993 Engine Drop: Prework


After reading others' experiences, I realized I would have to upgrade my 993 jacking and jack stand procedure for the engine drop.  The engine drop requires a lot of clearance at the rear!

The first step was to buy 4 Esco flat-top jack stands.  (I've been eyeing these for years, and finally found justification!)

There are two common approaches to raising your 993 on to jack stands: the teeter-totter method and the "cactus" method.  So far I've been using the teeter-totter method, but to obtain the necessary height for the Esco stands at max, I went with a hybrid approach.  I would have used the cactus method alone, but I had limited space in front of the car.
  1. Roll rear on to 2x12 planks (probably not necessary with low-height floor jack)
  2. Chock driver side wheels
  3. Jack under passenger rear until Esco at min height fits under passenger front jack point.
  4. Chock passenger side rear wheel
  5. Jack under driver rear until Esco at min height fits under driver front jack point.
  6. Jack under engine and place both rear jack stands at min height
  7. Place board under the front of the car and jack the car until two front jack stands can be placed at max height
  8. Jack engine until two rear jack stands can be placed at full height.



Next time, I will probably modify the sequence to:
  1. Roll rear on to 2x12 planks (probably not necessary with low-height floor jack)
  2. Chock driver side wheels
  3. Jack under passenger rear until Esco at min height fits under passenger front jack point.
  4. Chock passenger side rear wheel
  5. Jack under driver rear until Esco at min height fits under driver front jack point.
  6. Jack under engine and place both rear jack stands at medium height
  7. Place board under the front of the car and jack the car until two front jack stands can be placed at max height
  8. Jack engine until two rear jack stands can be placed at full height.
