там не гильзы! стенки цилиндра покрывают непомню уже как и каким сплавом.
М52, М60, М70 и остальные на их основе.
никасил заменили на алюсил в 93г, т.к. повышеное содержание серы
в бензине ослабляло покрытие, в результате быстро падала компрессия.
M52 с никасилом выпускались до 09.98 (т.е. до замены на M52TU). Алюсиловые моторы выпускались параллельно.

Only the M60 and the European M52 engines are affected.
The M60 was fitted to all the E34 530i and 540i V8 cars. It was not fitted to the earlier E28 5 Series or the later E39 5 Series. Also, the early E34 3.0 cars (pre-1991) were M30 powered 6-cylinder cars and were not affected.
The M52 was fitted to the European E36 3 Series, E34 and E39 5 Series. The early models had the M50 (no VANOS) engine, and the later ones had the M54 (double VANOS) engine. It is only the European single VANOS M52 units that were affected, and even then, not all of these engines were affected.
Check the casting number on your engine. As reported by Koala Motorsport, the M60 Nikasil engines are:
M60B30
1 725 970 or 1 741 212
M60B40
1 725 963 or 1 742 998
On the M60 block, the casting number is stamped on the engine, on the right side of the car directly alongside the 3rd cylinder, and slightly above the coolant drain bolt.
