Piston Projection, Measuring At TDC: Procedure
WARNING: This page is about a different car, the 2015 Volkswagen Golf. However, it is still accessible from the selected car via links, so may be relevant.
-- Secure the :VAS6079 with the :VW382/7 and :VW385/17 to the cylinder block, as shown.
-- Measure the projecting end on each piston at both spots identified with -arrows- (longitudinally on the engine: at the front and back of the piston).
-- Depending on the piston projection, install the corresponding cylinder head gasket according to the following table:
| Piston Projection above the Upper Edge of the Cylinder Block mm | Identification Holes |
|---|---|
| 0.91 to 1.00 | 1 |
| 1.01 to 1.10 | 2 |
| 1.11 to 1.20 | 3 |
