Yes, thats what I am saying that it is better to spend on timing chain rather than suffering a huge dent on the pocket as a consequence of the damage repair due to a broken chain. Same here. I have been using Delvac1 at one point of time inspite of a leak in the oil sump and losing quite a costly oil. But the preventive care should be justifiable. Here, my point is that the recommendations are being made at a few service centres by merely looking at the odometer readings. Even if we say that they are honest in recommending the timing chain even in 75HP as a preventive measure/care at 60,000Km, why in that case do they say that the timing chain is making noise so please change it. If someone recommends a change of timing chain by merely listening to the noise of it, then the noise should be more than normal for sure. I showed my car to 2 other FASCs and 1 other mechanic and none of them found any abnormal noise of the timing chain just like I was suspecting. Thus, I conclude that the justification for changing the timing chain wasn't valid.
