I’ve had really good luck lately with using rubber cement on plugs instead of lube and then giving the plug a quarter or half twist before yanking the handle back out. This wads the plug up tighter in the hole and the rubber cement hardens to further improve the seal.

Beautiful stuff, eating these videos up one by one, glad I found the channel. One Q tho - is it safe to wiggle the throttle body around like that? Was under the impression that moving the valve in any way is a big no-no as it can mess up the gears in the electronic motor so have been super careful every time. What's your take on it?

Great videos I love your stuff! Thank you. I am wondering when you put the Lollipops back onto the car is there a reason I shouldn't use Silicon spray to lube them up? I noticed you use glass cleaner. Oh and I also was wondering if when you used the term "Smack the Sh!t out of that thing" at 32:30 is a technical term?? I think it is as I've heard it used in many situations.
@DayOffDIY
Жыл бұрын
hey Greg! Silicone will stay on the control arm and potentially cause the arm to slip inside the bushing after installation. The glass cleaner provides enough lubrication to get the bushing on but evaporates and leaves no lubricating properties after the install. You want a dry bushing so the control arm doesn’t slip inside the bushing. Hope that helps

That stuff is a godsend on any rubber hose or o-ring that you need to slip fit. The only thing I don’t use it on is fuel injectors as I’ve been told silicone and fuel systems aren’t buddies. You can even use the spray to help remove stubborn coolant hoses like a penetrating oil.
Hey dude! Love your videos. I heard that this generation of chassis had a lot of issues with rear subframe bushings/ structural integrity. Would love to hear your thoughts because I’m looking to buy an old one to restore.
@DayOffDIY
Жыл бұрын
Hey cole! It’s true that the rear differential mounting locations age and fail, it shows itself by clunking in the rear end when shifting around gears, especially drive to reverse, but it’s repairable. The subframe mounts where the rear subframe bolts to the body can cause the body to crack sometimes, more common on the E46 M3. If I was buying a standard e46 I’d inspect the rear diff bushings but even if it’s shot out, it’s repairable. Eventually I’ll be doing a video on the repair, one of my cars needs it bad
