Engine noise after replacing inlet manifold gasket

[weezlebub]

I had some oil sludge under radiator cap so I replaced inlet manifold gasket which was obviously broken. Repair went ok and on first startup all was normal for a couple of minutes then some noise started and got louder and louder so I switched off. Anyone know what it could be? Car ran perfect before doing the repair.

Noise starts at 0:15

At first it sounds like the belt ticking which can happen after pulling the engine apart and dropping oil/sludge on it,
Remove the Belt and start it up again and see if the noise is still there, [yes, you can run it without a belt for a minute]
If the noise is not there, re-fit the belt and use a Stethoscope would be the best to check to were the noise if coming from.
Changing a LIM Gaskets should not make any difference, fairly straight forward job.
You didn't leave any tools in the LIM Valley ?

Thanks guys you were right, it was just the belt making that racket. Had me worried there I stuffed something bad up.
Found a leaky injector now leaking from the top of it. hope it's just an oring I've got to replace on it

Here is a tip for a noisy belt,
Get a stick of dry lube, and rub it across the the belt ribs a few times in different places,
That always keeps the belts quiet.

You can usually find it at Supercheap & Autobarn

As much as "I hate Autobarn", they are cheaper than Supercheap
