chilli Posted March 20, 2006 Share Posted March 20, 2006 well on the shim that is down, you can clearly see that the cam lobe is pushing it down (lobe is pointing down) - so you need to rotate the engine a bit (as mentioned, put it in gear and move a litle) and see if it comes up ok...

terribleturner Posted March 20, 2006 Author Share Posted March 20, 2006 In a word Bollocks and double bollocks. Yeah it's all fine there, shim popped right back up But at the same time the plug to the 2nd spark plug of the coil pack crumbled in my hand Will i ever get a break Quote Link to comment Share on other sites More sharing options...

Robert Posted March 20, 2006 Share Posted March 20, 2006 if you need a spare coil pack connector i have a few spare you can have mate. Quote Link to comment Share on other sites More sharing options...
geoffvalenti Posted March 20, 2006 Share Posted March 20, 2006 James If it was anything to do with camshafts and shims, it would make the knock at all engine speeds. Unfortunately your noise sounds suspiciously like a big end In fact if we we running a sweepstake on it, I'd definately put my money on big end(s) Does it appear just when the engine is revved, and can you hold the revs at a point where it rattles all the time? If you rev the engine, can you rev through the noise. Does the noise appear mostly when the engine is "running light"? Quote Link to comment Share on other sites More sharing options...

Does it appear just when the engine is revved, and can you hold the revs at a point where it rattles all the time? If you rev the engine, can you rev through the noise. Does the noise appear mostly when the engine is "running light"? It only seems to be when the car is revved or just turned over. At one point you couldn't hear it at 2000rpm, then tried 2500 and it was there. Dropped to 1000 and then back to 2000 and it started again. Got some video of it being held at both 2000 and 2500 that i'll post later. Quote Link to comment Share on other sites More sharing options...

Shame CW isn't reading this thread, as I'd welcome his input as confirmation. Sorry to be a bringer of doom, but better it fail now, than when you've just got the single on it Quote Link to comment Share on other sites More sharing options...
Digsy Posted March 20, 2006 Share Posted March 20, 2006 When you turn it over manually, are all the tappets coming all the way back up again? I.e when the cam is on its base circle (zero lift) are all the tappets in contact with it? Quote Link to comment Share on other sites More sharing options...

Ah, sorry i was lazy and put the cover back on and turned the engine over once with the key so didn't actually see anything moving. Quote Link to comment Share on other sites More sharing options...
geoffvalenti Posted March 20, 2006 Share Posted March 20, 2006 Honestly guys, if its a valve train problem, like a stuck valve (but it would be missfiring then anyway,) or a misplaced cam follower, it'll make the noise all the time the engine is running If its a bigend it'll be more noticeable when the engine is running light, or revved gently. A sort of "Burrrrrrrrrrrrrrrrrrrrup" noise IYSWIM in fact JUST like the noise in the first video Quote Link to comment Share on other sites More sharing options...

But I agree, its all looking like something more serious. Quote Link to comment Share on other sites More sharing options...
letmeshowyou Posted March 20, 2006 Share Posted March 20, 2006 sorry to say it James but it sounds very big endy to me from the video. on the subject of torque convertors - I'm still convinced yours was playing up at Pod when we were there!

A sort of "Burrrrrrrrrrrrrrrrrrrrup" noise IYSWIM in fact JUST like the noise in the first video I'd agree, this rattle on load (change of RPM) is classic big end sound and I've had it before on an engine with a light scoring on the crank big end journal - that required a replacement crank, con rod and bearings! Obviously you can't be 100% sure of anything until it is all taken appart, but I don't think it would be cam related with that sound or it would just go with the revs, not with the load too. Is the spark plug idea good, anyone? i.e. remove one at a time and run on 5 to see if you can locate the cylinder / big end that may have the problem?

It may work, but it's really a moot point. The amount of aggro needed to pull the coil packs, just to tell you which bigend is knackered, when you've got to pull the engine out anyway. At the end of the day, once we've agreed it's a big end knackered, which particular one, is irrelevant Quote Link to comment Share on other sites More sharing options...
chilli Posted March 20, 2006 Share Posted March 20, 2006 true enough, just thought it might help reduce any uncertainty before commencing with more serious work... but point taken, it might not be worth the agro (are the plugs really that much agro to get out then?).

terribleturner Posted March 20, 2006 Author Share Posted March 20, 2006 OK Video time again. What we did here was run the engine at idle, then 2000rmp, then 2500rpm. Then we did it all over again. Now i could be wrong but im sure my cam gears used to be turning the entire time the engine was running before. Have i imagined this or not??

chilli Posted March 20, 2006 Share Posted March 20, 2006 I can't see the video (work connection foobared) but WTF! You saying they stop turning? well if they ever slip out of position the engine would stop dead or run like a dog, so I can't see how... You sure it's not a strobing effect with the video camera, did you see it with your own eyes or just on playback? Quote Link to comment Share on other sites More sharing options...

chilli Posted March 20, 2006 Share Posted March 20, 2006 must be strobing of the video surely? I'll have a look at the video when I get home, be amazed if they ever stop, think that is a physcal impossibility if the engine keeps running... edit, ooops too slow, thought so, will take a look later though as I want to see for myself Quote Link to comment Share on other sites More sharing options...
