@Pᴀᴜʟsᴛᴇʀ2 Lycoming (who made the engine in the Piper that crashed) had previously issued a service bulletin saying that any use of fuel additives would void the warranty on the engine so even if they weren't using excess it was too much

@BobCross was the oscillation present before you did the work on the lines?

I remember reading some lines in the oem repair instructions of Opel/Vauxhall about fuel/oil additives: They void the warranty on the spot, oem supplied testing kits are supposed to be in the shop.

The only fuel additive I could think of using would be some kind of bacteria/algae treatment for the diesel tank.

@Martin yep.. GM and Vauxhall both

@motosubatsu yep. Exact same. I was thinking that maybe I had a vacuum leak.

@BobCross a reasonable assumption

and the BCS is absolutely the next logical diagnostic step

>The contents of Marvel Mystery Oil were 74 percent mineral oil, 25 percent stoddard solvent, and 1 percent lard.

That's neat: 1% lard

But "mystery oil" sounds better than "thinned paint thinner"..

@Martin whenever I hear the name it conjures up this image:

Yesterday, I tried to deflect a comment war here so that I could avoid a non productive argument about whether all summer tires are better in the rain than all winters. It’s so hard to get people to accept that the word “all” is a distinctly different metric than “some”....

@BobCross yeah.. it's the nirvana fallacy at work I think

Especially since my summers are kind of squirm worms in the rain

people just want a simple "yes" or "no" answer and refuse to accept that the world is more complex

I didn’t want to be mean. Reading Tire Rack articles and assessments is a good step. You can’t generalize too far though.

@BobCross you could always make their head explode by point out the existence of things like Toyo R888Rs

This tire is better than that tire in these conditions on that car.

@BobCross people always seem to forget the role the car plays as well

I've known tyres that were ace on one car be utterly dreadful on another

drivetrain layout, weight, weight distribution and geometry all play their part

Totally. I love my summers but they do have some power understeer problems in the rain. That’s a spooky feeling.

@BobCross yep.. had a set of Falkens on my WRX at one point that were plagued with that, even moderate power just pushed the nose wide

@motosubatsu That's a good one. Thank you for that

It’s hard to explain why power understeer is spooky to normal people until they’ve experienced drop throttle oversteer. Things go from worse to WORST! quickly

@BobCross lift off oversteer.. the cause of many a bewildered person standing beside their crashed car repeating "but I was trying to slow down!" and "there must have been diesel/black ice/banana peels on the road"

“How did I end up going backwards?!”

It’s happened to me. It’s the craziest feeling in the world.

That was before I was a Dad. Got rid of that car quickly and decided that I needed to be better at cars and driving in general!

and old commuter hack of mine (Pug 306 diesel) had a terrible tendency towards it

@BobCross that's the sign of a true driving enthusiast IMO - someone who makes an error and says "how can I be better rather than just blaming something else

@BobCross I was not intending to start a comment war. I think we can agree that some summer tires are bad in the rain and some are good in the rain. We can disagree on the amount. But both of us used words that implied a broader assertion.

@3Dave - I remember that story.

@mao47 if you look at the sipes in a winter tire tread block, you can see trade offs in action. The sipes give water a place to go, increasing traction in the wet. However, that breaks up the tread block, making things squirmy.

@BobCross Yes, but at least with my current tires, I'd still prefer the summers as long as it is at least 45-50 degrees F. I agree my comments were too general. But I think your parenthetical in the original answer was also too general.

@motosubatsu All small Peugeots of that era were terrible for lift-off oversteer - it was the light rear-end with torsion-beam suspension...

My 306 Diesel was probably the worst car I've ever owned. Hateful thing

@NickC yep.. add in the heavy diesel lump up front and it was a nightmare

@NickC seconded! god how I loathed that car

uncomfortable, leaky, dodgy handling and slower than a tranquilized snail

@motosubatsu It put me off Diesels for ages - then I bought a Diesel Toyota Avensis back in the summer, and it's a totally different beast - I think the technology has changed so much in the intervening decade...

I only paid a hundred quid for mine - still felt like I'd been hoodwinked

@NickC yeah it's come on leaps and bounds since then, was yours Turbo or N/A?

Turbo - the 1.9

which meant it wasn't slow - but it was noisy, uncomfortable and terrible handling!

cost a lot more than £100 too - about 8 or 9 iirc

@BobCross Also important to consider is hydroplaning resistance versus raw grip on wet pavement. Summers will probably always, or at least often, be more likely to hydroplane. As long as you stay under that threshold, you may be able to get better grip. I have Dunlop Direza ZIIs and I've only hydroplaned when I was actually just going too fast for conditions in general.

@NickC luxury! mine was the hateful N/A variety - it didn't really drive places, it just waited for continental drift to get you in the vague vicinity of where you wanted to be

@motosubatsu I can imagine - a friend at the time had a n/a 106 diesel, that was seriously slow

it was also had a really odd spec - electric sunroof but manual windows

@motosubatsu safer that way - when the electrics fail you can still open the windows!

and being a 90's Pug, the electrics would, inevitably, fail

@NickC true.. and the electrics certainly had something of a flighty temperament

the headlight brightness would vary noticeably depending on whether you were pressing the accelerator or not

the exhaust and the engine parted company once.. which was fun as I happened to be doing 70(ish) on the M55 at the time

@motosubatsu oops!

