Pete Lewis Posted December 3, 2020 Report Share Posted December 3, 2020 can you get her running and record the racket ?? do check a rockers not in contact with the cover and rockers/ valve spring or pushrod are not a simpler culprit Pete Link to comment Share on other sites More sharing options...
Bordfunker Posted December 3, 2020 Report Share Posted December 3, 2020 Conor, really sorry to hear that, but as Pete says it may be something simple and easy to fix. Heres hoping it is. Karl 1 Link to comment Share on other sites More sharing options...
Conor L Posted December 3, 2020 Author Report Share Posted December 3, 2020 It certainly is @Anglefire real loss in motivation. I have got tomorrow off work so I'll get it fired up and record a video @Pete Lewis I've got my fingers crossed its something as simple as the rockers hitting the cover but if I'm honest it did sound louder at the bottom than the top.

Conor L Posted December 3, 2020 Author Report Share Posted December 3, 2020 I seem to remember the engine had work done prior to my ownership that I discovered when I pulled it apart back in 2018. From memory it had been bored out to +20 and had a crank grind +40 on the big ends and +10 on the mains. Could never work out why considering the car is only showing 66k miles and 9 years of service before being parked up. Engine is the original confirmed by a heritage certificate I had for Christmas last year. Maybe its had a similar issue in its past? Certainly fuel for thought.

poppyman Posted December 3, 2020 Report Share Posted December 3, 2020 Worth checking everything first Conor, does the noise get worse with more rev's? Also does it still have noise when you put your foot on the clutch? Tony. Link to comment Share on other sites More sharing options...

alan.gilbert_6384 Posted December 4, 2020 Report Share Posted December 4, 2020 Might be worth checking the timing chain tensioner first ? Just a thought. Link to comment Share on other sites More sharing options...
Pete Lewis Posted December 4, 2020 Report Share Posted December 4, 2020 does the old screwdriver stethoscope locate a zone ?? dont get it in the fan or you end up in A & E to get it extracted !!!!!! Pete Link to comment Share on other sites More sharing options...

Conor L Posted December 4, 2020 Author Report Share Posted December 4, 2020 I did suspect it was a bottom end issue definitely not the exhaust hitting anywhere which I kind of hoped for aswell. Will dig out the long screwdriver tomorrow and have a listen I suspect around cylinders 3 & 4 but will check all the other areas too like timing chain, cam sort of areas and will report back. I've just been put on to as and when required at work so that'll give me some time to pull the lump and see whats going on. Haha and don't worry have the T-shirt for things like that using a proper automotive stethoscope could never find the end after checking a water pump on a Toyota Avensis Link to comment Share on other sites More sharing options...
poppyman Posted December 4, 2020 Report Share Posted December 4, 2020 You could try pulling a plug lead off each cylinder while the knock is there.... If it disapears it's more than likely a big end rather than a main. Tony. 2 Link to comment Share on other sites More sharing options...
NonMember Posted December 4, 2020 Report Share Posted December 4, 2020 Just to throw in a wildcard, I did have a very similar noise when a head gasket failed between two cylinders, but I'd expect that to cause rough running / unsteady idle on a four cylinder. 1 Link to comment Share on other sites More sharing options...
Conor L Posted December 5, 2020 Author Report Share Posted December 5, 2020 Just been out to have a little listen around thankfully no trip to A&E needed. Removed a plug lead at a time noise was still there, checked around with my long testing screwdriver couldn't really anything alarming which was strange checked around the lower block area, top of the engine and around the timing cover even pulled out the dipstick incase the crank was catching that. Engine does run a bit lumpy but that's most likely because its needs tuning. Thinking of removing the sump to have a look before removing the engine 🤔 Link to comment Share on other sites More sharing options...

Nick Jones Posted December 5, 2020 Report Share Posted December 5, 2020 Oh dear. Does sound a bit “endy”. Crank pulley nut, flywheel bolts, drop sump to check shells..... If it has eaten shells, question that follows..... is why?! Nick Link to comment Share on other sites More sharing options...
Conor L Posted December 7, 2020 Author Report Share Posted December 7, 2020 Well this is bizarre. Yesterday my mate came over to have a little listen to the noise, started it up take it up to 2k with the choke on as before and could only just hear the noise, warmed the engine up a bit pushed the choke in took the revs back up to 2k and the noise was gone! Initially I thought it was a knock but we determined it was more of a rattle anyway fired it up again today and there is no noise at all with and without choke. Can't quite get my head around it however I'm not complaining think I'll just monitor it and have a good listen every now and again and carry on as before especially as my order from Owen @ Park Lane Classics arrived today.

Bordfunker Posted December 7, 2020 Report Share Posted December 7, 2020 On the one hand that sounds like a result, but does leave that niggling doubt in the back of your mind that it might come back. Karl 1 Link to comment Share on other sites More sharing options...
Anglefire Posted December 8, 2020 Report Share Posted December 8, 2020 Not something as stupid as the sump is a bit too small and now its been beaten into a shape that clears the moving bits? 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted December 8, 2020 Report Share Posted December 8, 2020 well thats a result ............... without knowing why we have all read the posts on drainback but can a journal get a air lock in the lube supply ??? 1 Link to comment Share on other sites More sharing options...
NonMember Posted December 8, 2020 Report Share Posted December 8, 2020 44 minutes ago, Pete Lewis said: but can a journal get a air lock in the lube supply ??? I would have thought it's more than possible for a rebuilt engine to have a semi-soluble blockage in one of the oilways. That would give symptoms of lack of lubrication to some part of the engine for as long as it took to dissolve - which might mean until the first time you get the engine properly warm. 1 Link to comment Share on other sites More sharing options...
