Long story, but I helped my friend John haul a 1982 Porsche 911SC out of his mother's garage where it had been for ~10 years. For 3-4 years it has been in a lean to next to John's shop. With the Pinto deal going south I find myself with a hole in the garage, so I offered to put the 911 in my garage to de-mouse and evaluate its condition.
John is enthusiastic! Bless you my brothah. BTW, the official owner died 15 years ago, his rightful heir isn't interested and just moved to Boston. It's been through Probate with no resolution.
Anywho, it's mostly common sense stuff to us, but want to double check for peculiarities in air cooled boxers. Tips?
K jet fuel injection, or efi?
If k jet, remove the fuel tank and filter and pump and sanitize everything, while trying to find a new fuel distributor and injectors, or contemplate updating to an efi engine.
Worst thing in the world for k jet is to sit.
Do you know what's in the fuel tank? In the last few days I've worked on two cars that sat for years. The most significant issue after the battery was that fuel was not flowing. The worst of the two had nearly 1/2" of rust-water-varnish in the bottom of the tank under the old stinky gas. I opened the tank and drained it, then wiped it all out with a sponge. The fuel pump and filter had to be replaced and the lines flushed before it would start. I expect that the injectors are not 100%, but it runs now.
Where have rodents been? Is there poop or nests anywhere? Make sure that the whole intake system is clear and get a look in the ventilation while you're at it. Look at as much of the wiring harness as you can for chewed insulation.
Cool car, that looks like it will be a lot of fun to sort out.
All good questions AAZCD, won't know until it's here. Pulling the tank was on my list anyway.
Thanx.
you'll need to remove the engine tins and clear out mouse nests, leaves, etc, so you don't (1) start a fire or (2) overheat the engine when you do finally get it started.
Fuel concerns aside, I'd plan to pull the spark plugs. Put some light oil in the cylinders, let it sit for a day or 2. Turn it over by hand to make sure it all moves freely and to push excess oil out. Change the oil and all other fluids. Then spin it over with the starter with the plugs still out. That'll push out a bit more excess oil, as well as get the oil pump spinning and build oil pressure with as little load on the bearings, etc. as possible. Once everything checks out up to this point and the fuel system is good to go, put the plugs back and try to start it.
Is there a way to turn the oil pump without startup like in small block Chevies?
pull the plugs , oil it up and let it sit , then turn by hand a little at a time
pull the fuse / relay for the fuel pump so there is no chance of running dirty fuel thru the injectors ,
do not believe the oil level , probably most of the oil drained from the dry sump into the motor ,
once it is turning by hand , you can turn the motor with the starter with the plugs out , this will pump the oil into the dry sump tank.
Good chance that oil is in the exhaust and when its finally started it will smoke like crazy as the oil burns off.
Mine had carbs so I cleaned them out and then cleaned the fuel lines thru the body plus ran a couple of large Ford inline filters ,
Good luck and do not be in a hurry , you do not want to score the cylinder walls.......
I was just going to say, You do not want to score those cylinder walls.
If in doubt, I'd even spend the money to bring in an expert or someone who has done this before. If you hurt the cylinders, you're boned.
My friend of 35+ years has this, will be using his guidance. He was a wrench for Korman Racing before this.
Thanks David.
Given the cost of rebuilding one of these I would pull the motor and go through it very carefully. I think there is a way to pressurize the CIS and then move the air flow plate to get the injectors to fire. The more careful you are the less problems you will find.

Sadly, this did not help the CIS in my GTI.

So we're going to baseline this pooch with a out-of-the-box casting of an ammo box super Victor intake manifold and you've got an 850 carb on it and we're gonna find out what happens before we progress in the port match and fully ported
