engine question

[stephen12091985]

ok my engined knocked since ive had it and my piston ended up breaking so i was wondering when i put my new piston kit in if it still knocks should i replace the crank?

 

[Racer X]

not an expert so dont quote me but id say replace the crank

 

[stephen12091985]

yea i was going to anyway if it knocked still i was just wanting some opinons.ive heard that blasters do knock and someone said it was normal on here but my friends blaster didnt knock

 

[FLOTEK]

that knockwas probably piston slap from a loose bore that was neglected past its service limit and possibly not the rod bearings get the bore checked out for wear and size ,dont just replace the piston and crank and hope it was a bad crank

no i got a new piston and its getting rebored to match the piston and i should get it back tomorrow or tuesday
