Nissan Skyline R32 engine factory workshop and repair manual download

- Safety first: work on a flat level surface, wear eye protection and gloves, disconnect the battery negative terminal, never rely on a hydraulic jack alone — always use good-quality jack stands rated for the car’s weight, and keep a fire extinguisher nearby.

Tools (what they are and exactly how to use them)
- Socket set (metric, 8–19 mm common): remove and tighten bolts. Use the correct socket size to avoid rounding heads; attach to a 3/8" or 1/2" ratchet for most bolts, and use a breaker bar for very tight bolts.
- Ratchet (3/8" and/or 1/2"): gives quick on/off access for bolts. Use extension bars to reach recessed bolts. Turn smoothly and avoid sudden jerks to prevent stripping.
- Torque wrench (click-style, 3/8" drive recommended, range ~10–100 Nm): critical for final tightening to manufacturer torque specs. Set the desired torque, snug bolts in a star pattern first to seat the gasket, then apply final torque until the wrench clicks.
- Combination wrenches (metric): for bolts in tight spots where a socket won’t fit. Use the box end for better grip and avoid the open end when possible.
- Breaker bar: for very tight or seized bolts; apply steady, controlled force.
- Jack (hydraulic trolley jack): to lift the car. Position on manufacturer lift points. Use only to lift; do not work under car supported solely by the jack.
- Jack stands (pair, rated appropriately): place under specified chassis lift points and lower car onto them; verify stability by pushing car lightly before going underneath.
- Engine support or secondary jack + wood block: when you need to slightly support or lift the engine if the subframe or engine mounts are loosened. Use a wide wooden block between jack and oil pan or engine cradle to distribute load.
- Oil drain pan (large capacity): to collect old oil; slide under drain plug and pan drop area. Empty and reuse or dispose properly.
- Funnel: for refilling oil cleanly.
- Gasket scraper / plastic razor blade: remove old gasket material without gouging mating surfaces. Use plastic first, metal scraper only if necessary and with caution.
- Wire brush and non-chlorinated brake cleaner or parts cleaner: clean mating surfaces of oil and debris. Spray, brush, wipe with lint-free rags.
- Lint-free rags or shop towels: wipe surfaces and hands.
- Rubber mallet: gently persuade a stuck oil pan loose without deforming it.
- Sealant (RTV silicone specified by Nissan or high-temp gasket maker): used only if the factory manual calls for it at corners or as a backup; follow manual directions for bead size and cure time.
- New crush washer for drain plug: replace every oil change when drain plug is removed; use a socket to tighten drain plug to spec.
- Gasket (oil pan gasket specific to engine): new OEM or quality aftermarket pan gasket. Some R32 engines use a formed rubber or cork gasket; check parts diagram for your engine.
- New oil filter and fresh engine oil (correct grade for your engine): always replace the filter when changing oil; use a funnel and check capacity in manual.
- Torque specifications and service manual (Haynes, factory FSM, or online manual): essential. Do not guess torque values or bolt tightening sequence.
- Pry bar (small): for delicate leverage if pan is stuck; use carefully to avoid bending pan.
- Flashlight or work light: for visibility under engine bay.
- Magnetic pickup tool: recover dropped bolts or washers from tight places.

Extra tools you may need (why they might be required)
- Impact wrench (air or electric): speeds removal of stubborn bolts but use cautiously; finish final torquing with a torque wrench.
- Engine lift or hoist: may be required if the oil pan cannot be removed with the engine in place on some configurations (depends on engine/transmission/crossmember arrangement). The hoist allows partial engine lift to create clearance.
- Subframe support tool or engine support bar: if the subframe/crossmember must be unbolted, the engine must be supported; this tool holds the engine safely without a jack under oil pan.
- Rotary tool or gasket-removal tool: for heavy, baked-on gasket material if scraper can’t clean it.
- Replacement oil pan: required if pan is cracked, warped, or severely corroded and won’t seal.

Parts likely required (why and recommended replacements)
- Oil pan gasket: required – the gasket is the primary seal and is why you’re performing the job.
- Oil drain plug crush washer: required – prevents leaks at the drain plug.
- Oil filter: strongly recommended – you’ll be draining oil so replace the filter while servicing.
- Engine oil (correct type and capacity for your R32 engine): required to refill; OEM manual gives capacity.
- Possible additional seals/gaskets: oil pump pickup O-ring or gasket, rear main seal (only if leaks are found during inspection), transmission-to-engine lower seal if disturbed. Replace only if damaged or leaking.
- Oil pan (replacement): only required if pan is damaged, cracked, or warped; inspect carefully when removed.

