John, John, John, John, John, John, John, you just can't keep it in your trousers can you?! (Your wallet, I mean, obviously!) Still, another one saved, so well done.

How's KX54 coming along?

Thumbs up

Only just seen these... Hence tardy response ...whatever happened to notifications? About to update thread on a little progress and spotted these latest posts.

Haha ... so true. I can resist anything but temptation..

These nicer MG ZT "project" cars have bottomed out in value now and such opportunities will not be around in a few years maybe sooner. I currently have a couple of ZTs in daily use... @ 270 pa VED ( probably go up in a few weeks ) KX54 is on the back burner until I clear the decks. Just a few simple jobs to do on it but, 270 takes some finding so it's on SORN.

Will sort it when the warmer weather and lighter evenings are here. The garden daffodils are popping up and will flower soon. Love the early spring. Cheltenham Races... start of Flat Racing and Formula 1 seasons and nicer conditions to play with the cars.

The jubilee clips are prone to collapse the unsupported plastic t-piece, because they do not grip evenly and the plastic stub soon ends up egged with heat or even worse collapses with too much pressure applied. You would be better going back to the scrappy and also collecting some of that spring type of clips which give an even clamping force. There are a few spring clips fitted to a KV6 that will fit.


This is the reason folks end up cursing the original plastic t-piece and buy an alloy t-piece instead because during the life of the car the original swaged pips clips loose their tension and start to leak, the clips also cut into the easily cut turbo hoses leading to leaks. some folks cut a little bit off and fit them with a jubilee clip only to find them leaking again. If decent spring clips and a light touch are used you will not have an issue with the plastic t-piece.

Having spent the whole weekend on sons ZS180 doing the timing belts and finding all sorts of leaks. I found the dreaded jubilee clip bodger had been at it on plastic housings too and had collapsed the pipe.

Jubliee clips work well on older cars which are mainly fitted with metal stubs but if you use them on plastic you are asking for a problem if you cant control the tightness of the jubilee clip.

Some plastic stubs have metal inserts where the jubilee clip will work fine such as the intercooler hose on the turbo models. MG Rover in their wisdom unfortunately decided to omit inner metal sleeves from the plastic connection for one reason or another to the detriment of the vehicles life if some heavy handed person sets to the car.
Haha.. you're norf of da buddr ... so that's like foreigner territory to us Southerners... More seriously, if you're ever in these parts and have time to pop by for a chat and a cuppa, please get in touch. Over the years I have met many MG and Rover enthusiasts and always enjoy sharing experiences about a common interest. I take pictures of the cars of every visitor. Now well over one hundred. My older son also has many young MG and Rover enthusiast friends and he often had visitors, including one from as far away as New Zealand who keeps and MG Midget here for visits. :~



Note Kiwi on the Door....

================

Now to your post.

Thanks for that comprehensive reply about the hoses and clips etc..

With what you explain already in mind, I have already collected a small tub of those constant pressure hose clips from scrapyard visits. I have also bought the correct tool to compress and fit/remove them. Prior to getting that tool, I did not like the things. Now I do... old dog, new tricks myth buster... ... and have ordered THREE Alloy 1.8t Coolant T-Pieces. Have already fitted one. So those plastic jobbies will soon be a thing of the past.

I worked on this car briefly today as the weather had improved and so did the light. Watch the next thread update on this project car I will prepare soon with illustrations. Work was slowed and delayed as I came across three heavy handed bodges. In previous ownership large Invoices were for the professional work on this car. I half anticipated this in view of how silly tight that 22mm Crankshaft Pulley Bolt was. So unnecessary ...All very sad.

Apparently ... in a parallel universe MGJohn drives .........A.......

B>>M>>W ....

Arrrrrggghhhhh......... ......

Thumbs down There's more ... progress update.

Not touched this car for a couple of weeks.

Bit disappointed with the little work today. Here's why.

Made a start on Cylinder Head removal which soon revealed some heavy handed treatment. Two of the 8mm Bolts which fasten the Ignition Coli Packs had been overtightened. Cue soft alloy threads destroyed. .. :~



and the other one too :~



Next work to remove the four Spark Plugs and with the stripped threads above in mind, I was anticipating more of the same. Plugs 1,2 and 3 came out smoothly as you would expect but Spark Plug in Cylinder No. 4 was silly tight. I had to use this Breaker Bar vigorously and carefully until it came out. :~



Here's that Spark Plug :~



There's another bodge. The HT lead held against the alloy Camshaft Cover and the Electrical Loom which should be there loosely nearby. :~



So that's three stripped threads which will need attention... Helicoil if not too far gone. Will know more when head is removed. I hope I find no more heavy handed treatment. That massive Invoice for the pro-work done on this car still fresh in my mind.

However, not all bad news to report, all that possible Head Repair Work or scrap it decisions can wait. Meantime I have two K-Series Cylinder Heads refurbished on standby all ready to fit... Be prepared as the old saying goes.

