Whilst luxuriating in the Conservatory of Chez CDMonte and admiring all that I own, knowing it’ll need mowing, cutting back and cleaning. The Fence I did last year with concrete posts and new panels leading to a crucified back and left hip. Suddenly a loud bang from above made me jump spilling coffee over my lap and fast exit to bathroom to cool down jewellery.
Coming back down iinitially I couldn’t see anything out of order until I got to panel 3 of the polycarbonate roof to see a hole, looking around on the lawn I saw an AA Battery, I fixed the hole at which point Mrs CDMonte said how about we change the roof to one of these highly insulated and tiled roofs.
So, we asked a number of different roof installers to come and quote of which only one made any sense but it would require change of the Double glazing units and doors we have as like the roof they are 20 years old and a heavier roof may have an adverse affect on them..
Bugger thought I, that’s the budget shot, when we received the quote it was more than the first house I ever bought. So, a cheap AA Battery is going to cost me a load of dosh, the pay off is it will give us another room we can use all year round.
MrsCDMonte has stated the Honda will not be parked in it.

Our conservatory was a Mahogany framed one built in 1987 across the back of our house that was 120F in the summer & -10 F in the winter so we bit the bullett about 7 years ago replacing it with what they called a Warm Roof design - a couple of Velux windows in the roof with two layers of 2" Kingspan type insulation & a plastered ceiling etc. All new spec double glazing.
It cost us £18,540 in 2015 using the existing base - I've installed radiators off our existing central heating system we use the room all the year round. Made me gulp when I first had the quote as our first house was only £10,250 in 1978. Fortunately I had an unexpected lump sum due to a commutation error when I retired to soften the blow.

Hi Ted,
Ours faces North so it doesn’t hit the 120 degrees in summer but winter does hit pretty hard even though we have a radiator out there. Sounds like yours is pretty much the same as ours, it started as 8’x10’ but swiftly migrated to 10’x22’. It has a brick bottom half with double door in the middle so really could be called a summer lounge. I think having seen your reply we’ll go for the change even though the budget has been well and truly shot.
I’m leaving the fitting to the experts as having recently put an outside composite door into the kitchen I think I hit my zenith, plus Mrs CDMonte gave me that look that any husband knows is tantamount to ‘Don’t even bother unless you want a resting position UNDER the patio’
-
My brother just had insulated panels fitted into where the Polycarbonate sheets were I think it cost him around £8k in 2020 keeping his old windows etc.
-
If that’s the one’s promoted by Anna Ryder-Richardson I have heard they are not worth the money and don’t perform anywhere near as good as replacement roofing. As our doors and windows are 20 years old now the surveyor did say that there would be a need to support what is there but for the £5000 added to the bill the latest up to date totally Carlos Fandango windows and doors have glass which deflects heat in during winter and deflects excess heat in summer and the frames are already reinforced to accept the heavier roof weight. To me it seemed a no brainier to do the lor and be completely up to date, even if my pockets will be emptied.
-
No local double glazer did it who fitted the windows some years earlier. My tiles are a lightweight metal variety.

Went to the company we’ve been dealing with where her nibs saw a conservatory which had double glazed heat retentive glass double hipped roof. Guess what! Mrs CDMonte took one look muttered ‘Very Pretty’ and the budget has been shot,massacred,blown to bits. So no Chrissy pressies for me this year. Just a big hole in my pocket.
-
Do it once do it right - then she who must be obeyed will be happy. ;D ;D ;D
-
You’re right Ted doing it right is the way to please Mrs CDMonte.

Just to rub salt in the wounds, the engine in our car has blown up never rains but pours.☠️👹😱

Had our 10'x10' with 3 pitched sides done last year. £10k but has made a world or difference as it is now used as a normal room. I needed smelling salts when we first got the quote, but when I saw the amount of work involved, it made it a little easier. So glad we had it done now.

Won’t let on how much ours is going to cost, but smelling salts, defibrillator and a medical team on standby.

Touch wood I've not had an engine failure since 1970 - I thought my Jeep WK1 (2005) was a gonner last December when the EML fault turned out to be the swirl motors (Merc V6 Diesel) eventually decided against spending at least £2k to replace them (Jeep is worth less tha that).
Found a firm who did the software work around for £150 incl VAT - passed the emisions test a couple of months ago.
What vehicle is it?

Seat Toledo 1.9tdi 110 ps, we had her from new in 2003, when I took the engine cover off and peered through all the oil I saw broken ally in the undertray. With high powered light and mirror there’s a great big hole in the front of the sump. I think a big end has given up so it’s terminal as the old girl isn’t worth much money wise. We’ll be sad to see her go
-
Don't they use sintered conrod on those ?
Usually they're reliable motors though, commiserations as not good to see the insides on the outside.
As Ted though, can't remember losing an engine in ones I've looked after in family.
-
Used lumps are about but then you have to get it to talk to the ecu, if no rust about probably just about worth it

Owned it for 19 years sounds like it's done well - been a good buy - if you divide the cost price by 19 that sounds like cheap motoring per year even with adding maintenance costs !
Just inconvenient I guess.

