breaking in my engine

[ratmraptor]

My engine has tick at low rpms... what could it be

 

[Gen1Pat]

Without hearing it, it's hard to tell. Could be some timing chain noise, slight valve train noise, etc.. If you could post a vid that would be great.

 

[ratmraptor]

That would have to wait til tm.

 

[ratmraptor]

If its timing chain noise what would be the possible outcomes of that.

at idel? moving? i m going with valves

 

[ratmraptor]

Just start up and putting around the yard.and giving it a little up the driveway gas

 

['00 WO-YA!]

Most of these machines have a lil topend valvetrain noise. In the event that it is timing chain, well, it Aint gonna heal up, Lol! It won't be good man.

Wow. If its the timing chain can't I just replace it or tighten it?

Like 00 said, warriors are not the quietest engines. As far as the timing chain goes, get the engine on tdc and pull the cam cover and see if there is any slack in the chain with just your fingers. If there is it could be either stretched chain, or tensioner spring weak. Also check the valve clearence and readjust if need be. What did you have done to it exactly.

 

[ratmraptor]

Just rebuilt. New piston. Bored over 1mm.

Could be cam chain but im saying you rjust hearing the noisey ass valves these motors have. No getting past that.

 

[Gen1Pat]

I would check the chain and the valves like I siad. If it is running fine otherwise I'd have a hard time believing it's something major. But, you're there and I'm not, I hate to make assumptions I would like to hear it when you get the chance to post a vid. Warriors are known for a top end tic.

I like the way you think. But I mean I will just have to take it back ti the shop. They put it might not have put it back together correctly. That's on them.

Pull the tensioner off and check it and how far it is pushing the chain

 

[ratmraptor]

Let me post a video before I do anything

 

[ratmraptor]

I have a video on youtube. But its hard to hear the tick. My username is mrmansfui

 

[JonS]

copy the web address of the video and post it here. it will automatically show the video.

 

[beastlywarrior228]

i didnt hear anything unusual

Yeah when I started it today it seemed to have quieted down a bit. So I guess problems solved. Hopefully

 

[Gen1Pat]

I couldn't find your vid but its most likely those valves. Also, if they did a valve job it may take a couple of times of getting it hot and letting it cool for the valves to seat "harder" into their seats. Let that metal expand and contract a few times and they do quite down some. I've had times where I've gone to readjust the valves after or during a breakin period and they are a few thousands tighter than what I set them at.
