Fix it Sunday... Master Mechanic, ask me anything!

Good morning...I'm still waiting on OP.

Good morning. How many miles on this car?

The 2010-2012 Panamera, Panamera S, Panamera 4S and Panamera Turbo have a recall regarding camshaft controllers (phasers) coming loose. This will cause the engine to stall. See NHSTSA campaign number 17V368000.

P0021 references camshaft position A timing over advance Bank 2. Looking at cylinder configuration for Porsche Bank 1 is on the right side. Cylinder numbering is like Ford with cylinders numbered front to back, 1234 on the right bank and 5678 on the left bank.

You may have broken adjuster bolts.

I'm trying to change the blade on my Circular Saw .

I have the right allen key , have used lube.

And locked the blade , but I can't get it to budge.

Suggestions?

Use a deep well socket and extension, or pliars to get more leverage on the Allen, and remember they are reverse thread!

Righty loosy lefty tightly. Basically to loosen the bolt in the opposite direction of the saw's rotation.

What if I were to dump / siphon all the liquid out, and flush it with water? Then store it dry?

Seriously though, what about keeping said battery on a trickle charger?

And further, is the continual cycle of discharging / recharging what eventually kills a battery?

Proper storage and charging can offset it a little bit but lead acid batteries just don't store well due to sulfation.

Turns out Porsche thought it was a good idea to use aluminum bolts on the camshaft phasers.

:tired:

Op I don't know what that means...

Aluminum is a very weak metal for a bolt. They tend to be used as safety fuses to protect components in the event of a failure. The augur on a snow blower has an aluminum bolt that's designed to shear if it eats a rock so the gearbox doesn't get damaged.

However in this case they are loosening up and breaking.

Call your Porsche Dealer and see if your car is covered under the campaign. They'll pay to fix it or they will fix it free.

I know what that means.



They don't make them like they used to, they are no longer built to last.

OP never told me what the green blinking arrow is :(

The filter was pretty bad but didn't solve my problem. Mower runs "better" but still runs only on choke, although more smoothly now, and dies when blade is engaged. I guess I'll try cleaning the carb tomorrow. The valve on the float was sticking a while back because the bowl had dried out. Was hoping sea foam would help clean it out and lubricate.

Search you tube for carb repair and the model mower you have.

You no doubt have a clogged fuel port inside the thing.

This guy has a bunch of videos

Did you check the filter again after the initial cleaning? I had to blow mine out 3 or 4 times before all of the gel was out of my tank and lines.

Cleaning the carb is always a good idea though anyways and replacements are cheap on ebay.

Good luck.

Dude you have no clue what you do go to a uto part store buy. Rebuilt engine all you need are covers

I use fuel inj cleaner on my Tacoma but instead of full tank wait till it neAr empty super concentrated seem to give better performance agree?

Face it if you had .micrometer you would not know what to do withit

Sounds good in theory but that stuff in a concentrated form might cause damage to internal seals and other softer materials in the fuel system.

I wouldn't do it. If you really want to clean you injectors a good shop will have a machine to run cleaner through them under higher pressure than what your normal fuel system has.

I would go that route even though it will cost more, maybe a lot less expensive in the long run.

I had that problem with a Honda 2200i generator. Turns out it was a clogged fuel filter. Problem is the fuel filter is inside the fuel line, disguised as a hose union. To get at it the whole front indicator panel with receptacles needs to come off from the main part of the generator, not disconnected though.

The first time it happened to me, I naturally took it to the local authorized service center, and it came back the same way and $60 later. Turns out they didn't know about the fuel filter either.

I was just going to mention Steves Small Engine Saloon.

His video on Stihl's chainsaw gas has very informative. Gasoline from the filling station should be renamed, benzene.
I was so impressed that I bought a lot of it, mainly because I like the cans. Only mixed gas goes into my chainsaw gas cans. When I run my saw, you can definitely notice the smell of paraffin wax.

VW Amarok, low fuel pressure, limp mode. Is it the pump? Thanks in adv.

Op...This is a mean world brother. I towed it to a shop by referral and the 'bros' are trying to tell me that it is a high pressure fuel pump gone bad. Cost $5000 and I told them that I replaced that part last year. Then they told me just come get the car off their property...smh

Good luck with your repairs.

My Honda Civic will not climb a hill with the air conditioning on. It runs rough and looses power with the air conditioner on. Any tips?
thank you

PS I do not drive very often and thought to myself when I had this problem a few days ago; I will just ask the auto tech guy next time he comes online. LOL

I had an old CRX hf that struggled with the AC on. People don't realize how much power they consume until they use it in a small car.

What year is your car? Has it ever had a tune up an the air and fuel filters changed?

2000, not in the last ten years, But I only drive it about 6 times a year to the nearest town. Thanks for the tips.
