Cam Chain Tensioner

[Jamie_SV]

Hi there,

Removed the front cam chain tensioner today due to rattle noise. Followed all the instructions about retracting the plunger and removing the complete unit. Manufactured a retaining tool to hold it inplace while i screwed the tensioner back into engine. I had to physically push the tensioner back into its place against whatever it pushes down and screw the bolts in, now when i removed the retaining tool the plunger did not move at all. It is free to move when out as i cleaned it and checked it would return.

Should whatever it is pushing against be tight up against the tensioner when putting it back into the engine?

Any thoughts?

It's possible the valves are in just the wrong place and the slack on that side of the chain is being taken up, so not allowing tension to be removed.

I would pull front valve cover to check for teeth jumping and move the engine slightly in forward direction. Or maybe wind it over on alternator bolt several times to make sure nothing unpleasant's going on.

Cheers, will go out and give that a try. Didnt want to try turning the engine incase i royally bugger something.

Very important to turn engine over many times with the alternator bolt after any work at all on timing gear to make sure nothings binding.
