Can anyone tell me if they have heard about core plugs coming out of the cylinder head of a 996 3.4 engine and what is the cause.
This has happened to my enigine on a run a couple of weeks ago and the only saving grace was that I was going slow at the time or the damage would have been a lot more than I have now.
The garage has said that the core plug in the head between cylinder 5 and 6 came out dumping the water in the the oil separator and then back into the engine intake side filling number 6 cylinder with water which hydro locked the piston on the upward stroke. result is the con rod for nimber 6 is bent like a banana and a couple more may be damaged also not the full extent of the damage has been given yet.
The engine block has been sent to Hartech for measuring of the bores to see if new liners are needed but the initial problem has me worried because if they replace this core plug could it happen again to another one.
Has anyone had or heard of any similar problems with the 996 engine
Thanks
