Valve cover gasket on Nissan Qashqai - a small but critical part, the condition of which determines the tightness of the engine lubrication system. Over time, rubber products lose elasticity, dry out or become deformed, which leads to oil leaks, contamination of the engine compartment and even the risk of dirt getting into the oil channels. Owners Kashkaev first (J10, 2007–2013) and second (J11, 2014–2021) generations most often encounter this problem at mileages of 80,000 km or more, but in the Russian climate, replacement may be required earlier.
In this article we will look at all stages of valve cover gasket replacement on Nissan Qashqai with gasoline engines HR16DE (1.6 l) and MR20DE (2.0 l), including fault diagnosis, selection of original and analog spare parts, as well as assembly nuances that even experienced craftsmen miss. We will pay special attention a typical installation mistake is overtightening the cover bolts, which leads to deformation of the aluminum surface and repeated leaks. If you notice oil marks on the cylinder block or the smell of burnt oil from under the hood, these instructions will help you save money at the service station and get the job done right the first time.
Signs of Valve Cover Gasket Wear: When to Replace
Valve cover gasket on Qashqai rarely fails suddenly - usually the problem develops gradually. The first symptoms are often ignored, chalked up to “trifles,” but delay can result in oil getting on the timing belt or in the crankcase ventilation system. Pay attention to the following signals:
- 🔴 Oil stains on the cylinder block or head near the valve cover. On HR16DE leaks often appear in the area of spark plug wells, on MR20DE - closer to the back of the cover.
- 🔥 Burnt oil smell when the engine is running, especially after warming up. This means that oil is reaching the exhaust manifold.
- 🛢️ Oil level between replacements it drops faster than usual, but there are no visible leaks under the car - some of the oil escapes through the gasket.
- 🔍 Throttle valve contamination and the intake tract with oil dust (through the crankcase ventilation system).
On Nissan Qashqai J11 with engine MR20DD (2.0 l, 144 hp) may additionally manifest itself unstable idle due to oil getting into the throttle assembly. You can check the condition of the gasket visually by removing the decorative engine cover (on J10 it's plastic, J11 - with sound insulation). If traces of oil are visible at the junction of the cover and the block head, replacement is inevitable.
⚠️ Attention: On engines HR16DE After 2012, the valve cover gasket often becomes dull due to poor quality material. If you notice that the new gasket has become hard after 20–30 thousand km, ask the dealer for a replacement under warranty (if you have a receipt).
Which gasket to choose: original vs analogues
Original valve cover gasket for Nissan Qashqai supplied under article number 11040-ED00A (for HR16DE) and 11040-4M00A (for MR20DE/MR20DD). The cost from official dealers is from 1,800 to 2,500 rubles. However, many owners prefer analogues, which often surpass the original in durability. The table below shows the tested options:
| Manufacturer | Article | Engine | Price, ₽ | Features |
|---|---|---|---|---|
| Nissan (original) | 11040-ED00A |
HR16DE |
2 200–2 500 | Soft rubber, but can harden at low temperatures |
| Elring | 725.170 |
HR16DE/MR20DE |
1 200–1 500 | Improved composition, resistant to oil and temperature |
| Victor Reinz | 71-36986-00 |
MR20DD |
1 600–1 900 | Reinforced gasket, recommended for turbocharged versions |
| Corteco | 230383001786 |
HR16DE |
900–1 100 | Budget option, but may require replacement after 50 thousand km |
When choosing an analogue, pay attention to gasket material: the best option is reinforced rubber (for example, at Victor Reinz). Avoid cheap porous rubber pads - they quickly lose their shape. Also check the contents: in some sets (for example, Elring) additionally go spark plug well sealing rings, which should also be replaced at the same time.

Tools and preparation: what you need for work
Replacing the valve cover gasket with Nissan Qashqai does not require specialized equipment, but without the right tools the risk of damaging the cover or head increases. Here is a complete list of everything you need:
- 🔧 Head set with a ratchet (it is necessary to have a head on
10 mmfor cover bolts). - 🔩 Torque wrench (critical for proper bolt tightening!).
- 🧴 Carburetor Cleaner or WD-40 to remove old sealant.
