I noticed today my oil cooler is leaking a little oil. I remember reading that some brands of orings should be avoided. Rockauto has A set from Doorman with gaskets and all 4 orings for $25.79. Anyone know if they are ok?

 

I got mine from advance auto since i work there part time (14.5 years now part time wow). I got victor reinz orings and felpro gaskets and so far so good.

 

Rock auto has the victor reinz for 6 bucks. These are OE. Gs33545

Avoid dorman. Or get the motorcraft ones at the dealer.

 

I have 3 years on Victor Reinz o-rings and felpro gaskets from Rock Auto with no problems.

 

I just got mine off e-bay for about $45 delivered- OEM o-rings and felpro gaskets. Not sure if I got fleeced a bit, but it looks like quality.

 

I wasnt looking really in the right place at RA, didnt see the victor renze option. I will probably go with them and the felpro gaskets. Thanks for all the input.

 

I went with the motorcraft ones and they worked and continue to work perfectly

 

Is there a difference between the 1983 6.9 idi oil coolers I have heard that there are 6 O rings in my 83 but really don't know I can't find anywhere that has them listed?

 

I helped a guy put some on an 86. We went to a diesel shop because the two Ford dealers didn't have them. Got the o-rings and wow...they were $25-26 a piece! They were in motocraft
packs. Tried to get some to match at a rubber and gasket shop. He said that he had some but they wouldn't take the heat and break down prematurely.

 

That's a good question, I seem to recall reading that about the '83s.

And looking at Rock Auto now I see the gasket kits are listed for '83 to '94, but the O-rings only cover '88 to '94; so only the 7.3 on the o-rings. Which doesn't make sense unless they're just avoiding confusion because of the first year 6.9 so they're leaving the entire run of the 6.9 off??

They're just not showing O-Rings at all for any 6.9.

 

Here are the parts number's they're showing on Rock Auto anyway, 7.3L:

FEL-PRO Part # ES70689 Oil Cooler Mounting Set

VICTOR REINZ Part # GS33545 Material: Victo-Tech
Seal

 

If I remember correctly, the man at the diesel shop said that the older ones had more o-rings. Not positive though. The 86 had 4. I have an E series manual and it shows more o-rings.
