Hello. new to the forum so apologies for any mistakes.
Vehicle is a 2004 megane 2. 1.9dci f9q engine.
A long story but the original fault was check injection showing on dash.
Plugged into diagnostics which showed glow plug fault.
Called mobile mechanic to replace glow plugs. found no2 glow plug to have the tip stuck in the block.
the mechanic has knocked the tip through in hope it will get broken up and out of the exhaust.
He's then turned over the engine and greeted with knocking from the engine. approx 10 seconds switched engine off.
Came back next day to take the head off and remove debris. no 2 piston showing signs of wear. no holes but scratched and metallic silver colour compared to others. he has told me this wasn't due to the glow plug going through but the damage it has already caused by overfueling in the cylinder .
Checked head for any damage and concluded no damage to valves etc. although was in the dark.
Started engine and seems fine. no knocking, idling fine etc.
He then spots oil loss and realises a seal has come off the turbo return pipe upon refitting. after replacing the pipe and oil he then starts engine again. it now has hardly any power. and low idling. taken to an injection specialist who has performed a compression test to find no compression on cylinder 4. or as I'm told no1 as French are reverse order. so no 2 (or 3 ) is where the glow plug went in and no 4 (or 1) is where there is no compression . I'm told the glow plug incident wouldn't cause no compression on another cylinder. so my question is.. what do you think could have happened to it.
Do I give up and scrap the car. or do I try and fix the problem? thank you in advance and please ask if you require any further information .
