A better idea is to put a threaded hole in the rocker cover being careful to recover the drillings. Then fit the fitting to take the oil return plumbing. I did it on our 1HZ when fitting a bypass filter 10 years ago and all is well. If there was a leak then at least it can be easily seen during routine check ups.

Hi al, wouldn't like to drill a hole, bits of steel inside the sump wouldn't br flash. Have heard that DTS installers use a spike to puncture a hole into the sump. Mine was removed and drilled, this would be the idel scenario for piece of mind for me.

When I had my last GU, I wanted a VDO temp sender in the sump. I got an engineering shop to punch a hole in the back of the sump, as low as possible and not far from the sump plug (I checked there was nothing there with a bit of bent wire when I changed my oil, just to be sure I wasn't going to cause some grief.)

The engineer used a big centre punch to make the hole and then braised-on a steel nut which I had provided to him, with the correct thread to take the VDO sender unit.

I can't see why you couldn't do the same thing for the return line.

Having said that, I am also in favour of the idea of returning the oil via the rocker cover..... you can actually get (or make) up an alternative oil filler cap which has a swivel coupling that the return line is clamped on to. That way you don't even need to drill a hole in the rocker cover.

Hi Al
I fitted a Frantz oil filter to my 4X and it comes with a punch for puting a hole in the sump and a very coarse hollow fitting which screws into the sump for the oil return,no leaks and the filter works a treat. Cheers Snake. (not an ad for Frantz just a happy customer)
