Trying to figure out if my engine has been gone through before..
On the piston it says 020 and other numbers did not right them down.
dose that mean 20 over??? did the factory ever go 20 over? also it has a doubler roller timing chain is that orignal for a TA 340???
the front of the engine Lh bank says FW340sP31400092 the s is lower
then the other numbers whats that mean thanks
