servicing yourtappets or new ones would probably help - or an oil cooler.

sounds like a sticking tappet. .Only real solution is to replace them or at least remove them, disassemble and clean them.

Nice one Rae, I didn't know they could be stripped. I'd recommend putting each small spring on a cable tie as soon as they're removed, preferably a yellow or orange one. Much less likely to lose them then. But you could still lose your little balls!

LOL, or do them one at a time and you don't need to cable tie the spring to stop you losing it!

Won't be cleaning mine, new ones will be going in as I'm changing the cam, but I would only do one at a time anyway. But with a spring that small breathe too hard and it could be gone!
