what method do you use for the high pressure front cover junction? henry @ mazdatrix recommended using just the teflon ring on an S5 housing, with no gasket and RTV.



I tried teflon ring plus the O ring, and no gasket w/RTV and when I went to remove the front cover becuase it had a stripped oil pan hole (replacing cover).... I discovered the O ring had caved in to form a pac man shape with just a small mouth. I thought maybe I had used the wrong O ring but there are no smaller rings in my gasket set, and it fit snugly in the teflon ring. I will be using just the teflon ring now as per mazdatrix suggestion.



What's your method?

 

I use hylomar to hold it in place

 

The new gasket here in Japan on the 99+ FD is metal and you only use the teflon o-ring.. The gasket can also be reused so you don't have to buy a new one after every overhaul, and you don't have to spend 30 min + trying to get the old gasket scraped off of the front cover etc..



the part # is: N390-10-502 and it cost around $20

 

to hold what in place? The O ring or the teflon ring? what setup do you use? (gasket? O ring? teflon? ...)



sorry to be a pain but the details would be useful

 

Hey dragon, can you get us some of those?

 

I could, but you should be able to order them from mazda in the states with that part #...
