VIN #2045 (Bessie) Is Here!
#16
The air box doesn't/shouldn't touch the rocker cover unless it is warped or melted. Any pics of the part?

The air box rests on the inlet manifold , which should not get that hot under normal engine running conditions.
After a long run in mine - you can still comfortably put your hand on it without getting burnt.

tragically, my mobile phone was on charge in the house whilst i was doing the job, and I slapped it all together again just to tidy it away before throwing the kids in the bath for the evening - but I will take it off again and will pop a picture up!

Interesting - that was kind of my thought.  Wonder if this is indicative of an overheating incident at some point in the past..*
Hmm..
Cheers!
 
*perhaps tying in with my 'constantly on fans' issue!  Ooh, it's like being Miss Marple trying to work out the history..!  :-D

I've read differing thoughts on the subject!

This depends on whether or not a PO has put the effort in to try and sort out all the water leaks or not.

There was actually an official factory instructional notice back in the day which highlighted a good few of them, but not all.

Everyone's car is different. I doubt there is a single one out there that doesn't have a leak as there is a fundamental flaw in the design of the doors, which allows water in to soak your carpets if it gets heavy enough, or wet for long enough.

I had 16 leak points in my car. I've fixed them all. Except the doors of course. So my car is a LOT drier than it used to be, but I still avoid leaving it out in the rain wherever I can.

There's only one sure fire way of finding out how yours performs...

Welcome to the DeLorean world! It's like a big jig saw.
When I purchased mine - the previous owner said that he could not manage to "Burp" it correctly and that it kept overheating.
The reality was that the header tank was distorted which did not allow the pressure to build up sufficiently in the engine. Swapped the tank and cap over - then no issues at all!
Then the fans didn't work - which lead to more investigation - to find a dodgy connector near the otterstat!
Really does keep the mind active owning these cars! I love it.

Yep.  Go and visit my family in Wales.  Every single time we go there it chucks it down!  :-D

Yes, I've only had her a fortnight and already I'm spending every spare half hour on her!
Also, my daughters are loving getting involved, so it's great time with them and they're also learning with me.
Plus of course small hands are really useful for access to tricky places!!  :-D

The lower air filter box had actually melted and had holes in it, where it apparently 'rests' on top of the engine block.
I note that DGo have a used one for sale or offer new ones, if it comes to it.
Never seen that before and I have seen a lot of them. Think I have sold all my old filter housings (probably the ones your looking at) you may find one on EBay if you search under Volvo 260/760. Some (not all) had the same filter fitted.

Cool.  At least some more potential options if I muck up my planned repair..!

Never seen that. I took my box off the other day to clean and reoil my K&N filter....finally. I made a point of looking at mine. There's a couple of small blemishes, i'll admit. But nothing like the extent of yours there! At least it's on a "flat spot". Some plate aluminium cut, sealed and pop rivetted into place (or something) into place should fix that ok.

Fix number 1.  I got a bit carried away and tried to go all fancy, with the bolts in the middle of the blue patch there to give a slight enforced clearance from the head.  Unfortunately it was too much and the air box simply wouldn't bolt back up!!
So, the bolts are gone now.
And I'm going to do something more subtle with sheet metal instead.
File under 'seemed like a nice idea at the time..!'

Remember the underside of the ait box practically sits right on the rocker cover when screwed into place properly. There's only a few mm clearance, so any fix will have to be a shallow one. No sticky outy bits.