Step-by-step procedure (beginner-friendly, assuming basic tools and the ability to remove some undertray items)
- Prepare car: park on level ground, engage parking brake, chock rear wheels, disconnect negative battery terminal.
- Lift and secure: jack the car at the front jacking point, place jack stands under the correct subframe points, lower car onto stands and verify solid support. Keep a second support under the engine if you will be loosening mounts or the subframe.
- Drain oil: place drain pan under drain plug, remove plug with correct socket, let oil drain completely, replace drain plug with new crush washer and tighten to spec (or leave out until reinstallation if pan removal will interfere).
- Remove undertray and obstructions: remove plastic engine undertray/splash shields, heat shields, and any components (steering rack bolts, sway bar end links, exhaust downpipe, etc.) that block oil pan access. Keep bolts labeled/organized.
- Support engine if required: place a jack with a wood block under the oil pan cradle or use an engine support to take some load if you must remove crossmember or engine mount bolts.
- Remove subframe/crossmember if necessary: on many R32s you must lower or remove the V-shaped crossmember/subframe to gain clearance. Unbolt with correct sockets and support the subframe as you lower it. Keep alignment pins/bolts organized.
- Loosen oil pan bolts: progressively loosen all pan bolts in a crisscross pattern to relieve stress evenly. Use a breaker bar for seized bolts. Keep bolts in order by location — some are different lengths.
- Remove oil pan: once bolts are out, gently pry the pan free with a plastic scraper or small pry bar. Work around the perimeter; do not pry on thin sheet metal flanges. Lower pan slowly—there may be residual oil and the pickup tube may hold it.
- Inspect pickup and pan: check oil pickup tube and screen for debris, check for metal shavings (indicative of engine damage). Inspect pan for cracks, dents, or warping.
- Clean mating surfaces: scrape old gasket material from block and pan carefully until surfaces are smooth, then clean with brake parts cleaner or rag. Ensure no oil residue remains where gasket will seat.
- Fit new gasket: position the new gasket on the oil pan or block as required by part type. If the manual calls for sealant at corners or mating points, apply a thin uniform bead of specified RTV and let it “skin” per instructions before assembly.
- Reinstall oil pan: lift pan into position (with gasket) and hand-thread bolts to hold it. Tighten in a crisscross/star pattern progressively to the specified torque using the torque wrench.
- Reassemble removed parts: reinstall crossmember/subframe, steering rack, exhaust components, undertray, etc., torquing bolts to specs and rechecking engine mount clearances.
- Refill with oil and install new filter: install new oil filter per instructions (light coat of oil on gasket), refill engine with correct oil volume and type, reinstall oil dipstick and tighten filler cap.
- Check for leaks: start engine and let idle; inspect undercarriage for leaks around pan, drain plug, and filter. Re-torque pan bolts after initial run if manual requires (some manuals recommend recheck after warm-up).
- Dispose old oil and filter properly: take to recycling center or auto parts store that accepts used oil.

When is part replacement required (what to look for)
- Replace oil pan gasket: always replace the gasket when removing the pan or if leaking.
- Replace oil pan: if you see cracks, deep dents, severe corrosion, or if the flange is warped and won’t seal even after resurfacing. If pan is warped you can sometimes have it machined flat, but replacement is usually easier and safer.
- Replace pickup tube/screen or oil pump gasket: if bent, damaged, or leaking into the pan area, or if debris has damaged the screen.
- Replace drain plug or bolt: if threads are stripped or damaged.
- Replace bolts/studs: if any are rounded, stretched, or corroded; some manufacturers recommend replacing specific bolts (check manual).

Important cautions and tips (no-nonsense)
- Get the factory service manual or a reliable repair guide for your specific R32 engine (RB20/25/26 etc.) — torque values, bolt lengths, and removal steps vary. Do not guess torque numbers.
- Never work under a car supported only by a jack. Double-check stands and support points before going underneath.
- Keep bolts organized by location and length — mixing them up can cause threaded holes to bottom out or leak.
- If you find metal shavings in the pan, stop reassembly and investigate — that indicates internal wear or bearing failure and may require expensive engine work.
- If the job looks like it requires lifting the engine more than a small amount, get proper lifting/support equipment or have a shop do it.

Final checklist before finishing
- All pan bolts torqued to spec and in correct sequence.
- Drain plug and filter installed and torqued to spec.
- Correct amount and grade of oil filled.
- No leaks after warm-up and short test drive.
- Old oil/filter disposed of properly.
