ABF 16V Oil cooler heat exchanger housing cleaned and ready to fit.

All 3 of my engines (2no. abf and one diesel) did not have any gasket there.
Ally bracket/housing straight to ally block.

For my own piece of mind I did put a smear of silicon on it.

Only seal I have used in that expanded view is 19

i don't remember there being 1 tbh but a lot of work for a leak if i dont put one on.

[Len]

As I said none of the 3 engines had a gasket and there were no leaks!

It should have a gasket between block and housing, might be worth fitting a new exchanger as well at this stage.

i have a good used one from last engine has no leaks and im replacing both seals to ensure no leaks as well.

The gasket has been present on all the VW/Audi passenger and industrial engines I have worked on That use the same housing and should be a single layer (possibly stainless) spring steel one. Because it usually sticks to the block not the housing it can be missed.

The only reason I can see a gasket is needed is due to the possibility of the housing warping and not sealing against the steel block.

Spot on, only real reason it is needed tbh.
