S38B36 compared with other S38 versions

S38B36 or S38B38?

The S38B38 has 25 hp more than the S38B36 (340 against 315 hp), from 3.8 L instead of 3.6 L, and was built 1992–1996. A different capacity means a different crankshaft, pistons or head, and different software. It can be fitted as an upgrade with the matching engine control unit and wiring, but it is a conversion rather than a straight replacement.

S38B36 or S38B35?

The S38B35 has 55 hp less than the S38B36 (260 against 315 hp), from 3.5 L instead of 3.6 L, and was built 1988–1992. A different capacity means a different crankshaft, pistons or head, and different software. It can be fitted as an upgrade with the matching engine control unit and wiring, but it is a conversion rather than a straight replacement.

Common S38B36 problems

The S38B36 shares its weak points with the rest of the S38 family. These are the faults to check on a used unit and on your own engine. The full explanation of each is in the M88 and S38 guide.

Throttle bodies and sensors. ITB linkages, air flow meters and idle valves age and cause uneven running.

S38B36 maintenance

• 10W-60 synthetic is common, about 5.8 litres.
• Oil every 7,500 to 10,000 km; valve clearances every 20,000 km.
• Duplex timing chain with hydraulic tensioner.

S38B36 prices by model year

Engines from 1985–1989 have a median of 8.490,00 €, while units from 1990–1994 sit at 7.700,00 €. Newer engines usually cost more because they come from younger donor cars with lower mileage and later updates.

Buying a used S38B36: checklist

1. Sump, oil pickup and drive variants. Rear-drive, xDrive and front-drive cars can use different sumps, oil pickups and engine mounts even with the same engine code. Check that the sump matches your subframe and front axle.
2. Confirm the exact engine code. Read the code stamped on the block and compare it with the code for your car. Send us the last seven characters of the VIN and we confirm the match before anything is paid.
3. Look at the oil and coolant. Clean oil without metal particles and coolant without oil are good signs. Milky oil, oily coolant or a burnt smell mean the engine needs further checks before it is fitted.
4. Why your old engine failed. Before fitting a replacement, find out why the original failed. An overheating radiator, a blocked intercooler or a failed turbo can destroy a second engine if they are not fixed.
5. List of what is fitted. Engines are sold with different ancillaries: some have the turbo, injectors, manifolds, alternator and starter, others are long blocks. Agree the list in writing so you know which parts must come from your old engine.
6. Timing chain noise. Listen for a rattle at the front of the engine for the first seconds after a cold start. On an engine that cannot be run, look at the chain guides through the oil filler or with the valve cover off.
7. Bearing and valve clearance history. M engines are built to tighter tolerances. Ask for the last rod bearing replacement and valve clearance check, and consider an oil analysis if the engine can be run.
8. Originality and numbers. For collectible cars, the engine number and correct ancillaries add value. Photograph the stamp and keep it with the car's documents.

What is the difference between the S38B36 and other S38 engines?

The S38B36 makes 232 kW (315 HP) and 360 Nm. The other S38 engines are: S38B38 with 250 kW (340 HP) and 400 Nm (1991 to 1995).

Engines in one family share a basic block, but the turbo, the injection, the sensors and the engine computer can differ. A higher power version often has different pistons, a bigger turbo or a different fuel system.

This is why we ask for the exact code. Fitting a different version can work, but the wiring, the software and sometimes the gearbox must be changed to match.

What should I replace when I fit a used S38B36 engine?

A used engine lasts longest when it starts life in your car with fresh fluids and new seals. Fit a new oil filter and fresh oil of the grade BMW lists for this engine, and refill the coolant with the correct BMW antifreeze mix. Check the spark plugs and the ignition coils, and make sure the fuel lines are clean and tight before you crank the engine. Change the drive belt, the thermostat and the water pump seals if they look tired, because they are cheap while the engine is out.

Look at the engine mounts and the clutch or the torque converter while the engine is out. Old mounts can crack a new engine's brackets, and a worn clutch is much easier to change now.

Before the first start, turn the engine over without fuel until the oil pressure light goes out. Then let it idle, check for leaks, and drive gently for the first few hundred kilometres.

The warranty asks for fitting by a qualified mechanic and the correct oil, coolant and filters. Keep your receipts in case you ever need to make a claim.

How do I know a used S38B36 engine is in good shape?

Before a unit is listed, the yard checks the engine code against the listing, writes down the parts fitted to it, seals every opening and photographs the real engine you will receive. An inspection certificate for the unit can travel with the order when you ask for it.

When you look at a listing, check the recorded mileage, the year and the photos of the ports and the stamp. Ask for photos of anything you want to see closer. Ask the desk for more pictures of any listing. We are happy to show the stamp, the ports and the ancillaries before you decide.

On a petrol engine like the S38B36, a careful fitter will also look at the spark plugs, the coils and the timing side before the engine goes in.

If the engine fails inside under normal use, the warranty covers you. Eligible engines come with a 12 months warranty from the delivery date. It covers internal mechanical failure under normal use and correct fitting by a qualified mechanic or workshop.

Will the S38B36 engine fit my BMW E28 M5?

Yes, if your BMW E28 M5 was built with the S38B36. BMW used this 3.6 liter (3,535 cc) petrol engine with 232 kW (315 HP) in the E28 M5 from about 1988 to 1992.

Some E28 M5 cars were built with a different engine: the M30B34. These look alike from the outside, so check the code on your engine or send us your VIN.

Also tell us if your E28 has a manual or an automatic gearbox. The flywheel or the flex plate and some sensors depend on it.

Which cars use the BMW S38B36 engine?

BMW fitted the S38B36 to the BMW E34 M5 3.6 and BMW E28 M5. These cars were built with this engine from about 1988 to 1992.

The badge on the boot is not enough to be sure. The same model name can hide two different engines, for example after a facelift or a change in emission rules. Always read the engine code stamped on the block, or look it up with your VIN.

Other engines in the same S38 family are the S38B38 (340 HP). They look alike but differ in power, parts and electronics, so they are not always a direct swap.

How much power and torque does the BMW S38B36 have?

From the factory the BMW S38B36 makes 232 kW (315 HP) and 360 Nm of torque. It is a 3.6 liter (3,535 cc) inline 6, DOHC, 24 valve petrol engine with no turbo (naturally aspirated).

Without a turbo, the power builds smoothly with the revs. A clean air intake, healthy ignition and the correct fuel are key to getting the full figure.

A used engine reaches its factory numbers when it is fitted with the matching engine computer and software, and serviced with the right oil and filters. If the engine computer from your car is a different version, a specialist may need to code it.

Every S38B36 on our site lists its year and mileage. You can ask for extra photos, a close-up of the code stamp or a short video before you order.

Is the BMW S38B36 a diesel or petrol engine?

The S38B36 is a petrol engine. It is a 3.6 liter (3,535 cc) inline 6, DOHC, 24 valve unit with no turbo (naturally aspirated), and it was built to the Euro 1 emission standard.

The emission standard matters for registration and for low-emission zones in many cities. When you replace an engine with the same code, the car keeps the same paperwork and the same emission class.

Petrol versions need the correct catalytic converters and oxygen sensors on the car to stay legal and to keep the engine computer happy. Reuse the parts from your car if they are in good condition.

If you are not sure which version you need, send us your VIN. We tell you the right code for free.
