After spending alot of time looking about for parts for my LS400 that wouldnt cost the earth I contacted an unlikly source to see what he could do.
I'm pleased with the price given that I didnt have to wait for international delivry or pay import charges

I've read the instructions for changing the plugs / leads but does anyone have any other tips that may come in handy?

I've also found brake parts at a reasonable price from www.buypartsby.com

My car was cheap I have to say - it hadnt been looked after very well by the last owner so apart from the service I'm starting on shortly it also needs some of the bushes replacing (superflex are a good source I hear) new disks and probably the gearbox fluid replaced. It will get there in the end!

Hi,
I guess you are using the Lexls tutorial for the plug/lead change. I did mine a few weeks ago and a couple of points not mentioned are the coil to distributor leads are clipped on to the coil and you have to depress the clip to remove the lead ( do the top coil 1st so you know how to do it as the other is mounted lower down the engine) and the lower coil lead passes through a rubber grommit in the engine cover so beware when removing/refitting.
If you are using OEM leads they will fit into the original wire holders but make a note of the routing for each one.
If the old leads are original they are numbered and date stamped and may also have additional plastic spiral wrap at the bend points this proved impossible to remove as it was so brittle with age so my new leads went on without it.
You should have some dielectric grease in the lead pack make sure you use it.
Ther plugs are deeply resessed in the head and you will need an extension on the plug socket to reach them also hand start the plugs as the head is alloy.
Good luck.

Many thanks for the tips - the leads are oem size - I'm not after performance gains on this car (yet), just getting it on new stock parts. I have a project car already and need this one to be tame and relyable.
