Piston to Head Clearance

[turboman1]

What is the minimum piston to head clearance? I am around 0.038", is this enough?

Piston protrusion from the surface of the block is 0.024" and I have a .010" thicker than stock head gasket.

12 Valve Motor.

Thanks

Piston protrusion .024-.028 hg .060 looks like .035

 

[cumminslow]

cummins calls for .028 to be max

 

[DISTURBED]

you mean min.

 

[cumminslow]

no it says max is .028

 

[DISTURBED]

And were are you finding this?

 

[cumminslow]

cummins service book

 

[DISTURBED]

I would use .028 as min. no matter what the book says

I would use .028 as min. no matter what the book says

I'm pretty sure he's referring the .028 for piston protrusion maximum.

 

[cumminslow]

what is the reason of specs than?

 

[cumminslow]

yes that is correct piston pertrusion max is 028

 

[DISTURBED]

Sorry i thought you were talking piston to head. Since the renopker said .035

 

[Diehard Ram]

What is a safe number between the head and piston. Min -Max. No one said.

 

[DISTURBED]

No closer then .030
