    Replacing Screen on SF455 Oil Pickup...Is this piece supposed to be in the tube or there by accident? 20180612_151012.jpg
    Looks odd. Thanks, Mart 20180612_151026.jpg

    Never Mind...I pulled it out...no wonder not enough oil was getting to Rockers.
    A lot of Pot Heads in 1970...:confused: 20180612_200326(0).jpg

    Might be more potheads today. I have yet to buy a late model American vehicle that doesn't have some crap happen in the first 14 days.

    No doubt on the low oil flow. That look like it might be the screen bypass flapper. Was their one in the screen when you removed it? I never really heard of replacing just the screen. I don't know how you can replicate the pinching the factory did around the whole circumference.

    This looks like a piece of metal off the top or bottom of the tube itself that should have been discarded during manufacturing Mike.
    Flapper was on old half clogged screen.
    ampmike@aol makes low restriction ones with Instructons. Thanks

    I have good luck using a side cutters and start unkrimping the outer edge that clamps on the screen.hook it and twist it till it's 90 degrees, walk all the way around it and remove the screen.easy to clean too.then either reuse cleaned screen or replace it and peen it back over.

    I was refering to the very outer edge.the screen has to go under it.should be easier to do with no screen in the way.

    Yeah, I ripped all but one little piece of the old screen off, then slowly pryed up the edges. Thanks Dan

    Thanks Bill....Now another pain...
    Starter that was on 455 and Rebuilt one I put on, both Grind the Front, Foward edge of the Flex Plate teeth (not the top of the teeth) about every 3rd time, before starting.
    Put 2 half sims on outside, since it sounded like too far apart, 2 more halves this Eve...No Good:(
    Boat looks Great Bill!!

    For a 455 to survive that problem all these years is almost a miracle. I can't believe rod bearings didn't start rattling years ago. Run out and play the lottery now!

    True Mike. Maybe with only 47k they only drove it locally and pressure didn't have a chance to drop too bad.
    Thank the Good Lord and Thank You for all the Imput from Everyone on here.

    Hey Mart, glad alls well! All the shims are gonna do is set the depth of the starter pinion INTO the ring gear. Are the bolts the originals' with the knurl on them? Some times they get replaced with a shouldered head bolt instead. Regardless of that, the starter needs to get moved forward maybe 1/16" or even less. It may be as simple as using a screwdriver to push it forward while you tighten it or possibly drill the mounting holes out a 1/16". Maybe Wun Fun Tung dropped it and bent the corner distorting the hole. Hmmm.

    Theres also the possibility of the torque converter shield rubbing. My S-I-L replaced mine and it ground something terrible. We played with shims for an hour before I got underneath myself and found the cover not in perfect place on the trans. Shims are rarely needed on a Buick. Check the faces and fits where the two contact for a heavy burr maybe from somebody forcing a rusted starter outa the housing (?). Lastly, as a last resort, pull the starter and roll the engine with a ratchet and inspect the flywheel teeth. Doubtful thats the problem, but ya never know! ws

    True Bill, never had to shim the 350 in 26 years. Have the cover off till I get it right.
    Since it sounded like too far away (grinding before start) I put 2 half shims on outside and started it about 20 times, No Grinding...then off ramps Grinding.:(
    But hitting the front of the FP teeth, it is actually too close like you say.
    Thanks Bill

    Run the engine and check the flexplate run out. It may be moving back and forth which explains the grinding every third starting attempt.
