Default Drove my 02 for the first time today

Hey guys, I took my wrx out for the first time today. I noticed there was some white smoke that was coming from the turbo area. I just replaced the coolant line to the turbo and there was some antifreeze that spilled so Im wondering if that could be it? It eventually went away but if it comes back then what should I look at? Just a few things to keep in mind:

-Various gaskets have been replaced
-it hasnt been driven in over a yr til today
-there's one new piston

Is there a break in time that I need to give the gaskets or piston before I can get into the throttle?

Also noticed the car had a cheap oil filter, I'm goin to put some rotella 5w40 oil and a mobil 1 filter.

Thanks

1. Swapping to a Mobil 1 filter vs a "cheap one" is not doing your car any favors. Are you a tribologist? Do you know that the best filter for your car runs $300? Do you think your $8 filter will be better than a $3 one? You are lost on this subject, so quit trying to make up facts to suit your OCD...swap it out if you like, but don't use convoluted logic as the stepping stone for doing so.

2. Any new motor has a break in period and you can get that information from:

a. your builder
b. your owners manual
c. our search engine as we've discussed this here 87^25 times since Lincoln was in office.

3. We don't care about things that go away and aren't going to second guess what ifs....if and when the smoke returns, then go back to who did the original job and seek resolution with them as I can list about 285 things that will cause smoke and the fact is we don't know as we cannot diagnose things via the internet.

Woah easy man.

I just thought i'd get a mobil 1 filter because i figured it would be better than the one thats in it right now, but if its not then i'll leave it no big deal. Also the engine isnt new, a piston was replaced and a few gaskets as well...I dont have any way to contact the previous owner. I don't have an owners manual but will be getting one.

It was just a simple question. Also I dont know if it's just the app or what but half the time I use the search on here it doesnt provide me with useful info/displays threads that arent even related to the topic I searched.

Damn,
When I read Unabomber's post I thought it was Uncle Scotty.

Just drive the car gingerly to be sure it doesnt explode. Keep an eye out for smoke and enjoy your new to you car.

Thanks man I appreciate it! I was thinkin about taking it to the local tuner so that they could look at it for me since I dont have the tools/knowledge to dial everything in.

Wow, you are rude. When did he say he was buying a high performance filter? I didnt see anything of the sort, all he said was that he is putting in a Mobil 1 filter to replace another cheap filter, not "Mobil 1 is the best filter ever" like you seem to think.

Just bought an 02 WRX three days ago. Of course people new to this platform are going to have questions. Chill out man, jesus.

What was the point here again? Instead of arguing with someone who knows what they are talking about or trying to call him out, why not try and answer the silly question?

New to the car? We have a newbies forum. We also have COUNTLESS STICKIES at each forum to help the lazy. NASIOC also provides a "search" function that works decently, and of course there is Google.

We don't know what gaskets you replaced. So we cannot help you. Generally the answer is no, but depends on what gaskets. Being as a piston was replaced, and the motor is likely a rebuild, yes you should do some sort of break in. What kind? Google, as everyone has a different idea.

Why was only one piston replaced? That sounds absurd.

The car was in a front end collison so the previous owner took the block apart to check for damage and found that one piston had a hairline crack. The engine isnt a rebuild, I think he just replaced a few preventive gaskets but im not sure becuase I have no contact with him. I will be taking my car to a reputable local tuner soon to find out exactly what needs to be done but I started the car yesterday and let it run for 30mins, then drove it to the gas station to put some 91 in, everything seemed pretty sound to me

Unabomber, i respect you and your opinions immensely but CHRIST..he was just asking some questions.

Sure its annoying to get the same dumb, misinformed questions from us new subaru owners on these forums but no one is forcing you to answer them.

Attention asshats:

If you want your hands held and your bottoms powdered, then do the following:

1. Post in the Newbies and FAQ forum
2. Post in the Newbies and FAQ forum
3. Post in the Newbies and FAQ forum

These are the tech forums....this is where you wear your big boy pants. You READ the sticky threads at the top of the forum. You SEARCH using our search feature. You use a COMPUTER and not your damn cell phone or the crappy NASIOC app on your phone. When I have an important question, I use a computer as that's the right tool for the job. Not saying you can't use a phone here, but for God's sake, don't use the phone/app as an excuse for not reading the sticky threads and searching.

If anyone doesn't like it, the door is that way and we'll refund your price of admission.

You moderate on a mediocre car website. Quit the elitist guise and be a decent human being.This could be some 17 year old kid who just got into these cars and this site and misplaced a forum topic (the horror!). Easy mistake. it doesn't benefit you or anyone on this site when you belittle the people who bring activity and attention to these forums and keep this place alive.

In what ways exactly? I mean, it's so mediocre you joined, post regularly, and we have hundreds of sign ups a day.

Any port in a storm. Of course one would join a website where inexpensive used parts are sold and information about common problems is readily available. Doesn't make it an overly well done site.

