engine swap Knocking sound at about 2krpm, is this a rod knock?

[E39guy]

Howdy guys!

 

I finally got my 02 drivable. I took it for a spin around the block. The concerning thing is that I hear a knocking sound at about 2krpm. The question is, what is it? I took a video, hopefully you can see/listen to it and help me start. I am thinking it COULD be detonation. It happens both in neutral and under load.

 

Here's a link to a video; http://vid230.photobucket.com/albums/ee225/240z4u/2002/20150808_095655_zpsxurxjy5w.mp4

 

Thanks guys

Sounds like your valves need to be adjusted.

[E39guy]

That had occurred to me. Ill give it a shot. Thank you.

Also, an M10 exhaust manifold leak at the head sounds nothing like a normal manifold leak- it's not easy to tighten all the nuts,

so often it doesn't get done.  They do loosen sometimes.

Thanks Gents,

 

The valves were loose (well at least a few were) so I did a quick dirty setup and it quieted down a bunch. I still may have a manifold leak, I'll check that out as well.

Evan, Also make sure you check the rocker lobes where they ride on the cam. Found the replacement febi rockers in my car had scallops out of them and they where slapping the cam. Caused a head rebuild that had major mission creep. Good Luck

I will definitely check that out, thanks.
