Oil in SSI...
I'm getting ready to do a heating backdate. After getting my footwell blowers refurbished, it seems that the right HE is blowing that nasty burnt oil smell into the cab.
Looks like the accumulation of a small oil leak over time leaked into the left HE chamber. The engine leak is fixed but can I fix the HE or is it toast?

I think it's impossible to destroy a set of SSI's. Call a radiator shop and see if they can clean the SSI's in one of their cleaning tanks.

Keep the heater valve closed until you burn out the oil - take some some long drives where you keep the engine hot for several hours. Or disconnect the cable at the heater valve on that side and wire the heater valve closed. Then disconnect and remove the hose between the SSI and heater valve and run the car for a while until you burn out the oil, then reconnect.

I just whent through this exact thing.....
I tried looking for the easy way out by calling a transmission shop ( they have steam tanks) they told me it would be a waste of time because its impossible for the water jets to get in there. I also called rad shops and that was a no go also. The conclusion I came to was that there is no miracle tool to go in there and clean it. You cant even see in the middle. Heres what I did. -tape off the lower air inlet and fill it with boiling HOT water.... Let that soak for 10-15min. Then go back for another round and shake it like a maniac. I did this 3-4 times I had a really nasty sludge in mine kinda a mix of dust and oil , this nasty stuff was baked on and almost impossible to get off. I even made a few trips under the cover of darkness to the local car wash  to blast them with hot water. Just to be sure there was nothing left in there I loaded them with VERY small stones ( recomended by a gas tank shop) to again shake like a maniac. Mine are looking new  but it was alot of work.Good luck |

I had a feeling that it wasn't going to be easy, nothing seams to be. I plan to take both HEs off this weekend and start the cleaning process. I think I'll add a little purple degreaser to the boiling water.
I just hope I don't break any exhaust studs.

Yeah... Good luck man.... Just getting the damn heat exchangers off was a nightmare , for me anyway
 I had one stripped allen key nut and it was almost impossible to even get a finger up there . Just be sure to get some new gaskets, allen key nuts x6 , regular nuts x6 and try to keep yourself from going nuts unbolting those damn things  Oh and some antiseize for the next time round
