Crisis

Good news. New 20W50 oil & new filter seems to have everything back in order. Cut open the old filter & it was clean.

Still, this is getting to be a bit tough on the heart. After the amount of $$$ I've sunk into this thing in the past 3 years, including engine work equal to the value of a new motor, I think I'd have cried if it was the bearings.

Laird..........was going to suggest moving to 20W50. We dont run our cars in the winter so I dont worry about the lower number to much.

If you can get it try 15w50 Synthetic.............thats my preference in our semi-frigid world.

ps..........look out for a gathering in mid Sept my place

I'm surprised nobody mentioned this solution to low oil pressure at hot idle....the oil thermostat springs get old and fatigue...right above the pressure sender....once I changed the springs I never got a hot idle low pressure problem..

I do think the 10-40 oil is part of your problem...but canada isn't that hot either? Since it appears you solved the problem....just buy the springs + pressure sender seal and replace it at your next oil change...

thats great that things are back to normal.
Now would you please tell what brand oil you used??

Ueed Castrol 20W50. I was the only 20W50 available in our local stores. As mentioned before, cold climate means that heavy oil is not commonly stocked.

Glad things are back to normal.

I know my cars do not like anything less than 20W50 synthetic!
