Reviving a 71 911T

[Bert87]

I've been reading this forum quite a bit, and finally made an account.

My dad's 71 with a 3.2 from an 88 has been sitting in the garage for a while after an apparent leak of some sort. Apparently, the leak was sudden and quite large resulting in a large pool in the garage when he went to leave for work. I've gradually added oil without any leaks, so the next step is to get this thing running so I can further check for leaks. I have put together a list of parts I believe need to be done to attempt an initial and brief start to further search for leaks.

Fuel Lines
Fuel Filter
Injector cleaning and inspection
Oil Filter
Oil drain crush washers
Fuse Kit
Spark Plugs
Brake Lines (bulging present)
Air Filter

After identifying any leaks I will then replace the oil hoses and maybe a few more seals. Test drive it very carefully around the block, and go from there. Anything missing? Also, I plan on replacing the fuel pump with the 88 part, would it be smart to relocate the pump to the front? It is currently mounted near driver's side rear torsion tube.

Here it is in its current state, I will be returning the blacked out bits to their original state once it is running.



Thanks everyone for your help, reading this forum has been a joy!

How long is a while?
You may need to drain fuel tank and don't neglect the braking system either!

FYI, there are rubber fuel lines that connect the hard lines just forward of the rear wheel arch in where a trans tunnel would be. Over time, those will leak. They are only a few cm long and a bear to wrench into place.

Ask me how I know...

Be careful when adding oil. Checking the oil level using the dipstick must be done when the engine is warm and running at idle. If you check the oil level using the dipstick with the engine off, it will be overfilled.
The fuel lines on the engine could need replacing. One of Peicans members. BoxsterGT or Len, offers a nice replacement set.

I would carefully check the oil line that goes from the bottom side of the engine case to the oil tank. They are rubber on a '71 and can wear through over time. AHIK. That oil hose will run over the trans and down by the tank. It will probably have that hose unless whoever did the 3,2 upgrade changed the transmission and oil tank to the newer style or kept the 3,2 exhaust.

About 10 years! Fuel tank has been drained, cleaned, and drained again. The 'drain' proved to be not that nice of a drain!

I have already replaced all the fuel lines ahead of the fuel filter, although, it sounds like my car might be setup a little differently. There are very short lines (fuel supply and return) running from the tank to the hard lines in the body, then lines coming off the hard tubes in the rear, curling up around the body to the fuel pump. But these are a few feet long. Or are you talking about the lines going from the pump to the short hard tubes to the filter?

When I change out the fuel pump I will most likely relocate it in the front and totally redo the fuel lines as the 88 parts are somewhat spliced into those of the 71.

Yes, after checking for leaks I completely drained the oil and put in 8 quarts. And I have seen Lens work, it is very nice. I believe I have found a shop where the car is, or if that fails I have heard Mesa Hose down here in San Diego has done these assemblies a few times.

Yes, I will be replacing this line if it is the one I am thinking of. Comes out the very bottom of the tank then runs perpendicular into the case? On my car it is part rubber on the end that connects to the oil tank. The crimps fail the spin test. I do need to do some deeper research into finding out what parts of the oil system belong to each year, hopefully the manual I ordered will help me in that.



Thank you everyone for the advice, it is getting quite exciting!

If you post some pictures of the bottom side of the motor and remove the rear passenger tire to show the oil tank, we will know what setup you have.

There are different ways to adapt the 3,2 motor's oil lines the original oil tank. If indeed you still have the original oil tank.

What transmission do you have? The original '71?

Is there a front oil cooler?

[Trackrash]

This is the hose I was referring too. Not sure if this is what you have, but this is the original '71 setup.

[BoxsterGT]

This looks familiar.

My car is a 69 so may be slightly different. These are the lines I'm referencing. Forward of throttle linkage on left side rear. They connect hard lines coming from tunnel and engine bay. Just take a look for safety's sake. I had no idea they were there until a guy at the gas station said I was dumping fuel.

The transmission is original I believe, has the appropriate I-H shift pattern. Also has '911/01 7710469' stamped on the case.

There was a front oil cooler, but the lines going into the body from the tank area have been cut. It has the engine mounted cooler from the '88 I believe. I will get so more pictures next time I can get to the car, it's about 6 hours away. Your picture of the '71 looks like a slightly different hose setup than what I remember.

The fuel lines coming from the body hard lines are several feet, and the fuel supply line going to the pump is larger. Where is your fuel pump located?

When I began jacking up the front of the car to drain the gas tank fuel started running out from the hose connected to the hard line, I have already replaced that portion.


This car is sitting on 225/60 tires and 14x5.5 fuchs. This seems a bit unusual?

And I also believe an aftermarket AC was installed into the smuggler's box area, although my dad (who drove the car for 10 years) insists it does not have AC. I'll see if I can get some pictures of it.

So, what have you fixed and are you driving it yet?