Anyways, i was more so taking a swipe at the arrogance commonly seen in you moderators. Being a dick to someone who made a small mistake in a post location is unwarranted and childish.

Hmmm funny, almost every WRX owner or shop owner that works on them has insisted that I don't cheap out on oil filters.

OP:
Any time an engine is taken apart there's bound to be oil, coolant, penetrating oil - all sorts of crap - all over the place. Probably even some of the mechanic's coffee here and there. When that stuff gets hot for the first time (ie, running the motor) it's going to burn off - and usually smoke. If you just did the coolant line off the turbo, that could have resulted in some residue as well.

If you've ever seen even a brand new motor fire up and run for the first time after an install, there's usually some smoke from machining oil/fluid spillage on the metal burning off unless it's meticulously cleaned off first.

Nobody here can say what you were seeing or where it was coming from, or if it's a major issue or not. If it went away, don't lose sleep over it. Just check your fluids regularly and poke around under the hood now and again to check for leaks as you would any other car. Identify and fix any problems as they come.

To play it safe, stick with the break-in period described in your owner's manual - even though it's really weird that they just replaced one piston...seems kinda halfassed to me. While you're there, why wouldn't you do them all?

Thanks for the info! Good stuff.

The car has 86k miles on it and when it was pulled apart he said the inside was in very good shape...he only replaced the one because it had a hairline crack from a previous front end collision. The smoke has not been present since the other day when I drove it for the first time. I've been starting it everyday and letting it run for awhile to try and see if anything seems off but as far as I can see this thing is ready to be driven over to the tuner to see what he has to say. Alot of the wrx's I see for sale on CL have been tuned by the shop i will be taking mine to also.

Take it from me you have no clue what the owner actually did, he could have done one thing and said another. I would do an immediate oil change drive nice and easy for a bit. Change tranny fluid. Scan the ecu for any codes that might be hiding.

Thats true. The guy was very honest though, he was an older guy and he has done body work and repairs now for I think 26 years... But thats why I'm taking it over to the tuner to see if anything might be off and also to get some advice on which route I need to take to get to 500hp which is my overall goal.

Man 500 hp is a huge jump for the ej20. In all reality I would build a 4g63 block in an evo as the stock block will handle a ton of power. These aluminum blocks in the ej will only hold a certIn amt. realistically stick to 350 hp tops unless you plan to spend another 2k-4k with on the block with fully forged internals plus new gears clutch flywheel etc.

Yeah I was planning on tearin down the engine next spring and going with the 2.5 block, built internals and everything. I'll probably only do a few things to the 2.0 maybe a downpipe and a tune to hold me over til spring.

Lookin at goin with a gt3076r turbo probably but i'll see what the tuner has to say!

Trouble codes don't "hide". They're not sneaky little electronic gremlins hiding in your car waiting to pop up and ruin your day. And not having any stored in the ECU tells you next to nothing about an engine's health.

That's not a Subaru thing, it's an OBD-2 thing. Any USDM vehicle from 1996 to present functions the same way.

If all of the readiness monitors have run and passed, there's either a DTC set (which triggers the MIL) or there's not. There could be a "pending" trouble code in certain cases, which means that the ECU has seen a system functioning outside normal, allowed parameters and is waiting for another test cycle to see it occur again before triggering the MIL. There may also be history codes. Those are codes that have set and weren't manually cleared/reset. Once the ECU sees a system functioning normally through an appropriate number of test cycles, it automatically clears the DTC, turns off the MIL, and stores the code in history.

"Scanning" your ECU for codes is NOT a magic indicator of an engine's health. Period. Your ECU couldn't care less if you were sending your main bearings into geosynchronous orbit, or low on oil, or hemorrhaging every fluid in your car all over the ground. A trouble code will ONLY set in the case that a malfunction within the fuel, ignition or emissions control system is causing the vehicle to output greater than the federally allowed emissions standards. If it's not polluting, or might cause it to pollute, the ECU doesn't care.

I can't tell you how many times in my past life as an automotive service writer (8+ years, thank you) I've had customers come in with a HORRIFIC knocking noise coming from their engine, only to have them say to me: "Well... The check engine light wasn't on, so I just figured everything was okay."

So when you plug in and see "No Codes Stored" don't just assume that's the all clear to go out and flog your car. Stop spreading myths and misinformation.

If you go to your tuner and tell him you're looking for 500hp out of a 2.0, he's probably going to laugh at you, or his eyes are going to spin around in his head and turn into $-symbols. Be prepared for that.

You're going to have to:
a) Tear the 2.0 down again and build the snot out of it, plus spend a heartbreaking amount of money on parts.
b) Do an STi swap or a hybrid build - and then spend a heartbreaking amount of money on parts.

There's a really well written sticky in the Newbie/FAQ forum: http://forums.nasioc.com/forums/show....php?t=1393580 <--- Read it, and then reconsider your goals.
