Re: Piston slap or valves?
You can even do it without draining the coolant, just unhook the radiator and let it dangle on the hoses (supporting it on a box or similar).

I think you are right - as long as one is careful (maybe wrap the radiator in some bubblewrap to protect it) then I think there might be just enough room to do the checking bit. If the shims need changing it might be a bit cramped, but one could decide whether to remove the radiator for that bit. Sent from my iPad using Tapatalk |

Re: Piston slap or valves?
Based on the vid clip (and I know microphones can distort the sound so just guessing) I would be thinking cam chain rattle especially as it quietens off briefly when you increase the revs.

A lot of SVorgers in USA post that cam to valve clearance actually gets slightly larger as engine warms up, so that should get noisier as well.

Re: Piston slap or valves?
It will be interesting to know what the problem is. It just sounds like a worn cam chain to me. I am probably wrong. I often am

Have you managed to eliminate the clutch/transmission from the list of suspects yet (or not perhaps)? Have you had any success searching for the noise with a stethoscope? I'm intrigued - what is causing the noise? Alan |

Re: Piston slap or valves?
I think I'd want to be looking at the cam chain, the tensioner, and the tensioner blade.

I've not gotten round to checking clutch yet but I will get to it this week! Along with a stethoscope! As far as cracking the cover off for checking clearances, do I need a replacement gasket or is it a re-useable rubber gasket? Also I should be able to depress the cam chain and check whether it's loose while the cover is off right? Cheers. |
