I have a tsx v6 with a sri and a jpipe long tube
a few weeks ago I hydrolocked (I have a cai set up at the time) I swapped out the oil for full synthetic mobile one as it was the only one I found that was 0w-20(it claims to be for improved mpg). We had to change the oil a few times to get the water out of the engine. Im getting about 3-5mpg less combined per tank since then. Is it the oil? or is it possibly that something is messed up from the hydrolock. I took it to the dealership after the water had dried and they found nothing wrong with it although I don't think they tested the compression ratios.(my warranty was no voided as they found no traces of water even with my mods)

get that compression test done

In my experience most engines that have hydrolocked are done for. IMHO I think your on borrowed time. I would get the compression/leak down test down. I would also check your valve train too.

Misc-ura

I'll check the compression on it but I remember taking it to the dealer and asking them for a valve adjustment and they told me the car didnt need it and that if there was an issue within the engine that the ecu would be flashing codes. Its been about 1000 miles since the hydrolock and besides mpg she seems to be running alright. And also I had a friend who also hydrolocked and his srt4 and he got the water out of the engine, it has been running the past 30k miles problem free since.

Where can I get a compression test done?

TrojanTSX

Ya about those ECU codes.....I miss-shifted my Civic Si three times in a row, went well over the limits of the tach and the motor didnt blow until 6 months later. My car never threw a code, yet I floated several valves. The ECU said that I had over revved to 13K the day my motor blew which I never went over 6K that day.

I hydrolocked my Escort motor and a year later my oil pump failed because of the water. I put 25K miles on that motor in that year of driving.

If I was going to have a compression test done in the DFW area, I would go to Cobb Tuning. Find someone like that in your area.

Misc-ura

Alright I'll take my car down to Tony Fuchs to get her checked out. Damn this might cost me an arm and a leg.

its rayden

what else was replaced/changed after you hydrolocked?

Misc-ura

Thats it, the spark plugs were fine and i took her to jiffy lube and they told me the transmission fluid was fine too, just changed the oil twice. Then took her to the dealer since i thought i heard valve tapping but they said thats just how the j series sounds at idle and that everything was fine

TrojanTSX

Number one reason why I never will have a cold air intake on my cars. We get flash floods here in DFW all the time and ponding of water like crazy. I have seen too many people hydrolock their motors here that its not even funny anymore.

I hope everything turns out well for you tho!

Misc-ura

Thanks, I had a cai because i live in cali but there was a storm while i was caught in a city with very poor drainage. Everywhere I looked there was water until i had no choice but to go through a puddle and then bam car turned off

Ahhh, Jiffy Lube. From here on out you won't know if your problems are water related or due to letting a Jiffy Lube employee within 1500 feet of your car.

^holy crap

fuck jiffy lube, what asshats

its rayden

why would you bring your car to jiffy lube...

ceb

Here is a post about some personal experience of mine with Jiffy Lube.

For those of you unfamiliar with Audis, the transmission has no dipstick and a tranny flush requires specialized tools, access to a computer and about 3 hours. The tranny fluid must be at a certain temp range and is impossible to get done at any quick lube joint. Audis also use special coolant and the regular green stuff will turn to a brown sludge in a matter of minutes.

Another coworker (just within the last week) told me that he nearly lost his belly pan on his Civic Hybrid. It turns out the Jiffy Lube place used only 3 clips to put the pan back on.

Misc-ura

That worries me a little bit but the jiffy lube I went to is actually run by a personal friend of mine who tunes cars himself. They didnt do much, all they did was change the oil and filter(i didnt want to have to find a place to recycle the oil myself) and they checked the tranny and told me it had too much transmission fluid in so I took it to the dealer and they said it was a little too full but they checked it and said it didnt need to be replaced. I am going to call up evasive motor sports and tony fuchs to get quoted on a valve train check and compression test. Anything else you guys recommend?

you're doing it wrong.

Please post MPG and your average MPH, both can be found in the MID.

Misc-ura

Average mpg 19.8 mpg(when I hyper mile I use to get 25.5 on an average tank I use to get 22-23)
Average mph 27

ceb

Here's what you do. At a time with traffic, find a gas station right near a feeway on-ramp and fill up your car. Reset the trip A odometer. Get on the highway and set your cruise to 55mph. Drive for 20 miles and note your MPG and MPH (your MPH should be around 45-50) Resist the temptation to scoot around cars that are slower but try to pass them without turning the cruise off or touching the gas pedal.

Once you've noted that information, drive back the way you normally would and post that info too.

If you don't have a gas station near an off ramp, then just reset the trip odometer once you've entered the freeway and have set your cruise.

Misc-ura

I will try this out thank you.

Misc-ura

Results
outside temp 68 degrees at night
Cruise control run
38.9mpg and 54mph avg
Regular run
33.3mpg and 72mph avg
Bare in mind I have a v6 and also this makes me think that it might be the heat that gave me bad mpg bc we have been in the high 80s in cali the past month

ceb

Another mystery solved. Well done.

The V6 gets great gas mileage on the highway (as evidenced by your 55mph run) but the city mileage is pretty dismal. Most of us can beat the EPA highway numbers but we'd be hard pressed to match the city numbers.

This doesn't prove that there isn't anything wrong with your car following your attempt to see if the TSX doubles as a submarine, but it resolves your mpg numbers.

Take your car to a trusted indy and have them give it a good once over. Anything you spend there will be far less than the cost of a new engine.

Thank you, CEB.

as he said, your car is running GREAT!
MPG can be affected by tires, oil(albeit a little), weight (if you're a hoarder), etc.

ceb

Fixed it for you

Yeah, those highway numbers are really close to what I get. My mpg is around 20ish with about 90% city. Not sure about my avg mph though, but its pretty low.

Misc-ura

Yea I'll still call my mechanic and see what he recommends I do thanks for the help guys and yea my city mpg must be horrid to bring a 33mpg average down to 19 on the tank

opboarding

I checked out my avg speed vs mpg this weekend and here is what I got. Yours still seems a bit low judging from what I got.

18 mph avg was 20.3 mpg
19 mph avg was 21.0 mpg(a few days later)
