Here is the cylinder head of a Renault 1.5 k9k. This engine has a known problem, and it occurs when the timing drive breaks, resulting in the valves being bent and the camshaft mounting brackets being broken. The camshaft itself is often bent. So in our case, as we can see, the valves, at least the exhaust ones, are definitely bent. And three brackets are broken. This is what is visible visually. I will disassemble, inspect, and look. It feels like the shaft is bent. But this can be deceiving. I will measure and see if it is bent or not. I will unscrew the brackets. Please note that the bolts of the brackets are also bent. We will change them all. The main thing is that the threads of these bolts are not pulled. They may have to be restored as well. Well, out of 6 brackets, 3 are broken, the rest are fine, with no signs of possible cracks. I pull out the shaft. It is difficult to understand anything yet. The camshaft seal is oak. The tappets in this head have also come to an end. Apparently, no one has climbed here for a long time. They are specifically worn out, frayed. Another, so to speak, detail in the order of spare parts. I take out the tappets and put them aside, this is already garbage. I release the cylinder head spring compressors. I will loosen the crackers with a magnetic spring compressor, and then disassemble them further with a clamp. I remove the springs. I look at the intake and exhaust springs and compare them by wire diameter, spring diameter, height, winding frequency, in general, we look for differences. On this head I know that they are the same, but I constantly pay attention to it, so that you get used to paying attention to it. I extract the springs and plates. Now I will examine the valves. They are difficult to extract, so I will help myself with a duralumin mandrel. Now they can be extracted without any problems. The exhaust valves are sharply bent, apparently the owner tried to ride his iron horse to the last. I could not pull out two valves. But, I forcefully knock them out with a punch. I will still change all the guide bushings, the client has already purchased them in advance. The seats have moved apart, but in this case it is not critical, they are not sagged and in the future I will restore the chamfer on them. The surface milling is factory, apparently nothing global has been done to it yet. I remove the valve seals. They are just plastic, which confirms my guess. I remove them all. I will look at the bend of the intake valves. Everything is clear with the exhaust. As a result, 2 intake valves are not bent, and 2, unfortunately, were hit. I'll take one unbent intake valve, measure its leg for wear. For the sake of interest, I want to feel the clearance in the bushings by tactile sensations. What is it here at 300k mileage. The wear is not great. Only 100. I'll clean the HV from oil and other contaminants with kerosene and a brush. I'll blow it out, blow off the kerosene. The result is that the wear in the bushings, let's say, is not great. On a five-point scale, it's a four, and in other circumstances, the guides could not have been changed. And here are the customer's spare parts. Spare parts from Frecia are a very good option, by today's standards. 8 HV, camshaft oil seal. Valves. This is the exhaust. Good processing. Leg 5.96. I'm looking at the intake. Everything is the same. And what is interesting is that the leg size is also 5.96. The package also contains the HV seals, and a new camshaft is separate. I will look at the camshaft. I will measure its journals. Well, that's it. The shaft bend is almost a millimeter. The client ordered a set of brackets in addition to the purchased spare parts. Previously, they could be purchased without problems. However, a week later the owner gave up - he could not find them. He asks that we make them ourselves. There is a sample. The sample will be the bracket THAT SURVIVED. Vitaly, a boring machine operator, gets to work.
