Playing with my new to me engine hoist, looks like the jack piston (handle side) is leaking quite a bit.
Noticed after draining some old fluid, topping it off and bleeding out the air.
I have some fluid with "stop leak" in there, left it over night in a position where it's not pouring out.
If it's still leaking I'll try some new random o rings to see if i can atleast slow it down.
I want to replace the ram with one of those pneumatic assisted units anyways, but i would prefer to do it later... lol

Can it be taken apart? Or is it one of those sealed units--the jack piston.

It can be totally taken apart.
And i did find a seal kit for about $25 if i want to do the whole thing.
Found some videos on youtube talking about it.
However, a jack only costs $50
A pneumatic version less than $100...

I also did pull the jack piston out last night, bleed out a bunch dark fluid. Lol
I saw a long looking o ring seal on there.
I bet i can support it with a single o ring or try a stack of em.

Lol. I’m thinking hers might be able to trim some. It’s her foreleg so doesn’t take 24” for the cone of shame to work.

Those jack pistons let go at the worst time..............

Durn! I’ve had her just over a year, but with all the shit that happened in my life last year, she’s like a therapy dog.

Me too!
For me, all dogs are therapy dogs.
With probably the best dog we ever had, I spent a lot of time on the road with her trying to save her. She loved to travel in the Yukon.
Our country vet gave her 6 months from when he first diagnosed her cancer. 16 trips back and forth to UC Davis Vet hospital for surgeries, chemo, radiation, etc., we lost her exactly 6 months after she was first diagnosed. Sometimes nothing works.

Not sure if this has been discussed here before, but apparently after you hit 10,000 gallons of gas used your car stops counting.

Same here, 264,*** mi.
I'm not sure if it can be reset or not, never tried... maybe with the DIC, maybe with the Tech2... dunno... guess I don't really care either... lol
pretty sure you just long press the checkmark while on that screen and it resets, but I could be wrong

You know what that is? That’s fu**in ********, that’s what that is.
Yeah it makes you feel taken advantage of for sure.
I am just hoping that maybe one of the others was defective and these don't turn out to be garbage also.
Unfortunately I won't really know until we get some "cold" weather again... which isn't looking very promising at the moment.
The next coldest night in the forecast is only supposed to get down to 47°.

Both of mine show that.

Well, i removed the jack from the engine hoist, laid it on the side, pulled the jack piston out of there and stacked in some O rings.
on the tip there is a wiper looking seal that looked good overall, but I'm sure it's just old.
So i stacked a little o ring on the far end, pushing the seal towards the tip.
Seemed to expand it a bit as there is a ledge to keep it on there...
A wee bit up the shaft has a second seal, I assume that one is to keep fluid from escaping.
It was pretty freakin flat.
I added a o ring on the end of that, seems to be successfully pushing down on the seal and making it a little thicker.
I had to grease it up pretty good to reinsert, but so far no more leaks.
And jacking it up seems to be much more solid now!
I'm still deciding if i want to trust it or not...

Well FML.
Let me tell you doing valve springs in the truck is not fun........make sure you have the right tool. The tool I was using worked great for the first 6 valve spring on bank 1 and 2 is fine........but cylinders 7 and 8......no chance in hell.
I ordered the other toll via Amazon and will be able to finish tomorrow.
Oh, and the tool I used only worked after I milled it so there was proper clearance to install the valve spring retainer keepers. I'll port up some pics in a bit.
Either way, experience, a level head and knowing when to tap out is the key to success. Plus having the valve spring pop out of the tool twice was enough for me to call it a day. Safety first.

Am i the only one that actually uses those to keep track of how much fuel i might have left when it hits "E"
Kind of disappointing. I was thinking you can reset it (like a trip odometer), because when I first got my truck, I think I reset it, then realized I wanted a long term running count and thought I would never really know exactly how much I had used.
I am getting up there, might be time to write down where I am at with total fuel used and see if I can reset it.
I like to be able to quote how many gallons I have used in total when I am around my more greenish friends.

yes, it can be reset. yes, it can be useful when on a trip or something where you want to keep track of how much fuel you've used.
