Hi
Well no luck with an engine to swap in place of my mates 12r so we pulled the old on apart and found it had swallowed something in no 1 cyl . Can anyone tell me or point me to the torque values for the cylinder head bolts and the crank journal and conrod bolts . Will try and put it back together this week .
Cheers
Chris

Hi
Thanks for that . Will get the motor back togther then he can go and find himself a manual for it . You never think you will need one until its too late .
He has taken a punt and got a second have 12r from a toyota and hopes to swap out a piston . Did Daihatsu change the block casting when they made there motors ? Whats with the casting over the flywheel etc . New to Daihatsu I am .
Cheers

Daihatsu never touched the petrol motors, they were supplied in long form direct from Toyota.
the bell casting on the block is only on the 12R, the 18R has a flat block end with no bell. You can get a extension housing to mate an 18R to the 4 speed box, but unless you plan to keep the rig for a while, it is easier to keep the little 12R in there.
