Common Rail Injector Nozzle M1003P152 8AU Alen--(at)--china-lutong(dot)--net Here are some guidelines to help you pick the perfect kit. Know your purpose Figure out first what you want to do with your engine. Ask yourself some questions. What are the worn-out parts you need to replace? Do you need to tinker with the whole engine, or are only the pistons in need of attention? Do you want to make your engine more powerful? Is the engine even worth rebuilding, or is a complete replacement better? This will not only help you pick out the right kit, but also help in setting a goal for yourself with the whole repair. Measure everything Engines come in different shapes and sizes. For example, bores can be wider or narrower; camshafts can be longer or shorter compared to others. Measure all the dimensions you can find. Count also the number of parts you will need. Only a fool would buy a kit for a 4-cylinder if the engine is a 6-cylinder. These are just some of the few things you need to count before buying a set. With all these numbers in hand, refer to the suppliers catalogue to see if they have the right kit for you.
