The 5s down due to knocking help!!

[Nottswoody]

I'm going to check a few things out first take one bit off at a time then the clutch inspection plate just I was thinking what If something fell in there? Look at everything before taking the engine to bits it just Dosnt seem right that the engine would be fine one minute and not the next. Sadly it's all down to money now I thought spending all the money on the extras was the way to go and then the knocking happend.. I hope it's something simple. Iv booked next week off. I know the mrs won't be happy but tough. so if I haven't found out by monday I will take it apart and learn myself. Got nothing to lose..

[andybond]

Dude ,

you are playing exactly the same game as I have just played. Its the game of doubt. You dont want to believe your engine is FUBAR so you look for other things , has something gone down the carb that shouldnt? Is something in the bellhousing? Has the clutch shat its biscuits and is now rattling ?

Ill place a big big bet on it ( a packet of* CHOCOLATE hobnobs ) its the bottom end and nothing else.

[Nottswoody]

So just take it all out then and strip it?

[Nottswoody]

So I just rang cgb and they priced a bottom end £200 they won't sell full engine as can not gâteau what head gaskets in it. Makes sense really but from what you guys say it's about £200 to build my own.. So Iv got enough tools to get the engine in & out what would I need as in special tools? I could borrow a T wrench from my mate.. Cheers guys looking forward to building it now. so I get the head bolts from RToC shop.. Weres best for HD gasket? Remember I want the big boost this time.. If any one has a list that would be great

[Markey Mark (BD)]

Speak to Mike @ GT Turbo Spares, he'll sort you out with all the bits you need

[R5TURBORON]

The new wheels for a while I need the excercise any way

[Nottswoody]

Hi guys help us out I can't find it on here.. How to strip the bottom end.. Cheers

[R5TURBORON]

You looked in your hanyes manual mate

[Nottswoody]

Doh what I should of said was better pics than the bible

[R5TURBORON]

Will see what I can find

[Tony Walker]

Depends how much your stripping. Engine mount front drivers off, lift engine up take sump off(will just about come off) Then id personally just try big ends, undo one cap at a time, being carefull to take the cap off and keep it in the same direction(dont turn it around they are snapped so that they will only tighten one way round, it should be pretty obvious when pushing the cap on to the rod which way round it goes, itll either mate nicely or not) with the piston at the bottom of its throw is easiest, then push piston/rod upwards remove bearing from rod and cap noting which way round the bearing tags are positioned replace the new bearing making sure surfaces are clean, check the big end crank journals if there not scored put some oil on the cap/rod/crank and pull the piston/rod back down on to the crank journal. place cap back on (in the correct direction, it should fit together nicely) new rod nuts should be used (i have personally re-used mine) Tighten the nuts evenly to its first torque stage(around 20nm thats a geuss so check that) then tighten to second stage( around 45nm i think,again check that) then check engine turns over freely, and on to the next cylinder. Wont take you long

[Nottswoody]

The plot thickens looking around the engine bay and a but is missing of the Turbo to exchaust.. Hmmm could it of Fallen into the gearbox?

Not unless you have a big hole in the top of your gearbox?

[Nottswoody]

I was thinking the TDC part plus I don't have the cover on the rubber type.. Clutching at straws I no.

[Big Steve - Raider]

I was thinking the TDC part plus I don't have the cover on the rubber type.. Clutching at straws I no.

Both the TDC part and the rubber jonny give access to the clutch mechanism. If the clutch is working (relatively) fine, then it shouldn't be that.

If there's a exhaust blow though you need to sort that, exhaust blows can make dodgy sounds.

[Nottswoody]

Clutch is spot on and brand new.. It's a definat metalick loud noise check it out a bit further up this tread.. As I say I know I'm clutching at straws.. I can't get to strip the car till next week but im ready for the worst..

[Nottswoody]

Quick update good news a garage near me has been doing the mrs car mot and Iv had some work done on her car as well told all my friends to go there as he was very good and well priced.. So I got chatting to him about the 5 and what has happend.. Told him what I planned to do ie rebuild the engine.. He had a couple a grands work sent to him through me and said he was gratefull.. So he only said get my engine out strip everything off the block and bring it to him. He then said his lads stand about too much and as long as I leave it with him for a week they will strip it send it of to be rebuilt and while it's there have the flywheel lightendand balenced.. No charge for the stripping and rebuild just the work thy needs doing at the engineers.. Top banana!!! Il have a bit a that thank you.. Much happier. So the plan is Wednesday engine back out and strip it down.. . much happier today

[Nottswoody]

So next question is if I have the flywheel lightend an balanced will I need to change my clutch in any way as its only done about 700 miles since new.. Also never done this before

[Tony Walker]

nope.

[Nottswoody]

[Nottswoody]

There's an engine on eBay for £300 is it anyone on here?

[andybond]

looks like this chaps .

Cross ref on ebay

[Nottswoody]

So with the engine out I'm going to lose and move a few pipes and tidy the bay up. How a what can I remove keep and move??

