1972 E9 3.0 CSI - Chamonix

Iridium plugs are not recommended for m30 motors.

Having problems with sparks. Used Denso iridium for a few years now. Replaced them with new ones this season but spark is bad and the engine stalls - especially when sitting for a while.

Conventional wisdom agrees with HB Chris✓. Most recommend using standard copper core spark plugs as these were originally equipment from the factory.

That said, if you experienced no problems with Denso Iridium plugs, it is unlikely that switching to a different spark plug brand with a comparable heat range and design would make a noticeable difference in engine operation. Without additional information, perhaps your replacement spark plugs have an extremely wide gap that tests the limits of your presumably "stock" ignition system?

Service was done, changed oil to liqui molly classic.



MOT was done. Went together with my e24 and e46 m3.

Only did 830 km last season.

Season has started in Slovenia. Already took my e9 to first opening meet, here are some photos.

Quite some time now I felt that the suspension is a bit wobbly so I decided to replace all bushings and steering rods.

Did some shopping at W&N and also bought:

- front/rear discs with pads
- front/rear wheel bearings
- handbrake cables and handbrake pads
- steel coated brakes hoses
- radiator
- water pump, termostat
- visco clutch with new fan
- new clutch slave cylinder
- axle boot repair rubber
- driveshaft center mount and joint
- differential rubber mount....



I had an empty lift for a few days since my uncle who owns the shop went on vacation. Replaced majority of parts but still have to replace radiator, water pump, termostat, visco clutch with new fan and clutch slave cylinder and make wheel alignment,



Also noticed leak on the original front muffler. Since I already made a custom rear muffler, I decided to cut open the original one to see how internals are made and fabricate this one as well.



Got all the material and almost ready to put it together for test fit then weld it.

Only took a few days? You're a better man than me!

I hope you removed the metal band from the flex disc at the transmission.

Few days was like 5 days + 2 weekends and still not finished

I always use the 'few days' term to describe when I'll be finished.
Been doing it for 12 years now....

 

[RTHLSS1]

Forgot to add photos of finished exhaust



Last week I replaced parts that I had left from last year. Water pump, thermostat, radiator, and visco clutch with new fan.



Also did an oil service so it is ready for the new season.



I saw that the thermostat housing is a bit corded so I ordered a new one and will replace it next time when doing some maintenance.

I bought my 72 tii project when my son was 6. He's now 38 and it's still a shell.
