Opinions

Hi

I have a 97 w/130k. Original.
The thing is incredibly dry, no leaks at all. It has been using regular oil but I want to make the switch to synthetic. Just wanted some opinions on if I should at this point. I know there have been previous post (Ron) about making the switch. Just wondering?


Also,
How difficult is it to switch the serp belt in a 97, for someone w/ minimal tools & moderate skill.

Thanks

Serp belt is not hard to do. For you, I would suggest getting the fan clutch tools. Me, I do it with channel locks and a long screw driver. You know my views on synthetic, but I will add that if you look into the fill hole for the oil and it looks fairly clean, switching is much less likely to cause issues than if it is gummed up.

So if it is gummed up synthetic should clean it up but may cause leaks? What if I did a change every 1000miles at first would that help avoid leaks?


Thanks for the advice.

If it is gummed up, synthetic may cause leaks and may also cause sludge to be dislodged blocking oil passageways or even the pick up tube leading to other issues beyond leaks. My normal way it to switch to synthetic and change the filter at short intervals and continue to do so until the filter is no longer "heavy" (you will be able to tell). If it looks really gummed up, I would be tempted to let it idle with a quart of ATF mixed in with the old oil for ~10-15min (or more) while hot before I changed the oil to synthetic. While I would normally change the filter at 1000 miles in the case of a synthetic switch over, I would be tempted to change at 500 miles if it was gummed up. However, the early changes are only to remove the sludge and build up that accumulate in the filter, not help with leaks. Frankly, I think the leak thing is over blown, I would be much more concerned with sludge being dislodged and causing other issues. In my view, if all that is holding the oil in is sludge and low oil pressure, then you have issues that are beyond redress with any oil.
