Nissan Almera G15 (also known as Nissan Pulsar or Nissan Tiida in some regions) is a popular sedan with engines HR15DE (1.5 l) and HR16DE (1.6 l), which inherited design features from Renault-Nissan. One of the common problems with these engines is oil leakage through camshaft oil seal - a part that over time loses elasticity and begins to leak lubricant. In this article we will look at how to choose the right oil seal according to the article number, recognize the symptoms of wear and replace it without errors.
Owners Almera G15 Often faced with two scenarios: either the oil seal “sweats” (minor oil leaks), or an active leak is observed when, after an overnight stay, a puddle forms under the car. In both cases, the problem cannot be ignored - oil gets onto the timing belt, reducing its service life, and in advanced cases can lead to belt breakage and bending the valves. In this case, replacing the camshaft oil seal with Almera G15 - an operation of medium complexity that can be performed independently if you have the tools and knowledge.
Original articles and analogues of camshaft oil seals for Nissan Almera G15
For engines HR15DE And HR16DE (installed on Almera G15 2013–2019) supplies original camshaft oil seals Nissan under the article 13510-4M50A. This part is suitable for both intake and exhaust shafts, since their diameters are identical. However, duplicate numbers are often found in catalogues:
- 🔧 Original:
13510-4M50A(Nissan) - price ~1,200–1,500 RUR. - 🔄 Analogue from Corteco:
22014010- a popular budget option (~600 ₽). - 🔄 Analogue from Elring:
547.310— German quality (~900 ₽). - 🔄 Analogue from SKF:
VKDA 35636— premium segment (~1,100 ₽).
Important: when purchasing, check compatibility using the vehicle’s VIN code, since depending on the year of manufacture and sales market (Europe, Asia, Russia) minor modifications may occur. For example, for Almera G15 with engine HR16DE (110 hp) fits the same article as for HR15DE, but some catalogs indicate an alternative number - 13510-4M51A (only the packaging differs).
⚠️ Attention: Do not confuse the camshaft seal with the crankshaft seal! The latter has an article number 13510-4M50B and significantly larger in size. Installing the wrong part will lead to oil starvation and engine failure.

Signs of camshaft seal wear: when is it time to change?
Camshaft oil seal on Nissan Almera G15 rarely fails suddenly - usually it is a gradual process that can be diagnosed by indirect signs. The main symptom is oil smudges in the area of the timing cover (on the belt side). However, there are other “bells and whistles”:
- 💧 Oil on timing belt — if upon inspection it is clear that the belt is covered with an oil film, this is a direct indication of an oil seal leak. In this case, replacement cannot be delayed: the oil corrodes the rubber of the belt, which can lead to its breakage.
- 🔥 Burnt oil smell — when lubricant gets on the exhaust manifold or other hot parts, a characteristic burning smell appears from under the hood.
- 📉 Oil level drop — if between oil changes you notice that its level is decreasing faster than usual (in the absence of other leaks), check the seals.
- 🔊 Extraneous noise - in rare cases, a worn oil seal can cause a slight whistle or squeak when the engine operates at high speeds.
For an accurate diagnosis, it is enough to remove the upper timing belt cover (it is secured with 3-4 bolts) and inspect the space around the camshaft pulley. If there is an accumulation of oil or dirt, the oil seal must be replaced. On Almera G15 with a mileage of more than 100 thousand km, it is recommended to check the seals every 20–30 thousand km, even if there are no visible leaks.
- Every 10 thousand km
- Every 30 thousand km
- Only when a leak occurs
- Never checked
Step-by-step instructions for replacing the camshaft oil seal with Nissan Almera G15
Replacing the camshaft oil seal with Almera G15 requires removing the timing belt, so if you do not have experience working with the gas distribution mechanism, it is better to entrust the procedure to professionals. However, if you have the tools and are careful, you can perform the operation yourself. Below is a step-by-step algorithm:
- Preparation: Place the car on a flat surface, secure the rear wheels, jack up the front right wheel and remove it. Also remove the engine protection (if equipped).
- Removing the timing belt: Clear access to the timing cover by removing the alternator belt and other interfering elements. Then remove the upper and lower timing belt covers (10mm wrench bolts).
- Camshaft fixation: Rotate the crankshaft until the marks align (on the crankshaft pulley and the cylinder block). Secure the camshaft with a special clamp or a handy tool so that it does not turn.
- Pulley removal: Unscrew the camshaft pulley bolt (you will need a 17 mm socket and an extension). Remove the pulley - underneath you will see the oil seal.
- Replacing the oil seal: Pry out the old oil seal with a screwdriver or puller, clean the seat from dirt. Press in the new oil seal evenly, without distortions, using a mandrel of suitable diameter.
- Assembly: Install the pulley, tighten the bolt (tightening torque - 80–100 Nm), check the timing marks and reassemble everything in reverse order.

Critical moment - correct installation of the oil seal. It must fit into the seat without distortion, otherwise the leak will resume after starting the engine. Also pay attention to the condition of the timing belt: if there are traces of oil on it, the belt must be replaced, even if its mileage is short.
⚠️ Attention: When removing the camshaft pulley, never use a chisel or hammer - this may damage the keyway or the shaft itself. If the bolt does not come off, use a penetrating lubricant (such as WD-40) and a lever with an extension.
Before installing a new oil seal, lubricate its working edge with a thin layer of engine oil - this will make the first fit easier and prevent damage to the rubber.
Common mistakes when replacing a camshaft oil seal and how to avoid them
Even experienced craftsmen sometimes make mistakes when replacing oil seals, which leads to repeated leaks or more serious breakdowns. Here are the most common mistakes and ways to prevent them:
- 🔧 Timing timing marks mismatch - if after assembly the marks on the crankshaft and camshaft do not match, the engine will run unstably or will not start at all. Always secure the shafts before removing the belt!
