Arnold Posted June 26, 2013 Share Posted June 26, 2013 Hi all I've recently had my head gasket replaced as it was leaking, for an Athena 1.4mm one, but ever since then the car has mis fired on boost. More so around 0.1 - 0.3 bar but can happen at any time. I've changed the leads, plugs, rotor arm and cap but it still happens as I was originally told it was an electrical issue. I've noticed this morning that I've got quite a large oil leak down the drivers side of the engine. It's all down the side of the block and over the sump, looks like from the head gasket area. Could this be the reason why the car is mis firing? If not, what else can I check? The car was running fine before the HG was replaced. No error codes being thrown either. Cheers for any help Quote Link to post Share on other sites
turbo Grant Posted June 26, 2013 Share Posted June 26, 2013 Is the leak at the front on the corner? It's so easy to put the head gasket on the wrong way round Quote Link to post Share on other sites
Arnold Posted June 26, 2013 Author Share Posted June 26, 2013 I've got a leak on the front corner yeah, but it's minor. The main one appears to be behind the cambelt cover on the drivers side of the engine Quote Link to post Share on other sites
Danza V Posted June 26, 2013 Share Posted June 26, 2013 Possibly crank oil seal or pump oil seal and its getting flicked everywhere. As for the misfire :/ I'd just compression test it and see if its that mate Quote Link to post Share on other sites

Danza V Posted June 28, 2013 Share Posted June 28, 2013 They common on these mate. Take the pulley off and bottom cover and you should see no oil but if you do then it could be the above Quote Link to post Share on other sites
Arnold Posted June 28, 2013 Author Share Posted June 28, 2013 (edited) I had the timing belt cover off and could see oil coming from somewhere, but wasn't exactly sure Here's the plugs (Cylinder 4 - 3 - 2 -1 ) Edited June 28, 2013 by Arnold Quote Link to post Share on other sites
Arnold Posted July 2, 2013 Author Share Posted July 2, 2013 Done a quick video too so you can hear what's happening http://www.alanarnold.co.uk/video/Glanza_misfire-0112.wmv'>http://www.alanarnold.co.uk/video/Glanza_misfire-0112.wmv Quote Link to post Share on other sites
Xpect Posted July 3, 2013 Share Posted July 3, 2013 Maybe simply replace the Plugs? Quote Link to post Share on other sites
Arnold Posted July 4, 2013 Author Share Posted July 4, 2013 Maybe simply replace the Plugs? Forgot to post that i've replaced the leads, plugs, rotor arm and cap. She's going back to the tuners tonight Quote Link to post Share on other sites
Jhandy Posted July 4, 2013 Share Posted July 4, 2013 have the camshafts been put in correctly?, if not this can cause it to missfire was the headgasket completly flat when installed because if a metal headgasket has a crease in it, can cause a leak where it hasnt sealed correctly, or as grant said, it couldve been put on upside down another thing to check, make sure all of your injectors are plugged in correctly Quote Link to post Share on other sites