It's usually associated with oil failure Ted. The sintered rods are very strong in compression load, don't rev that fast in a diesel and so dont' require huge levels of tensile (extending forces) performance at max revs, but are comparatively week for bending loads. Any failure in big end lubrication sees temperature rise in that bearing, the resulting seizure at that site tries to rotate the rod round with the crank pin and snaps it just above the crank end journal.
Pretty terminal quite quickly.
-
Agreed she’s been reliable in all the time we’ve had her, I can only think metal fatigue as she was regularly serviced by me,always checked levels before going anywhere and never had any journey mishaps. Pure bad luck😞
-
Obviously of little consequence now it's gone bang, but interesting topic nevertheless. I don't think that sintered construction suffers from fatigue, they manufacture them as a complete rod with fault line at the big end joints, then snap them to produce the two parts (it's this material characteristic that's desirable which gives low resistance to bending) that fit together with the grain structure making a perfect fit when bolted together and make a very accurate big end bore.
Hence the failure mode, any significant rise in bearing friction (threshold lays outside normal operating conditions) and the big end section is broken away from top of rod section. This either through failure of lubricant or supply. Depending on engine code, there were some iterations that had acknowledged oil pump drive failure that resulted in exactly this outcome. With a conventional steel rod it will usually just wear the bearing and you get that knocking that you know what it is but hope you've not heard "that" noise :)
A friend has just sold his 1.9 PD engined car with excess of 250,000 miles on it, serviced and new cam belt fitted, it was running really well.

I find it amazing that you not only know all these high tec engineering methods Nigel but you can remember them as well. I've never heard about sintered con rods that are actually snapped in two to make fit. Considering the high level of engineering and innovation VW use in designing engines the question has to be asked why do they use plastic (or fibre) timing gears that have a habit of stripping their teeth. I know of two people that have suffered with this failure leaving the engine as scrap. Back in the 70’s we were lucky to get 80-90k out of an engine but now the engines last forever and it's the failing electronics that scrap cars. Motorcycles are the same, electrical problems are the reason why modern bikes fail.
Interesting read though, thanks for posting 👍

I agree with Dave's comments - until yesterday I had never heard of sintered con rods.
When I was in the car trade in the 60's owners would boast about not breaking down during a journey from Derby to Cornwall.
As a salesman we would tell customers about Opel Rekord C owners who were still on original clutches at 90 k miles!
Times have changed for sure.

It's quite amusing that each mind stores all sorts of detail, with varying success in how we recall it and the motivation that drives the search. I joke with my kids that my warehouse of mind-crap is just much much larger than theirs and it may take a little time to find a competent answer which "must be here somewhere" ;D
I find accurate details of failure fascinating (not from a morbid point of view) but that it informs so much in how to look after that item and avoid potential failure if that's possible. Look at the aircraft industry for a run through of monitoring and knowledge of why things fail as example.
The VW stuff (a few friends share knowledge/labour etc on our own vehicles) and make it interesting to study them in more detail to look after them. The cam drive wheels, if that's the failure point Dave, are another component that's well made but you have to handle carefully to avoid compromise in their structure. You can never even tap them, only using specific puller to remove if necessary too, that's absolutely vital. Some of those aren't even keyed to camshaft and just driving on a long taper joint (cams locked, belt installed, tension applied while all drives can move freely to distribute overall tension, then tighten the cam to drive bolts to set everything in place) some of these routines people don't understand the reason why they are that way by design and fall foul of loadings running out of range for component. Some (vauxhall i believe had a period of them) have plastic based idlers on cambelt that failed because of not being replaced at correct interval.
Another problem is with cambelt driven water pumps, originally they were plastic impeller that would fail in the event of frozen coolant, being a sacrificial component (perfectly logical) they are often replaced with "real metal" one's, but if they do freeze the system the result is a shredded cam belt/missing teeth and catastrophic failure.
Engine life has improved hugely in cars though, principally I feel because of fuelling not being to excess (not diluting the lubricant is paramount)with very good control of this, along with "synthetic" oil. It's not because the oil is fundamentally better lubricant, but far more consistent flow characteristic can be achieved for optimum supply, but that's been enabled by the fuelling being better. A circular achievement but far reaching in terms of engine wear.

Used to be common to hear from the escort cvh owner " its only done 28000" when there 6 year old belt broke
-
I believe that fibre timing gears were originally introduced to cut down on noise. In many cases, metal gears were an aftermarket "mod" in the day to improve durability, however that did come at the expense of considerably more noise from the gears.
-
The old Ford Corsair 1600E had fibre can gears iirc.

And the Essex V 4/6 engines

Ooo! Had one of them Bryan, in this. Lovely grunt! 3.0s

^^^^^^^^^^
Beautiful, still got it? My first car was a 1600 gtxlr and my first brand new car was a 1600 laser. Always regretted not having a 3.0.
-
Had bikes then vans and my first car was a Jan 70 3.0 Capri GT XLR, had it for years till i bent it
-
The Me handicap in me wanted to find out what had failed in our Seat Toledo, eventually managed to get the sump off to find hole in the front and another three timed bigger in the rear. Once off I could see No 3 conrod was at an angle. Saw that it had snapped just below the piston skirt and had bent up between the crankshaft webs, really upset Mrs CDMonte as we’ve had Roxy from new in 2003. So it looks as though Auto Salvagers will be picking her up.

Me handicap should read Mechanic, poxy predictive text👹☠️

Wife has ME and yes its a shit but being a mechanic can be bad as well
