Is there any good way yet to retrofit the headlights on a ten-year-old car to LEDs? Ideally, I'd be looking for some kind of drop-in unit to replace the bulb.

No.

The bulbs are not enough. The projectors matter so you don't blind people.

There is also no DOT approved way to do this that costs less than buying a car that has LED lights or at least LED lights as an option and retrofitting the correct OEM parts to your car.

Reposting this from the last thread, I am wondering if I'm destroying my wife's car.

No. I don't know where he got that idea.

Spinning the tires won't do anything at all to destroy the diff. Heavily loading them repeatedly to spin them will obviously cause issues (like on dry pavement), but that has little to to with FWD/open diff/LSD. But the most likely place to break parts when spinning tires - which again has nothing to do with FWD/open diff/etc - is when they're spinning and you suddenly regain traction, like going from mud to dry tarmac or spinning on a patch of ice and then hitting dry hitting tarmac.

Yes it is, that's (partly) what a vacuum gauge is for. Normal being around 17-22 inches of mercury, my car is around 25. I don't know how to answer your question beyond it being a vacuum gauge explicitly designed for this purpose. I was actually hoping to discover incorrect ignition timing or something like that.

I think he was getting at the fact that you used "normal" as a measure. None of that matters diagnostically. What matters are real number and how it's moving in which conditions.

It's not complicated, but it's not something like "between x and y is fine."

Here's the best thing I could come up with. Feel free to ignore the article, I sure did. What matters is on the bottom. Click the scenario buttons until you find what yours is doing.

Which article...?

Also, every diagnostic vaccum gauge I've seen has a green zone around the numbers I stated that's 'normal'. Vacuum readings don't vary much from engine size/configuration as long as there's no forced induction involved; an engine in good condition and a good state of tune will always pull around 18-22 inches. My engine pulls more than that which makes no sense. The needle doesn't fluctuate or flutter or anything, it just sits steady with a shaking that matches the idle shake.

Sorry, forgot to link it:
http://www.secondchancegarage.com/public/186.cfm

As to the rest.....yes, most vacuum gauges have that. It doesn't mean it's all that matters or even how to most effectively use a vacuum gauge. To diagnose what you are now describing it would be best to do things like snapping the throttle to see what the readings look like, running at higher RPMs, etc.

Vacuum rises with RPM when the throttle plate is closed like under deceleration. Under some conditions/configurations I could see this happening with a high idle or wonky valve timing/incorrect preload or advanced ignition timing. Just what is this thing idling at without load?

So is the 'synthetic is bad for high mileage vehicles' adage just an old wives' tale, or should I really avoid it?

I'm considering switching to synthetic in my old (2000) 4Runner. I have a small oil leak at the camshaft plug at the rear of the valve covers. My plan was to redo them, making sure it was done appropriately, degrease the engine, check for any remaining oil leaks, then make the switch to Mobil 1 or something similar.

My father, who worked as an auto mechanic for years in the 70s (and is extraordinarily competent) says its a bad idea because it can cause new oil leaks. Lots of online information says this isn't necessarily true and synthetics will extend the life of the vehicle.

There's logic on both sides. What is the conventional wisdom on AI?

Yes, it can cause more (not new) oil leaks. So can any quality non-synthetic oil. It just so happens that most if not all synthetic is high quality and therefore has a good detergent package.

So if the method of oil sealing on your motor is primarily "nasty old oil sludge" rather than "undamaged gaskets", sure.....it can cause more leaking. But that means it needed to be repaired anyway.

Been having A/C issues on the Protege, it acts like it's freezing up. Hooked gauges up; static pressure is fine, while running it reaches good pressure, but then the compressor keeps drawing up the pressure difference; I saw readings in the vacuum range on the low side. Do I have a hosed pressure switch that just lets the compressor run full time, or what?

I did throw a can of refrigerant in just in case; no change, and it actually started cycling when the high side pressure spiked to like 400 psi. This was last night and nothing is any better today, and I suppose it'll be venting itself back down to more sane pressures later tonight.

Don't pull fuses you think could be associated with the problem. Pull every single fuse in the car. There will be another fusebox in the cabin somewhere that deals with interior stuff (usually behind a kick panel) and I'll bet at least one fuse in there is blown.

