Bones28 Posted September 19, 2016 Posted September 19, 2016 Hi when you put an earth to the pump can you hear it work straight away or only when the key is turned. Quote 2002 Porsche C2 996 3.6 1991 Nissan 300zx TT Project 1995 Nissan 300zx TT Crashed 🥲 1997 Jaguar XK8 Scraped ☹️

Bones28 Posted September 19, 2016 Posted September 19, 2016 You can earth it temporarily till you find the bad earth connection. Quote 2002 Porsche C2 996 3.6 1991 Nissan 300zx TT Project 1995 Nissan 300zx TT Crashed 🥲 1997 Jaguar XK8 Scraped ☹️

300zx aly Posted September 19, 2016 Author Posted September 19, 2016 bit like a crunching noise didn't have it running for too long will check tomorrow just wanted to get heads up things to expect or look out for Quote
Alic Posted September 19, 2016 Posted September 19, 2016 bit like a crunching noise didn't have it running for too long will check tomorrow just wanted to get heads up things to expect or look out for If I'm honest I wouldn't run it until you jack it up, see where the leak is and get some oil back in. Running it with low/no oil will shred the guts out of it. Quote
Stephen Posted September 19, 2016 Posted September 19, 2016 Repair leak, change oil try again. Don't go driving it about with no oil. Quote
Guest dan300zx Posted September 19, 2016 Posted September 19, 2016 leaks .. input shaft seal/ gasket out put shaft seal cracks or maybe it had a loop on on were the oil cooler was if its looped it could have came off and this will make all the oil come out. Quote

And coolant is still clean? Quote
300zx aly Posted September 21, 2016 Author Posted September 21, 2016 light white smoke didn't check the coolant Quote
Stephen Posted September 21, 2016 Posted September 21, 2016 ok guys found out what the leak was it was oil cooler adaptor come lose fix that back up fill the car with oil and now its running fine with one little issue am getting white smoke from the engine driver side back bottom don't now what it is Is it not the residual oil from where your oil cooled adapter was leaking? That would be about the right area. Quote
300zx aly Posted September 21, 2016 Author Posted September 21, 2016 that's what am thinking lets hope it is just that I did take it around the block it drove fine all the gauges seem normal Quote
Alic Posted September 21, 2016 Posted September 21, 2016 that's what am thinking lets hope it is just that I did take it around the block it drove fine all the gauges seem normal Personally I would give it a good run to clean any residue out of the system. Then if problem still occurs then start checking further things. Quote
300zx aly Posted September 21, 2016 Author Posted September 21, 2016 the smoke come through the bonnet near the break master cylinder Quote
Alic Posted September 21, 2016 Posted September 21, 2016 (edited) the smoke come through the bonnet near the break master cylinder Was this straight after you started the engine or once you'd been driving. If it only happened whenthe engine was warm it might just be oil residue evaporating off as Stephen said Edited September 21, 2016 by Alic Quote
Stephen Posted September 21, 2016 Posted September 21, 2016 Why not do a proper job and get under there, clean and inspect. You won't get it all off particularly if your exhaust is old and rusty. But your going to reduce it. A little oil goes a long way, smoke wise. Quote
