If you have problems with sealing your valves, we have one pretty efficient solution in this video. It is presented by the YouTube channel – Jafromobile. He gives a full rundown on a basic valve job technique. It features cleaning the seats, cleaning the valves, the combustion chamber and also lapping the valves all to make a more efficient seal. He covers the process from the beginning to the end. The good thing about this tutorial is that this exact process can be used for any non-rotary combustion engines. However, this process takes perseverance and patience in order to do the job efficiently.
Nevertheless, anyone can do this basic valve job. For service limits and measurements you will need to check your service manual. However, everything else can be found in this video. If your problems are bent valves, you can notice that quickly after you put one in the drill. You will notice the valve wobbling around while spinning. The evidence of this type of damage can be seen on the seat valve. If it`s too bad, you can notice damage right on the guides of the valve that comes in the form of missing pieces or cracks where the guides of the valve protrude right into and out of the head ports.
