The secret was to fire it up from cold and not shut it down until it was good and hot.The M60 was a great engine and was used in the E34, E31, E32 and the 1994 E38 730i and 740i, but BMW was working on a replacement, the M62. By way of a comparison, the 735i produced 211hp at 5,700rpm, with a torque figure of 305Nm at 4,000rpm.The 4.0 though was the superstar, with an 89mm bore and 80mm stroke giving a 3,982cc capacity and 282hp at 5,800rpm. In 1997 the m60 was replaced with the M62. Fly-by-wire engine management (Bosch ME7.2) was used and, with the Vanos system, this resulted in a much healthier torque curve – the revised 3.5-litre unit was particularly good, and not far off an older 4.0.The M62TU was used in 4.6-litre form in both the X5 4.6iS as well as the Alpina B10 V8 E39. This was a nickel-silicon coating that was applied at the factory, then honed to produce a very hard, wear-resistant coating intended to generate less friction than a standard steel bore. The M60 engine produced 232 kW (311 bhp) in the B10 4.0. The V12 was a nice talking point but, at 295hp at 5,200rpm with 450Nm at 4,100rpm, it wasn’t a lot more powerful and it drank a lot more fuel (there’s a good 8-10mpg difference between the two).The M60 was an immediate hit, revitalising the E34 and E32, beating Mercedes and crucially, the Lexus LS400.

The M60 was installed in the E34.

The crankcase breather valve is built into the back of the inlet manifold and needs changing periodically. In its place came Alusil, which saw the entire block being cast from an alloy with a very high silicon content.
Among the additional changes were a reworked and improved intake system and new piston rings. Single valve springs replaced doubles as well, but that’s not a problem. So, it wasn’t as big an improvement over the 4.0 as the 3.5 was over the 3.0.In pursuit of better economy, the M62 was revised to be a lower-friction, hotter-running engine, and this is where the troubles started (especially once the years started rolling by). • Tapping noises from the rocker covers • Very scary rattling at start-up • A V8 that sounds like a diesel • Heavy knocking under acceleration The modern BMW V8 can make some horrible noises My first BMW V8 was a 1993 730i fitted with the M60B30. • The upper chains on the M62; you can see the tensioner plunger extending • Look closely and you can see the lighter section at the top of the bores; that’s the start of the Nikasil coating wearing away on this M60 engine.A new M62 mapped thermostat; you can see the electrical connector that takes power to the element to open and close it.This PCV (Positive Crankcase Ventilation) unit bolts on to the back of the M60’s inlet manifold, and is a bit of a cow to change.One cylinder bank on a 730i E32; you’ll need to remove the coils one by one to change the plugs, and to check for oil leaks.The basis of the M60 V8 engine was an alloy block with a 90-degree bore angle and, rather than using pressed-in steel liners, BMW opted for the Nikasil bore coating.The basis of the M60 V8 engine was an alloy block with a 90-degree bore angle and, rather than using pressed-in steel liners, BMW opted for the Nikasil bore coating.
This meant that the caps were guaranteed to be a perfect fit, and more accurate than the normal, machined type.A four-valve cylinder head was fitted to each bank, employing hydraulic tappets with double valve springs and chill-cast camshafts. The 4.4 has a bore of 92mm and a stroke of 82.7mm, producing 4,398cc capacity. Nikasil had been used by Porsche for a few years, and it was proven to work.A counter-weighted, five-bearing steel crankshaft (forged on the 4.0-litre, grey-cast iron on the 3.0) was used with stubby connecting rods of sintered metal, and fractured big end caps. The kit costs $6000.All rights reserved © 2014-2020 Drive-MY EN/UK. Power was rated at 232hp at 5,700rpm, and torque increased to 320Nm at 3,300rpm – a useful boost.The compression ratio was reduced to 10:1 and revised Bosch M5.2 engine management was fitted. The BMW M62 is a V8 DOHC piston engine which replaced the M60 and was produced from 1994-2005. Hey everyone, this will be a progress thread on my latest build. It's a 4 liter engine. If maintained correctly, though, this engine would simply run and run to 200,000 miles; if excessive cold starts were avoided, even the Nikasil units could do some monster mileages. A lazy 71hp per litre on a 10:1 compression ratio, and the 3.0 had the same specific output on a 10.5:1 compression ratio.As a comparison, the old 3.5-litre gave 60hp per litre, and the M30 3.0 six slightly more, at 66hp per litre. A successor to the BMW M60, the M62 features an aluminium engine block and a single row timing chain. The V8 was used to power the E53 X5 4.6iS, and was an engine developed by Alpina.

Rather than having a con rod where the big end cap was cut off, then both mating surfaces were machined and the result line-bored, the sintered rods had the big end caps fractured off by force.
Early non-Vanos M62s used the same intake manifold as the M60, but the Vanos-equipped engine used a more restrictive manifold design.
