Back from the dead...

I have a ME engine and I've noticed that there are casting numbers on later-style engines, unlike my previous MK1 engines.  When I removed the piston and rods, I labeled them accordingly.  The order I have labeled does not correspond to the castings.  Below is a breakdown.

My markings.    Vs.     Casting numbers
     1.                                         3
     2.                                         4
     3.                                         1
     4.                                         2

Essentially 1 and 3, 2 and 4 are switched.  I trust my labeling, but I can see some instances where I could've mixed them (however I doubt in such a systematic way).  I have a MK1 bentley, no MK2 so no mention of this.  Sorry to nitpick.

TIA,

Khanh

Make sure you replace the rod bolts - if they have the torque + degrees tightening sequence, they are surely stretch bolts. And if the price is high, I suggest looking around, I typically pay around 20$ for a complete set, and they are FeBi Bilstein made. Also, the 1.9 has different bolts, as do the gas engines (which are again different).
