1995 SSEI bonneville.

My oil pan gasket leaks a bit. I want to buy another to change it while doing my next oil change but it seems I have to know if I have a windage tray of not. Anyway to tell without dismantling the oil pan?

Also, what is the right torque for these bolts?

Thanks a lot!

You should have the plastic tray on the gasket. I only see the tray built in to the aluminum oil pans.

Should be 125 inch pounds. Snug them, then half torque in a cross pattern. Then full torque in same cross pattern. Then check all bolt torque again.

sorry, don't know if it'* cause' i'm stupid or not english but I don't understand what is what

Can't say for sure if you have 1st design or 2nd design. This is the one with the windage tray.

Looks like it depends on when in the year the car was built. One gasket is for 95 and before, the one with a windage tray is used in 95 on.

Ok, the tray would be in the gasket. That'* the part I didn't understand. Thanks.

At worst, would it be a drama to use a non-windage tray on one that had it and vice versa? It'* just to prevent oil pressure loss during cornering?

I'll finger the oil pan drain hole to check if I feel a tray next oil change, I'll change the gasket on the next, next one
