Bore advice please

Stu · Post by **Stu** » Mon Feb 16, 09 9:00 pm

I hope the photo shows up ok, but when I finished stripping the block and got the torch out, all looked grand except one bore which had what looks like a rusty mark part way down. Is it possible that this is a problem from the water jacket it backs on to? What are the chance of being able to shift it?

Rubbed it down quickly and now it looks like the last pic. What sort of trouble are we in, in your opinions... Is honing likely to shift this, or is there a better (cheap) option?

stu, them rust patches is from moisture or water being sat in the bore , honing will prob take out the worst of it but remember dont go to heavy on honing ! if you want it better than that then a rebore is in order, if you just building a stocker then prob get away with it for a while

Will be a stocker, Jim. When you say " a while"... Is it advisable, or not? Limited funds and no machine shops close makes a re-bore more of a pain in the arse than it should be.

The ring set you use will determine what honing is required (stones) , get the block down the machine shop & see if they can clean it up , if not a rebore is not the end of the world , is this a standard bore? (4.320")

Looks like those cylinder walls need a hone anyhows.

Stop worrying , will all sort itself out.

Yes, Mate, standard bore. 3.910"

Was just going to order a standard ring set. Is that the right thing to do? Don't know anything about honing, never done it, so any advice on it gratefully recieved.

Probably the best advice, I know! Just erring on the side of caution, Adam. Only want to build this once, so we can concentrate on the 400 after that.

This is the practice piece, to get the motor back on the road quickly and learn from. The 400 comes next.

The ring set will say what stones to use.
