Hey everyone. The yellow '74 914 arrived on the truck today. I met the guy at the mall. I'll post another posting about the fiasco of getting the car off the truck.

Problem:
Start the car and it idles at or above 3000 rpm. There was one or two hoses that looked to go into the air box that were not connected them. I reconnected them but that did not help.
There is a hole on the drivers side on the engine block that does not have any hoses connected.

The air box to throttle body does not seat all the way down. I tried to press it down but it would not stay.


I left the car at the mall as I am afraid to drive the car around with it idling so high. I did a couple circles in first and second gear.

Please help!! I do not have a haynes manual yet as I did not expect to have any problems the very first day that it arrived.

Argh!!! The wiring is definately a hack job.

I'll post pictures later with circles around the various parts. I just got home and I am trying to relax. Very bad day.

We my very first 914 and the first immediate problem.

It probably bounced around so much on the transport that it yanked the air filter off the engine along with all the hoses.

This is an easy fix.

Print these pics off and take a cell phone with you.

That has to be a vaccum leak. Must have popped a hose off during transport. I would go back and check EVERY hose, for cracks and being weather they are connected or not. If there is a hose missing from what sounds like the head breather port then there is probably a missing connection to the air cleaner, which would give you this high of an idle.

Any of the hoses leading to this plenum will cause a 3k RPM idle.

The main one that is probably OFF is this one that goes to the OIL FILLER from the intake manifold. Plug it back in.

Dont worry about the one in the head right now. Just make it run.

Beyond that, check to make sure the throttle return spring exists.

oh... and is returning.

Brad, is this the oil breather?

That is it. See the fitting without the hose ? That hose goes directly to the intake plenum. BIG LEAK.

I see Mikey made no attempt to clean the engine up.

1) Completely disconnected. Goes to the driver's side to a T splitter. Then to the engine (I think. No good pictures )

2) It was connected but it is loose.

3) Electrical tape is around this. Barely stays on. I'm not sure if it is sealed. Came off with out any effort. So I stuck it back in.

4) Thottle body is disconnected from air intake. I tried to slip this on but it will not stay nore will it go on all the way.

More pics. (http://www.my914.net/Porsche/my914/Vacuum%20leak/)

I can see a red line that is just "back" of the fitting. Put it on. If the proper hose was used.. it wouldnt have fallen off.


B

Posted by: eldiosyeldiablo Jan 3 2004, 07:29 PM

Anyone have a clear pic of how most of these hoses are suppose to go? Oil breather tube?

I'll check out pelican's site.
Trying to download from the 914world.com/downloads/ site right now. Brad, do you have a zip file out there rather than all the individual files for the tech manual?

-David

Posted by: echocanyons Jan 3 2004, 07:29 PM

Check and make sure the accel pedal isnt sticking on the carpet or something

Posted by: eldiosyeldiablo Jan 3 2004, 07:30 PM

Red line? I don't see it.

Thx for the quick responses guys. Man you guys are quick.

Posted by: Brad Roberts Jan 3 2004, 07:30 PM

First order of business. BUY all the correct size lines (metric sized) They used Merican lines that dont fit metric fittings. It will run you 50-60 to redo all the breather lines. Buy the cloth braided style.


b

Posted by: Brad Roberts Jan 3 2004, 07:31 PM

NONE of the lines should have hose clamps on them.


B

Posted by: eldiosyeldiablo Jan 3 2004, 07:31 PM

Pedal is all the way up. It sticks a little but I have pulled it all the way up and started the car when I was there and it did not change it.

Posted by: Brad Roberts Jan 3 2004, 07:37 PM

This FUCKING HEATER HOSE for a TRUCK should be on that fitting.

I lied. That HOSE is on the AAR.

B

Posted by: Brad Roberts Jan 3 2004, 07:39 PM

The single zip is too big for all the files it takes 30 minutes to download even with high speed.


B

Posted by: Brad Roberts Jan 3 2004, 07:42 PM

No.3 in your pic above needs to go to the oil breather fitting (which is it way to big).

Where is a ZOIS ?? Unless you put that hose on the air cleaner... it NEVER ran correctly.

B

Posted by: Brad Roberts Jan 3 2004, 07:43 PM

No thermal time switch.. wire hanging there ready to ground itself and fire the cold start injector.


B

Posted by: Brad Roberts Jan 3 2004, 07:44 PM

It needs a new throttle cable. Somebody overtightened the original housing and it broke... they used a friggin hose clamp to hold the cabe to the plenum...


B

Posted by: Brad Roberts Jan 3 2004, 07:48 PM

Shouldnt be any hose clamps on the intake plenum from the runners. Buy new connectors.

Chat with Bowlsby about a new wiring harness.. that one is shit.


B

Posted by: Brad Roberts Jan 3 2004, 07:56 PM

The junction for the breather lines (from the heads) should sit (screwed down) to the fan shroud just to the left of the breather (from passenger side pic).

This thing... right now it is sitting behind the air cleaner near the top of the fuel pressure regulator.

The two "legs" on the bottom receive hoses from the heads. The top one goes into the air cleaner.

David,

Don't get freaked out by Brad's picking. He's got a good eye and I've seen him do this in person several times. Unsuspecting folks will ask him to look at something and it just starts coming, and coming. He'll notice everything odd-ball.

Don't let it freak you out though, just make a list.

Posted by: Brad Roberts Jan 3 2004, 08:10 PM

I want the cars right. The cars have a bad wrap with most people and it is because most people dont take care of them. This one was hacked together by some home user with crap from Pep Boys. It pisses me off. It really irks me when a fellow 914 person sells cars and doesnt make any attempt to fix this little crap.


