Here is a pic of the 2000 bonneville pan and oil filter adapter that is on my 97 bonneville. The 95-97 are completely the same subframe and body.with different outter fenders.



And in the car



Overall it'* a better setup than your original setup because you no longer take off the oil filter over the subframe.

As long as your pieces look like this, I would leave them on the motor.

I forgot to mention one thing.



See the top of the oil filter adapter where ti bolts to the timing cover. There is a metal hunk that sticks straight up. It has no reason or value. Cut it flush. Your power steering pump won't fit with that hunk in the way. I cut mine in the car after realizing the piece was in the way.

Heres a closer pic with it cut off. (Don't ask why it was back out and I won't tell the tale of 3 motors)

Billboost - Thank you very much - any possible way I can give you a call and ask you a question or two ???

Or if you could give me a call @ 612-483-1495 ... I would appreciate it !

My main concern at this point is the harmonic balancer. Can I leave the one that came with the motor on ??? Im gonna stick with the new style oil pan.

yes leave the balancer on.

I'm on Eastern time here. Will pm you my number...I'll be able to talk after about 12 noon here today. for a bit, until I get to the Lasik office. then will be available again afterwards.

Assuming it is good, DEFINITELY use the harmonic balancer that comes with the replacement engine. HB'* take a "groove" where the front cover crank seal touches them, and if you swap one used HB for another you run a great risk of leaking at that seal.

Also, as Bill said, check on the flywheels. A 2000+ LeSabre will have a 258mm torque converter bolt pattern, I do not know whether the 1995 Bonne is 258mm or 245mm.
