Thanks for this unformation.
Has anyone used these valve seals and could they share their experiences?
Also for completeness, can you advise on the equivalent Turbo inlet valve seals and where is the best place to obtain them?
Are these inlet valve seals used for both inlet and exhaust seals for all 2.0 litre engines, as I have an early (1985) Efi?
Any recommendations on where to buy inlet & exhaust valves?
Thanks

Hi Jeff,
Thanks for the prompt reply which confirms my EPC which has the valve seals (inlet only for Turbo) as AHU 1626A and available from Rimmers.
I understand that the Turbo exhaust valve has a larger stem diameter (~8mm) which appears to require a larger cup valve and pair of cotter valves. Interestingly, the valve spring seats are unchanged from EFi. Can these normally be reused for head overhaul as they are unavailable from Rimmers?
My EPC advises that inlet valves are CAM 1235. Rimmers have UAM 7713 available (shown as fitted to SD1!) but would this fit my early Efi or Turbo cars?
I have looked through threads on this site and Wilcox of Wickwar is recommended but they now appear to be a Citroen dealer.
Can anyone recommend a supplier of head parts - valve springs, cup valves, cotters, valve spring seats?
Thanks

Wilcox have many parts for Maestro/Montego still in their warehouse. If you call them wait for the MG parts on the answerphone then speak to John Wilcox as he can help with any parts/part numbers1958 Ford Consul Convertible. I love this car

If you look at post 179, I have shown the different stem seal, turbo on the left, later model in the centre, efi on the right https://maestro.org.uk/forums/forum/...305#post336305Last edited by Jeff Turbo; 10th October 2022, 10:47.1958 Ford Consul Convertible. I love this car

I note from the post https://maestro.org.uk/forums/forum/...-configuration that engines after VIN 554319 have a combined valve seal and lower spring seat as part number UAM7497 for inlet valves. This would appear to include MG Maestro turbo engines.
Can this part be modified to fit the larger Turbo exhaust valve?
Alternatively as above Elring 104.380 has been suggested as a Turbo exhaust valve seal but how could this seal be attached to the lower seat?
Another question regarding earlier valve seals which had seperate lower spring seats. Were the valve seals attached to the lower seats or did they float between the spring seats?
