If you've seen my other post on air mixture screws' you'll know my engine had been rattling. So I drained the oil today and found it was contaminated with coolant. Hmmm. I guess I didn't get off so lucky with the cam chain issue. I took the top apart and removed the cam cover. Nothing looks odd up top. Not sure where it's getting in.

Well I pulled the oil pan today in order to inspect the water and oil pump. Good thing because I found a gob of plastic and metal shavings. Who knows where those shavings got to. Yeesh!

All the crap was stopped by the oil sucker screen.

Got the bike all back together with oil pan and pickup screen all cleaned up and new seals in water/oil pump. Started her up and still has that nasty top end rattle. I thought oil starvation but I guess not. This is beyond my capability now. Any advice? Anybody wanna buy a cheap project bike? I am frustrated with myself!

I was hoping this wouldn't occur.

I would think the strainer and oil filter should have prevented debris from getting into the oil paths feeding the head.

Are you sure the cam chain tensioner is installed / adjusted properly?

You just adjusted the valves with the cams out? Any evidence of debris in the head? I would think the cam bearing surfaces would be chewed up quickly by oil starvation. Any evidence?

Something wrong with the timing chain from operating in the debris and against the failed tensioner? Chains get loud. Don't forget suggestion about cam chain slipping a tooth on sprockets.

Does the noise speed up with the RPMs? I'll have to re-find your video and re-listen.

No evidence of debris up top during the last time I had it open. Cams turn smoothly. Valve spacing are within spec. I followed the manual with regards to adjusting tensioner. Basically you hold the plunger back by keeping a screwdriver in the screw at the end while bolting it on. Then release the screw and let it go back out providing tension to the chain. The chain looks fine too. Yes noise speeds up with rpms.

I'm wondering if somehow the valve guides got damaged.

Why would valve guides make noise? Leaking oil/fuel and smoking but the noise doesn't fit.

I re-listened to your youtube video. Is it louder on the cam chain side of the motor? Have you listened with your ear to a screwdriver (orange juice and vodka) touching the tensioner.

The noise in the video at a distance is hard to pinpoint.

So you replaced items 10 and 11? Did you replace 6? Is it worn so the screws are touching the chain?

Did you replace the cam chain and cam chain tensioner? If not, that would be the most likely cause for the noise. I had a cam chain tensioner that was rattling and replacing it with a new one reduced the noise from that area. If you remove the small bolt in the end of the tensioner with the engine running and watch the end of the internal screwdriver slot with a flashlight, is it bouncing around, especially when you rev the engine? If so, I would replace it. And to be honest, I wouldn't trust that cam chain after being put under the amount of abnormal stress it saw.

I did not replace 6. I looked at it and it did not look worn to me. I tried the screwdriver to the ear trick but could not pinpoint anything. Honestly the cam chain did not seem bad at all but all I did was clean it and look at visually so am not really sure. I will take a look at the internal screw
Thanks for the ideas.

I went out and listened again and it's definitely louder on the chain side of the engine. Couldn't see the screw bouncing around. Anyway I just ordered and new cam chain, tensioner and that little guide at the top (no. 6). So off with the top again. Ugh!
