I supose you have an Apple Galaxy S4 phone too. and your other car is a Mercedes M3. I dont think even Google can help you.
Straight 6 cylinder motors have timing chains.
Wow... that's a rare item there! A four-cylinder six-cylinder???
Read my other answer for advice.
It cannot be a four cylinder straight six. It is either a four cylinder , or a straight six cylinder. Which is it?
A 4 STOKE STRAIGHT SIX. THE TIMING CHAIN SHOULD BE VERY SIMILAR IF NOT THE SAME.
