Tap tap tap vlick click click

I have v mild tappet noise on.my car. Adjusted them a year ago and change oil ever 5k miles.
This morning I started my car first time in 2 days to.a load enough cluck click.click or tap tap tap. It sounded like a bad bearing (freaked). It increased with speed as I revved. It got quieter and quieter and was gone in 30seconds. Not been there when I started 3 or 4 times since but car was warm etc. Is that tappet noise? Thought tappeys like sewing machine noise? This sounded more like one tap tap tap like a bearing it something.not sure. Might be just tappet noise.
Opinions or suggestions? I'm off to.read the archives now.

I'm not oo sure about the bearings but seems it went away when the oil was warmed up I'd be inclined to think it the tappets.
On the otherhand the noise just wouldn't be there all of a sudden, it would be progressively worse over time.

Actually if you dont drive your car as regularly as normal the tappets wont be full of oil and as such need time for the oil to be warmed up (so it is thinner) and can be pumped into the tappets. if it starts to happen every time you start the car its the seals in the tappets, if the noise never goes away the tappets need adjusting again, but your noise was just the tappet because they where dry

Hey guys. Thanks for your replies. I left the car from 9am ttill.6pm and no noise when I started it. Then left it overnight for 14 hours, no noise when started.I think it was a one off thing alright. Like Richard suggests, left for 2 days in cold weather something just needed oil circulated around.
Nct Friday cat going in tomorrow. Will let ye know how it goes. Not pre testing it at all. They always find something so ill just see what comes from it.
Cheers for the replies, not been on here much with new life commitments etc but always nice to drop by.

Hi McGon, nice to see you're still around

That happened me once too. Came and went and that was the end of it, cold day too just as autumn was finishing up, and was parked up for 2 days.

Yup. I think that was definitely it. No repeat at all.

I took out the miltek decat box today and put the cat in. Its less throathy and raspy at hhigh end, but still sounds v nice. Much smoother sound. No more bangs and pops listing off after hard acceleration probably think I'll leave the cat in though. Nct due yearly now and changing it every 11months would be a pain. Don't care about losing 5bhp it what not. Was more worried about it sounding like a micra. Sounds fine though ))

Yay.
