Today I went to the garage and started replacing the valve cover gaskets.
Spare parts on the photo: 1121446011 , 121910First you need to thoroughly rinse, clean and blow all contact surfaces, then degrease everything with a solvent.
First, we insert the gaskets into the valve covers, then we coat the head with a thin layer of black sealant, especially pay attention to the places where the camshafts stick out, there is a leak in the corners if the gasket does not fit tightly. Then put the covers back in place. I bought new bolt washers and used a special blue thread locker, since everyone knows the problem of jets, when the bolts are unscrewed from vibration and the oil starts to slip through the gasket, from this the candle wells are usually 5 and 6 cylinders filled with oil (
Tighten the covers evenly from the middle to the edges, first crosswise, and then clockwise to the desired force.
Also, new coil tips were bought in advance, as well as new chips, since another weak point of turbo jays is that all top tubes, as well as coil chips, literally turn into dust from high temperatures. And when you start to take off the chips, they just crumble in your hands) Here is the chip part number 90980-11246 .

Thank you for your attention) It remains to put the pan on the sealant, clean the intake manifold and replace the crankshaft oil seal and you can drive the car))

well, the main thing is to tighten it normally and at the same time not to break the thread, otherwise your health is damn good))
no, I tightened the lids by hand to a certain effort, you just need a skill)) And so you can look at the book and see with what effort they stretch)
Every time I learn something new) Very informative) I will take into account the blue bolt lock. And the question is, did you tighten the head with a torque wrench?
Here, it’s like a thread lock, it’s not quite a sealant, more like a glue)) It’s just blue in color - it’s removable, but there’s no red)) And I use gray as the main sealant, it’s the highest temperature and high quality, well, it’s also black, for example, for intake and places where temperatures are lower
