    help engine making weird noise?????

    right first of all my turbo blew on my car and was passing oil through the intercooler and got up all the pipes right mess i got it all out of the intercooler best i could and then changed the turbo unit for a brand new one started the car up and it sounded like a bag of shit sounded like the spark plugs were hitting the pistons so i took them all out to check and it looked as if they had been hit by the pistons gap was closed on 2 plugs and the others were also marked what on earth would cause this bought a new set of plugs put them in and still sounded crap so just gave it some revs to try clear the oil in pipes and stuff and left running then the sound went away was driving for half hour fine pulling like a train then started making the noise again i cant get my head round it why the plugs would be getting hit by the pistons i have the right plugs ?????

    maybe you accidentally left something inside a pipe or a bit of the old turbo was kicking about. If the plugs are damaged then the tops of the pistins will be as well and the underside of the head/valves. Time for a strip down and find those extra parts. Just hope some of them have not gone past the exhaust valves and wiped out your new turbo as well
    Be Happy
