Replacing the Valve Cover Gasket on the Lacetti

Replacing the Lacetti valve
cover Replacing valve cover gasket. It took me less than an hour to replace the valve cover gasket. Replacing the valve cover gasket on a Chevrolet Lacetti. Oh, so I did it.

The valve cover gasket needs to be replaced if there are oil leaks around the perimeter of the valve cover and, worst of all, if this oil has already leaked into the spark plug wells.

What do you need to replace the valve cover gasket?

• 10 mm socket wrench
• pliers or a screwdriver (depending on what kind of clamps are on your Lacetti)
• better than a torque wrench. If not, then you can do without it

• In fact, the gasket itself.
• Sealant. Many “foaming at the mouth” argue that silicone cannot be used, since it can “poison” the oxygen sensor. This statement does not entirely correspond to reality. There are different types of silicone sealants. Therefore, buy one with the inscription on the tube: “Safe for oxygen sensors.” Or you can find it by the smell of the sealant - there should not be a corresponding aroma of vinegar, and in the standard - there should be no aroma at all! Typically, auto sealant manufacturers no longer create silicones that are unsafe for sensors. If you are still afraid to use silicone sealants, then take any others. But I still decided on silicone sealant - they have a lot of advantages over others, starting from the best adhesion and durability and ending with the highest degree of elasticity, which makes it possible to use it also on movable structures, without compromising the quality of sealing of joints . Also read the instructions so that after hardening, the sealant can withstand high temperatures.
• sealing rings for bolts – 15 pcs. 8th grade Engines 1.4-1.6 (k7m and k7j) were installed not only on Logan but also on Sandero, Symbol, Kango, so if removing the intake manifold or replacing the gasket of this manifold is required. You can use KAMAZ ones, snow-white ones made of silicone. Let's say I found reddish silicone rings. I don’t even know what they are made from, but they are several times cheaper than the unique ones.
• It’s better to immediately buy a couple of bolts in reserve, so as not to have to run to the store again later, because they are not at all difficult to break!
• some kind of detergent for cleaning the valve cover. I had this. Fast and comfortable.

A simple method of applying sealant without a gun

First you need to prepare everything you need, namely:

• Molar tape;
• Soft napkins, cloths;
• Spray bottle with soap solution;
• Solvent;
• Rubber or plastic spatula (for adjustment work);
• Sealant;
• Medical syringe 20 ml;
• A block, a stick, a pipe for squeezing out the product.

Before application, it is recommended to degrease the surface thoroughly using a solvent. After which the area near the future seam is covered with masking tape.

To squeeze out sealant without a gun, you will need the tube itself, a syringe and some kind of bar (it should be smaller in diameter than the container).

Next you need to do the following:

1. Pull the rod out of the syringe;
2. Cut off the tip of the sealant tube;
3. Place the block on the floor (its length should be sufficient, about 20 cm);
4. An open syringe is applied to the end of the balloon and the product is squeezed into it using the tube resting on the bar.

Then you can easily work with the sealant from the syringe by inserting the core into it. It may be even more convenient than using a standard thick tip.

In addition to the block, you can use any other available material. Possibly the remains of some pipes. A suitable “support” can be found in every home.

The sealant must be applied evenly. The required amount of substance must be applied at one time. Next, the product is lightly sprayed with soapy water to form an even seam.

Using a spatula, the sealant is distributed over the surface to fill voids. The movement should also be continuous and calm. Moderately soft. It is important to maintain the angle of position. If the line is interrupted, the alignment process begins again.

When everything has turned out nice and smooth, carefully remove the masking tape and wipe off the remaining sealant with napkins.

From the above, we can conclude that the lack of a gun for squeezing out sealant is not an obstacle to its use. It is quite possible to cope with the materials available in every home.

4. Disconnect the wires from the spark plugs and put them aside.

5. Next you need to remove the air filter housing and the upper timing case. Audi a6 c5 valve cover gasket repair and replacement. But I don’t do this, he doesn’t really interfere. It’s just that when you put the cover in place, the timing case will need to be pulled just a little to the left. We tear off the old gaskets, the reinz valve cover gasket previously replaced the block. Now let’s figure out how to replace spark plugs on a 16 valve prior. To do this you will need a spark plug wrench, a screwdriver and a socket wrench. I do this without problems. If you can't, then remove this cover.

How to apply silicone sealant

The most common is silicone acriplast. Silicone sealant is easy to use. It can withstand sudden changes in temperature and high humidity, so it is often used for sealing work in the bathroom. In addition, it contains special antiseptics that prevent the spread of fungal growths and mold.

Application will not be difficult, since silicone sealants are available in convenient tubes. They should be placed in a syringe or applied directly from a container.

The rules for application are the same as for other products. But some features should be taken into account.

Complete drying of the composition occurs after two days (the indicator depends on the thickness and depth of the seam). Although the surface appears dry after an hour, it is prohibited to put it into operation. There should be no direct contact with water during drying.

Causes of failure

Replacing the valve cover gasket on Chevrolet Lacetti 1.4 and 1.6 is completely identical, and the causes of the malfunction are the same. The main cause of leakage from under the valve cover is poor-quality rubber from which the gasket is made. According to the manufacturer, it should withstand heavy loads, but in practice it becomes damaged after only a short period of use. The drivers themselves often help speed up the process.

With constant engine overheating, gasket deformation increases. The manufacturer recommends replacing after 80,000 kilometers, but almost always, you have to do this much more often.

Tools

To work, you will not need many tools; almost all of them are available in the arsenal of every car enthusiast:

• Slotted screwdriver;
• Head 10;
• Open-end wrench 10;
• 2 ratchets, regular and with a dynamometer;
• Pliers;
• Alcohol;
• Sealant.

Article on the topic “Which sealant is best for the valve cover.”

In principle, you can do without a dynamometer, but then when you tighten the bolts securing the cover, there is a risk of tearing them off. Also, after removal, check the condition of the bolts. If they are longer than expected, then it is better to buy new ones. It is better to use sealant without silicone. You can distinguish them by the inscription on the packaging. Also note that silicone sealant has a strong vinegar smell. If you could not find a high-temperature sealant without silicone, then it is better to do without it.
