sandy_gray Posted January 12, 2007 Posted January 12, 2007 Hi tonight on the way to the ayrshire meet my car blew up and then went on fire because of oil on the exhaust.I was out overtaking a few cars giving it a bit of boot when at 6500rpm it made a weird noise my oil light came on,a 6 foot flame shot out the arse of it and i lost all power (think i lost oil pressure) The oil is only over the back left hand side of the engine next to the turbo and intercooler.It is 2 dark to see anything else other than things covered in oil. Does any 1 have any ideas what has happened. I am running a fair bit of power and 1.4 bar of boost on a andy forrest 20g turbo if this helps oh and the tubo is only few months old.I will take pics in the morning of it.Any help would be brilliant thanks[:'(]
drb5 Posted January 12, 2007 Posted January 12, 2007 Sorry to hear mate. Sounds like a rod through the block, on first thoughts.
Fab 1 Posted January 12, 2007 Posted January 12, 2007 Oh goodness, that is horrendous. Sorry I can't help but just wanted to say that I hope the problem is fixed really soon. Best wishes Jen
drb5 Posted January 12, 2007 Posted January 12, 2007 What year of car is it and had you been driving the car hard for some time? List of mods?
sandy_gray Posted January 12, 2007 Author Posted January 12, 2007 What year of car is it and had you been driving the car hard for some time? List of mods? The car is a 2002 wrx and no it gets a good seeing to once in a while but no not really Mods- 3 inch exhaust from turbo back,Turbo up pipe,Manifolds changed,bigger bosch fuel pump,20g turbo,fuel pressure regulator,boost regulator,sti pink injectors running at 100% when on full boost,ecutek remap,cooler running plugs, Large tmic
the squiggle Posted January 12, 2007 Posted January 12, 2007 It does sound like something has went belly up in a big way Very hard to conclude what has happened without looking at the car Holed piston due to MAF failure and the crankcase pressurising rapidly, blowing out the crankcase ventilation and spraying hot oil all over the hot turbo . 6 foot flame would come from the air accounted for by the MAF not being present anymore due to blown off hose and the excessfuel hitting a red hot cylinder. All very viable but until the car is viewed/disected all will be speculation
drb5 Posted January 12, 2007 Posted January 12, 2007 What sort of fuel regulator and what pressure you running it, considering the injectors are at 100%?
AlanG Posted January 12, 2007 Posted January 12, 2007 The oil is only over the back left hand side of the engine next to the turbo and intercooler Could be an oil pipe is damaged/has came off/ burst (feeding the turbo), causing pressure drop when oil has emptied from sump
colin_ross Posted January 12, 2007 Posted January 12, 2007 Was there any bangs when it happened? Did the car cut out straight away or did it idle at all after the flames? If so did it sound like a bag of spanners?
sandy_gray Posted January 12, 2007 Author Posted January 12, 2007 What sort of fuel regulator and what pressure you running it, considering the injectors are at 100%? 55psi as set by andy when he tuned it and its a greddy 1 And no the car still had a little power and was still able to drive all be at a very limited pace.It cut out though as soon as i took it out of gear
sandy_gray Posted January 12, 2007 Author Posted January 12, 2007 Im hoping its this simple as it would still have drove a little if i had pushed it but i did not want to do any more damage and i was on fire! (put it out with a 2 litre bottle of irn bru)
RA Dunk Posted January 12, 2007 Posted January 12, 2007 try over on www.22b.com, there good at all the technical stuff on there
scoobaroo Posted January 12, 2007 Posted January 12, 2007 Sorry to hear about your misfortune m8, hopefully the engine hasn't gone. You wont know for certain until you get it professionally checked out. Fingers crossed for you m8. Marty.
colin_ross Posted January 12, 2007 Posted January 12, 2007 If it was still driveable it would suggest something like AlanG suggested was wrong, blown off pipe or something rather than a blown engine. Hopefully nothing too serious
WUZ Posted January 12, 2007 Posted January 12, 2007 Yeah but 55psi is approx 3.8 bar and assumin that was set as a static pressure and he's maxing out the STi "pinks" (565?) on a 20G then your talking a lot of power going through a WRX block. Ticking time bomb? Might just be one of the breather hoses! but I doubt it. Get it looked at and let us know the diagnosis. Russell
sandy_gray Posted January 12, 2007 Author Posted January 12, 2007 Ding dong the witch is dead.Just spoke to greer sport i have dropped a piston and blown a hole in the crank casing which has burst the breethers off just like an air line going off.So R.I.P engine number 1[:'(] And the injectors were the 500cc 1s which are rated for around 400 Greer sport here i come i am awaiting a quote later today.
AlanG Posted January 12, 2007 Posted January 12, 2007 If it was still driveable it would suggest something like AlanG suggested was wrong, blown off pipe or something rather than a blown engine. Hopefully nothing too serious Not sure why you feel my "suggestion" is deemed to be "wrong", since at the time of posting, the only information with regard to the fault on S4NDY's car was written in the first post. At that point in time, no-one knew for certain what the fault was unless they had further communication outwith this thread. As more information came out on this thread from the owner with regard to what happened, after, my suggestion, the diagnosis of the actual fault on the car becomes clearer. As you will be aware from other contributors, a conclusive diagnosis would not have been possible for certainty without physical inspection of the engine bay.
chris_c201 Posted January 12, 2007 Posted January 12, 2007 AlanG - Think the post was actually agreeing with you, the "wrong" being in relation to fault..... may be talking rubbish but thats how i perceived it....
oobster Posted January 12, 2007 Posted January 12, 2007 Ding dong the witch is dead.Just spoke to greer sport i have dropped a piston and blown a hole in the crank casing which has burst the breethers off just like an air line going off.So R.I.P engine number 1[:'(] And the injectors were the 500cc 1s which are rated for around 400 Greer sport here i come i am awaiting a quote later today. Sorry to hear that. Hope it doesn't work out to be too hard on the wallet.
AlanG Posted January 12, 2007 Posted January 12, 2007 After the horse has bolted i know and no use to you now, but do you have any gauges in your car S4NDY which might have given you an early warning of something not quite right? (not that i give a toss about gauges when i'm givin' it full boonah!!) []
AlanG Posted January 12, 2007 Posted January 12, 2007 chris My suggestion has turned out to be wrong, but was given as an alternative suggestion at that time with the information given by the thread starter.
sandy_gray Posted January 12, 2007 Author Posted January 12, 2007 Thanks guys for the responces but no need to argue any information givin was gratefully recieved[] and Alan no i did'nt see there purpose really DOH![*-)] Anyhoo im waiting on the quote back from bill im just going the full hog this time so its going to be expensive but i want a bomb proof engine this time as i do tend to have a lead right foot.
AlanG Posted January 12, 2007 Posted January 12, 2007 Ahh... the 'ol slippery slope of further tuning... [] Would be a shame to build a bomb proof engine and stick to what you've achieved so far... [] I can hear your wallet whimpering just now..... [][] but hey... what the ****, you only live once! Good luck and enjoy it. []
st3ph3n Posted January 12, 2007 Posted January 12, 2007 S4ndy, get the 3.2 conversion. [] Alan - I think Colin was agreeing with your diagnoses. But you could read it the other way. The wonders of our fantastically ambiguous langauge.
AlanG Posted January 12, 2007 Posted January 12, 2007 Alan - I think Colin was agreeing with your diagnoses. But you could read it the other way. The wonders of our fantastically ambiguous langauge. Indeed. The written word can be misinterpreted, hence i sought to clarify my position to alleviate any doubts others may have had. [Y]