B

Posted by: eldiosyeldiablo Jan 3 2004, 08:53 PM

Too many responsess!!!!

First. Are #1 and 2 hooked up to the correct locations?

Posted by: Brad Roberts Jan 3 2004, 08:57 PM

NO.

No.2 should go to the oil filler.. go ahead and read the posts.

Posted by: ChrisReale Jan 3 2004, 09:15 PM

My eyes could be deceiving me, but it looks like the air box at the throttle body is broken...??? #4 in the pics above.

Posted by: eldiosyeldiablo Jan 3 2004, 09:19 PM

Chris,

The top of the throttle body has a rubber fitting on it that seems to slip on the inside of the air box but I could not get it all the way down nor could I get it to stay.

How does it stay? Is there suppose to be a clamp on the top part like the lower part?

-David

Posted by: ChrisReale Jan 3 2004, 09:22 PM

Yes, there is a clamp, which has the screw that is fixed to the throttle body. It should be on the air box. maybe it just came apart, but it looks suspitious to me..

Posted by: redshift Jan 3 2004, 09:25 PM

Take the airbox out buddy, look on the sides (front-back actually) at the bottom clamps hanging down...

The one toward the trunk needs to be in place first, they get caught on the lid spring things, and/or in front of the plate they clamp to..

If they don't hold it down well, bend them til they do.

the hose diagram at the pelican tech article area shows the whole works. print that. i did it for my 1.8. it's super.

Posted by: Brad Roberts Jan 4 2004, 04:38 AM

Once the air cleaner comes out of the rubber grommet.. you have to pull the whole assembly off the car and press the rubber piece with the clamp back into the air cleaner. It presses in with some minor force. The reinstall the air cleaner.

I had a buddy that did that...........car was gone the next morning, never found it!!!!!!!!!!!!! git that car to your house fast!

David:
Don't worry man, you're in good hands.
These guys (esp. Brad) really know their shit when it comes to these cars.
Bookmark this page and check it out often.
I'm not sure where I'd be without all the help I've received from the guys on this board over the lat few months. They are always willing to go the extra mile to help a 914 guy out (even if he is from WI).
Good luck with the 914.
Andy...
P.S. Sorry no tech support, just moral support....

Here study this pic of the hose layout.

David, while you are in there...

Replace all the rubber fuel lines, clean up the electrical grounds, and replace ALL fuses. This engine bay looks like it fits well into the 'deferred maintenance' category. Clean it up and it should be fine.

Check all the wiring harnesses for brittle, broken wire insulation and main harness casing, corroded wire terminals and missing boots. Post photos of any questionable wiring issues. Your alternator harness is coming through the engine tin hole for the drivers side heater J-tube...the grommet on the alternator harness should go through the smaller hole aft of the J-tube hole.

Welcome to 914 owner-dom...

Posted by: redshift Jan 4 2004, 01:52 PM

Momentary threadjack:

Jeff (if you see this again)

What would you substitute as a CHT connect on the harness? I don't like that thing getting hot, and floppy.


M

Posted by: 72914S Jan 4 2004, 02:09 PM

Looks like there are two throttle body to breather grommets? at least my car only has one.

Posted by: eldiosyeldiablo Jan 4 2004, 02:17 PM

The car is home now. Just need to put it in the garage.

The main problem was that oil breather hose. Now it idles at 1000 when cold and 1500 warm.

I will have to take pictures and show them to everyone.

Feeling with my fingers I found a fist sized hole on both the driver and passenger side for the hell hole areas.
Pin holes on driver's side engine wall.
Both water shoots(tunnels) have holes in them.

This is not looking good.

Positive note. Engine pulls strong and tranny seems fine. Little finicky about 1st gear from a complete stop but not bad.

-David

Posted by: Jeff Bowlsby Jan 4 2004, 03:13 PM

It has a long rectangular plastic housing that protects the TS2 from grounding out....did I understand your question???

Posted by: redshift Jan 4 2004, 03:20 PM

Yes, on this current car, it's one of the brown ones, and I hadn't noticed before troubleshooting the CHT, it is very VERY pliable when hot, and I was just wondering if you even reuse those.

I think my problem actually lies in the connector, not the sensor, which I cannot get to fail on a tester.


M

Posted by: Jeff Bowlsby Jan 4 2004, 03:27 PM

There is a 'long-blade' male wire terminal on the harness and a standard 25mm female on the CHT. Just pull the two wire apart and replace the wire terminals if needed. GOod electrical contact is important here.

I have a stash of the brown housings, but typcially repalce them with a new OEM housing becasue I can get those new. That area of the engine bay shouldnt really get that hot unless its touching the engine case.

Posted by: ChrisReale Jan 4 2004, 03:48 PM

Those fist sized holes are probably the heater holes for the J-Tubes. That is , unless they are jagged rusty gaping holes...

Posted by: eldiosyeldiablo Jan 4 2004, 08:13 PM

Not sure yet. Just got the car. I have to go back over to my neighbors to steal my drop light back.

Ok end of thread. Time to order my Hayes book

Posted by: Bleyseng Jan 4 2004, 08:31 PM

Don't bother, just download the shop manuals from this site. Waaay better info

Glad to hear you got the car home! That has to feel good. I had a worse experience getting mine home. I was planning on driving it 2hrs to get home, until 20 min into the drive, the clutch went out. That sucked. So a hose isn't so bad .
