Default gti getting 20ish mpg

let a friend barrow my car and he pretty much blow and rosted the head. well im in germany had the dealer install a head i ordered from the states, they did all new pulles and a bunch of other stuff. they said its not possible to take the pistons out without removing the block and splitting it... that or they didnt want to do this and said it cant be done and wanted lot$$ to pull it out and do it.

here we are probably 6months after that then let it sit for 8months for a deployment and i want to change the pistons, can i just pull the head and do it while the motor sits there like a v8 can be done? it should be the same as any other pistons in the world right?

also my knock sensor is acting up and while i cruise on the autobhan itll kick my turbo out and if i want it back on i have ot turn the motor off and bump it (pretty stupid thing at 130mpg at midnight and the lights get turned off for a couple seconds) any tips on this, i think its the wiring but not sure and the dealer couldnt figure it out.

You can pull the pistons out from the top once the head is removed. Just remove the oil pan and you can access the rod caps, unholy them and pull the pistons out from the top.

You can take the pistons out with the engine still in the car. The head must be completely off. then jack the car up and put it on jack stands. Take the oil pan off, along with the oil pick up tube, and everything else blocking the crank. (DON'T LOOSEN THE CRANK). Then take the nuts off the connecting rods. Next grab something long and skinny to put in the cylinder to push the piston up and out. Might have to tap it with a hammer to get it to move out. Don't hit too hard though.
