Should there be a gasket here?

Between the "breather valve" and the valve cover?


Trying to track down an oil leak. I used silicone last time but I don't think it's doing the job and its still wet in this area

The is only one bolt to hold the breather assembly to the cover.... Which to me means its gonna leak on the other side since its not evenly held in place....

The grooved bit that a o ring fits on is missing/broken off on yours, not sure if the 300 has the same but differant type of housing?

I can get a picture for you once my battery is charged

Delete my last I put my glasses on and see your oring is worn down/gone hard, dig the sucker out and fit a new one

Please do. I think it's broken as well. It looks like the plastic is broken off in an irregular way

Definitely an o-ring for there. If you need a pic of what it is supposed to look like let me know and I can snap a picture.

If anyone finds the correct replacement o ring let me know. I have a box with thousands of nitrile O rings and of course none of them stop this leak, Seemingly one has to buy a new seperator in order to get one that works

Doug, did you try the green A/c ones? I think that is what I used last time.

Nah gave up when nothing in my bag of tricks worked. Truck has been sitting waiting for the replacement injection pump should have addressed this while its down.

I should say the o ring is not really an o ring its a square section, just like the kind you have left over from a full v8 head gasket set. Or at least I allways have them left over.

Bossman don't forget to wash out the Cyclone strainer in nice fresh diesel

I just ordered a new cyclone from RDS. 55 bucks and in stock. Can't beat it.


Still need to wash it out if its new?

An o-ring works fine there. You can see it in the pictures.

So I got the new cyclone and it came with the o ring. I did have one in my old one but it was really squished. I guess I could have just gone and tried to find an o ring to replace it but too late now.

You can see the difference here

not a bad thing to have a spare of. Not like in the truck spare but hanging in the shop spare. I have broken these just leaning on them (they get old and brittle).

You should ask George about injectors. Last I knew he had a killer deal on them. Not a bad thing to have spares of either. Just put some new ones in my 2.5 and it's like a new motor lol.
