Finally - god that pig is dirty now from being on the road for the past 10 days.View attachment 386233View attachment 386234View attachment 386235

@Charlie207 Look at the lugs in the pics - that is 2 years on the truck and they look horrible...Hope yours turn out better than those!

Mine are getting a little rusty. I may repaint them in the spring.

What is that red car in the garage?

Nice crib! Like the woods.

I have a little over an acre with about half wooded with a creek running through - beats the hell out of the "peoplely" living back in Florida!

'91 Mustang 5.0 convertible - just an expensive toy that gets about 1000 miles a year put on it.

So, while in Florida last week, visited my friend with the lift to address my o-ring pickup tube issues and the correct oil leaks that were happening. Put the 'hoe on the rack, pulled the pan and found a leaking cooler line gasket and pan gasket. While in there with the pan off, replaced the O-ring that was REAL flat (getting about 18lb pressure at idle) thus getting low pressure. I even got a CEL on the way to Florida. So much for Fleet maintenance, lots of gunk in the bottom of the pan, and fresh oil now with a PF63 filter. On my truck, the filter does not sit below the bottom of the pan and I am happy to report that I have about 22lbs at idle and run about 28 cruising at 70mph once full warmed up. I have to thank the folks on this forum with the knowledge and info about what to look for and fix for the leaks and pressure issues.

How many engine hours do you have?

 

[Fubar0715]

Oh, an ass load of them! LOL

When I replaced the O-ring, nearly 9500 hours, which I attributed to the failing pickup tube.

Gotcha. Thecopcar has about 20 psi at idle and just under 40 cruising when warmed up. It has 9700 hours.

I was barely getting 20ish at speed...If I happened to get on the loud pedal, it would creep up to nearly 25lbs. Today, I am seeing 40ish when getting fed extra dino juice! The time spent fixing the pickup tube issue gives me piece of mind that I might not kill the motor!

Well that makes me feel better I guess

Indeed, I’ve only got 207,000 on the clock.

My hours were reset after I got an alignment years ago. IDK how they did it but I think they ran the battery dead and something weird happened when they were boosting it off.

That is a LOT of miles - Wow!!! Thought my old Tahoe had a bunch at 260k - I want to be you when I grow up! lol

 

[avalonandl]

I hope every one had a great Thanksgiving ! I have been away awhile.

Have a shock replacement question: 2007 GMC Yukon SLE 5.3 Flex fuel

I need to replace the original ( 77K miles ) rear shocks. The OEM ones are pictured as are the heavy duty ones.
I never tow anything, but will be towing a 20 foot cargo trailer next summer from Seattle to Ohio and am thinking maybe I want heavy duty shocks vs OEM standard

Everyone's thoughts ? thank you in advanceView attachment 386163View attachment 386163

I would only buy Bilstein shocks, ride much better than OE.

 

[RooTBeeRthe1st]

Been driving her real nice this week. Average mpg has come up a half gallon. Lol can't remember exactly when I reset the gallons used, but it was 2-3 years ago I think.
Almost forgot to check my odometer. Always add a quart of oil 2500 after my oil change.
Checked it when I got to work, sure enough exactly a quart low. Dumped in the court I always have ready to go in the back.
Haven't checked my hours in a while but mine's just a wee baby compared to what you guys have. Lol

I just ran the math on that and it would require an average speed of 69.1 mph to cover 344K in 4982 hours. My guess is your hour meter was reset at some point - perhaps when a new engine was installed by a previous owner? Or perhaps accidentally as others have seen? Either way, that's impressive mileage on any vehicle and shows us just how durable these trucks really are. Best vehicles on the road, in my opinion.

Was living it's best life as a test mule on some proving grounds until @RooTBeeRthe1st took possession? Unlikely but you can dream!

I know the dash cluster was replaced, could that do it? This is the original engine for sure, 2nd trans and rear.

I have seen that Hours Meter reset itself before without any prompting from a user and just does it on it's own. It's not uncommon.


OOOORRRRR....Biff drives like an a$$h0le all around PA whilst flipping the bird and yelling profanities.
