The headliner board is very fragile - don't bend or it will break.
Lseat.com offers excellent pattern-matched E36 seat covers.
The M3 and standard E36 have different seat mounts and covers.
Use 3M Super 90 for headliner - it's stronger than 77.
Work in moderate temperatures for best adhesive performance.
Take photos during disassembly to help with reassembly.

⚠️ Warnings

E36 airbag-equipped steering wheels require SRS precautions - disconnect battery and wait 10 minutes.
Power seat harnesses can short - always disconnect battery first.

DIY Maintenance Guides

Step-by-step tutorials for common maintenance tasks

Oil Change

Easy 30 min $40-60

Complete oil and filter change procedure for M50 and M52 engines.

Interval Every 5,000-7,500 miles

Cost (DIY) $40-60

Tools Needed

17mm socket or wrench
Oil filter wrench or 36mm socket
Drain pan
Funnel
Jack and jack stands
Torque wrench

Procedure

Warm up the engine for 2-3 minutes to thin the oil for better drainage.
Safely raise the front of the car and support on jack stands.
Locate the oil drain plug on the passenger side of the oil pan.
Position drain pan and remove the 17mm drain plug. Allow oil to drain completely (5-10 minutes).
Replace the copper crush washer on the drain plug.
Reinstall drain plug and torque to 18 ft-lbs (25 Nm).
The oil filter housing is on top of the engine - remove the cap with a 36mm socket or filter wrench.
Remove the old filter element and O-ring from the cap.
Install new filter element and lubricate the new O-ring with fresh oil.
Reinstall filter cap and torque to 25 ft-lbs (34 Nm).
Remove the oil fill cap and add 6.9 quarts (M50) or 6.5 quarts (M52) of 5W-40 or 0W-40 oil.
Check level with dipstick - add oil until it reaches the upper mark.
Start engine and check for leaks around drain plug and filter housing.
Recheck oil level after engine has run for a minute and settled.

Pro Tips

BMW E36s use a cartridge-style oil filter - never install the metal canister type.
Always replace the O-ring on the filter housing cap to prevent leaks.
The oil filter housing gasket is a common leak point - inspect while changing oil.

Valve Cover Gasket

Easy 1 hour $30-50

Stop oil leaks with a new valve cover gasket - one of the easiest E36 repairs.

Interval As needed (typically 80,000-120,000 miles)

Cost (DIY) $30-50

Tools Needed

10mm socket
Flathead screwdriver
Gasket scraper or plastic razor
Clean rags
RTV sealant (optional)

Procedure

Disconnect the negative battery terminal for safety.
Remove the cabin microfilter housing cover (4 clips) for better access.
Disconnect any electrical connectors on top of the valve cover (coil packs, etc).
Remove the oil fill cap.
Remove the 10mm valve cover bolts (15 bolts total) in a spiral pattern from outside to center.
Carefully lift the valve cover straight up - it may stick from the old gasket.
Clean all old gasket material from the valve cover and cylinder head mating surfaces.
Clean the spark plug tube seal areas thoroughly.
Install the new gasket onto the valve cover - it should snap into the groove.
Install new spark plug tube seals (often included with gasket kit).
Apply a small dab of RTV at the corners where the timing cover meets the head (optional but recommended).
Place valve cover back on the head, ensuring gasket is properly seated.
Install bolts finger-tight, then torque to 89 in-lbs (10 Nm) in a spiral pattern from center outward.
Reinstall oil cap, microfilter housing, and reconnect electrical connectors.
Reconnect battery and start engine to check for leaks.

Pro Tips

Do not overtighten valve cover bolts - the plastic cover can crack.
Replace the spark plug tube seals at the same time to prevent oil pooling around plugs.
Check the grommets on the valve cover bolts - replace if cracked or deteriorated.

7mm Allen socket for caliper pins
Flathead screwdriver
Brake caliper piston tool or C-clamp
Wire brush
Brake cleaner
Brake grease
Jack and jack stands

Procedure

Loosen lug bolts while car is on the ground, then raise and secure on jack stands.
Remove wheel to access brake caliper.
Disconnect brake pad wear sensor if equipped (front driver side, rear passenger side).
Remove the two 7mm Allen caliper guide pin bolts from the rear of the caliper.
Swing the caliper up and support it - do not let it hang by the brake hose.
Remove old brake pads from the caliper bracket.
Inspect rotor for scoring, cracks, or minimum thickness. Replace if worn.
Clean caliper bracket pad contact points with wire brush.
Use piston tool or C-clamp to compress the caliper piston back into the housing.
Apply brake grease to the pad backing plates where they contact the caliper bracket.
Install new pads into the bracket - the pad with the wear sensor slot goes on the inner side.
Swing caliper back down over the new pads and reinstall guide pin bolts. Torque to 22 ft-lbs (30 Nm).
Reinstall brake pad wear sensor.
Reinstall wheel and torque lug bolts to 88 ft-lbs (120 Nm) in a star pattern.
Repeat for all four corners.
Before driving, pump the brake pedal several times until firm to seat the pads.

Pro Tips

Open the brake fluid reservoir cap when compressing pistons to prevent pressure buildup.
Clean rotors with brake cleaner to remove any oils before installing new pads.
Bed in new pads with 5-10 moderate stops from 30 mph to transfer pad material to rotors.

Cooling System Refresh

Intermediate 4-6 hours $250-400

Replace expansion tank, thermostat, and water pump to prevent overheating failures.
