What I do is use a screw driver to "punch" the filter on the bottom/side edge, let the filter & oil fully drain, then stick the screw driver back in and use it as a "handle" to spin the filter off. New filter is clean, so usually not an issue to get it tight with just bare hands.

That works in a pinch. Done it many times. When my new strap wrench gets here, I'll make sure it's good and snug.

Sweet sweet victory is mine.

So a bit of back story, a few months ago, I starting hearing really bad knocking/rattling/noise from the back end. It truly sounded like a heat shield was loose, or maybe a muffler stay. Anyhow, I had it up on a lift some time ago and pryed various things and found nothing loose. It sounds terrible in the parking garage at work, because low speed, and enclosed garage makes the noise like a bazillion times worse. Functionally, I experienced no issues. It was driving me mad. So much that I took it to 3 different mechanics (my trusted one included) and they couldn't hear it, or figure it out. I live in indiana, so weather has been a bit nuts for me lately, so diagnosing myself isn't possible in the cold because my garage just barely fits my honda accord - much less the burb. So it was 58 yesterday and about 60 today, so it was time to tackle all the little things I needed to do on the burb, including finding this noise. My mechanic who replaced the torque converter last week thought it was maybe the shocks, and I should note I put brand new billsteins on....when you might ask? oh about a few months ago. See where I'm going with this?

I get the rear jacked up and pull off the wheel, and when I throw my box end on the inside nut, it was loose. Like really freakin loose. The bolt rattling around inside the mount, mind you...not the nut. So I heave and ** and get the nut and bolt out and remove the shock. I place the replacement shock that I had grabbed in there, and it was a loose as the billstein. Hmm. So I go to the bolt and nut, and sure enough, the nut only gets about 1/2" onto the threads before completely locking up. It was like it was cross threaded, but it wasnt. Corrosion, etc I'm sure is gumming up the threads. Anyhow, I throw the bolt in the vice, and run the nut up and down bolt a bunch of times until its nice and smooth, and drop a little kroil on it during reinstall. Popped the billstein back in, tightened up all the bolts with their new found smoothness, and boom problem gone. I'm glad it was a simple fix, but duhhhh why didnt the mechanics find it!?

I also replaced the front ball joints per my expectations. Remember to lower the car before you grease your joints folks.....dont ask me how I know :cool:

I use the strap wrench only to loosen it. I don't use anything except my hands to tighten it. They are only supposed to be installed until the gasket touches (no wobble when screwing in) then 3/4 - 1 full turn past that.

I am always skeptical about leaving it so loose. I'm worried it will fall off and ruin my engine when it doesn't have oil. I hand tighten it, then use the wrench to give it a few more turns. Maybe 1/2 a turn or a bit more. I've put it on too tight once.....the screw driver trick didn't even work. I barely got it off without shredding it.

Leo looks like u could have a dual alternator bracket. Not that I’m saying it definitely is but looks like it. Unless a previous owner had to relocate a pulley for something like a supercharger.

I chose my words carefully. Snug, not tight. If it's over-tightened, it can leak around the gasket.

My daughter just had to have the engine in her car replaced by a "mechanic" who didn't properly tighten the oil filter when he changed her oil. I don't trust hand tight. That's especially true on the LS, where I can't really even grip the filter very well with my big, fat hands because so much of it is shrouded by the oil pan.

Instructions on the oil filter or box say 3/4-1 turn past gasket contact.

I've been doing my filters hand tight (using 1 hand, usually only gets about 1 turn past gasket contact) on all my vehicles for 30 some-odd years with no problems or leaks.

Here's a discussion about this over on bobistheoilguy.com
