    Re: The 5s down due to knocking help!!

    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..

    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.

    Re: The 5s down due to knocking help!!

    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

    Re: The 5s down due to knocking help!!

    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

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

    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.

    Re: The 5s down due to knocking help!!

    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

    Re: The 5s down due to knocking help!!

    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...

    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.

    ....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?

    Re: The 5s down due to knocking help!!

    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..

    Re: The 5s down due to knocking help!!

    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.

    Re: The 5s down due to knocking help!!

    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.

    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..

    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.

    Re: The 5s down due to knocking help!!

    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
