88 944S Clutch Replacement Questions

I'm changing the clutch on my '88 944s and am trying to get at the speed and reference sensors.  On this year and model, do I need to remove the air flow meter etc back to the intake manifold?  With the way the intake curves around by the firewall it looks like there isn't any other way.

Also, I'm only seeing a single connector for either the speed or reference sensor (see pic).  Anything else I've seen online has two connectors, an upper and lower.  Where is the other connector located? I guess I'll see when I can reach the speed and ref. sensors on the bell housing.

1991 944S2 Oil Cooler Hoses

I have a 1991 Porsche 944S2 coupe, manual transmission.  The oil pipes/hoses between the oil filter houisng and the oil cooler need to be replaced.  These have been on back order for more than 6 months.  I dont want to install used parts.  Any advice on a source for these oil pipes/hoses?

944 Turbo Timing Belt - While You're In There?

I'll be replacing the timing and balance shaft belts on my 1987 944 turbo this winter. I'll also take the opportunity to change the water pump and varous oil seals. Any other suggestions of things to do while I'm at it? does anyone have a list of required parts? Any suggestions with regards to the special tool required for seting the tension?

944 turbo timing belt

I have a 1986 944 turbo. The car is not driven very much. The mileage is 87,593.

The timing belt was replaced in 4/07 with 82,000 miles. Even though this was 10 years ago, I have only put

5600 miles on the car since then. Should the timing belt be replaced due to the age or because of the low mileage

useage, replacement of the belt is not required. The car is garaged and not driven hard, when driven.

944S Timing Belt Intervals

My wife and I are the proud owners of a beautiful 87 944S which we purchased over a year ago. The car has all service records since new. Since owning the car I have read countless articles/opinions on when to change the timing belts and also the cam tensioner/pads. I would like to get a valid answer on when these components actually need to be changed. We drive the car about 4 times a week and have put about 12k miles on it last year. We live in California so there is no rust or any type of rot on the car.

944 Engine Vibration, Balance Shaft

I bought this car with a persistent engine vibration. The engine has plenty of power, good boost, but there is a buzzy vibration. Previous owner (PO) wasn't forthcoming about the reason he stopped driving it "many years ago". But it seems to have started after the PO had the timing belts and water pump changed 10 years ago. As he hadn't put 1,000 miles on it since the timing belt job was done. I've got the front of the engine apart so I can examine the belts to look for any "obvious" cause of the vibration.

1990 944S2 Warm Start Difficulty

1990 944 S2 Cabriolet will not start when warm.  Starts perfectly when cold and runs beautiful.  As soon as engines warms up, will not warm start.  Engages and shuts down, after continued start attempts will hunt for 15-30 seconds.  With continued attempts, will hunt then all cylinders engage and engine runs perfect.  I believe it may be electronic as all componants effecting the fuel rail have been changed.  New componants:  Fuel pump and check valve; Fuel pressure regulator; Fuel pressure Damper; Fuel Injectors; Engine Temperature sensor; Ignition control module.  Removed the Air Fuel Mon

Looks like I may need to have valve seals replaced.  Does the head need to be removed to accomplish this?
