TU engines:  We have been informed that these are also a suitable replacement for the combined metal/rubber washers used on TU (954/1124/1360) engines fitted to most small Peugeots & Citroens from November 1987 onwards.  However, until this has been verified, we do not recommend that these washers are used on any TU engines.

Later Citroen/Peugeot engines: These washers are not suitable for models later than those shown above, (most of which use a smaller washer).

Copper sealing washers are designed to be used only once!!!:  When first used, the soft copper adjusts to seal against surface imperfections. The copper then becomes 'work-hardened' with forces that produce expansion, contraction, compression, etc.   If the hardened washer is then re-used, it may not seal.  The round-section crushable type should never be re-used. Although it is possible to to re-soften the flat solid type that we sell, by annealing, we recommend that a new washer is used each time, (as a major oil leak could be disastrous!).
