I originally started this enquiry in the general section, but it’s been a few weeks since I last posted and have since realised I should have posted in the technical section, so I’m starting again and continuing the saga.
Panda classic 2009 , 70,000 on the clock suddenly started misfiring. With the help of Koalar and a code reader
Found P0300, P0301. Misfire cylinder 1 and general misfire.
Swapped plugs, coils, injectors around no change to codes. My next check was to compression test, but, with all the checks I had done, disconnecting and reconnecting the Ecu plugs , my carelessness resulted in two bent and then broken pins on the Ecu unit.
If anyone in the future should be reading this take the GREATEST CARE, when dealing with these two plugs and sockets.
What to do? Is the car a write off or do I source a used Ecu unit? Disliking to chuck something away that can possibly be repaired I sourced a new old Ecu and hoped it would be OK to clone, even though it cost me.
Meanwhile I did a compression test, although to a cold engine.
No 1:190psi No2:190psi No3:80psi No 4:160psi Now there’s a surprise I thought the codes said the problem was with no 1 cylinder.
Leak down test next, again to a cold engine
No1: 20% but with the radiator water boiling like a kettle.
No2: 20% can’t hear anything
No3: 80% air noise from intake, also air coming out no4 plug hole
No 4: 20% air from intake.
From that I think I realise that the head gasket has blown.
My thoughts are to take the head off and hope that the it’s just the head gasket and maybe the valves.
Does anyone have any thoughts as to the condition of the piston rings. I think to do anything with them is a step too far for me. No means of removing engine, nor the space to do so.
The condition of the engine oil as far as I can see from the dipstick is as clean as when I put it in.
Sorry to be a bit long winded
