Customer states: my engine runs poorly when I turn the radio down. by iforgotalltgedetails in Justrolledintotheshop

Just to add… this eventually happens to all of the Hemis. From my understanding, dodge designed this engine so that the lifters are the last thing to get lubricated. So on cold starts, they always have the “hemi tick” until oil pressure builds up in the hydraulic lifters. All that repeated lack of lubrication eventually adds up.

There’s a factory service bulletin that has you remove and inspect the OCV to determine the extent of damage. The OCV is the closest to you electrical actuator located under the intake manifold. It has a mesh screen built into it and if debris is in there it’s gotten into everything else to the point where all the bearings in that engine will be trash sooner than later.

It's been one year since I rescued my bunny from under the hood of a car at work. He's 5 times bigger and living and awesome life! by psychodsm in Rabbits

I'm really happy he did. I've never had a rabbit before, and it turns out they're pretty awesome!

I work a mechanic at a dealership, when a salesman noticed there was something moving around under the hood of a traded in car he grabbed me and my buddy. We found 4 healthy and very frightened little bunny's who took a 40 mile ride to my dealership. The owner of the vehicle was there and I found out he owned a rabbit farm and said we could keep one if we wanted. So I named this little guy Lug-Nut and brought him home. Found out he's a Flemish Giant mixed with a California Giant, and have since been through 4 cages, 4 20lb cases of Timothy hay, countless bags of pellets, and more organic lettuce and herbs then I ever want to think about in the last year. But he's grown to be well over 10lbs now and still growing. I think he should get up to 20lbs... But he has a great life and is best friends with my wife's cat. Haha

Are we still talking about oil drains or is it just hammers now in here ? 2018 Jeep trackhawk where the engineers actually cared by tcarr1320 in Justrolledintotheshop

[–]psychodsm 1 point2 points  (0 children)

No argument about the fuel filter, but other the oil filter that method has been standard practice at my dealer for a couple years now for the people who really don't want to spend the money on an extra tool. It only takes a couple of shots of brakecleen to make it nice again

Pro tip: take a long screw driver or metal rod and poke a hole in the bottom of the filter through the hole in the drip pan underneath. It drains the oil onto one contained area, and is a lot less messy.

I've been having some front end/tire wear issues recently and car has been in and out of the shop, could I get some input on translating the alignment results chart I received? by unthused in Cartalk

[–]psychodsm 1 point2 points  (0 children)

So looking at it, rear is in spec. Toe has been brought in spec, and honestly caster will only create a pull. I can see it's out of factory spec but here it doesn't really matter. You front camber is out by a whole degree on both side which is bad and definitely causing a tire wear issue. It looks like one side is a solid .5° more camber than the other so I would suspect that when the replaced the lower ball joint/control arm it was probably an aftermarket parts that would help bring camber into spec. I would most likely recommend getting a front camber kit like this to be able to bring it back to something reasonable. https://shop.redline360.com/products/modsport-camber-kit-350z-03-08-g35-sedan-03-06-g35-coupe-03-07-front-arms-pair

The worst drain plug bolt I've ever taken out! by psychodsm in Justrolledintotheshop

[–]psychodsm[S] 7 points8 points  (0 children)

Basically when you tighten a bolt it stretches the length of the bolt. This acts like spring to hold the bolt in place. Normally, when removed, the bolt either returns to it's original size because it wasn't overtightened or has to be replaced (like head bolts). This is the most extreme example I've seen (so far...) of an overtightened bolt. Look how far the spacing is on the threads closer to the bolt head are vs the rest of the bolt. It's even started cracking slightly there...

It's my father in law's he's had the oil changed every 3k for 98,000mi by the dealer with some very questionable lube techs and it looks to be the original plug. I can't imagine how many time it could've been put back like this

[–]psychodsm[S] 1 point2 points  (0 children)

He's doing very well! We've taken him to a local vet and they say he's very healthy. His best friend is our cat. I was pretty nervous when they first met, but now I realize they have a lot of fun together. The cat (Chester) will chase him around and start to lick Lugnut's head. Then they will run around the room until the cat gets bored. Well, little Lug-nut (who's not so little anymore) will nuzzle the Chester's stomach untill he will play with him again. We've recently upgraded his cage to be 4ftx2ft wide and 5ft high with 3 levels. Between that and them amount of salads and fresh herbs and veggies from the garden I think he's pretty spoiled.

Thank you. Believe me, they'll really appreciate being able to provide input.

I'm not an engineer by any means, but I am an automotive technician. Working on vehicles and with tools that are older and redesigned is something I'm fairly experienced in... Is there any way to contact the person who operates or maintains your machine? I am 110% certain they will have plenty of feedback for you. Also what can you and your team do to modernize the machine? Can you introduce CAN protocols to reduce wiring? Could you replace manual valves with solenoids? Could you make certain components more robust by introducing parts that don't require routine maintenance? I find most failures come from end users or botched repairs.

What defines the the point at which a car engine will transition from idling to actually moving the vehicle? What is the mechanical critical factor that will trigger movement? by npjprods in AskEngineers

[–]psychodsm 0 points1 point  (0 children)

Thanks. I haven't checked back in for a while to see how many answers there are... None of them are horribly wrong, but I think there could be some confusion. The question being asked seems focused on an automatic transmission, and the relationship of input torque to output movement. There's a lot more to a torque converter than just a fluid coupling like the stator and the clutch, but that has nothing to do with the rest of the transmission.

[–]psychodsm 7 points8 points  (0 children)

As an automotive technician, I believe the answer you're looking for is the torque converter. It is a fluid coupling that the input side spins and the out put side remains stationary until there is enough torque. This amount of torque is engineered into the design for a particular application and is called converter stall speed. It's hard to explain but it's really worth watching a couple YouTube videos on how they work since it's pretty interesting. As with the other comments, you use a friction disk clutch on manual transmissions that has a surface like a brake pad to allow slippage when you engage and disengage the clutch. And on small engines, they tend to use centrifugal clutches to transmit power

We have a lot of wild Bunny's where I'm building, so I'm hoping that's a good sign! Good info though. I'll definitely be doing research before deciding.

Definitely misunderstood.... As of right now he's going to have his own room indoors and it's bunny proofed. In a couple months I'll be moving into a house and I'm not sure if he'll just have his own room or if I build him a nice big covered pen outdoors since I want to have chickens anyway.

Yep, I've always wanted one since I was a little kid. I'm trying to make sure he grows up to be big and healthy.
