Loud Bang 4agze HELP PLEASE

[Charged1]

Help , was driving up the road today and the motor went Bang ! and then all this smoke came out of the exhaust , after that its making this loud as noise , have I blown a cyinder or something , would it be safe to drive to a garage or better to get towed , any ideas ?

[smokabitabud]

haha thats what happened to my prelude after i got my new car and decided to fuk it. mine threw a leg probly summin similar. check ur oil lvl and c if theres ne holes in the bottom of the motor

[Charged1]

Oil full , no holes , Im guessing it piston , cylinder or head gasket ? but im no expert ???

get it towed to a mechanic who specialises in bangs.

[Dell'Orto]

What kind of noise? What colour smoke?

[deaf_rattle]

where abouts in aucks are you?
I may be able to come have a look if you like

(if out west)

[Fuct Munkey]

my FXGT did that when i was push starting it, i have blown out one of the rear mufflers. might be the same thing. it had been repaired before, and i blew a hole in the side of it. but thats what ya get for having a factory exhaust thats done 404xxxkm. nice carbon build up to ignite.

[Charged1]

Nah mate im not out west , up at Paremoremo , just out from Albany , but thanks anyway , question if it sounds like its banging the block is that a piston ?

[Charged1]

Sounds like something internal hitting , was a cloud of white smoke

[Dell'Orto]

If its a constant deep knocking noise, then it'll probably be a big end bearing gone up the $&#$%.

[Charged1]

Yeah mate thats the noise , is this a major then , is the motor stuffed ?

[Dr-X]

get it towed to a mechanic who specialises in bangs.

LOL That made me laugh so hard

Sounds like a big end.

[Dell'Orto]

Yeah mate thats the noise , is this a major then , is the motor stuffed ?

Yep, its pretty major, and yup, in that guise, that motor is toast. Get it towed to a mechanic, and they can fit new big end bearings and regrind the crank, or alternatively fit a 2nd hand engine.
With the availability of 4AGZE's being the way it, its probably gonna be easier to rebuild it
Dont drive it anymore thats for sure, or you will have a ventilated block.

[Charged1]

Thanks for your help mate , sounds like it may be cheaper just to put a 20v in , are there any other motors that you know may be able be put in without too many major mods haven to be done , cheers

rebuild+turbo

[Charged1]

Hi how many grand do you think it would cost to do a rebuild and turbo

[deaf_rattle]

$1k for all the work, if you can assemble, clean and pull apart yourself

probably need a crank grind and polish, new bearings to suit and may have to get your conrods resized.

probably need a bore hone as well

might as well do rings etc while you are at it

[levin_it_large]

depends how much time u got, i take it its a daily driver so u don't want 2 b away with it for long?
finding the parts unless u in the trade is the hardest part. if u have the skills 2 do it obviously it will be cheaper if u want a garage 2 do it it'll be a few g's!

[craigt]

I spent over 2k on my last freshenup on my gtz.
That was with bits at cost, but also included guides, 5 angle valve job,
waterpump all belts and tensioners, supercharger oil etc, the list goes on.
Mr Autosure picked up most of the bill!!!!

Look around for a second hand motor. If you can find a guy who imports them he sells a motor for about 1200-1400 dollars.

By the sounds of it you have run a big end bearing and if its not too bad then will cost pritty close to 1k anyways if you canot do any mechanical work your self.

Get a second hand motor then take your time and re build that one and make it strong for turbo an lots of boost.