- 🛠️ Damage to the seal during installation - pressing by eye or with a distortion leads to deformation of the rubber ring. Use a mandrel or old oil seal as a guide.
- 🧹 Dirt in the seat — if the groove is not cleaned of old oil and deposits, the new oil seal will not fit tightly. Wash the installation area with gasoline or a special cleaner.
- 🔩 Loose pulley bolt — weak tightening leads to pulley runout and accelerated wear of the oil seal. Tighten the bolt with a force of 80–100 Nm.
Another common mistake is ignoring the state timing cover o-ring. If it is worn out, oil will leak not only through the oil seal, but also through the junction of the cover with the block. When replacing the oil seal, it is recommended to simultaneously update this ring (part number - 13070-4M500).
What to do if the leak does not stop after replacing the oil seal?
If oil continues to leak after installing a new oil seal, check:
1. **Part quality** - defective oil seals (especially cheap analogues) can leak from the first days.
2. **Camshaft Condition** - If the shaft has deep grooves or corrosion, the seal will not be able to seal the joint. In this case, the shaft will need to be ground or replaced.
3. **Pressure in the lubrication system** - increased oil pressure (due to a clogged oil filter or faulty pressure relief valve) can squeeze out the oil seal. Check with a pressure gauge.
4. **Leaks through other components** - sometimes oil does not flow through the oil seal, but through the valve cover gasket or camshaft sensor. Inspect the engine carefully with a flashlight.
Cost of replacing a camshaft oil seal: do it yourself vs service
The cost of replacing the camshaft oil seal is Nissan Almera G15 varies depending on region and service level. On average, expenses are as follows:
| Service/Part | On your own (₽) | Service (₽) |
|---|---|---|
| Camshaft oil seal (original) | 1 200–1 500 | 1,500–2,000 (with extra charge) |
| Timing belt (if replacement required) | 2 500–3 500 | 3 000–4 500 |
| Work (replacing the oil seal) | 0 | 3 000–5 000 |
| Work (timing belt replacement) | 0 | 4 000–6 000 |
| Total (minimum) | 1 200 | 4 500–7 000 |
As can be seen from the table, self-replacement allows you to save up to 5,000 ₽, but only if you have a tool and experience working with timing belts. If you've never removed the timing belt, the risk of error (such as broken timing belts) outweighs the savings. The service charges from RUB 3,000 for this operation, but they guarantee correct assembly.
Advice: If the car's mileage exceeds 80–100 thousand km, it is advisable to replace not only the oil seal, but also timing belt, rollers And pump (if it is driven by a belt). This will increase the cost of repairs by 5–7 thousand rubles, but will eliminate the risk of belt breakage in the future.
Savings on replacing the oil seal can result in expensive engine repairs if the timing belt breaks due to an oil leak. Always evaluate the risk/benefit ratio.
Alternative methods for eliminating oil seal leaks (temporary measures)
If a camshaft oil seal leak is discovered on the road or you do not have the opportunity to replace it immediately, you can use temporary measures. They won’t solve the problem completely, but they will help you get to the service:
- 🧴 Sealant for oil seals - special additives (for example, Liqui Moly Oil-Verschluss-Stop) temporarily restore the elasticity of rubber. Add the additive to the oil according to the instructions.
- 🧰 Pulley bolt tightening - sometimes a leak occurs due to a loose pulley. Tighten the bolt with a force of 80–100 Nm.
- 🧹 Cleaning and blowing — remove oil from the surface of the oil seal and timing belt using carburetor cleaner, then blow off with compressed air. This will not eliminate the leak, but will reduce the risk of oil getting on the belt.
It is important to understand that these methods are temporary nature and do not replace a full repair. For example, sealants for oil seals last 1–2 thousand km, and then the leak resumes. In addition, some additives can negatively affect the properties of motor oil, so after eliminating the leak, it is recommended to replace it.
⚠️ Attention: Do not use silicone sealants or adhesives to “reanimate” the oil seal! They are not designed to operate under high temperatures and pressure, and their particles can clog oil passages.
FAQ: Frequently asked questions about the camshaft oil seal Nissan Almera G15
Is it possible to drive with a current camshaft seal?
Short term - yes, but with caution. If the leak is minor (the oil “sweats”), you can drive to the service center, checking the oil level. However, if oil actively leaks out or gets on the timing belt, the operation of the vehicle prohibited - this can lead to belt breakage and valve bending.
How to distinguish a camshaft oil seal leak from a crankshaft oil seal leak?
A camshaft oil seal leak manifests itself as oil smudges. at the top of the engine (from the timing belt side), and the crankshaft oil seal flows into bottom part (from the flywheel or generator pulley side). Also, when the crankshaft oil seal leaks, oil often splashes onto the crankcase protection.
Do I need to change the timing belt when replacing the camshaft oil seal?
A must if there are traces of oil on the belt! Oil corrodes the rubber of the belt, reducing its strength. Even if the belt mileage is low, it must be replaced. If the belt is clean and less than 3-4 years old, you can leave the old one, but this is risky.
What tools are needed to replace the oil seal?
Minimum set:
- Heads for 10, 17 and 19;
- Torque wrench;
- Flat blade screwdriver;
- Oil seal puller (or suitable mandrel);
- Camshaft retainer (can be made from a metal plate).
You will also need a new oil seal, timing belt (if necessary) and cover sealant.
How long does it take to replace an oil seal?
The service work takes 2–3 hours (including removing/installing the timing belt). If you replace it yourself without experience, it may take 4-6 hours, especially if there are difficulties with unscrewing the pulley bolt or aligning the timing marks.
