peteretep Posted December 3, 2015 Share Posted December 3, 2015 But it would kind of make sense, I saw a screw driver trick on YouTube to feel for play. I will try that Quote Link to comment Share on other sites More sharing options...
peteretep Posted December 5, 2015 Share Posted December 5, 2015 I have put a dti down the spark plug holes and turned the engine back and forth and there was zero play between each direction so I feel all bearings are sweet. I have also run engine with tappet cover off and could not find the noise up top anywhere using stethoscope. It may be that the headers being thin stainless transfer noise better but they are certainly where the noise can be heard best with stethoscope. Too bad it's all 4 that make pretty much the same sound 1 Quote Link to comment Share on other sites More sharing options...
cletus Posted December 5, 2015 Share Posted December 5, 2015 ive got one of those inspection cameras on a flexible stick, you might be able to poke that in the sump plug hole or breather to look for a broken piston skirt etc 1 Quote Link to comment Share on other sites More sharing options...

sentra Posted December 9, 2015 Share Posted December 9, 2015 how does thats efficency compare with a small modern variable turbo motor? Quote Link to comment Share on other sites More sharing options...
h4nd Posted December 9, 2015 Share Posted December 9, 2015 They say 226g/kWh, so 16MJ/kg, and diesel is ~48MJ/kg, so 16/48 gives ~33% total thermodynamic efficiency. At full throttle, a smaller turbodiesel gives ~39% (from memory), but them are weasel words, of course. Â From the interwebs: Gasoline engines are about 15%-25% efficiency. New cars are at the 25% end. Diesel engines are 30%-49% efficient. Diesel semi trucks are about 35%. Large multimegawatt diesel power plant engines are up to 49%. (See Wartsila engines). Â This may still be a useful engine, because it's part throttle efficiency may be better than gasoline / small turbo diesel, bu tI suspect it'd be in production if the advantages were that compelling. I'd heard Prius get a similar effect by only compressing part of the compression stroke (valve timing jiggery), but using the full expansion stroke. Easier to manufacture, (no odd sized pistons, bores, counterweights), just needs cam change. Quote Link to comment Share on other sites More sharing options...
Spencer Posted December 10, 2015 Share Posted December 10, 2015 I read about those for Le Mans cars in Race Car engineering. There is for sure efficiency to be had form that set-up, depends on the goals of the motor though. Quote Link to comment Share on other sites More sharing options...
SOHC Posted December 16, 2015 Share Posted December 16, 2015 Alternator wiring failed on the Volvo tonight this time the earth wire to the body broke and it stopped charging, its funny the first thing to stop working is the temperature gauge, I think that little fucker uses more amps than the headlights. 1 Quote Link to comment Share on other sites More sharing options...

I've been fucking around with the guages on the 2105 and found the temp gauge strains the engine at idle similar to turning the headlights on 1 Quote Link to comment Share on other sites More sharing options...
Sparkle Posted January 25, 2016 Share Posted January 25, 2016 hey, didnt think required its own thread, E21 didnt start yesterday, turned key, dash lights on, no tur rurrs. Rolled it outside and managed to jump start it with my piddly pencil thin jumper leads on Jo's car (usually don't do anything) Drove for approx an hour to wanganui, started first pop when we left. Drove to visit someone in feilding, nipped out to get some dinner and wouldn't start, so crash started it. Started first pop when we left feilding again later on in the night. Started no problem since then, and took battery into repco for them to do a test, still pulled up 12.5v and 516cca. Â I thought may be a starter problem rather than battery, but surely putting leads on the battery wouldn't help this? Â IDUNOMAN Quote Link to comment Share on other sites More sharing options...
Beaver Posted January 25, 2016 Share Posted January 25, 2016 Checked starter is getting 12v signal when trying to crank and no go? Could be bad earths making funny things happen and extra juice from jumper is helping. Quote Link to comment Share on other sites More sharing options...
Yowzer Posted January 25, 2016 Share Posted January 25, 2016 When it doesn't start, does it just click and nothing else? Dash lights dim or anything? Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted January 25, 2016 Share Posted January 25, 2016 Could be as simple as a loose spade on the little solenoid wire. Quote Link to comment Share on other sites More sharing options...
Mof Posted January 25, 2016 Share Posted January 25, 2016 Or loose/dirty battery terminal clamp Quote Link to comment Share on other sites More sharing options...
Rookie Posted January 25, 2016 Share Posted January 25, 2016 To me it sounds like worn brushes in the starter giving intermittent starting. Seeings you have had the battery checked my next option would be to take the starter to an auto sparky and get them to have a look at it.

Yowzer Posted January 25, 2016 Share Posted January 25, 2016 ^ My thoughts exactly Quote Link to comment Share on other sites More sharing options...
peteretep Posted January 25, 2016 Share Posted January 25, 2016 I'd check loose wires first. Otherwise can try hitting starter with a hammer next time it happens. If it gets better when you hit it then probably starter related. Hitting it only usually lasts a few goes before the magic of the hammer runs away 2 Quote Link to comment Share on other sites More sharing options...
kyteler Posted January 25, 2016 Share Posted January 25, 2016 Check your earths, etc. Though it is likely a bung starter could also be related to your higher comp now maybe the starter is drawing more current and isn't necessarily up to the task.

Spencer Posted January 25, 2016 Share Posted January 25, 2016 You have basically all the answers above haha. Report back. Quote Link to comment Share on other sites More sharing options...
Sparkle Posted January 25, 2016 Share Posted January 25, 2016 Cheers chaps. All earths and leads to starter etc have been cleaned and tight. Similar sort of problem after just got it going, was put down to a bad earth on engine, so that may have not been the case after all?
