ed,

I don't have any fuel gauges. What parts can i do without?

Ed Hughes

I'm not sure there are any parts there you can do without. I'm not expert on CIS, but there are guys here who know their stuff. You may want to start by buying a Bentley manual, if you think this is something you want to tackle yourself. You'll have plenty of support here.

I suggest you have someone with some test gauges troubleshoot your CIS system and fuel pump. It will eliminate some unknowns.

My problem started with a blown air box and vacuum leaks. But turned out to be a faulty Fuel Distributor and Fuel pump check valve.

I'm going to buy the book and have look at also.
Thanks guys

Wow what a mess .... RTV stands for Room Temperature Vucanization and as Ed points out it should be no where near your car. It is lquid that turns to rubber at room temp used for sealing.

is your car a 2.7 ? if it is you could havepulled headstuds also. I noticed the green engine cover so it is not an SC.
You are definitely running lean and looking at the condition of your CIS I think the whole thing need to come off and be inspected and gaskets replaced. As mentioned above it is likely caused by unmetered air entering the sysyem through a cracked airbox, leaking gasket at the runners or some other integrity corruption. Also did you set your CO mixture after doing the changes ? this is imperative.
I would suggest getting a Bentley pulling off the CIS and sitting it on a bench and start working at it if you are mechanically minded . Gaskets are cheap .

On the other hand if this is a 2.7 the first thing I would do is get the valve covers off and check for pulled head studs .... if they are pulle dor missing you are in a world of hurt and it would not surprise me looking at the pics of the engine .. this car looks like it has lacked even basic maintanance for quite a few years .

Good luck .
PS look up my " airbox replacement " thread and it will give you some idea of what is involved .

Theiceman,

As you can tell i really dont know alot about porsche engine's. So here are some more pic's and you can see what i started to work on . I'm trying to find the right book i need for this year engine. Can you tell what year this engine may be by looking at these pic's? Thanks for your help.

Hey Vince,

PM'd ya

Well Vince why don't you start out by telling us the year of the car .. we can go from there ..

vincenttt

The year of this car is 1969. the trans is a 1969 , but the engine is not a 1969 . my father inlaw had it removed and i dont know why. It looks to me that alot of stuff is not in place by looking at the book i do have and on the web. I'm not looking to make this car a show car just a go car. it would be nice to go out on the track some day. I can post more pic's if you would like to see more of this car. I had it out today and no back-fire at all . the RPM's were going up and down and never stayed still. That's why i asked abuot the decel valve and if i needed it on the engine.
my eyes and ears are open . Thanks alot

Edward

Hi Vince,

PM'd you back.

Bottom line is it looks like you have a project in front of you. That yours is a 69 body is great news ...those are beautiful. Rust is your biggest enemy so be diligent with that. As for the engine/drivetrain, you've got to ID what you have, then take it from there. Your hunting idle can be a result of a bunch of things from vacuum leaks to bad hoses to mis-adjusted CIS ...to a whole host of things. Did I mention "project"?
Think of it as a labor of love

Vince look in the back and to the right of the fan housing at the bottom .. their should be an engine serial number on the casing there .. that will tell us your engine type.

Having put in a pop off valve and replacing boots I ewould suggest a baseline Co check .. can you get your hands on a meter to check this ?

vincenttt

theiceman,

the has 6274392 on the right side of the fan.
Thanks

theiceman

well that looks to be a 1977 911s engine. So if i am correct it is a 2.7 litre engine. Others can verify my facts. This engine had a magnesium case and aluminum heds which caused the head studs to pull out of the case. If it has not been repaiared it would be quite extensive and expensive to repair that if they have pulled.
The good news is that if it HAS been repaired before being put in that car it has a lot more pull than the original engine once you get it sorted. If you can get your hands on an LM1 gas analyser I would check your base CO and start there. It may be worth having a competant mechanic at least asses things for you at this point.

vincenttt

theiceman,

Thank you. I will be buying the book that you all have told me about. i dont think anybody would want to work on my car with that RTV stuff on the engine. Do you think i should clean it up a little before i hand it over?

Ed Hughes

If you're going to take it in, I'd not touch anything. Let them go with their own process/procedure/solution. You probably won't get it all off without some disassembly anyway, and may do more damage.
