Help... Knocking noise.. any thoughts advice welcom


IDO

Recommended Posts

Had a bit of a knocking/tapping noise last time I used the car a couple of weeks back, Its due for a mot and service so I didn't use it until today when taking it to the garage.

I've dropped it off this morning and the noise was worse.. the garage is going to have a look at it and get back to me, I have a quick look under the lid and couldn't seem to see anything wrong I am thinking it could be the bottom end/crank?

anyone had anything like this?

Expecting a call from the garage sometime today/tomorrow when they get to have a good look, also expecting them to say they have to have the block out to investigate..

 

My wallet is worried?!?!?

 

Anyone with previous on this kind of problem..

 

ta in advance...

Ian

Everyone on here will be just guessing as to what the noise could be, lots more info required or even

a video would be good.

 

Is it coming from the engine ? does the noise speed up and slow down as you rev the engine, does the

noise only happen when the cars moving etc etc

Thanks for reply Dnk.

Hi, Yeah i know people will just be guessing.. suppose same as the garage until they pull the motor out..

just trying to get a heads up on the bad news.. (starts crying and planning on a begging meeting with the bank!)

Cant get a vid at the mo, as car is at the garage and I am in work...

 

Def coming from the engine and would say bottom end (cant get under the bugger to pin point due to body kit) yep speeds up and slows down with rev's even out of gear when static...

The garage should have a pretty good idea without pulling the engine out, it sounds like

its going to be either a mains shell or big end shell is on its way out if its the bottom end.

 

All the best with the bank manager

Thanks Dunk,

Thanks kinda what i was thinking but i am not to tec' minded with the inner parts of the motor..

 

If you know, whats the kind of work involved on sorting a shell? just hope it hasn't affected the crank as well?!?!?

If it is a shell then its got a good chance of there being damage to the crank and that'll be

an engine out job im afraid.

No oil on a shell can create a lot of heat which scraps the shell and softens the crank journal

so it could require a new crank along with a set of shells.

Starting to get worried about fixing cost now..

 

what with a new house and other stuff, going to have to think long and hard about the pennies!

If its going to be a lot you may see a "how much is it worth" thread soon... @rse...

 

Had the Supe for over 7 years and not had any problems apart from a clutch cable go..

 

Don't want to but cost dependent i may have to say good bye... cant think of not having the supra...Not to mention the fun times in it, plus all mods i've saved for and had done over the years.. (from stock na auto to TT 6sp, BPU, suspension, exhaust, kit, wheels..etc, etc)

 

off now to cry in the corner... sob,sob

Before you get too worried, if it is the bottom end, I'm sure the NA and TT blocks are the same. NA engines are cheap and sometimes even free.

 

If I'm wrong, I'm sorry.

I cant really tell how much the labour is as i dont live in the UK. In sweden a small shop might charge around £50/h and the bigger dubble that. One the other hand the cheaper place might not really have any real knowledge about Supra and the 2jz engine.

 

Sorry if i got you worried, buy imo it would suck to hoist the engine out just to see that its destoryed and the aswell have to pay upfront for a replacement engine aswell.

 

Its not that expressive if you do it your self as iam guessing alot of the money is from labour cost. Its not that hard really and this is a great club with lots of knowledge and information.

 

Good luck

Even if it was identical its still a fair old bill to pull it out and just fit a replacement engine

 

10 hrs labour to remove and fit the engine and thats before you start swapping any parts over

etc so theres £500 to start with

 

Wait and see what the garage find first and then take it from there.

NA blocks need the oil squirter area's spot facing and drilling and tapping. Both oil feeds for the turbos drilling and tapping and the oil drain hogging out in the sump (or you can use your sump). You should be able to swap the oil pump after pulling it apart and checking it for damage and making sure it's still within tolerances.

Thanks for the advice all, will see what the garage has to say. (fingers crossed)

Pretty skint at the moment due to the house needing me to bleed money, will get it fixed probably pretty much what ever happens (within reason), even if its to sell on to cover costs.

Pitty i dont have the space, time, tools or know-how to do it myself..

 

Hope its good news from the garage! the bloke is a ex toyota mechanic with a good rep' so i trust him to see me right.. He's the only other person who has worked on it other than paul @ Whifbitz (who is just that bit to far away when i dont want to travel in a car not at 100%)

Are there no members near you who may have the know how and equipment to give it a go? It seems to me a "I need your help" statement may save you a fair bit of cash if people are willing to lend a hand. You never know.......there are a lot of people on here as you know, with the knowledge and ability to do what needs doing. May be worth asking??????

I got the crank of a member for £80.. It doesn't matter if it's an NA or TT, their cranks are the same. The parts itself aren't to expensive but you unfortunately will have to pull the motor which will take about 10 hours of labour... I had a choice of getting a second hand TT motor or to rebuild mine. I went for rebuild so now atleast I know the motor is good.. The problem I saw with getting a second hand motor is that you dont know the condition and it could fail in a month or a year, who knows..

 

Good luck with your motor mate.. I hope it's something simple.

Just out of interest where did your tt engine come from and when was it fitted in your na ?

 

Paul @ whifbitz got the engine and refurb' rebuilt it (with all new bits, inc pumps etc) around 4 years back.. as said been running sweet as a nut until now..

Have you done many miles since it was done ? seems strange for a rebuilt 2jz to have issues like this especially as its only a bpu motor

is a good idea mate, but don't think there is anyone close that could help, plus cant really move the car much from the garage where it is incase i make things worse..

 

Also wouldn't mind the garage to find out for def what the problem is..

I definitely won’t drive it anywhere until you are sure it's not the big end. Rather be safe than sorry bud, you don’t want to cause more damage.. Let the garage do their analysis first.
