Ow yes, its an engine I know all to well.

They realy are a bag of nails.....the rockers wear so you cant set valve clearence properly (the tips are not hardened).

The bore wear on them is frightening

The chains get noisey and you cant change them with the engine fitted

The breather system is rubbish (but in this case clear because I have already checked).

Black death is fitted as standard.

They are gutless.



And, yes you can get them quiet but, you have to remove the rockers and re-profile them to remove the groove before setting the clearance.

Its shocking this crock was fitted well into the 00's in KA's.

Not impressed then?

[Marks DTM Calib]

Not in the least.....in the 60's it would have been a reasonable engine design but, by the 80's it should have been pensioned off.

I rememeber when I first met the X Mrs, she had a Fiesta 1.1 and the oil light was on, I filled it up with oil and she said 'oh it's been like that for a week!!!!'  
It was scrapped two weeks later! I asked the question... How many other red lights do you ignore then?  

Shocking!

Name some good pushrod designs then?

I can name one - going to see if you mention it.

[VXL V6]

The LS7 in the Chevy Corvette is a pushrod isn't it?

Good or bad I've no idea, but the Rover V8 was around for a very very long time in one guise or another. That was/is push rod via short hydraulic lifters on the cam.

Problem is, getting a car serviced is now relatively expensive compared to the value of a mundane car like this. I've spoken to people who say "it's not worth getting it serviced. It would cost more than is's worth" without realising that servicing is about replacing consumables. From an economic perspective, it doesn't make sense to fill some cars with petrol but you won't get far without it. In reality it doesn't matter how little your car is worth, if it's run out of brake pad you need to do something about it, just as you do when it's run out of petrol.

At the same time, main dealers have been peddling the myth that modern cars are so horrendously complicated that DIY car maintenance is now a thing of the past for most people, whereas when I was young I can remember my dad, and most of his mates, all did their own routine maintenance. I suspect taking it to a main dealer for new brake pads was even less affordable then than it is now, but people understood cars so they didn't, on the whole, get neglected.

I hope you warned them that the brakes now work well !. If they are used to pressing really hard cause of the previous state, and try that with 'MarkDTM brakes' they are going to get a shock !

The Rootes 1725 unit by any chance?

[Bo Bo]

I had a 957cc Fiesta Popular pushrob jobbie as my first car

Same as.
I could hardly ever get 1st gear, imagine trying to pull away in 2nd all the time

Not a bad unit but I prefer the 1.6 as that is quite a modern design - only real drawback is it is not a cross flow design and the port size is restricted, the yank V8s are pretty reliable though, actually there are a few decent push rod lumps around.

The A series is popular but not a good engine - eg long stroke, siamesed ports, 3 bearing, Xflow suffers from long push rods and is difficult to get to the followers, the Ford V6s all have problems the 2.5 / 3.0 head warping, the 2.8 siamesed ports, 2.9 don't know much about it.

Despite being a 3 bearing lump the old Land Rover engine is supposed to be quite good.

[Kevin Wood]

The Xflow isn't too bad, not because it wasn't rubbish to start with, but because of the number of people who have put effort into sorting out the issues and tuning them. Mate of mine had a 190BHP one They generally make the Exxon Valdez look oil tight and need regular rebuilds, especially if on the standard pistons...

It always amazes me how many pushrod engines are around in the US. Got a brand new Chrysler Voyager hire car a couple of years ago. Looked under the bonnet - pushrod V6 engine. I remember laughing about them as being antique when they were still fitting the Cologne to early 90's granadas.

I guess if anyone's going to put a V6 in a UK car it's got to be pretty refined and perform well. In the US it could well be going in a poverty-spec car and thus there's a market for basic engines that doesn't exist here.

I heard that Ford were developing a 2 stroke direct injection engine destined for the Ka but the EU emissions rules shifted and scuppered their plans so they had a rummage around in the parts bin and found the pushrod lump there.

[Martin_1962]

The ecotec V6s are a modern engine, nothing really clever but a good basic lump

I agree that some people people will have to spend a little more when i comes to maintaining their cars, and i would have fallen into that as well when i had my 84 reg 2.8i granny, but when you see the wrecks on the road that you and i both know at first sight would not pass a snail let alone an mot.There is no way anyone can say i didnt know when they put the brakes on and it sounds like a fileing cabinet being dragged along behind. Sorry but safty is first in my book.
