I have an '80 300TD here. It developed an SLS leak, and the engine will not be started until the leak(s) are repaired. If you run the SLS hydraulic pump low on fluid, damage to the pump is likely.
In your thread regarding the timing chain, don't get embroiled in the timing chain and forget your SLS fluid level, possibly damaging the pump, and giving you another repair that may be unnecessary.