- 🧼 Lint-free cloth And solvent (For example, White spirit) for cleaning surfaces.
- 🔨 Plastic spatula (to remove the old gasket without scratches).
- 🛠️ New sealant (For example, Loctite 574 or ABRO 99-003 - only for joints, if required).
Before starting work necessarily follow these steps:
Disconnect the negative terminal of the battery|Remove the decorative engine cover|Clean the surface of the valve cover from dirt (use compressed air)|Check the oil level - if it is above the maximum, drain the excess-->
On Qashqai J11 with engine MR20DD additionally need to be removed intake manifold, as it blocks access to the rear cover bolts. To do this you will need a head 12 mm and a screwdriver for loosening the pipe clamps. Don't forget take a photo of the location of the vacuum hoses before removal - they are easy to confuse during reassembly.
If the valve cover bolts are stuck, do not try to rip them off - treat them WD-40 and let stand for 10-15 minutes. Using force may break the bolt or deform the cover.
Step-by-step instructions for replacing the gasket
The process of replacing the gasket Nissan Qashqai takes from 2 to 4 hours depending on experience and difficulty of access. Below is a universal instruction for engines HR16DE And MR20DE/MR20DD, taking into account their design features.
Step 1: Removing the Valve Cover
1. Remove decorative engine cover (on J10 — 4 plastic clips, on J11 - 2 bolts per 10 mm).
2. Disconnect crankcase ventilation pipe (it is attached with a clamp to the lid). On MR20DD additionally remove throttle assembly And intake manifold.
3. Carefully unscrew all cover bolts (there are 15 of them per HR16DE and 17 on MR20DE) in the reverse order of tightening (from the edges to the center). Use the head on 10 mm.
4.Pry up the cover plastic spatula (not metal!) and remove it. If the lid is stuck, tap it with a rubber mallet.
Step 2: Removing old gasket and cleaning surfaces
1. Remove the old gasket from the cover and head of the unit. If she glued with sealant, use carburetor cleaner and a plastic scraper.
2. Clean thoroughly seating surfaces on the cover and head of the block from oil and sealant residues. This will lead to leaks of the new gasket!).
3. Check cover plane — if it is deformed (for example, from overtightening the bolts), the cover will need to be grinded or replaced.
How to check the flatness of the cover without a special tool?
Place the lid on a flat glass surface (for example, table glass) and try to illuminate the crack with a lamp. If the gap is more than 0.1 mm, the cover is deformed and needs to be repaired.
Step 3: New Gasket Installation and Assembly
1. Place a new gasket on the cover, making sure that all holes match with bolts and oil channels. Do not use sealant if the gasket rubber with reinforcement (For example, Victor Reinz).
2. Carefully install the cover on the block head, avoiding displacement. Start at the front and gradually lower the back.
3. Tighten the bolts to 3 stages according to the “criss-cross” pattern:
- First stage: moment 3–5 Nm (just “by hand” with light effort).
- Second stage: moment 7–9 Nm (use a torque wrench!).
- Third stage: final tightening to 10 Nm.
4. Connect all connections and hoses in reverse order. On MR20DD don't forget about intake manifold o-rings (article 14035-4M00A).
Overtightening the valve cover bolts is the main cause of repeated leaks! The maximum tightening torque is 10 Nm. An excess of even 1–2 Nm will deform the aluminum cover.
Common mistakes and how to avoid them
Even experienced craftsmen make mistakes when replacing the valve cover gasket with Nissan Qashqaiwhich lead to repeated leaks or damage to parts. Here are the most common mistakes and ways to prevent them:
- 🔧 Using old sealant. If there are traces of sealant left on the lid, they must be completely removed. The new gasket should rest against a clean surface.
- 🔩 Incorrect bolt tightening sequence. The bolts need to be tightened from the center to the edges in a crisscross pattern, not in a row. Violation of the order leads to deformation of the lid.
- 🛢️ Ignoring O-rings. On
HR16DEpeople often forget to replace the spark plug rings (part number11195-ED00A), which leads to oil leakage into the spark plug channels. - 🔥 Engine overheating after assembly. After replacing the gasket, let the engine idle for 5-10 minutes to allow the gasket to settle. Don't accelerate sharply!
