Funny Clunk Noise On Start Up

[WogsRus]

Hi Guys

Well i have this funny Clunk Noise on start up, especially when cold, it's like when the engine is just about to fire, it sounds like a pipe or something is hiting something else, and making a hollow clunk sound.

The noise, sounds like it comes from the pasanger side of the car, but when i open the bonnet, i can't hear anything when i start it up, it sound normal, so i presume it's under or at the back of the engine.

I have looked at the engine mounts, all good, no cooler pipes hitting anywhere that i can find, engine runs great, no noises or anythign else other then this.

Once the car is warm, the sound is not there most of the time, i presume that is mostly as the engine is a lot easier to start when warm.

There are only 3 or so clunk noises when you start it if you know what i mean, not an on going sound.

It doesn't sound mechanical, more like a screwdriver hitting the top pf a plastick bucket, exactly like that.

Any ideas what to look out for???????????

broken engine mount?

[WogsRus]

Yeah i checked that, the engine doesn't actually move when you start it much, and i certainly can't move the engine in either direction when off, looking arround the mount, it appears fine, no cracks. Will double check though.

maybe the exhaust it to close to the car body, the initial kick of the engine when starting is enough to hit

[WogsRus]

Check gearbox mounts too

Sorry to hijack a thread. Sometimes when in neutral, shift into reverse, give it some gas and it does this clunk sound. But its in the back or somewhere under the car. My ideas : driveshaft/subframe or gearvox moving ? Anyone had something like that before ? Thanks!

[WogsRus]

thanks guys, never thorght about the box, will have a looksee over the weekend.
