Easy enough to drop the pan in driveway done it.for several friends 1 bad o ring 2 sludged pick ups . And usually.all the.additives just reliquify sludge and move it into pick up

The pan isn't the problem, it's having to drop the front diff that has me avoiding it.

You just unbolt a few bolts and hang it no need to completely remove

I'm not sure you're going to find the oil pump by dropping the pan anyway; is it not behind the timing cover on the Vortec"s?

Pretty sure the pick up tube connection can be accessed. I wouldn't attempt to change the oil pump myself.

Well, I bought the pick up tube and o-ring and will attempt it over the holidays.  I have a hoist lined up and a little help. Fingers crossed that this is the problem and I haven't done too much damage. Also hoping that the oil pan gasket is reusable.

There's a lot of times the pan gasket is or looks reusable; but what the F%$* get a replacement. You're going through all this work and then taking a chance on a used used gasket?

Hey look at this, the oil pressure is great; to bad it's now a butter ball turkey. Leaking enough oil to be self basting. 

Sorry.

It's good to cut corners but only in the right places!

The oil filter housing is integral with the pan lots of oil pressure goes through that gasket area I would heavily suggest a new gasket

Yes, I took the advice and bought a new gasket.

So, the pick up was pretty gummed up, but the o-ring didn't seem that bad. Changed those out, but maybe only made a little difference.

Just thought I would update you all on the state of the truck. I drove it all winter and it's still running. Just changed the oil again and it's purring. Geez. maybe there is some small channel plugged, preventing a good pressure reading or that little filter screen under the pressure sensor was shoved down inside previously and it's blocking something,

I do hate not being able to figure things out though.

Another update.  So after driving myself crazy for what seems like years, I finally changed the engine and everything is great.  The original engine was just tired and worn out and finally on its last legs.  I appreciate all the input from everyone on this post/issue. Changing the engine was cheaper than replacing the truck.

    • 2 stroke oil vs healthcare

      Was down in South Carolina this past week and decided to stock up on some oil for the outboard for this year. Last year I paid $58 a jug for quicksilver (TC-W30) approved oil. Other option is Mercury's oil, yamalube (if you can find it) or Amsoil. All typically over $60. I think there was a dealer in Huntsville that was selling cases last year for $48 a jug of mercury if I can remember correctly. Anywho, headed to walmart and got pennzoil XLF for $17 a jug! I get it, we have healthcare

    • 4 stroke marine oil

      Sad day...winterized the boat today. Had a tough time finding 10w30 4 stroke marine oil BUT I saw tons of 25W40 4 stroke marine oil. I had never noticed this type of oil before. Is this what is being recommended now for 4 stroke engine oil? I did find eventually some 10w30 and bought it but was surprised how much of the other I was seeing (maybe there was so much because nobody buys it!) My engine is a 90 hp Yamaha 4 stroke from 2013 if that makes any difference.
