Urgent assistance required

[tctommy]

 Hi,

 

Ive got a ca18det in an S13 engine. Freshly built motor. 3000km since it was put in. Just changed the oil and took it for a run. 

 I need some help diagnosing the noises. I'm hoping another oil might fix the tapping. But any help is appreciated. 

Cheers

That is a dry noise....no oil getting through to the lifters.  Air lock maybe?

I think I might agree with you. I'll take the lifters out next week. Thanks for the comment!
