I have recently stripped a half converted 2.0 ZVH bottom end.

It has what I thought were normal zetec pistons, but on closer inspection they have the mahle logo on the underside on the crown.

Are these normal Zetec pistons?

Please help!

 

No.

They are mahle, probbaly 86mm of Vauxhall origin.

Are they almost flat topped, or dished???

Either way they are forged mahle items.

 

The code of Mahle pistons is usually something of this type: 90V11801.
The letter 'V' means that it's cast, whereas a 'P' would mean that it's forged. The marking on the piston top tell the different sizes and gaps.

 

the pistons are totally flat topped with no markings on the crown. I'm pretty sure they're not the vauxhall ones as I was sure these had a small dish / valve cut-outs.

 

i striped my standard zetec and they were mahle, i think they are
standard for that engine did it have a spacer plate on it

 

no, no spacer plate - looked like a complete bodge to be totally honest! must have been lucky not to blow apart, assuming they are standard!

 

when i stripped my 2ltr zetec (pre 95 engine) to do a zvh, that had mahle pistons, i recon ford use whoever is the cheapest & mahle put in a good bid!

 

i think mahle are the leaders in the piston world as they are fitted to scania trucks in a 9 litre up to 16 litre they are a good piston

 

Yep, Mahle make standard zetec pistons...

 

thanks for the help - best be getting my block bored for the Vauxhall XE one's I have then

 

Why couldnt ford make a N/A engine as good as the C20XE 2ltr 16v vaux lump,wicked engines.
155bhp as standard,stainless tubular manifold as standard,cosworth designed head,early ones had mahle forged pistons and a steel crank as standard and the spread of torque is just wicked!
Shame its a vaux engine.