Another typical problem is dirt getting into oil channels with the cover removed. To avoid this, before starting work cover open holes with a clean rag. On engines MR20DD pay special attention to cleaning oil separator (it is integrated into the valve cover) - its clogging leads to increased pressure in the ventilation system and squeezing out the gasket.
⚠️ Attention: On Qashqai J10 with engineHR16DEbefore 2010, the valve cover may be missing oil separator baffle. If it is not there, it is recommended to install a cover from a newer version (part number11040-ED01A), since it copes better with the removal of crankcase gases.
How much does a replacement cost at an official dealer and at a service station?
Valve cover gasket replacement cost Nissan Qashqai varies by region and type of service. The table below shows current prices for 2026:
| Service type | Cost of work, ₽ | Cost of spare parts, ₽ | Total, ₽ | Opening hours |
|---|---|---|---|---|
| Official dealer Nissan | 4 500–6 000 | 2,200–2,500 (original) | 6 700–8 500 | 3–4 hours |
| Specialized service station | 2 500–3 500 | 1,200–1,900 (analog) | 3 700–5 400 | 2–3 hours |
| Self-replacement | — | 900–2 500 | 900–2 500 | 3–5 hours |
Dealers often impose additional work, such as flushing the throttle valve (another +1,500 ₽) or changing the oil (another +2,000 ₽). In fact, if you are changing the gasket preventatively (without leaks), these procedures are not necessary. However, if oil has already entered the intake tract, cleaning the throttle and crankcase ventilation valve (PCV) is really necessary.
When replacing yourself, the main costs are gasket And sealant (if required). If you take an analogue from Elring or Victor Reinz, savings will be up to 50% compared to the dealer. The main thing is to take your time and follow the instructions so as not to damage the cover or head of the block.
Frequently asked questions about replacing the valve cover gasket
Is it possible to drive with a leaking valve cover gasket?
Short-term - yes, but the risks increase with every thousand kilometers. Oil getting on the timing belt (on HR16DE), may cause it to slip or break. In addition, low oil levels due to leaks accelerate engine wear. If the leak is severe (more than 100 ml of oil per 1,000 km), it is better not to delay replacement.
Do I need to use sealant when installing a new gasket?
Depends on the type of gasket:
- Rubber reinforced (For example, Victor Reinz) - no sealant is needed, they provide the tightness themselves.
- Simple rubber (For example, Corteco) - you can apply a thin layer of sealant (Loctite 574) at the joints of half rings.
- Cardboard/paranite (found in non-original kits) - sealant is required.
Important: the sealant must be anaerobic (does not harden when exposed to air) and is compatible with oil.
How often do you need to change the valve cover gasket on a Qashqai?
There is no scheduled replacement period, but there are recommendations:
- Original gasket: 100,000–120,000 km or 5–6 years (depending on operating conditions).
- Analogues (Elring, Victor Reinz): 80,000–100,000 km.
- Budget analogues (Corteco): 50,000–70,000 km.
In Russian conditions (temperature changes, aggressive environment), the gasket should be checked every 30,000 km, especially if the engine often runs at high speeds.
What should I do if after replacement the gasket leaks again?
Causes of repeated leakage and solutions:
1. Cover bolts overtightened → Loosen them and tighten them to a torque of 10 Nm.
2. Damaged seating surface → Check the flatness of the cover and the block head (grind if necessary).
3. Gasket defect → Replace with a gasket from another manufacturer (recommended Elring).
4. Old sealant not removed → Remove the cover, clean the surfaces and repeat the installation.
5. Increased crankcase pressure → Check the ventilation system (valve PCV, oil separator).
Can I use a gasket from another engine?
Theoretically, you can pick up a gasket from another motor Nissan with a similar design (for example, from Nissan Juke with HR16DE), but there are nuances:
- The holes for bolts and oil passages must be completely coincide.
- The thickness of the gasket should not differ by more than 0.5 mm.
- The material must be compatible with operating temperatures HR16DE/MR20DE (up to 150°C).
It is better not to experiment and take a gasket according to the original article number or a proven analogue.
