2 the oil filter is being knocked by the front axle just in normal road use any one else had this problem how can i get round it before i smash it off

For the gauge I would simply replace it with a Racetech version. For the oil filter you need a remote oil filter kit. A grown up should be along shortly to point you in the right direction.

Oil filter you have several options of varying price/bling:

1) Think Automotive PC1 replacement pump cover and RFH remote filter head - costs around £100 but replaces the oil pump base and knocks a massive amount off the bottom of the engine. As long as yours isn't a 4.2 or 4.6 it will fit fine (ask me how I know it won't fit a cross-bolted block <_< )

2) Spin-on adapter goes on in place of the original filter, knocks a couple of inches off the length of the filter, you may want to measure carefully before going for this although it's about £20-30 cheaper.

Remote filter head you will need with either option, there are different directions of ports available:

All from Think Automotive.

When you measure the axle travel, pretend the bump-stop isn't there - assume the axle could go all the way up and clonk the chassis, that way you'll *know* that you have enough clearance.

Dirk....

Does your engine have an oil cooler ?

If so, you may want to consider removing it.

My 3.9 came with oil cooler and the oil filter was lower down as a consequence of the extra pipework.

Once removed it raised hte oild filter back to it's expected height and cleared all the internals of the lower engine bay...

(Mine was 3.5 V8 formerly so issues may be different...)

If you have an oil cooler I'd think about removing the takeoff plate for it and plumbing it in-line with the remote filter, an oil cooler makes a bigger difference to engine cooling than you might think and is worth keeping if you've got one IMHO.
