Here's a dumb question... how much gas smell is normal from used motor oil? I asked the lube tech to capture some oil for me at my last change so I can send it off to blackstone for an analysis. I noticed it smelled like gas... a medium level of gas, not super strong, not just a hint if that makes sense. 2013 Taurus SHO with 74K miles on the car. It's a Gen 1 3.5L EcoBoost engine, so the main reason I'm getting the oil tested is to get a baseline reading of the oil right now, and keep an eye out for any coolant in the oil which would be a sign of failing water pump seals (which are a huge issue on that engine). Engine pulls strong, no coolant usage as of right now, no smoke from the tail pipes, so I want to assume everything internally on the engine is still working properly. The ~internet~ say some gas smell is normal in used engine oil but how much is normal? Edit: fwiw I dont drive much anymore. Mostly short trips, and the oil had only about 1000 miles on it and was 9 months old if that matters. skipdogg fucked around with this message at 22:03 on Mar 6, 2021 |

Motronic posted:Why would you want higher RPMs for a generator? They're also not very fuel efficient. Oh I was just watching a video where they said your backup generator should be rated to run at 50% load for best fuel efficiency / lifetime. Just made me think about the different characteristics of a rotary. luminalflux posted:LiquidPiston is a CT based company working in a DARPA contract for this. Their design is a bit different than a normal wankel in that the combustion chamber rotates. Looks kinda promising Wow, that looks neat, if feasible. Right, everybody talks about how a rotary would be a great range extender for an EV, if you can keep it in its ideal RPM range. For a generator I'd guess you'd want it with a pretty static load range then. Mazda is supposed to bring one out soon, let's see if it lives up to the hype.

Just made me think about the different characteristics of a rotary. So you're talking traditional generators, which need a specific RPM to match frequency. 50% load is the same RPM as 100% load as is 0% load. Where it might be more interesting would be on an inverter generator if the torque curve was right.

I remember fuel dilution being a concern with some DI engines, it was with my 08 MS3.

Short trips with direct injection is a great way to end up with a decent bit of fuel in the oil. If you're sending it off to Blackstone they'll tell you exactly how much. But if it's that plainly noticeable to a sniff test, you probably just need to take an occasional long drive.

Ah, I see, I was watching as I was falling asleep. He was talking about a whole house generator I believe, so that makes sense. I've only used the inverter kind which for our use load varies a lot depending on if it's powering a pump, TV, microwave, etc. It was just a curiosity question though.

The new hotness is inverter, and the ones big enough to do a whole house at that size are spicy-priced still, but yeah would be awesome. They are much more efficient. And quiet unless you're running full tilt.

The cold start enrichment on the first generation ecoBoosts is absolutely insane. Fuel dilution in the winter is a thing and a problem across the board. Not just for Ford.

I live in a sketchy neighbourhood and apparently recently there's been a number of people with Honda Elements getting their catalytic converters stolen. Shows that there are thieves willing to steal parts from cars. This morning noticed that the latches on my Jeep YJ hood were left open. Drove the car today. Seemed fine. What do you think they could have been looking to steal from a Jeep? Anything I should double check? edit: clarifying that it was the hood that was opened.

Doesn't even have to be that sketchy tbh - cutting a cat out of a car is fast and quiet depending on the tools you use. Prius cat theft is really common in SF.

I live in a "nice enough" gated neighborhood and since getting a TJ, I've had it rifled through twice (I keep nothing of value inside it, not even pocket change) and had the jack / gas can stolen off the back of it once. There are a lot of people out there who will just take *anything* they can get their hands on, and a soft-top Jeep is an easy opportunity.

I'm no expert but in reply to that guy asking ahout Wenkels as generators, I've read that a lot of their efficiency issues are solved by running them at a fixed RPM, and Mazda just recently patented a hybrid system using a Wankel engine. So maybe it could work?

In a series hybrid setup in a car, using a rotary engine to power a generator might have benefits such as a more compact generator set or weight savings. In nearly any other application where the size and weight of the generator isn't critical, it's not going to be worth anything over a piston engine that's either dirt cheap (small gas generators) or a diesel engine that's dead reliable (larger gensets).

They were probably aiming for the battery, but really anything that the five finger discount works on is the eventual target. gently caress I hate thieves.BlackMK4 posted:Is there an OEM source / application for Deutsch style 1/8"-27 NPT fluid temperature sensors? What resistance curve? I'd go on rockauto and use their search to look at all standard motor products coolant temp sensors by price, it's limited and will only give you one page of results but it'll narrow things down, then you can look through the pics till you see a close match and check what it fits.

Im trying to determine the source of some suspension noise on my 17 Volkswagen Golf. Is there any harm in spraying silicone lubricant on the bushings and other friction points to narrow down the source? I figure Ill do a part or a bushing at a time in hope that I actually find the source.

Whatever oil you choose, make sure it's compatible with the kind of rubber you're putting it on. The Cole Parmer chemical compatibility database is a good place to start. For example if you put silicone oil on natural rubber or neoprene it will make it fail very quickly, and if you put motor oil on EPDM rubber it will do the same thing, but silicone oil on EPDM is perfectly fine and motor oil on neoprene only causes slight discoloration. I would probably use motor oil rather than silicone oil if you insist on using an oil... Most of the materials on cars are going to be chosen to resist it since motor oil is always present in cars, if not always leaking. It'll damage some suspension rubber products but it takes a large leak for a long time to really get to them. Dish soap is probably your best choice though. kastein fucked around with this message at 05:05 on Mar 8, 2021 |

Extremely basic bitch question: I put my tools away for the winter. On Saturday I took out some of them to put up a shelf, and I noticed some rust spots forming. It's no problem for me to clean up, but what's the accepted way to keep the rust from forming?

Put a thin layer of oil (any kind will do) on them before you put them up.

I'll be cleaning up some rocker rust on my shitbox, and after wire brushing I just have an anti-corrosion primer I thought to hit it with, before doing a color coat. Stuff like PO15 wouldn't really work on a body panel, would it? Tbh that rust looks mild enought that I wouldn't even bother touching it. Otherwise I'd never be able to drive outside here lol

I have an insanely stuck bolt on the trailer hitch on my Volvo. I had to remove a bracket since the trailer light connection failed inspection. I cut the nut end off, but the bolt end was still stuck enough that it sheared off when i tried to free it with a breaker bar. I've drilled through it (only 6.5mm bit on a 10mm bolt though), heated it with a propane torch, used every type of penetrating fluid i have and tried to press it out with a two jaw puller. I've hit the bolt and everything around it plenty with both hand and full size sledges. I'm at my wits end now. I could maybe buy some new equipment, like a bigger drill/drillbit, welder, oxy torch or induction heater, but I'm not sure what would be most effective. There is quite a bit of plastic around the area. The existing drilled hole isn't straight either. Its the right bolt holding the ball hitch itself in this photo. It is broken flush with the drop bracket on both sides.

They're through bolts? A big goddamn punch held with visegrips and a really big hammer are your friends here. Punch it straight through now that you cut the head off and put a new one in.

I've tried that with a 10 pound sledgehamer. Wont budge, and the car is swaying on its jackstands, so I'm loath to hit harder.

I would think I put more than 1000 punds of force on the bolt with the two jaw puller, before the puller started to buckle and slip.

I think you can drop the entire hitch, right? That would allow you to secure it better and work some angles, maybe.
