300tdi Any Ideas???

Hi CharlesY,
I have always been told to use Vaseline on car battery terminals, and have used it on eathing points also as it's a conductive grease. Of course Coppaslip has copper in it, but is the grease conductive?

Presumably there's fancy purpose made grease to put on these, but what is the right stuff?

And of course I'm now waiting for all the Vaseline jokes...

There is a conducting grease available but the only time I ever had any was when I could swipe some from the leccy board guys. Vaseline does the job fine, but is no better than any other grease. Copper grease seems to work for me, and is better than the others because it handles corrosion problems better.

As to Vaseline being electrically conductive .... NOT.

I just tested some Vaseline this minute.
With a gap of under half a millimeter between the probes and my meter set on the 20 meg-ohms scale, the meter still could not make any reading and called it open circuit. Vaseline seems to be a strong di-electric.

Copper grease is definitely better that that.

Yu is rite- vaseline is NOT conductive- but it does have a higher melting poi t than most greases and is more likely to stay put in a hot? Summer.

My N/A once ingested a piece of metal that had flaked away from the original filter housing. Needed a new piston and the head is still slightly pitted. I'll get in touch with them and tell them that I'll take it to bits and try and do the job for a good reasonable rate

Well on connections you expect to handle 300 amps plus then I would have thought a conductive antioxidant a good idea.

I'll have a look to see what's out there tomorrow.

If yer on about connections.. just make sure it's clean, clampit up and stick copper grease/ vaseline over the top of it and that will hopefully seal it from any ****e gettin' in there.

yes 300 tdis do turn slowly and you will find that even a jump off a large petrol will struggle to start it ie 2.6 skyline couldnt start my old disco however 2.5 ldv convoy will start it on tickover

bollocks they do mine turns over faster than anything ive driven before, and starts EVERY TIME with no glow plugs at all.

a 2.6 skyline couldn't start it? ****inhell ive jumped mine off a 1.1 metro battery before now...

Sorry though, im jus in a bad mood tonight.

A lot of 300tdi's do turn over really slowly, take my Disco, it's always been sluggish on turn over before and after the new starter was put in, checked all the cabling everything.

Then my 90's 300 spins over like a jet.