All of the stuff you've listed as not working is controlled by a body control module and you've probably blown the fuse(s) protecting this. Hopefully.

You mean like the fuse he attached the jump box to that he doesn't know is a fuse?

Testing it's performance under load, basically, but the parts stores do that. If they said it's good, it's probably good.

Unless they used one of the quick testers that often get faked out by marginal batteries with surface charges on them.

If the test didn't take at least 20 minutes it wasn't tested on the real rig (the carbon pile load tester). And if it WAS tested on that rig the end of the test is to recharge the battery.

I figure I can just dremel the end of the screw, make sure that the tip on it is smaller in every way than the smallest dimension of the thread it needs to be backed out through, back it out, and then tap and die it to make sure they're both ok. Anyone see any major issues I'm missing that might gently caress me?

That's how I'd do it. Run it in all the way, cut it off, then use a grinder bit to bevel the edges before you unscrew it. Bonus point for chasing the threads, but if you bevel and clean up before removing it shouldn't be necessary.

How would using a floor jack on the pinch welds be any different from using a scissor jack? Its still exerting the same amount of the weight of the car on that small area in either case.

Scissor jacks have a cutout for the pinch weld.

You can get pucks to put on top of a regular floor jack to accomplish the same thing. Without something like that you're just going to fold over the pinch weld.

Tires! I'm not sure if this is the place to ask but I didn't see a tire megathread so here we go.

If it matters I'm driving an '02 Silverado 1500 and right now it has Toyo M-55s on it (to quote the sidewall: LT 235/85r16 M-55 M+S) that are getting near being slicks. So it's new tire time.

I work construction, which means I get a lot of highway miles commuting to and from work, as well as miles on big projects with roads that range from 'grubbed dirt track' to 'we bladed in a load of 6inch minus, good luck!" or even fresh shot rock with sharp as gently caress edges, so tough tires are certainly a requirement. As well as the typical jaunts up logging roads to go shooting in random borrow pits.

Please recommend me a tire, I really don't know what I should be getting. I do understand that good tires (like the ones I have that have lasted me a long time) may cost some money, that's fine. I'm not expecting some $75/ea shitpiles to fit my needs.

BFG Commercial Tractions are on the more expensive side but are loving great for things like this.

You can often find them as take offs for a more reasonable price (they come on a lot of 3/4 and 1 ton trucks and vans from the factory).

Is corrosion on the battery leades a sign of a problem?

Yeah. At a minimum it means your connection is going to poo poo and the terminals and cables are being eaten.

Neutralize the acid with some battery terminal cleaner or baking soda/water, remove them, clean them, neutralize again and reconnect them. Make sure they are tight and use dielectric grease to keep it from coming back as soon.

If it comes back quickly it can be an indication of poor connections, overcharging or a spanked battery. If it's not a sealed battery check that it's full and top it up as necessary. It also happens faster if the plating has been eaten off the terminals.

Beware long post.........

You drove around with a bad battery, causing your alternator to run at 100% trying to make up for it. You trashed your alternator (more specifically the voltage regulator) because of this.

The alternator light being on doesn't necessarily mean it's not charging at all, just that it's not charging sufficiently.

Change your alternator and don't drive around with bad batteries. Or bad alternators. Either one will destroy the other.

I know its the choke symbol but I've got no clue what its function is on my van since to my knowledge it doesn't have any choke you could operate. The owner's manual says nothing about it. Any ideas what purpose it would serve?

That means the idle enrichment valve is operating. Yeah, choke if it's got a carb (electronic) but on some early FI motors they used the same symbol.

It should go out once the engine starts to warm up. If not, there's a problem (and you're probably running super rich).

Anyone got any good ideas on how to find a fuel leak other than getting under the car and looking for dripping or wet spots? There's nothing obvious, but I can definitely smell it and mpg is starting to suffer. It's a '96 4cyl Camry, any ideas?

It's probably on the top of the tank (fuel will pool in the indentation where the pump and sensor goes) if you smell it for a while. You'll get it there when you fill or when it's mostly full and sloshes around.

I don't think there's going to be any easy way to check - you should pretty much run that thing down to E and drop the tank.

If it's just after you fill see how much of the filler neck you can get too.

And that's if it's in the back. Up front should be easier. Normal suspects are fuel hose to FPR and rail connections and around the injectors.
