does anyone have a drawing showing the route the oil takes through a twin cam motor....I am wondering if after the pump does it split and send some through the filter and then to the lower bearing and send the rest directly to the lifters and up to the heads...it seems that some where I read that it does...but it may have been on some other motor..memory ain't what it used to be...

 

here's a pic...

 

It filters the oil before sending it through the motor to lubricate, different from all predecessor motors that filter after it has gone through the motor. The service manual section 3.3 Engine/General Info, explains exactly how the oil cycles through the motor.

 

Much easier with pictures though

 

There are several pages of pictures along with the written details.

 

thanks guys

 

Big right up in my workshop manual,but no piccies.
