NOW BEING UPDATED AS I GO>>>>>Transplant engine now knocking, help please

[DodgyRog]

Right I am on the car now

 

I have done a couple of new video's which I will put up as soon as they have uploaded

 

Cold start, was fine, absolutely no sign of any knocking, Oil light went out immediately

 

Once the engine had been run for a minute or so there is a very faint knocking noise coming back, nothing like last night, you can only just about hear it

 

Occasionally as I move the camera around you just about make it out if you have the volume up, I don't know if it me, but when I took the Oil Cap off it sounded slightly loader, but very slightly, could just be general increase of all internal engine noise though

 

Taken the top Cam Cover off as well, Cam Belt looks fine to from what I can see of it anyway, just letting everything cool down again and I will remove the belt, but as the noise isn't really there now I am not sure if it worth removing it, as there isn't really a noise to make disappear, would I be better off letting it run for a bit longer and seeing if the noise returns properly

 

 

Youtube is saying 35 minutes to upload, so don't sit here waiting lol

I am not trying to blame Paul, I took the risk, I knew that there was No Warranty

 

I understand the risk you took mate. Warranty is always a good idea on a 15year old engine tho. Like you say its not Paul's fault.

 

But its in the past now. So chin up and keep going.

 

It doesnt sound to me like its completely fbar'd. Like people have said just investigate one part at a time. Personally i would get the oil dropped and filter cut open. Go from there..

[mellonman]

should of done the belt first mate , the reason it may not be loud when cold is because of the expanding metal, rog this more and more sounds to me like a loose crank pulley, exactly what mine did, take the belt off and you can probably wobble the hole pulley by hand

As soon as it's cooled down I will take the belt off, the top rad pipe is to hot for me to get my arm down there at the moment

[mellonman]

i have always found it easier from under the car , with a 14mm spanner linked to another for leverage, anyway thats why you should of done the belt first

[DodgyRog]

Cold start video

No sign of the noise with the belt off, but no sign of loose pulleys either

 

Going to put the belt back on and see if the noise is there at all with the belt on, then get it hot again to see if I can get the noise back like last night, then try and get the belt off while it is still hot and making the noise

[ashbuster]

can you check your powersteering fluid mate. when mine was low it made a nocking noise, just something to rule out too

[mellonman]

rog could you just try the crank pully bolt for me with the correct size rachet hot or not it may tighten if not then i would rule that out.

 

i know the engine will turn but get it to the point with most resistance the give the rachet a nice wack with you hand and you will tell if the bolt moved or not,

 

as above are all oil levels correct?

[DodgyRog]

I tried the bolt, seems tight from what I can do with it turning the engine, if it was in gear, would it not turn the engine then

 

Powersteering fluid is fine

 

Engine is now sat running, with no sign of knocking

Drop the car in 4th Rog, then try the crank pulley bolt again. You'll need a BIG torque wrench as I believe it to be around 300Nm required.

[ashbuster]

and the nocking was after being driven last time?

[DodgyRog]

There's no way I can get the leverage need to 300ftlb but it certainly is lose lose

 

and still no knocking, think I might have to drive it round the block

Yeah, but not boosting hard, maybe a couple of light boost pulls, proberbly about 3 miles ish

[girth45]

Take it for a run , get it hot and see if it knocks, might be easier to find. If knocking re due your checks again.

[girth45]

Did you say crank bolt was loose.

[DodgyRog]

This is the 2nd video from earlier

The engine has been running for about 15 mins outside now and absolutely nothing knock wise

[Hammer]

I really hope you get this sorted Rog. It is a stunning car and after all the work that has gone into it you will be guttede to see somebody else sort it a driving it. Sorry I can't be of any help but I think my mechanical knowledge is about the same as yours but at least others will give you good advice and help when you need it. Good luck mate, it sounds like you are deserving of a break.

[DodgyRog]

Just had a very short drive, got .5 bar of boost, but no sign of the knocking at all

 

Tried the screw driver before going out and could hear a slight knock when holding it to the front of the cam covers or on the metal between the coilpacks

 

After the drive absolutely nothing at all

 

The only things I have done are

 

Remove the Belt and check the Bolt for the Crank Pulley

 

I have but the bung in my Exhaust as I don't want to annoy my neighbours, is there anyway the back pressure it causes could be stopping the knocking in some way, the bung is very restrictive

not sure on what to recommend as your next move re your current situation, but wanted to say that I'd be very careful with your earlier plan of running the hot engine without the aux belt. I know when cold it's not a problem to run the engine for a short time but it's at operating temperature i'm not sure of the window you have before you could possible cause heat related damage.

Yeah, I was not planning to literally run the engine

 

I was heating it up to get the knocking like last night, then remove the belt immediately and just fire it up for a few seconds to see if the knock was still there, but as the knock seems to have pretty much vanished, not sure what the hell to do now

[DodgyRog]

Engine is sat on Idle on the drive now and no signs of the knock

[girth45]

Good news, serious engine damage ie bearings don't come and go.

I know your right in principle, but I am really nervous to drive it, obviously I need to get the Turbo's sorted anyway, but without knowing the cause of the knocking it risky

 

Paul if you read this can you either post on here or Pm me, was the Crank Pulley already on the engine or did you use mine off the N/A, as I know I said to if the TT block one looked old, as mine was only a couple of years old

 

Just wandering if it just isn't tight enough and the bit of messing around I have done, has been enough to tighten it just enough to make the knock go away temporarily

[DodgyRog]

As it is running now

have a look at the crank pulley when its idling mate you should see if its not straight or moving ect..

i would be nervous too lol

could it have been something silly like something knocking on something? intercooler pipe? heatshield? small fan? cam cover? noticed its off now

 

edit

just watched the first video again and sounds internal and not something knocking outside

Crank Pulley seems fine, I filmed during the cold start video, although it wasn't knocking in that one

 

It wasn't anything you have listed and it was knocking very slight before I drove it and the Cam Cover was off at that point

 

If you back and listen again to the video in post 1 and then the on I have just posted, you wouldn't believe it was the same car
