Timing Chain Cover+Gasket Replacement for Chevy Lumina 95 3.1L V6 LS sedan
What is your question?
To replace the timing chain cover+gasket for my Lumina 95 3.1L V6, a popular repair manual HAYNES mentioned that the timing chain cover can be removed with the oil pan in place, BUT the oil pan must be removed for a GOOD INSTALLATION to seal against the bottom of the timing cover.
Could anyone with experience on Chevy engines, please explain to me if the oil pan must be really removed in order to install the timing cover+gasket and seal well against oil leakage at the bottom of the timing cover? and WHY it help stop oil leakage at the bottom?
Thank you very much.

Im retired now but I didn’t remove the oil pan - I always used RTV gasket material - clean everything up and add the gasket maker to lower timing cover where it mates to the oil pan - nary a problem....
However it should be noted that I was in the business for a VERY LONG TIME and that certainly makes a difference as experience is invaluable.
Good luck!
Thank Pushrod! your experience is definitely invaluable.
The lower timing cover also mates to the side of engine block, not only the top of the oil pan, I believe so, Should the gasket maker be applied where it mates to the side of engine block? also the timing cover gasket ( upside down "U" shape) does not cover that area! which is really strange, why?
Please let me know, thank you again.

Apply gasket maker liberally to all areas needed..
