Well, they're mysterious to me! I have three questions in the following:
I can't seem to find any reference to these pipes anywhere on this forum, although I'm sure I've missed something ... what do the lines in the photo do? They exit low in front of the oil filter mount. See attached pics.
I thought these pipes might indicate the once-upon-a-time presence of an oil cooler, but I came across threads with people asking about coolers and where to install -- so I assume these pipes are not for a cooler. Also, there seems to be a big size difference between inlet-outlet (or outlet-inlet if you prefer) and the larger of the two pipes has only a hose clamp -- in my mind, not very secure for high-pressure/high-temp oil lines.
Q1: I have two 1UZs and both have the piping. Can someone tell me what they are for please?
Q2: Also: how do you get the larger of these pipes off? Once you have the single bolt off (easy), there appears to be a grub screw holding something in place internally. Only problem is that, on both motors, the grub doesn't appear to have any means of undoing it (no hex head, for example). Red arrows on the pics point to it.
Q3: Also: Have attached another pic of the back of the intake plenum (IMG9123.jpg) -- what does this pipe do? One motor (UCF20) has it, the other (UZZ30) does not.
Cheers in advance,
Mike
