 Expert Posts: 4458    Location: Jelling, Denmark | took some days off this week as I had some unused vacation and what better way to spend those days than to work on cars  I started by finding the 998 cylinder-head that had the least cracks in the valve seats. never seen this problem with the 1275 heads, but obviously it is a problem with 998 heads as 4 of my four 998 heads had cracked valve seats. I then proceeded to find a set of valves to go in the head and lapped them in. lapping in valves is not the most exciting job in the world  when all valves were lapped in the valves was "pressure" tested using white-spirit. Besides lapping in valves I cleaned, sand blasted and painted most of the parts that was to be bolted on the the engine. I also disassembled, cleaned and renewed the distributor needed, mounted the cam chain and cover, oil filter housing and pipe and torqued down the head. the head looks very old, possibly off a morris 1000 but the chamber design is exactly like the head I removed from this care originally, so will be fine and not limit the all ready power limited car any more than the original engine anyway. pics:           | ||

Expert Posts: 4458 Location: Jelling, Denmark | removed the engine from this car last weekend, looks very worn and corroded there are some parts off the engine like the clutch cover and starter that I need to reuse. Also cleaned a few surface rust spots, applied rust remover and applied rust proofing paint. will paint the spots red later when the sun is shining outside       Edited by DotMatrix 17/4/2013 11:17 PM | ||

Expert Posts: 4458 Location: Jelling, Denmark | This weekend I finished assembling the engine, I made the mounting bracket that is missing as its a mini engine, and connected everything up and adjusted it all. Its now running and nice looking and I have covered the first 100 trouble free miles allready also painted the patches red that I painted brown with rust-proofing paint last weekend. Funny how the cylinderhead is from a 1966 mini 998, block is from a 70'ies mini and clutch, flywheel and starter is from the '89 metro and it just works together all of it         Edited by DotMatrix 21/4/2013 8:26 PM | ||

Expert Posts: 4458 Location: Jelling, Denmark | So fixed a few other small bugs on the car this week also. The speedo didn't work so fixed that, the cable wasn't fixed properly in the drive. cylinders 1 was very lean and then gradually got richer ending with number 4 which was to rich, I blame the metro having a sandwich thermostat plate where the heater gets it hot water instead of the place where the mini gets its water and after all this is a mini engine, so I don't think the engine was circulating water properly in the end of the engine opposite the water pump, so removed the sandwich thermostat plate and moved the hose to the normal mini place as you can see in the pictures, found a nice suiting hose from an other metro heater that had all the right bends allready. also worked on my needling abilities and sew the rubber mat on again as it was catching my feet anyway, pictures.     | ||

Expert Posts: 4458 Location: Jelling, Denmark | I adjusted the toe-out today as it was wearing the inside of the front tires. I found that it was toe'ing to much out and think this was the reason for this. While doing this I found a couple of holes in the floor at the usual spots and I fixed this.    | ||

Expert Posts: 4458 Location: Jelling, Denmark | did a few things on the 998 this weekend. Renovated the carburettor, cleaned it, new gaskets everywhere, new jet, new floating needle, and that is going to help a lot with the indeterminism of the adjustment screw previously as a shim was missing in side the carb, I must have lost it last time I took it apart to clean it other than that I put some under-sealant on in places where it was needed, took a rear wheelbearing apart as it was rumbling a lot and put new grease in, not that it fixed the problem, but certainly didn't hurt, fixed a crack in the exhaust downpipe and took the brakes apart because it wasn't breaking even.

Expert Posts: 4458 Location: Jelling, Denmark | A bit of work on the 998 this weekend. The cooling system wasn't holding water, it was slowly seeping out in each end of the cooler, you can see on the pictures where I have tried to make it hold water by making the plastic ends fit tighter. other than that the cooling cap was bad and the system wasn't pressurising, I found an other cooling cap on the old spare parts mgf I have out the back and that fit perfectly. The radiator in this car was of the thin type and was the only one of that type I had, so I made a reconditioned mk 1 brass radiator fit under the mk2 front, not pretty and hold on in one end by a zip tie but works really well other than that the drivers seat wouldn't fold forward because one of the cables had snapped, so I fixed that using a cable from another seat.     | ||

Expert Posts: 4458 Location: Jelling, Denmark | changed two winter tyres that were worn down and put winter wheels on the car today, also let all the hydragas out and checked the radius arms for play as I thought one of them might be worn out, but it turns out none of the two rear radius arms wasn't luckily. also changed the grease in one of the rear wheel bearings as it had become dark brown and wasn't greasing properly. at the same time I put antifreeze in the cooling so it should be ready for the winter now.

