Yeah the car just started before, i managed to move it somewhere more practical, it took me awhile to get it going though, and its blowing heaps of white smoke - will it be okay to drive for a 2hour trip as ill need to get it hoome asap.

I would'nt want to drive it you might do more damage.

take it extremely slowly driving home. dont rev over 2k. just dont let the turbo come on to boost. its gonna be a long drive home for you.

but honestly, get a cab home or get the car towed. atleast you'll minimise any damage chances.

cheers mate, ill get the car trailered back instead of driving it down, can you confirm this would definitely be the problem, i had a go sarting it again, and just as the engine cranks - i hear a bad clunk noise (seems as though its coming form the rocker cover/fuel rail area)for a quick second and then its gone, car starts and white smoke.....im not taking any chances...could it be the head gasket?

Head gasket "immoveable object" generally, difficult to make it rattle, maybe dropped exhaust valve or part of? Maybe time to immobilise ignition/startup & get stethescope out. Trust it not be serious.

Hey guys, got car trailered back, car runs but really bad, and im not starting it again!, coolant was fully drained and was spitting out the exhaust (smell was very acidic). In closer inspection the oil has water mixed in with it - looks like a buggered headgasket dont you think? is this going to be a big problem>?

yup, sounds VERY much like a BHG.

its a largeish job, and the head will prob require machining. so possibly consider doing some performance mods at the same time to make the labor bill worth it.

you should probably do a compression test - blown turbo doesn't normally stop the motor from starting - but low compression will.

and definately dont drive it 2 hours even if it is a blown turbo

White smoke & no coolant = blown headgasket

Who knows how long it was like this, but I've got money on your oil looking like milk. Hopefully the noise you heard wasn't un-lubricated metal smacking around in there.

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      sold listed as a Tomei LSD 1.5 Way For 1998+ Nissan Skyline ER34 25GT RB25DE w/Open R200 https://www.ebay.com/itm/174006114594?campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=&mkrid=711-53200-19255-0&loc_physical_ms=108689&loc_interest_ms=&campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=71883f2ccc571356e0a757bc7adfdde2&mkrid=710-53481-19255-0&loc_physical_ms=108689&loc_interest_ms= it went in like butter all gears, alignment, back lash etc, rotation and clearances correct, and if rolling all rotates smooth and free when coasting down road , clutch in or out over 10 mph smooth... its the binding, clunking and jerking from a stop that is most concerning, also seems like its going to tear the tires off in 10 miles of normal road driving.

      What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.

      Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
