So I've been dealing with an oil pressure issue with my truck since I've bought it and decided it's time to stop messing around and fix the POS.
Basically, once the oil temp gets warm enough the oil pressure starts dropping, and then the valve train starts getting very noisy. On a hot day, I can haul my car to the track about an hour away and by the time I get there the truck is getting loud, and when I leave about the time I pull in the driveway she starts clattering. But if you shut it down and let it rest for 5-10 minutes you can restart it and it's good to go until the oil temp climbs again. It happened on a parts run last week and while it hasn't been a problem yet - I want to get it resolved.
So here are a couple of pictures of the tear-down.
-
Of course, the center/drag link was a complete pain in the ass to remove. One outer tie rod is junk for sure - probably do a pitman arm and idler arm while it's apart.
But I found the issue - the sump was full of sludge and the pickup was fully submersed in it. Basically, once the sludge got warm enough to become viscous would clog the oil pump pick-up. tube.
I cut the oil filter open and I was surprised it's not packed full of glitter, so I'm gonna clean it up and put it back together.
-
All I have is, WOW!
-
Waiting on parts to show up.
I ordered inner/outer tie rod ends, pitman/idler arm, sway bar end links, and an oil pan gasket.
I'm almost tempted to do the control arm bushings and ball joints then the frontend would be fresh but that's a lot of work to put into this POS.
It'll probably need an alignment once I get the new tie rods on - I guess we will see how it drives once it's back together.
-
Other than the vaseline in the driver's valve cover it doesn't look terrible.
-
that is not an inviting???????????????
-
I should have saved some and mailed it to you!
-
Is that the result of water and grease?
-
It looks like it may have castech heads on them that crack and weep coolant. That explains the entire mess IMO.
-
Had to look that one. Marked down as what I learned today
-
Heads are off, lifters are out - and it's just a sloppy mess all around. Up next I'm gonna pull the cam and check it for wear. PCV system was functioning, the intake had a mess of goo in it and it was starting to remove the carbon from the chambers/pistons.

😵💫
-
Just chipping away at it. Parts will be here in the next couple of days
-
What are you doing about the leaky heads? A Cadillac pill in the radiator?
-
Leaky heads are in the scrap pile. I’m gonna use the set I picked up a couple weeks ago.
-
Back saver 9000 - so far it's been worth every penny.
-
My little experience with one suggests tht it might be worth more than gold, or catalytic converters!
-
That reminds me while it’s apart I need to get the numbers off the cars and see what they are worth. Might pay for headers/ypipe lol
-
LOL, I gave about three to some guy if he would haul off some other junk for me. Another dumb thing I could have made some money from but hate going to places and getting screwed on stuff I sell
-
I fired it up Sunday - let it run for 30 seconds. Instant 60+psi of oil pressure, and I couldn't believe how quiet it was with all the exhaust leaks fixed and a quiet valve train. It's way too cold to heat cycle it in the barn at the moment, so that'll wait until all the maintenance is done.
Yesterday I changed the ball joints, the idler arm, and the pitman arm. I've still got to install inner/outer tie rod ends, sway bar bushing/endlinks, and then service the transmission and differentials since I'm sure it hasn't been done ever.
-
About to be too nice to use in bad weather.

Just need to change the trans fluid/filter and check the toe. Like a dumbass I forgot to measure first so I guess I’ll see where it is and how well I can get it to drive. Might need to go for an alignment
-
set up some string across (and parallel to) the rear tires and across the front tires. Set the toe on the front within the two strings
-
Black Friday I was bored - so I cut the muffler off and put a Hooker Aerochamber on it. Now that it sounds good - it's time to tackle the leaking rear main seal.
About 5 hours in and it's torn down to the point that I can fix the rear main seal lol
-
and a short exhaust clip for fun - https://youtu.be/6HQpZwAizRQ
-
Sounds good to me. Six hours to go !
-
Probably be done this weekend - the transmission to transfer case gasket won't be here until Friday.
The transmission dipstick tube was stuck pretty good and the transmission was seized on the dowels. I dropped a few fbombs but it wasn't as bad as I thought it'd be.
-
Just got back from a test drive - other than reinstalling the transfer case solo, it was pretty easy. It's snowing so I even got to test 4wd
-
Now you have time to work on the next problem. :rofl: :rofl:
-
Tomorrow - new headlights and a muffler for the wife’s civic. Sunday an old friend would like me to help look at his wife’s car it has an exhaust leak.
