Ok, now I get it.There is an oil cooler in the housing behind the oil filters, all this has to be removed ………and replaced with new gaskets & bolts, to get to the gasket between the engine block and oil cooler, I’ve got a pdf of the parts but can’t load it on here.
When in post #2400 you said "It’s not the filters, it’s the block that the filters are bolted on to", I assumed that the leak was in between the assembly supporting the filters and the oil cooler behind it.
In other words, that the seal to be replaced was the one visible in the second pic below, after removing the filters support.
If the leak is in between the oil cooler and the block, I appreciate that the job is more tricky.
£6k still seems a bit steep to me, but I'm not the one who does that for a living.
I'd be in doubt about doing the job also on the non-leaking engine though, considering that leaving it alone means halving this costs, I suppose?
After all, there's no mention of replacing that seal in any MAN scheduled maintenance, neither in terms of time nor hours.
So it's a bit of a stretch to assume that the other seal is likely to fail soon just because it did on the other side.
Apropos, how many hours have your engines clocked?
