With the head off its much easier to attend to the timing chain. You want to be really sure what caused this having just done the water pump. With the timing cover off it may be more obvious. You need to be sure that the jackshaft spins freely and you can feel the pump turning nicely. Any impact marks on the pistons? They are often numbered and also graded in letters with F being the closest to bore tolerance IIRC. Jonners |

I've managed too turn the engine and the water pump seems ok , I take it I'll have to remove the crank pulley to take the timing cover off ?. I didn't see any marks on the pistons I'll check again tomorrow. The pistons have front + 20 written on them. Is it possible that the chain has jumped a cog ? The timing side of things isn't my strong point so I didn't turn the engine too far but it seems ok Thanks for the help Jon it's much appreciated  Tom Any idea what the nut on the manifold is |

Today I partly removed the timing chain cover ( I say partly because I haven't got a socket big enough to remove the pulley wheel yet) just to see if their was anything visibly wrong and I noticed that the chain tensioner was quite extended so much so that the chain was coming back on itself. So I think I may need a new chain as this looks stretched to much Attachment: IMG_0370.JPG [ 34.1 KiB | Viewed 2731 times ] Apologies for the picture it's the best I could do |

No that's misleading....with the head off you dont have the chain in the correct position and if you turn the engine the tensioner will ratchett out. Its not broken....take it all off properly and get that pulley off then you can reassemble and know its done right. The pad is still on the tensioner and doesnt look too bad, but you will see more when its all off.... You still want a diagnosis as to why it locked up.... Can you turn the cam over reasonably easilly - it will sort of jump as the cams press on valve springs? Sorry to say but getting the crank pulley off is going to be a mare with no starter and only the gearbox to hold it now. Lock the flywheel ring gear with a suitable wedge in the starter hole. Dont forget the bolts through the sump that go in the base of the timing cover. Jonners |

Looking through your posts, it seems your problems started after doing the water pump. Have you taken inventory of all excess bolts you may have (and small spanners and tools), it is very easy to drop something into the inlet orifices, whilst all is open have a good look, I find pictures show up more detail than the naked eye. |

Thanks for the reply guys. Yes I've done it the wrong way round really. I got a breaker bar on order and a 38 mm socket so now the lighter nights are here I'll probably have a go one night this week.. Yes Mahesh I can be a bit of a messy worker but I made sure all bolts were put in containers with where they go written on it. I haven't turned the cam on the head yet Jon been out all day today so will try that later in the week too again thanks for the advice it's most welcome

For those of you that have been reading my little resto thread , I have now discovered what made my engine come to an abrupt stop after attempting a compression test. It was this Attachment: IMG_0639.JPG [ 20.46 KiB | Viewed 2661 times ]  All I can think of it stuck too the rocker cover and dropped down onto the crank sprocket At least it's nothing terminal. I also discovered that whoever worked on the engine before used a alloy cylinder head nut which has stripped it's thread so I'll have to get a new nut |

Whenever a car new to you is worked on, it's always a voyage of discovery punctuated by islands of why the f$ck did they do that?! |

I'm glad you found the cause, otherwise it's a constant nag. (I'm not going to crack the joke)my missus might read it). |

I've had a few of those thoughts today ,like why plaster everything in sealant when a gasket set isn't going to break the bank ,,no wonder it's got more oil on the outside than in it  Quote: I'm glad you found the cause, otherwise it's a
So am I Mahesh to be honest it was a relief to actually spot it ..it was halfway round the crank sprocket and only just visible.

Well now you have the added benenfit of doing the timing chain right as well.... And do please read up on doing this before you attempt it....  Its a hairy old job and easy to get wrong. Put the head back onfirst after decoking and ask lots of questions... Jonners |

Hi all  haven't done too much lately so here's a it of an update.After doing the timing chain and valve timing which went better than I thought it was going to do.I set about doing the ignition timing and after a bit of prompting from incadolly I got the car to fire up but it wouldn't run at all well ,after a bit of a search I decided too strip the carbs, the mounts didn't look too great  and I think I was right here's a pic

Thanks for the reply Jon, the thing is when looking to see what I needed to rebuild the carbs I typed in the numbers on the float chambers AUD545 and apparently these carbs were made only between 1973/74 so a previous owner has changed them. So are they still the right jets for those carbs?Some dont like them but I quite do.... Jonners Tom |
