I would say almost all 4 cylinder engines (especially older models) are interference type, meaning if you timing belt goes bad, your valves go bad too.
If the timing belt breaks, the valves get bent immediately.
Before it breaks
There is no scheduled replacement on timing chains (only on timing belts). Therefore, it only needs to be replaced if it breaks.
No , the 1.6 liter 4 cylinder engine in a 1987 Toyota MR2 is not an interference engine
Four cylinder has a chain. Replace it when it breaks or has so much slack in it that it jumps timing. Replace the guides at the same time. They have wear limits.
The 2.4 liter four cylinder in a 2004 Toyota Camry has a timing CHAIN
The 2.7 liter four cylinder engine in a 2007 Toyota Tacoma has a timing CHAIN
The 2000 Toyota Camry four-cylinder is not an interfere engine. However you should replace the timing belt every 90,000 miles in order to not be stranded when it breaks.
It has a timing chain that must be replaced at 90,000 miles. This is an interference engine and as such if the belt breaks serious engine damage will occur.
No , the 2.4 litre four cylinder engine in a 2007 Toyota Camry has a timing CHAIN
The 2006 Toyota RAV4 4cyl has a timing chain.
It appears that the 1996 Toyota Tacoma has a timing belt.
