Tappety ??

[chrissrush]

Just recently I have noticed that occasionally on a cold start there is a definite tappety sound that lasts 3 or 4 seconds maybe before going away. Sounds sort of like a hydraulic tappet that builds pressure up and "clears" itself IYSWIM


I can't think what this is. Any thoughts?

Probably vanos ...

No hydraulic tappet on S54..

I would get someone to lift off the cam cover and just check for cam/ follower wear..

Oil level in the right place?

 

[chrissrush]

Yep, oil level is fine.
It's in for an oil service Tuesday I wanted to get an idea before talking to the garage

And it has an interim change so it's only done 7000 or so on this oil.

The oil may sort it, 7000 is quite a long time on oil.

Really? In the book IIRC it's something like 14,000 between changes??

I keep mine to the 7000 mile or so oil changes - mines now on 140k miles (117k in my ownership on engine replaced at 23k).

It also gets a oil/brake fluid change after Ring trips - no need for me to do it before as it's only usually been about 3 months since the last one

 

[RedUn]

OP, did the oil change fix it?

 

[chrissrush]

No change to the noise, I checked the book and I'd actually done less than 7000 on the oil. Wondering if I'm being over sensitive or if there is a problem developing.
NB service reset indicates 15500 miles to service. I'll change it in 7500!

I'll make an effort to record the sound it and check with the specialist I use.

I thought mine made a tappety sound. Took it to cpc for its service (oil service) and Phil confirmed not really a noise to be concerned about as these tend to be noisy tappety type engines and it would be pretty evident from the sound if it's a bearing or follower type noise. Although he did show me a black 06 z4m he was working on that had had worn followers and spun a bearing (not sure if the owner is on this forum)! Expensive repair bill!

If your sound is a genuine tapping sound an oil change will do nothing, the problem with a sound clip is it could be a loose mount bolt of some sort or it could be a serious issue, take it to a trusted indy

I have that sound from cold too, and my indy tells me it's normal. It hasn't got any worse but it is a little annoying. I'm still used to creamy smooth italians..
