Hi,

Let us not forget the timing belt tensioner and the flame trap cleaning.
It’s an important part of the crankcase breathing system.
You might get premature oil seal leakage, of which, helps eat up timing belts.

These are routinely done with tick marks coinciding in-line with oil changes.
Next thing is how often are oil changes, when Volvo went to 7,500 mile intervals in the mid eighties.

3,000 mile intervals are too often with today’s oils unless, you let it sit for years, to get a measly 3,000 miles.

Even coolants go five years or a 100 - 150,000 miles and matchup to water pump replacements.
So two timing belts and one water pump, maybe some oil seals on the side!

Jeez, I’m starting to sound like a menu in a restaurant!
Tips anyone?

Phil
