hi iv dropped a bolt in the turbo pulled the rag I step the early dam it I herd it go dowen I got a rare earth magnet on a coat hanger cold not get it down far enough same prob with the bore scope running out of ideas please help
Hi mate thort of that last night after I calmed dowen lol going to drop off the front pipe and try to carefully spin the fan to make sure first then try the vacuum still looking for other ideas thow Incas it doesn’t work trying not to remove engine lol
if your going to use a vacuum you may need to remove exhaust and stop the exhaust turbine from turning due to the airflow. rotation might cause damage if the impeller turns and rattles around on a bolt. you maybe able to hook up the vac and then gently rotate the exhaust turbine in an attempt to dislodge the bolt. going to need velocity to lift the bolt, maybe you can attach the magnet to a probe inside the vac hose so that bolt only need to move a little.
Hi mate isent the front turbine conected to the exhorts turbine have spoken to a fue people who work with turbos they have all sead remove the front pipe and turn the turbine c if it jams is this correct?
yes remove front pipe They are correct, they are on the same shaft that is why im saying to hold the exhaust wheel to stop both from turning. the vacuum could/should be able to move enough air to make the turbines (both) spin. id be a bit worried that if it started to spin and was catching or then jambed on the bolt it could damage the wheel. Hold the exhaust wheel, start up vacuum and then slowly turn exhaust by hand. this is all bit dangerous so gloves would be the first precaution. i think this is probably a 2 man job, one operating the vac the other operating the exhaust wheel. To lift a bolt the suction will need to be strong. Have a practice with a bolt on the floor first to see what i mean. you will need to be quit close. it will be a bit different inside the housing of the turbo but it will take a lot of suction. you may be able to put your hand over the intake to create a pulse/ surge when your hand is removed. you may be able to increase the suction of the vacuum by using a smaller diameter hose duct taped on to the suction hose. try some thing that actually fits down inside the turbo. test first to confirm this is actually creating more power buy playing with that bolt on the floor again. Going down to very small hose may not work. depends on vacuum. Some shop vacs move a large volume of air but generally don't create as much vacuum as so your household hoover. where about are you?
you maybe able to stop the turbine with just the intake removed which would save removing the exhaust. but you won't be able to put your hand over the intake and control the turbine at the same time. some vacuums blow, you may be able to blow ( or use a compressed air gun ) through intake and use magnet down the exit side.
Thanx for the info it helps a lot as it happens I have a Hoover lol so that’s my job tomorrow I have a air compressor here as well I’m in Melbourne m8
just be careful with that air compressor it could spin the impeller pretty quick . If you have a tap on your air compressor you could duct tape up the compressor hose (with no fittings on it) to the intake so its sealed. Then put vacuum on exit side. Start vacuum and then open tap on compressor to get the maximum velocity you can generate. This will empty the compressor pretty quick and it probably wouldn't keep up but your just after a high volume blast. If doing this though you would want to have the exhaust off to control the impeller. This could be dangerous to fingers id be using something like a block of wood to stall the exhaust wheel . You'll get it sooner or later just keep going and be careful you don't want to hurt yourself or the turbo.
Im in new Blue mountains so i can't come and help sorry. Ok last questions 1) are you sure a bolt fell in? it's going to take forever to extract a bolt if it isn't actually in there. 2) when rotating impeller can you hear or feel anything? your welcome not sure if i have been any real help. these are just ideas you or someone else may have other better or variations of these ideas which actually solve the problem. best of luck.
I’m dropping off the front pipe tomorrow to spin the fan I’m hopping it spins with no problem but I’m nerly 90% it in there iv done heeps of work on it all water pipes with blue silicone hoses after market radiator thurmo fan with the highest cmf I cold find all gaskets and seals brass washers I polished the plenum it took ages spent a lot of cash and time this is my first z32 I love it just wana drive it now lol it still needs a heater core left hand windscreen mould and left wiper panel but it’s getting there thank u for yore time it apreshiated
well if your not 100% sure its in there and no matter what you do you don't seem to be able to get it out and the intake wheel spins freely (indicating that it MAY not be in there after all) what are you going to do? i would be very worried about starting the engine. if the bolt is just sitting in there it will defiantly fly out once the turbo spools up and end up in the intercooler at best. worst case scenario is it damages the turbo, the intercooler and some of those damaged fragments enter 1 or more cylinders damaging the engine. which turbo is it? i haven't had a good look but it maybe possible to remove the passenger turbo with engine still in car. drivers side has the added problem of the steering column OTHER MEMBERS WILL HAVE A BETTER IDEA ON THIS THOUGH.
I’m also thinking of blowing air in and listening for a rattle through the front while iv got the pipe off I am verry well equipped with tools I just haven’t had this problem before it’s stumped me I’m fully aware of the wot happens if I start it I’m hoping I can hear it rattle it is the left iv given my self a huge job any ideas is good at the moment u have given me sum ideas I think may work thank u if u or any one else has ideas I’d love it hear them thank u
Might also put the magnet as far in as I can while blowing it from underneath c if that works and maybe do the same when useing the vac and blowing it through the front it may come up enuf to catch on the magnet
Hi mate after all that pulled the front pipes fans spin freely used the air compressor blowing air in while holding fan as well no rattling the turbo God’s are on my side thanks for yore help I was stuck for ideas
might be worth blowing air in outlet in case bolt just hasn't fallen all the way into impeller. need to be as sure as can be.