Hi John
been reading a lot of your stuff tonight, really good and interesting stuff
and I wonder if you can help me with my problem, I've been doing a CHG on my Rover 25 and now trying to install new valves, got the old ones out easily by the hammer way, I have now bought my second spring compressor to install them but none of them worked, could you recommend one that will suit the job, been of road from before Christmas as poor weather not allowing me much time to work on it, and getting some agro indoors,
HELP!

'er indoors? ...

Yes, accessing the valve springs with a compressor is sometimes difficult on the little K-series. I have two Compressors, one works fine on the restricted reach access of the K-Series but the other does not. I will take a picture of it sometime soon so you can see which one works and search your local Machine Mart or w.h.y. to find one to suit. It has two reversible ends which fits various valve cap sizes.

Here's a tip for you are anyone working on these cars.

By the way, if you have a local "remove it yourself" car breaker yard ( like wot I do ... ... ); good used Rover/MG K-Series Cylinder heads can be picked up relatively cheaply. Get one and prepare it ready to fit. Because traders no longer see these cars as "nice little earners", mainly due to trading constraints, perfectly good cars taken in part exchange are driven straight round to the breakers now. In my favourite local breakers, I removed a cylinder head from a Rover 75 1.8 turbo which according to the VOSA MoT records, had only done 39,000 miles. I also got the Turbocharger and other useful bits. They will come in handy one day ... they always do for me or someone needing parts for their cars.

Then sort out the original Head and keep as a good spare or sell it.

Helps to keep the cost of motoring down.

Removing K-series Cylinder heads for spare to have in need is something I can advise as well as I am doing it too. I have spare cylinder head for my 8 valve k-series engine.

Cool Best sunshine of the year today.

Took advantage of the superb sunshine and mostly clear blue skies for three hours working on the car. Progress is slow removing the Cylinder Head due to numerous reasons, mostly beyond my control.

First I drained the coolant by releasing two of the lower Constant Pressure Clips either side of the PRT ( Pressure Relief Thermostat ) and carefully pulled the big hoses away from the PRT. Lots of dirty coolant rushed out. I used a large plant pot drip tray to collect the coolant. Then poured it carefully into a plastic container. I will not reuse it and here's why. That's not Gold Dust but traces of "snake oil" coolant additive. It most certainly would not stop the unseen small split under the short hose connected to the T-Piece.



I half suspected to see something like that as there were traces in the Coolant Expansion Bottle. I will use SPEEDFlush when repaired car is up and running. That will effectively clear any unwanted stuff from the whole cooling system including the Heater Matrix.

Next job I always not like to do. Undoing the four nut/studs which secure the Exhaust Manifold to the Exhaust Downpipe/Turbocharger. There are three upward facing studs with 13mm Nuts, these were Hex Nuts ( six sided ) but earlier cars often had Bi-Hex ( twelve points ). The fourth stud nut faces downwards and is always difficult to access and undo. This one above the Wastegate Opening Crank.



In the past, to provide better access, I have disconnected that Wastegate Actuator Rod by releasing that pesky C-Clip ... which usually springs away at Mach 1 into the Unknown. Been there done that and will not need to do that today on the Hex-Nut. Will deploy ... Enter the 13mm Crow's Foot Socket ...



It worked perfectly ... Hoo-bleedin-Ray ...



The upward facing Stud Nuts were much easier to deal with once sprayed liberally with Penetrating Fluid., Again the Crow's Foot Socket helped access that one Nut shrouded by the Manifold itself.



That done, turned my attention to the top of the engine. Undone the 13mm bolt and its 15mm Nut which holds the Alternator, and now free, pushed it towards the radiator to allow access for Cylinder Head removal later. Then undid and stored all fifteen 8mm Bolts which hold the Camshaft Cover and its Gasket in place. Those lifted off easily revealing a coolant-mix free Camshaft assembly Area. Good to see that. So if there is escaping compression gasses over pressuring the Cooling System, oil does not appear going that way at all. There may not be anything wrong with the CHG. I will fit a new one anyway along with a pre-prepared Cylinder Head assembly. Here's what was revealed with cover removed :~





That allowed access to the Ten Through Bolts and all ten were undone a few turns once I had rotated both Camshafts to allow access to the two through bolts between Cylinders three an four which are usually blocked by Camshaft Sensor Half Moon Lobes which are always in the way.

Half way through this work, a near neighbour who usually finishes work early on a Friday, fired up his 6.2 Litre V8 Mercedes-Benz weekend car. Lovely noise.

Want to come for a ride John? Damn... I had to decline his kind offer as it would take best part of twenty minutes to collect up all the kit and tools and lock them away. I was promised another time.

Then used my Blue ZT-T to visit a relative nearby as my back reminded me I am no longer in my mid-thirties and it had had enough... Tomorrow's another day..