Expert Posts: 4458 Location: Jelling, Denmark | the car has to go in for its MOT today, so I have been doing some small things on it in the last week. changed the spark plugs, fixed a crack in the exhaust, changed the ignition-lock electrics, cleaned some of the oil off the back of the engine and changed the steering column plastics as it was fouling the hazard warning switch. lets hope the MOT goes well    | ||

Expert Posts: 4458 Location: Jelling, Denmark | the car wasn't braking evenly on the two rear wheels, so I took the rear brakes apart and discovered that the side not braking well enough of the two rear wheel cylinders was leaking so I found a used spare I had and fitted and bleed that and changed the brake shoes also. the right hand side lower ball join had too much play in it so changed that with a new one I had among my spares. also bought a new radiator off ebay which arrived today. very nice reconditioned radiator I will be fitting this shortly in order to get a radiator that is the right type, fits properly and isn't leaking but now it has its new MOT for the next two years and besides the radiator which isn't changed yet it is booked for a rolling road adjustment session on the 13'th of february with the same guy that adjusted my blue racer, so hopefully this will make it perfect       Edited by DotMatrix 31/1/2014 2:31 PM | ||

Expert Posts: 4458 Location: Jelling, Denmark | today I fitted new front rebound-rubbers. I have also bought new rear rebound-rubbers but cannot get the bolts out so need to heat them up in order to free the bolts. anyway. a few pics of the front bumpstops.       | ||

Expert Posts: 4458 Location: Jelling, Denmark | today I had the car adjusted on a rolling road as it was running a bit badly, shooting back a bit when under load and didn't quite wanna "go" (as much as a standard 8.3:1 compression 998 wants to go anyway ) It was adjusted and is now running a lot better. numbers on the attached rolling road printout are the final and best run. It can be hard to see the graphs as we did a few runs, but it started at 41.7hp and ended at 45hp which isn't much of a change, but with a much nicer torque curve and up from 68nm to 73.6nm so I'm happy. although it does make me want to fit a sporty exhaust and raise the compression as something like 55hp would suit it much better  Edited by DotMatrix 13/2/2014 4:48 PM | ||

Expert Posts: 4458 Location: Jelling, Denmark | R100_vvc - 13/2/2014 11:27 PM Nice work, isn't 45hp spot on to the factory power it should be? its pretty close yes, it should be 48hp as this used to be a high compression 998, but the current engine is a low compression 998 from a 70'ies mini so it should have 41hp but as it is fitted with a kent 256 cam and the better metro manifold i guess that adds up to 45hp | ||

Expert Posts: 4458 Location: Jelling, Denmark | R100_vvc - 14/2/2014 12:12 AM cool, I don't know much about the A series. I have just bought my self a Austin metro 1.3 L not sure what power it will have, but seems pretty nippy Nice the A-series is a nice engine and they are pretty nippy yes, but you can easily feel the difference between the lighter engined mk3 with better front suspension and the older setup of the A-series when driving. I believe the standard 1.3 Austin has 62-63hp on paper. have you posted pictures of it yet? | ||

Expert Posts: 4458 Location: Jelling, Denmark | decided today to paint a few rust spots on the rear and on the front of the car now that the winter seems to be over. removed the rust with a drill fitted with a spinning wire brush, painted the bare metal with rust resistant primer and then finished it with rattle cans. not the prettiest of jobs I know, but prettier than it was    | ||

Expert Posts: 4458 Location: Jelling, Denmark | I know it's a bit cheap looking, but bought a cheap tailpipe and fitted which looks much better than the rusty bendy original one. now it only needs a set of alloys  | ||

Expert Posts: 4458 Location: Jelling, Denmark | the right hand side wheel cylinder has been leaking for some time now and I fixed this today. I had initially bought two 1275gt clubman wheelcylinders as they are the right size for a metro and fit and I could not get the metro ones. unfurtunately these had inch thread where as the ones on the car had millimetre thread and I didn't have any inch threaded brake unions, so I ended up abandoning fitting new wheel cylinders for now and instead removed one of the cylinders from the back of the blue MG I bought some time ago. this wheel cylinder had the right thread and looked quite new, so I fitted this and bleed the system and all is now ok.

Expert Posts: 4458 Location: Jelling, Denmark | not much news really. the car is driving every day and its driving great. right now I am having a set of alloys sandblasted and painted which I bought a while ago from metromartin and you will never guess the color I found a right hand side rear fog lamp which I plan to install and also changed the windscreen wipers   | ||

Expert Posts: 4458 Location: Jelling, Denmark | changed the radiator yesterday. the thermostat in the old one was not working so when driving in queue's the car got very hot, and was frequently over half way on the gauge under normal driving. Besides this it didn't heat properly in the cabin in the winter. To fix this problem I also plugged the bypass hose between the waterpump and cylinderhead as it was a mini engine, the theory is that this bypass hose was leading to much hot water around the heater making the car not heat the cabin properly. the reason for changing the radiator was that the old radiator was a mk1 radiator that was made to fit and the new fits properly in a mk2.
