[Solved] Peugeot 1.6 HDI Engine: Leaking Cylinder Head & Camshaft Cover - How to Seal with Erling EL 035971

The problem concerns the 1.6 hdi engine and the leak between the cylinder head and the camshaft cover at the rear of the engine over the egr valve. The first thousand engines that I made in my life, I glued to the hermetic, now I use a similar preparation Erling EL 035971. The problem is caused, of course, the lack of flatness, the repair requires a photo of the head, which I would like to avoid. What means do you use that could be checked in a larger gap.

A colleague brings me the original silicone from Toyota black I use it in the vag group, dog
it has not let me down yet.

I use Reinz sealing compound in such a "spray", something like silicone, but decent.

You can have some numbers of these specs, I found something like an anerobic adhesive ELR ELR 777.790 a bit expensive but it will be cheaper as you undress it once again.

Try the Loctite agent "Form-A-Gasket No. 1

Sometimes a poor quality gasket, at home I changed the gaskets twice, gluing on good silicones, and the problem was solved after applying the erling gasket, not from some bushes companies. And as much as the flatness of the head or lid. After three years, she began to sweat, but supports the second engine earlier, the "bushes" lasted up to 3 months, and again there was a liquid.

In this place where the colleague Daro 122 described, the gasket does not exist.

It's like a friend of a moto-kord. When I bought a car it was made for silicone, I corrected Erling's formula similar to hermetic, now I would like to try something new I think about the already mentioned Erling preparation on the bass of an anaerobic adhesive due to the leveling of unevenness up to 0.3 mm. Tomorrow, I work, hopefully it will not break any material.

I will not wish you good luck.

Hello, I glued the month well, no leakage, now the entire back of the engine flooded. But I have another problem on my head, the oil leak from the turbocharger. The compressor is after professional regeneration on melett parts, there is power and even more than before regeneration, I gave the compressor for complaints and zonk because the compressor checked and good. Auto is Peugeot 407 1.6 hdi 110 Km, after removing the air filter - turbo, you can see that there is oil. Replaced valve cover - from it comes the pneumothorax tube, without changes, just 3 km and you can feel the oil burning. I understand that there is an exchange of rings waiting for me, or maybe there is some kind of econect that I do not know about.

If you changed the throttle and it did not give it means that there is too much pressure in the crankcase, possibly you have a poor quality or a dirty air filter.

The air filter has recently been replaced, after removing the cork, something flies, but not much. Lifting versions have a solenoid valve added, as far as I know before, they dirty a little turbo with oil.

Is a solenoid or heater?

How many kilometers have you traveled that you want to exchange rings?

It looks like a solenoid valve, I do not have it in my motor (no plug) and I have nowhere to check. As for the course, it is 207,000 on the counter.

Have you checked the compression?

I did not check the compression, there is no power, no injection corrections -0.2 to +02, touch toes, there were no turbine oil leaks before the turbo repair. Noticeably, there is more power and more blows to the crankcase and oil in the dump.

I know that the topic is annual ...
In place of the cover, a gasket is provided in its grooves. Such a rubber slightly pulling and it is enough if everything is ok with the engine.
However, if the oil gets out that way it means that there is high pressure in the crankcase. And no gluing with silicone. You have put the lid on the pressure, the oil has been stuffed somewhere in the back and the compressor. From what I have heard, the reason may be sealed rings on the pistons, something wrong with the acetules or clogged pneumothorax. The pressure can be roughly checked with an oil stopper. Idling engine, unscrew the stopper and if you lightly telepie it is all ok.

I managed somehow, some leaks under the cover, a little overpressure in the gearbox, the rides are overcome.
