Working car engine, Blend file and anim.

This is still unfinished, but it has the animation in place for pistons moving on the end of con rods, moved by a camshaft.

I have seen a few posts asking how trhis is done, so here is a small 242kb divx5 anim and the 88KB zip file containing the .blend.

I hope this is useful to somebody.

I used parenting and track To constraints, no armatures, just Key frames for the camshaft rotation.

Blendfile at the end of this link, 88KB zipfile.

Could do a tutorial if this method works for you guys.