[Nottswoody]

Been looking at cams.. What is the standard cam good upto? I have the t25 now do I need to start looking at the 270 or 280 piper? I aim to run a good 18-20psi.. Has anyone got all I need used?? Or should I buy new? Figured if I'm going to do this Im going to do this right.. Must be loads of heads out there?

[Nottswoody]

Well the big day is here.. Got some time off work so after a week of just leaving her in the garage it's full investigation day.. See what the knocking is get her up on axel stands and get under her. If I still can't pin point the knocking tomorrow I'm taking the engine out and full strip down will happen.. Let's hope it's not too much damage.. Fingers crossed I will get to this years ND.. Let's see what we find...

[Nottswoody]

It really sounds top end knocking could I of dropped a valve? Everything feels ok been under the car and it Definatley sounds top end.. Any advice? Or should I just whip it off?

You're talking about engine rebuilds, yet you don't actually know what the issue is yet....get it diagnosed properly and stop grabbing at straws.

Never take any 'noise' as a given on these old French sheds until you've proof in front of you.

[DaveL485]

New poster! (less than 10 posts)

....OK, to give a better idea:

Does the frequency of the noise increase with engine speed? (ie, Not Road speed)
Does it change depending on whether the engine is accelerating or decelerating?
Does the engine miss at all, or is it consistently firing on 4 as it should?

What is your mechanical ability? Can you get the sump off and remove a big end cap to check the bearing? Do you own a torque wrench to refit it properly?

[Nottswoody]

Cheers for the reply.. Soon as I started it the car was silent running lumpy but running then two seconds later a load rattling from the top end.. Had the plugs out and nearest the turbo looks like its dinted inside been losing water only a bit there is smeg in there so I'm in the process of taking the head off now.. Time to stop pissing around and find out what it is.. Either way it needs looking at as its a terrible load knocking not a small noise..

[LYNCHSTAR]

bloody hell paul get head off because there is a gasket fault and take sump off take big end bearings off and pull pistons out the top and check the shells and check that the cranks not scorn after hearing it that day it sounded just like my old 5 and that was the problem if your not sure just strip it down like i told you and ill come take a look and if the crank looks ok ill put pistons back in for ya. if cranks scorn id be looking for a new bottom end or a complete engine.

[Nottswoody]

It wasn't a bearing at all it was a washer in number 1 piston like I thought all along look its ruined my head and the piston top. So I think I will just by a new engine and be done.

Gutted...

[R5TURBORON]

Gutted mate hopefully be sorted soon

[Brigsy]

That looks like its been detting its nads off tbh mate. The knocking will have been off the piston

[R5TURBORON]

I went and looked he found a battered washer on top of the piston

[adscan]

how would a washer get into the piston?

[GTphil]

must have been dropped in through the spark plug hole or just ended up there as a stray the last time the head was off

[Nottswoody]

Taking the head to see if it can be saved it measured at 73.2 so getting close anyway.. I will make ND What's a good price for head work? On the car that is

[Nottswoody]

Well good news getting the head sorted today skimmed and machined for a cracking price. He said the hg was gone anyway so looks like I would have had todo this anyway.. What I need is a part number for a 1.8mm head gasket as I want this built today!!! My local factor says he can get it today if orders before 2pm.. Cheers guys..

[Brigsy]

It might be 1.9mm mate thinking about it?! Cant actually remember 100%. You need the corteco mellior gasket or the payen gasket, both work fine. Any half decent motor factors should be able to get you the payen, gsf used to do the mellior. Dont buy the cheap gaskets unless you want to replace it again soon.

[Nottswoody]

Oooooh no no no. No more doing it on the cheap.. I will mail mike...

[Nottswoody]

Never knew there was a gsf in Nottingham I got the cortego? For £26 pick it up tomorrow. Cooking on gas:-)

[Brigsy]

Might be worth chcking the exhaust wheel for damage on the turbo whilst its apart matey the remainders of the metal will have went thru it

[Nottswoody]

Been through all parts and thankfully I took my time home and didnt bring the turbo in. Stripped everything now and all looks ok thankfully.. Picking up new gaskets in the morning and will rebuild tomorrow now.. Just going to clean for the rest of the day while waiting for the head back but at last I can see the light

[R5TURBORON]

Nice mate will try and pop over after work tomorrow

[Nottswoody]

What a service took it the 4hrs later done..

Nottingham area guys i can't praise this guy enough and he welcomes members business..

This is the best he could do with how bad the head was but all tested and says its fine.

Nice should be running at the weekend :-)

[adscan]

did he do the bottom end as well? i remember seeing in your pics that your piston was toast. what about the liner? was that replaced?

[Nottswoody]

The liner is luckily untouched and no scoring and the top of the piston was just slightly dented the head took the most damage.. I didn't lose any compression car drove fine it was just noise. Everything else checks out fine so far.. No more bits nothing in the oil everythings tight no movement.. Hopefully its sorted just waiting for bolts to arrive now then back on the road.. They are tough little engines but bits in the engine will never have a happy ending.. Such a shame too as the engine may of looked dirty but was very quiet and pulled very well.. Hope this hasn't changed that or I'm taking it of the road and going down the 172 route

[Nottswoody]

What size are the bolts on the blanking plate to the head? M6?
