POint well taken,BUT,, when its time for tin foil, its just TIME! A guy can fake it on the paper towels,, heck, dish rags work,, in a serious enough bind, there are things that CAN be used in place of toilet paper, but tin foil? Man,, when its time for a hat, its just time & there IS no substitute I am aware of,,
Is this or is this not a classic case of thread drift?

Back to important topics.  I started up the s40 when the temp got up in the high 60s one afternoon.  The noise was significantly less.  When the engine noise was at it's worst the highs were 45 - 50.  Would that be indicative of a valve issue?  Thanks.

Some times the noise is almost nonexistent.  And sometimes it comes and goes.  I dumped the oil and put in Rotella 15-40.  It made everything feel a lot smoother.  Does anyone have any thoughts?  Thanks.  I'm waiting for a day where the highs are decent to pull everything apart.  It gets old wrenching on it under the car port when it is 45 out.