@NickC it sounded like someone had brought a tractor to life for the sole purpose of torturing it extensively, and somehow it got even less powerful

@motosubatsu - Sounds exciting! How can I go about that? ;-)

@motosubatsu Have you never seen tractor pulling?

hehe

@mao47 yes and also just grip under power can be a problem for summers in the wet. That’s when I was seeing my front end wash out in our rainy fall, just driving at highway speeds around a corner.

@BobCross sounds like FWD problems ;-)

Actually WRX is AWD

Weight transfer away from the front end under acceleration is an always thing

@Martin - Hello, kind fellow!

@Pᴀᴜʟsᴛᴇʀ2 Hello, I hope everything is fine?

@Martin - Yes. Playing hookey from work today. Had to help my daughter's friend change a tire last night. Was up until almost midnight. I didn't think I'd be too useful at work on about 4-4.5 hours sleep, so stayed home.

@Pᴀᴜʟsᴛᴇʀ2 I just recovered from the flu. At one point we all, the entire 5, were lying peacefully in our bed side by side without making any noise. Seemed so unnatural :)

@Martin - Because you were not feeling well enough to move?

@Pᴀᴜʟsᴛᴇʀ2 Yes, we all had the whole package

@Martin - Oooooo, that'd be ugly

Hopefully, though, since everyone had it at the same time, you won't be passing it around again.

And also because it is so unexpected from the kids to not run around, scream and do kidly things

That has to be the worst ... one gets it, then the next, and around the horn to when it starts all over again.

It was intense, but short. Everyone is fine now.

I think about getting a flu shot next time..

I'm very glad to hear everyone is doing better.

Ty

When you say "short" ... how short was it?

And did it come on like gangbusters?

The reason I ask, "short" when you think of the flu, to me says "Norovirus" ... which is nasty but very short lived.

I got it on Friday, at Saturday was the peak and Sunday was the last time we had fever

Sounds a lot like Norovirus.

Not that I'm a doctor or anything, though, lol.

Who really cares ... done and over with for this go around. It's the end which is what means anything.

we had no gastrointestinal issues, so no Norovirus

in other news: I bought a biscuit joiner

@Martin there's an upside! norovirus can be a PITA as it will re-infect

@Martin - Nice! I've had a biscuit joiner for several years. I think the package is still sealed, lol.

Best laid plans of mice and men ...

@Pᴀᴜʟsᴛᴇʀ2 I want to make some under-bed toy boxes for the kids, lets see when I will have time for that

@Martin - Isn't that always the case?

Time seems to never be on our side.

@motosubatsu That would have been an nightmare

In other news, I got the rings in for the SBC 350 I'm rebuilding. Maybe I can get the pistons in the engine today. I still need to get a lot of parts for it, but it would be nice to have the shortblock ready.

@Pᴀᴜʟsᴛᴇʀ2 Aye, we just had our project planning meeting: i wonder where they got the idea that all this is doable

@Martin - Management: Can't work with them ... can't work without them.

@Pᴀᴜʟsᴛᴇʀ2 Seeing a project become completed is a marvelous thing.

@Martin - Absolutely

@Martin - That is pretty kewl!

one bolt costs about 5€

@Martin ouch!

Oh, I'm sure it isn't cheap! lol

the entire starter set goes for 450€

@Martin - Starter to me implies everything you need to get started, but you'll be buying a whole lot more to get finished!

Hooray for magnets!

@Pᴀᴜʟsᴛᴇʀ2 you get a package of 20 bolts in the set, you need to buy the rest you use..

@Martin - No doubt

@Pᴀᴜʟsᴛᴇʀ2 Check this out

Oops - wrong one. The second graph is for 4th gear (1:1 gear ratio).

356 whp / 378 lb ft.

It's all calculated based on a few HP tuners runs, but everything I've read indicates that it should be within a few percent of the real thing.

noice

Given how squirrely it gets when you put your foot down, I don't have any issue believing those numbers are pretty close.

Not too bad for a little 2.0L.

That’s an interesting dip at 4800

OMG my local Subaru parts supplier makes me crazy. Sure, I think, but local and support the economy. Pick the part on the website, enter all the billing data and the pick up onsite option to avoid shipping. Click PURCHASE and... nothing. Website doesn’t recognize the click. Click click click! Nothing. ... checks Amazon and sees the same part that would be covered by Amazon bucks. Purchased!

And before I get the requisite “but why didn’t you call them? You millennials!” I was already on the phone talking to my real life work job people. Can’t make two calls at once! 🙄

@BobCross - What, you don't talk out both sides of your head? What's wrong with you??

I’m already talking and typing about two different things. Do you really think it would be a good idea to add another mental task to that mess? I don’t and I have to live in this head!
