Thank you both. Huib, for the 1.2mm test with the head on the block - it would make sense that this is the thickness of the gasket if everything else so correct. If it is less I will need to get a thicker head gasket, as the rest of the engine is completely assembled now.

Hi everyone, I am in the home stretch with the engine rebuild. The engine builder phoned me today with a question though before he can finish the reassembly: The block (Series 1 1.3S) was bored to 77.8mm (0.8mm oversize) but the Spesso head gasket I have is very close to the bore size. Even though t...

I'm about to open my gearbox to replace the oil seals, but also because it drops out of 3d too easily when I depress the clutch. Great tips in this thread regarding the 3-4 slider that may be installed incorrectly. The other issue I want to check is 3d to 2nd down shift that crunches, even when not ...

When buying synchros they don't appear to list different parts for different gears:

Thank you so much for your reply Huib and Andreas.

While having the subframe separated from my car for engine work I am also carrying out various other jobs while access is easy. I have noticed my gearbox input shaft is leaking a bit into the belhousing and the side shafts are also leaking. I have bought a gearbox gasket kit including oil seals to t...

I managed to find an S2 manual. Valve/ guide tolerances are the same as S1. I wonder why the valve stem seals were fitted on S2 and not on S1?

[attachment=0]20231109_203528.jpg[/attachment] Sorry, the seals are at the engine builder so will check next time I am there. The attached valve guide to stem tolerances are from the S1 workshop manual (A and B). I would appreciate if someone with an S2 manual can perhaps check for me what these val...

Thanks Huib, I will install the seals with the new guides. There is a set in the engine gasket set I bought (black), but I might discard those and hunt for Viton seals as it is impossible to know what quality those in the gasket set would be...

Hi, I did a search on this topic but could not find anything on the forum. I am in the process of having my S1 Rallye 1.3S engine reconditioned. The engine reconditioner noted that I need new valve guides, but that my valves are good. My car currently does not have valve stem seals. I have order all...
