so the serial number on the sticker on the timing cover is the engine number. cool, i was thinking that but wasnt sure. what put me off the number on the cover is that its 830XXX which is a very high number so i was thinking maybe its not the engine number. reason for asking is i need to know before i can order a timing belt as there are 2 different belts according to engine number. one is from 131155 on. the other is up to 131154. so u can see why i thought my number of 830XXX might have been something else as its so much higher than the change over numbers for the belts.
