Gti 6 blown up? - Jaymes306 - 12-03-2014 My 6 decided it wanted to blow upon me the other day, was driving normally and all of a sudden a strong jolt with lots n lots of white smoke. Evan chucked some oil out (unsure where from yet). Isnt dropping oil now, does start just but sounds like a bucket of bolts. Piston 1 3 4 blowing 11's on a compression test but number 2 is 0. Not evan huffing when I pulled the tool away. It did suck up some water during the floods and died for the night wondering if thats the cause, ideally I need to know what the problem is. Head or bottum end? Cheers RE: Gti 6 blown up? - Andy! - 12-03-2014 tbh the first thing I would be doing is taking the head off and seeing if a piston is floating around in there. I certainly wouldnt be trying to start it again. RE: Gti 6 blown up? - 7057sam - 12-03-2014 Yeah definitely the water getting sucked,bottom end I reckon sounds like mine Does it rapidly over heat aswell,could be a sign the heads gone aswell RE: Gti 6 blown up? - Piggy - 12-03-2014 As said, no way of knowing really till you whip the head off... You done the right thing initially. If you can bare to run it for a few minutes, I would watch the header tank/rad to see if it bubbles or smells much RE: Gti 6 blown up? - Jaymes306 - 12-03-2014 Cant keep it running long enough to find out, dies shortly after starting. Didnt have any oil pressure or temp issues before it clucked out RE: Gti 6 blown up? - Piggy - 12-03-2014 Does sound bad. I would whip the head and sump off to investigate further. Then make a decision. RE: Gti 6 blown up? - powerandtorque - 12-03-2014 If the compression test result is literally zero then something quite fundemental has let go. Was it a tapper? Valve head dropping off would be my best guess if so. If there's zero compression I wouldn't bother running it upto temperature - just pull the head off and you'll see the issue straight away. Can only really be a bent/broken valve, a holed piston, or a catastrophic head gasket failure to give literally nothing (and even the HG would normally show a small amount of compression) RE: Gti 6 blown up? - Jaymes306 - 12-03-2014 Wasnt a tapper, was the smoothest running 6 ive ever seen. Evan had a full rebuild at pug performance 5 years ago but yes im tempted to pull the whole lump out tbh and work on it in the garage RE: Gti 6 blown up? - Jaymes306 - 12-03-2014 Ill be getting on it tomorrow and coming back with an update RE: Gti 6 blown up? - Niall - 12-03-2014 Water sucked up then bang and loss of compression. Sounds a lot like Matt when he shat a rod! If that's the case, that engine is basically scrap. Usually though if they throw a rod, it comes through the crank case and makes a mess everywhere!! RE: Gti 6 blown up? - Matt-Rallye - 12-03-2014 I'd be underneath it finding out where it dropped the oil from. My guess is theres a hole somewhere there shouldnt be when something shot out RE: Gti 6 blown up? - Jaymes306 - 12-03-2014 I did think that but it only lost a small amount of oil and its still full of oil now on the dip stick and guage? RE: Gti 6 blown up? - Matt-Rallye - 12-03-2014 Odd one but i would definately be whipping the head off to check the lack of compression. Hope its not terminal RE: Gti 6 blown up? - Matt - 12-03-2014 This sounds all to familiar..... I ran mine through a flood, it taped like crazy after. White smoke and wouldn't start. Once dried it was still a tapper, took 2.5k miles for it to shit it's rods RE: Gti 6 blown up? - Jaymes306 - 12-03-2014 Hmm, mine never tapped before and tbh it makes about 100 differant noise's when its running now lol RE: Gti 6 blown up? - Jaymes306 - 19-03-2014 Forgot about this thread, Problem turned out to be a 5" by 5" hole in the back of the engine, Lost half a conrod by looks of it along with the oil sprays! RE: Gti 6 blown up? - Paul_13 - 19-03-2014 Bugger! RE: Gti 6 blown up? - Jaymes306 - 20-03-2014 Re: Gti 6 blown up? - kentiiboii - 20-03-2014 Nice hole you have there. That's a shame RE: Gti 6 blown up? - Paul_13 - 20-03-2014 I've got a spare bottom end minus sump RE: Gti 6 blown up? - Jaymes306 - 21-03-2014 Ive got a new engine from pug performance already chap :p
