was unable to locate any other place to bleed the coolant.

I started reading in my Haynes book and noticed the the idle speed for this engine should be about 670, but my engine is idleing at 1500. So I backed the Idle speed screw out a little and now it does not die when the cruise is connected.
Since I do not have a tach other then the one in the dash, I can only guesstimate 670.
The engine seems to idle slightly on the rough side (a little bit of vibration) but it does not stall.

 

Well, the problem with just turning the idle screw is that it's not fixing anything. Idle screws have been known to back out, but certainly not in an "all of a sudden" manner, and to this extreme.

Did you set the idle according to the manual, or did you just start turning the screw? There is a direct procedure to follow when setting idle.
