Well I can only imagine this work seen below in pics has not been done on the boxes before mounting them to the case. And prior to that someone had used way to much torque on assembly time that resulted in non flat surface as seen in the pics below?
PS. I still have 2 sets of covers available from the last batch (anodised in black), so PM me if you need them.

No change for pricing, not sure how it will look with the next batch.
Prices for the last two sets as follows:
PRICE: $449 for a set with standard mounting hardware (studs OR bolts).
Extra Hardware (studs AND bolts): $20
SHIPMENT: US $20 / UK $20 / Others - ask

Just curious if have any covers available, not concerned about color but still debating a little as I'm actually pretty bummed. I now have leaking covers and boxes (the shop showed me the leaks between the boxes and block as I really didn't believe it) but after spending $15k on a top end job and complete resealing as well as some other while at it things and that was just a few years ago, I'm very disheartened over all of it. It did appear the main leaks are the covers and from what I've read and would love feedback on is changing the covers seems fairly DIY friendly (I've changed the condenser, dropped the motor for the refresh...) but seems like changing the boxes is more than I'd want to get into. Is this valid and how crazy would I be to just put on new covers without dealing with the boxes now? Just an FYI is the shop that did the refresh I trust fully but just seems like he didn't want to propose new housings and covers at the time which is a little odd because we did the valve covers and even the oil pump just as a precaution which my gauge was reading a bit low but was still showed a bit low with the new pump, anyone need a pump?

I do agree. Doing the boxes to towers and to the case is doable, but will include using a lot of bad words during the process.
First you need to remove the boxes and get the surfaces flat as I mentioned above.
Then you need to assemble all with torque book at hand not to overtighten the boxes as they will leak again (people think if they torque more, leaking will stop - it’s the opposite).
And then you’re left with setting the timing or at least verifying the timing is right (as you need to remove the sprockets from the cams to remove the boxes).
Doing covers is peanuts, but boxes… I’d say you need the proper tools, skills and a spare weekend.

If you work carefully and make sure the chains don‘t slip and are replaced at exactly the same position, the timing doesn‘t need to be reset. Worked fine for me.
P.S.: fully agree to the cursing as Konrad said 😊

Thanks all, I know it probably sounds bad to not set out to tackle all the leaks (box to case and box to cover) but the thought is if replacing the covers is much much easier (easy weekend job) than the boxes (3 weekends and lose skin, blood, sanity) that probably takes me from and of course just a guess, 10 drops a month to 1 or 2 and then wait for when have more time and patience, and maybe get a lift installed which also hinges on the time factor, then tackle the boxes. Is it really crazy thinking? To me it's probably the difference between breaking the big pan out that used to keep under the car and having to put it back under where a few drops is an easy wiping.
So Konrad and first, thanks for all your time on the covers and this thread... my car has fortunately been very trouble free for a long time now (knock on wood) so haven't been here much but it is such a great resource and drives me a bit crazy folks bringing tech questions into the FB groups, just pop over to rennlist... I contribute A LOT on construction forums which it's nice we can all share knowledge! So anyways, you made a comment that jumped out at me, if I'm doing this with motor in and not doing the boxes, is it really possible if the surfaces aren't flat to get them flat which of course is necessary with your and I would guess pretty much any cover? If there's a big concern about not being perfectly flat should I head in a different direction?

That’s why they are re-engineered - to solve completely at least one point where sooner or later all our cars will leak.
