I Thought I Had Blown The Engine ...

Here's a short story:

Just took the skyline for a quick spin to try a new fuel map.

When there was no traffic I floored the pedal a bit more (about 4000rpm) ...

The car started to move forward and came on boost - suddenly - BANG!

Yes! BANG!

:wacko::unsure:

OMG! (It was a very loud BANG!!!)

What had I done?? (my fuel map wasn't that bad, was it????)

I rolled (engine died off) to the left and opened the bonnet, but I could see no damage ..

So I started the engine again (and secretly hoping that everything would be fine)

, but it ran very, very poorly.

Also I could barely keep the revvs over 3000rpm and the engine would die off often.

The car made a lot of black smoke and noise either ...

A nightmare!

In 3rd gear and with a lot of smoke and sweat I made it somehow home.

(I was just 3km away anyhow)

With a flash-light I checked under the car and could find no oil leakage or obvious damage.

Again I opened the bonnet and there it was ->

The newly fitted hose joiner had come off .. :)

PHEEEWWWW! Seems it is my lucky day!

(Thanks for listening)

Ohhh ... I see what you mean!

Thanks!!

Given where the clamps are on the hose, and how long the pipe/lip is - doesn't look like it was done up correctly.

Make sure you get the clamp behind the lip this time around.

It was my first time ;), and I just recently fitted a new turbo ..

So I really thought something massively wrong has happened :)

Obviously I made a mistake while mounting the clamps..

Nonetheless interesting to see that there is actually much pressure at work ..

I will have more respect now for the PSI figures!

Yeal lol thats happened to me heaps of times so loud you instantly think shit what have i done then the csr idles like a rotary.

pretty common occurrence

you can unplug the afm if that happens, it will limit revs to about 2500 but it drives a bit better than with it plugged in (reverts to a default map)

one time my r32 spat the whole lower half of the hot-side pipe (from under the airbox to the fmic) into the bushes

i couldn't find it so i had to limp it home :(

wait till you get one come half off, it runs like shit on boost but idles fine and drive fine off boost and cause it only came half off you can't see it easy and have to pull half the friggin car apart to find it was the one that joins the back turbo to the front one :rant:

I blew my cooler hose going through the NATO park near stanwell tops, I also herd the bang and black smoke, All my intercooler pipes seemed fine and I started to worry that it was something else, I decided to remove my front bar on the side of the road (had to wait for dad to bring tools which took him 2hours to get to me) and the pipe going into the passenger gaurs was off.

Massive pain in the ass especially if it's hard to get too !

How good is it though when you find it - that sense of relief that it was nothing serious :) Although the bogans in falcons/commodores flying past while your bonnets open and they scream out piece of shit skyline is annoying

i've never once had a cooler pipe blow off in 4 years, last 2 years at 20+psi. best clamps ever, apart from those fancy wiggins ones....

Use these, everything else sucks.

Agree that blowing a cooler pipe off scares the shit out of you, sounds like you put a piston through the block and then it won't idle, worst feeling ever.

Hi,

Yes, now that I know it is common it is -> LOL, but yesterday it was -> OMG!

I have a Nistune ECU and I was trying a new map ..

LOL good read, very common.

Get that car tuned properly with the new turbo as the stock ecu may just blow your motor.

That's good information, had I know I would have had less stress ..

It was difficult keeping the engine alive and it would not take any load at all.

      Diagnosing with and without is mostly the same. You need to know, as Duncan asked, and what conditions. Car hot, cold, idling, driving, if while driving what rpms, is when you're varying, or is it when held constant.   From there it's understanding what can be causing it. Starting with pretending all of the sensors are correct. Which means if it's going rich, why would it be thinking more air is going in than it is, and under what conditions. So things like if only when under boost, it could be be a loose intake piping joint. It's just understanding the system, and understanding when/how the problem occurs, and then if it's only occuring in specific scenarios, what can be causing it.   ECU specifically, if it's aftermarket, it'll have software you can use, for the Skylines on factory ECU, there is Nissan Consult you can use. Most ECUs have a way to get data from them.

      How do you go about diagnosing ecu's that don't have data logging, is it more experience at that point and just trying out things that you think will fix the issue?

      Stock O2 are basically useless beyond anything at stoich. Any misfire will also be seen as lean. The stock O2 also read a collective exhaust gas volume, not each cylinder. Sputtering and missing means not each cycle is firing, and some are. Which means even if rich, as shit, on cylinders as they miss, they'll read lean, but the cylinders that did fire will read rich, and combined, well, they can read anything from rich to lean.   Start with the basics before even going looking at sensor values.   Edit: I say the above, and that's coming from the guy with a few thousand dollars worth of scan tools sitting right beside me right now that I use frequently for my job.

      I’ve heard it can be done, you need to redrill the holes where they bolt to the chassis and apart from that they are the same. I’ve never done it or know anyone personally that has, it’s just something I’ve heard
