Renault Clio II 1.4 16v - How do you bleed the hydraulic tappets? - steve is trying

Hi, I'm in the middle of a de-coke of the Mrs's car. I've been told I need to bleed the hydraulic tappets once the head goes back on. Could anyone out there explain how to do this please? When I took off the cam cover, I discovered two of the head torx bolts had been rounded off some time in the past. I managed to drill them out and kept the swarf from going into the engine with lots of tissue in the oil chambers around the two bolts and a few well placed small magnets. Do I have to replace all of the head bolts or are they available seperately? Thanks in advance for any advise as it will be appreciated. Steve

"Decoke" - that brings back memories form the dim and distant past.

Not sure about your Clio, but all the vehicles I have had with hydraulic tappets do not need bleeding at all. There may well be a bit of a ratlle until oil pressure builds up and fills them, but after that it should be fine.

If I was you I'd replace the head bolts as a set - probably not much more buying a set from a motor factor than buying a single from a dealer. If they have chewed a couple of them up, who knows how much they may have over torqued and stretched the rest.

A decoke how quaint.

I dont think that you need to bleed hydraulic tappets.

I would replace the set if they are worn.
