knocking

[nitrosteve]

my clone is making a faint knocking noise at idle. it sounds kind of like a dull thumping. any clues on what this could be?

Two of my CHICOM engines do the same thing A Greyhound 5.5 and a Predator 6.5.
I'm not sure but it might be the "splash" foot slapping the oil level.
It does not seem to hurt anything and the engines do not miss a beat.
Perhaps a member has the skinny on what it is.

my predator does the same. its the lifters...its normal

 

[nitrosteve]

it sounds like its more from the case.

 

[Mini420]

is it broken in?? i heard the same clink/clunk noise from the engine case for a bout a hour of break in.

Mine sounds like its gone now:thumbsup:

My predator 212 did it too then stoped. Have you made any upgrades

 

[nitrosteve]

bone stock and it has about 60-70 hrs on it

Did you get the warranty? If so go trade it in.

 

[nitrosteve]

its been almost 4 years

 

[vwfan79]

well the predator engines are on sale for $99 right now go get one and run yours till it blows then do a swap or just run yours. IMO if your running it stock and you have been running it for 4 years its probably not worth messing with it. Not trying to blow off your question/concern but if it were me I would just go drop the $100 and get a new one.

That's actually part of the problem. Blow it up,throw it away,and buy a new one.
Open it up and see what it is and fix it for less than a hundred.:shrug:

 

[vwfan79]

Yes but can you buy the stock parts to fix it for under $100, don't forget to factor in your time too.

You say it's 4 years old just keep riding it and change the oil regular. It will probably last a long time and if it goes boom just get a new one. At 99.00 + tax it's not worth taking apart. Your time is worth more than that.
