My guess would be AFM.

The 'cooler had water in it, nuff said.

Mate, 2 things.

As a mechanic, i have seen plenty of engines that have taken in water. I have only ever once had one bend a rod. That was at high rpm, into a deep puddle.
Even with a cylinder full of water you think a starter motor could bend a rod? i highly dobut it. the speed that a engine cranks with water in a cylinder is very very slow. Most times, it wont turn, and if you try enough you will force enough water past the rings to get it to turn over. It wont bend a rod. if a starter motor could do that it would have to be very powerful.

When we test starters you get a peice of jarrah and push it into the pinion, to stall the starter motor to test the current at lock. a practice done by all auto electricions that i know of. and you know what. you can stop them very easily.

even if water got into the intercooler, chances are that the engine would have stalled first due to contamination of the air flow meter. especially with a hot wire meter.

The internet is not the right place to diagnose problems, not to mention by people who arent mechanics and who havent seen the wide variety of situations that a engine can survive through.

May i suggest, if you are interested in being a mechanic, you possibly start a apprenticeship. There are many things that defy every rule in the book, and there are just too many varibles to factor in.

What i say isnt meant in a rude manner. Im not trying to start a fight, but i just feel some things you say arent from experience. I have dealt with you many times before on the phone, proberly without you knowing it, and i know that you come from a automotive background, and have a interest in cars, and i respect that. but what you heard from "mates" or google tells you isnt always the full story, or correct for every situation.

Cheers mate,

Tom

What about if its running and it induces a cylinder full?

50/50 chance. I have seen both. as i said before, there isnt a text book case with cars. There are so many varibles, valve timing, how well the valves and rings seal, compression rator, engine speed, engine power. At idle, not likely. It will proberly stall first. At revs possible.

HA, HA, HA ^^ha ha ha That's some funny shit right there.

Forgotten something?? How about the reduction gearing of the starter pinion (8-12 tooth) & ring gear (120+ tooth)?
At minimum there's a 10:1 gearing (torque) advantage. Pretty freaking basic shit right there Mr Mechanic.

And your trying to tell me that compression testing a motor that HAS inducted water ISN'T best practice?.........Oh FFS! It would eliminate the basics i.e mechanical damage, rather than chasing non-existent sensor problems.

99 WRX/STI has a HOT FILM type MAF, not a hotwire, they were used <98. The design is based on the Bosch HFM5 sensor if you'd like to do play at home.
http://apps.bosch.com.au/motorsport/...rs_airmass.pdf See pages 3 & 4.

But hey, I'm just a lowly parts guy....WTF would I know

More parts "fitters" than mechanics floating around these days and being a fitter's not a hard job to do.

My job entails diagnosis of problems that mechanical muppets can't work out (and no I'm not calling you a muppet Tom).

This is my opinion, this is a public forum, where I'm entitled to voice my opinion to the best of my knowledge.
Please feel free to demonstrate where I am in error in my mechanical aptitude.

May I also suggest to you, that you don't need to be 'on the tools' to have a strong mechanical aptitude and that over 16 years professional experience, combined with over 20 years personal hands on experience, may have taught me more than 4 years in a class room & changing oil for a living.

Cheers mate,

Rossco

*Have you ever cranked a engine over with water in the cylinders??

*Yes you are right they dont like water. Sorry for the mistake in wire vs film. It is easier for simplicity. GOOGLE MUCH??

*Two things. I am a mechanic, but my real job is diagnosis. Now i barely touch tools except a multi meter, 1/4 drive socket seat and scan tool. I also like to feel my job is worth more than it is at times

You are correct, you are also good at google.

Please feel free to demonstrate where I am in error in my mechanical aptitude.

*I don't doubt that you have done many jobs on cars over the years, a bit of a hobby for a lot of people.


Now at the end of the day it is all in fun. I dont want people to hate me, nor you. Really it is just pulling the piss more than anything in a fun PWRX kinda spelling grammar way.

Tom,

Google....LOL! You don't seem realize that the I already have the knowledge & the simplest way to share it is to show people where they can increase theirs, using a search engine to find the relevant data isn't a crime buddy.

I already knew what a hot film sensor is & how it works, I simply added a reference for you, so you could increase your knowledge (if you wanted to) beyond the basic Tafe teachings.

Just because you qualified 2-3 (?) years ago that isn't the be all & end all, there will always be someone who has a broader range of knowledge & experience.
I was going through my Mazda rotary phase when you were 8 years old (I was 20-ish), that included porting my own housings and building up a 13b bridgeport in my parents garage (Much to their annoyance ), yep this unqualified dummy built a 'black art' engine when many shops were too scared to service them.

I've never said or think that I know it all. I personally look up to people like Doug, Sean and a few others around the place who know a shed load more than me, because they've invested the time to own what they know.

If they want to tell me I'm talking shit or just plain wrong, then fine, I'll listen.

I have no ill feelings at all Tom and hey, how about introducing yourself to me if you ever call Giant's, I might be able to save you some $$.

Did you ever make up that jumper harness from the airbag I gave you?

Haha, i know that it is you when i call but have never said so. A few times i was going to but then i decided that i should keep work to work, if you know what i mean.

Did you ever make up that jumper harness from the airbag I gave you?

Sure did, worked very well, they are both the same single stage airbag design, and dispite different shorting connectors, the plug in the airbag were identical so i didnt have to modify the harness. Now the shorting connector is in the socket in the harness to the bag rather than the bag itself.

Cheers mate.

Tom
