Question about 2002 Mazda Protege
Three sizes of pistons are available:
2. Over size 0.010 in (0.25 mm).
3. Over size 0.020 in (0.50 mm).
Over sized pistons and rings are widely used in all automobiles with no trouble at all. They last for more than 200,000 km, provided if the engine oil, oil filter and air filters are replaced at the recommended intervals.
The most important point to consider here is to maintain the oil clearances between the various parts during the machining process.
For example piston to cylinder clearance, crankshaft to main journals and big ends clearance, valve to guide clearance, at room temperature. Then comes cleaning process and the engine assembling process.

SOURCE: I need the timing marks
please forgive me but as iam getting older my memory isnt what it was but i seem to remember two slots in the back of the cam but it could be a mark on the rear cam cap,if not sure here then do it with no timing marks -- its easy make sure no1 piston is down halfway so valves clear pistons then look at the cams and start with the inlet no1 which should be just closed and the cam lobe moving away from the tappet ,and now the exhaust will be coming around to make contact with the tappet ,then look on the cam /cam caps keyway or whatever for anything resembling the timing marks .Sorry i just do so many makes of vehicle i cannot remember them all i just use my 6 yrs or motor vehicle technicians course ,although its all out of date now the basics are still the same and i apply this basic to any vehicle and it always works .right last question this one iam off to cultivate the garden and relay my irrigation pipes
