What makes a vehicle jump timing? and what can be done to prevent it ?

Question

on a Mazda B2000 pick up truck

Answer 1

Generally, correct maintenance will prevent this problem. There are two types of timing required to make an engine run. They are ignition timing and valve timing. Valve timing is absolutely critical and 1 or 2 % error will prevent the engine running. You don't specify what year your truck is but I would imagine it has a timing belt that regulates the valve timing. This belt is automatically tensioned and should be replaced every 100 000kms (62,500 mls). Lack of maintenance and replacement or faulty tensioners, oil or water contamination of the belt will all run the risk of loss of timing and severe damage to the engine. (pistons hitting valves at high speed). Ignition timing is far less critical and in your case it is governed by the distributor. If it slips it is generally some mechanical fault with the distributor or its drive mechanism, or it is frequently set wrong. Jules, Automotive lecturer, Australia.

Answer 2

A bad timing belt. Replace It. We are required to change ours every 60,000 miles. Have you called Mazda to see when you should change yours?

Answer 3

Assuming its a OHC motor,it would be a worn timing belt or chain.
It needs to be replaced before it breaks,which will damage internal motopr parts.

Answer 4

It nevertheless an identical - Pos to pos first and neg of host motor vehicle to a distant floor bolt or bare piece of metallic of the failed motor vehicle . The final connection is to ward off an explosion could desire to there be a spark close to the failed battery. that's the deal. it may desire to be clever to run the host motor vehicle for 5 min to grant a reasonable fee to the batt of the failed veh while it starts off? Then close the host veh OFF - to ward off harm to the pc or charging structures of the two motor vehicle while the failed veh is began and the structures could desire to greenback one yet another.

Answer 5

Replace the belt and gears and the tensioner pulley on the timing belt.
