ali_shaikh22 Posted September 24, 2013 Report Share Posted September 24, 2013 HiI have a Vw lupo 1.4 16V Automatic with 88K on the clockRecent work includes:BrakesFull serviceI was driving along on the M1 around the 60-70mph mark when i heard/felt a small hiccupThe car lost all power/drive and i was stranded on the hard shoulder.When the AA guy arrived, he advised the engine had no compression. I tried to start it a couple of times and figured this.AA took off the belts cover and the belts were fine.Then started taking out the spark plugs and found that spark plug number 2 had been squashed.Pretty stumped, parked the car up, not knowing how to progress this.Get a new engine, or do an engine rebuildMy question is, how can the piston crash into the spark plug when the con rod is holding it?Is this a common issue? as anyone seen this before?Will my head be warped? seeing as how there was no belt jump, the head gasket seems fine ( correct levels in water tank)Would i be able to simply replace a few parts and get the car going again?Any help would be much appreciatedThank you Quote Link to comment Share on other sites More sharing options...
Chrisbee Posted September 25, 2013 Report Share Posted September 25, 2013 Have you tried change the plug and starting it?, the car should still run on 3 cylinders so the fact it wouldn't restart tells me it wasn't the piston hitting the plug (impossible without smashing a valve too)If they're is no compression in on of the cylinders you may of blown an hole in the piston.Won't know for sure until you whip the head off.Have you run a diagnostic on it? Are there any dash lights on? Quote Link to comment Share on other sites More sharing options...
ali_shaikh22 Posted September 27, 2013 Author Report Share Posted September 27, 2013 MorningThere are no engine lights it all looks sort if normal when trying to turn over.So should I try putting all plugs back in and try to fire it up? Or leave the plug from cylinder 2 out?Would I not cause further damage?I imagine if the piston did hit my plug it would have caused further issues to the head too?Is there an easier way to check the piston?Are you aware of any writeups on removing and replacing the head?Thanks for your advice Quote Link to comment Share on other sites More sharing options...
ali_shaikh22 Posted October 8, 2013 Author Report Share Posted October 8, 2013 HelloI've put the plugs back in an tried to start, but just doesn't crank, won't turn.Do you think a new engine or a new head? Or maybe I just have to wait to see what I find when I start to strip the engineAny other ideas? Can I try and start it without piston having a plug?

V double U Posted October 8, 2013 Report Share Posted October 8, 2013 Get a long screw driver, and take out spark plugs 2 and 3, put the screwdriver down the spark plug sockets and see if there is any difference in how far it can go down... You should easily be able to tell if there's a hole in number two... If it's not cranking now are you sure the battery isn't dead? If the battery is fine it's looking like it's got a Leg out of bed (chucked a rod). If the piston had hit the valve and number 2 cylinder was on compression stroke the damage to the valve won't be as severe as if to say it was on exhaust or intake stroke as the valves would have been wide open (depending on prise time of collapse). If it's chucked a rod I'd look into the servicing of the car... When the oil was last changed etc. Hope this helps! Quote Link to comment Share on other sites More sharing options...
V double U Posted October 8, 2013 Report Share Posted October 8, 2013 Also, wap a Torch down the cylinder because if the piston is near TDC you may be able to see the crown ? Quote Link to comment Share on other sites More sharing options...
