Hi All Just wondering if anyone out there has fitted up a by-pass oil filter on a 2003 4.2Tdi GU I know where to pick the supply line up with a T piece out of the oil pressure sender. Where to place the drain line back into the motor is the problem, the only place I see is the turbo drain pipe, which means pulling it off and bronzing a fitting onto the drain, not unless someone has done something different. Any ideas would be welcome
Cheers Steve

G'day Steve,
I'm currently in the process of fitting a Frantz filter to my '99 4.2TD...
If you have a look on the side of
the block just behind & just below the rear of the alternator, you'll see a plug ( 3/8" PT I think?? ) which I believe gives access to the oil return gallery... Pretty sure this was for the oil return from the alt.-mounted vac. pump on earlier 4.2's...
I'm sure (I hope) someone will correct me if I'm wrong...
Regards, Ed. C.

Yep, just been & checked.. The 3/8" (BSPT, I presume) threaded hole mentioned above does indeed access the oil return gallery..
ATTN. Steve >> The thread on the oil pressure sender unit on the Nissan 4.2 is 1/8" BSPT (28 TPI).. The fittings supplied with the Frantz filter are 1/8 NPT (27 TPI).. They are close, but um, NO CIGAR!! If you attempt to join BSPT to NPT, then the threads will be, how you say, FUBAR!!!
Make sure you have the appropriate T-piece !!! (and of course, the fitting for
the block)...
(Just thought I'd bettermention it)....
As
well as the alternative mentioned by Stan (below) for the oil return, Frantz can also supply a swivel fitting which goes into the oil filler cap, so you have a few choices...

Yep, agree with Ed on that.
I have been using Frantz on oil AND fuel on my '90 GQ TD42 since new- and my sons '81 diesel Gemini since new. Great results- both motors are virtually as good as new with greatly extended oil changes.
The old Gemini is heading nudging 400,000klms with never a spanner having touched the engine itself- can't of course say the same for radiator, alternator, and brakes. But the clutch is original!
IMHO bypass filtering is
well worth the effort.... though once fitted it is less effort as the extended oil changes save a lot of work... only takes a few minutes to service the bypass element.
And for those who go down the Frantz route.... I modify
mine by putting a small screw in the top of the can which allows the oil to drain out faster before servicing. Makes life a lot easier and less messy! Unscrew the screw an hour or so before servicing.... (leave the car keys with the filter to avoid embarrasment) then refit the screw just before removing the filter can to replace the element. -easy!
Cheers
