First off, you are old enough. Second if you say you have no money to build a simple leakdown test, how do you plan on buying new crank seals. Do yourself a favor, save some money, build a leakdown tester and find out what your problem is. There is absolutely no point in ripping apart your motor, when there could be nothing wrong with it.
down here have to be 16 for a job, how can i save money if i dont have a way of getting any, parents dont even give me an allowance. I can clearly tell something is wrong if its shooting out that much smoke
