All-Do we have the part number for the metal rings/donuts that fit between 

the intake/exhaust stacks and the back if the cylinder heads?

I can't find it in the parts catalogs...

???

Thanks--

I am sure there are part numbers.   But I have purchased those from Doug and Richard.  

The exhaust are called exhaust donuts in the US.  

I think, correct me if I am wrong across the pond they call them exhaust olive gaskets.   

The seals for the intake side are paper from the factory.  There is an upgrade to a red viton Oring seal that I installed 2 years ago.  Zero problems since then.  I completely cleaned out the gasket channel and installed two of the new paper gaskets then the viton ORing.   It seals perfectly. I took one of the orings out this last condition inspection and the paper gaskets were still clean and like new.  No oil seepage around the Oring. 

I am sure Doug has all of this stuff.  I am running an M14P on my CJ.  The parts could be the same.  

Reach out to Doug and Richard if need be.

Yes, in Europe we call them exhaust "olives". The standard size is 10 mm thickness, but we realised that a certain number of people fail to tighten the exhaust nuts on a regular basis; the exhaust plus olive then "fret" against the cylinder head and wear it away, and in these cases we manufacture thick olives to any size people might want. So the standard olives are Euro 28 each and the thicker ones in any dimension (to order, since we manufacture them) are Euro 38 each.

 

And the intake tube gaskets are of course different – it is a rubber ring at the supercharger end, for which we charge Euro 4 per ring and at the cylinder end it is a paper gasket, but in order to get the appropriate thickness one needs three of them per intake tube. Cost is Euro 2 per gasket, so Euro 6 for the three and so a total of Euro 10 per intake tube!

 

All are in stock with Aerometal in Hungary, so let us know if anyone needs them.

Great info all, thanks-I learn something every time I open the cowls.

Thought there were olives/rings on both intakes & exhausts, good to know just exhaust stacks and fewer req'd.

I'm running a Chinese Housai, any info on those ring p/n's?

Thanks again- Justin

 The exhaust seals are identical for both the HS and M14  engines.   

  

 There are stainless steel units manufactured by one of the US exhaust  manufacturers.  I have those on my engine but would caution any one  considering same to be aware of the fact that as theses units are pressed in  manufacture they leave a sharp protruding edge that will destroy the aluminum  alloy cylinder seat.

  

 If they are perfectly centered  they will work however I have yet to  see an exhaust system made to perfectly align with all of the cylinder  seats.

  

 I have modified these for my own use but it is an extremely dangerous hand  grinding operation.

Walt.  

I just had this education recently from Richard.  

They make the exhaust olives in three thickness. 

10, 12 and 14mm to help fit the flanges better.  

Since I used these my exhaust fits very well and stays tight.  Grinding those would be difficult at best.  

I have attached a photo of what Richard supplies.  I understand Richard uses these on a regular basis 

On his side of the pond

Yes, in Europe we    call them exhaust "olives". The standard size is 10 mm thickness, but we    realised that a certain number of people fail to tighten the exhaust nuts on a    regular basis; the exhaust plus olive then "fret" against the cylinder head    and wear it away, and in these cases we manufacture thick olives to any size    people might want. So the standard olives are Euro 28 each and the thicker    ones in any dimension (to order, since we manufacture them) are Euro 38    each.   

    

And the intake    tube gaskets are of course different – it is a rubber ring at the supercharger    end, for which we charge Euro 4 per ring and at the cylinder end it is a paper    gasket, but in order to get the appropriate thickness one needs three of them    per intake tube. Cost is Euro 2 per gasket, so Euro 6 for the three and so a    total of Euro 10 per intake tube!   

    

All are in stock    with Aerometal in Hungary, so let us know if anyone needs    them.

I am sure there are part    numbers.   But I have purchased those from Doug and Richard.     

      

 

      

The exhaust are called exhaust donuts in    the US.  

      

I think, correct me if I am wrong across    the pond they call them exhaust olive gaskets.      

      

 

      

The seals for the intake side are paper    from the factory.  There is an upgrade to a red viton Oring seal that I    installed 2 years ago.  Zero problems since then.  I completely    cleaned out the gasket channel and installed two of the new paper gaskets then    the viton ORing.   It seals perfectly. I took one of the orings out    this last condition inspection and the paper gaskets were still clean and like    new.  No oil seepage around the Oring. 

      

 

      

I am sure Doug has all of this    stuff.  I am running an M14P on my CJ.  The parts could be the    same.  

      

 

      

Reach out to Doug and Richard if need    be.

All-          

Do we have the part number for                     

the metal rings/donuts that fit between      

          

the intake/exhaust stacks and the back      if the cylinder heads?

          

I can't find it in the parts      catalogs...

          

???

Walt.  

I just had this education recently from Richard.  

They make the exhaust olives in three thickness. 

10, 12 and 14mm to help fit the flanges better.  

Since I used these my exhaust fits very well and stays tight.  Grinding those would be difficult at best.  

I have attached a photo of what Richard supplies.  I understand Richard uses these on a regular basis 

On his side of the pond

		      Hi Justin:

    

 The exhaust seals are identical for both the HS and M14  engines.   

  

 There are stainless steel units manufactured by one of the US exhaust  manufacturers.  I have those on my engine but would caution any one  considering same to be aware of the fact that as theses units are pressed in  manufacture they leave a sharp protruding edge that will destroy the aluminum  alloy cylinder seat.

  

 If they are perfectly centered  they will work however I have yet to  see an exhaust system made to perfectly align with all of the cylinder  seats.

  

 I have modified these for my own use but it is an extremely dangerous hand  grinding operation.

  Great info all, thanks-  I learn something every time I open the cowls.

 Thought there were olives/rings on both intakes &  exhausts, good to know just exhaust stacks and fewer req'd.

  

 I'm running a Chinese Housai, any info on those ring p/n's?

  

 Thanks again- Justin
