Water is not supposed to be there... 3 Attachment(s)
Well Its not often I get let down but it wouldn't start at work ..clunk was all I got. Eventually it started and I drove home and knew something was not right it was running on 6 -7 cylinders, vacuum gauge was down and fluctuating.. After pulling heads this is what I found :eek: looks like a crack in no.8 . I built and have been running this engine for about three and a half years..:rolleyes:

Re: Water is not supposed to be there... That's not the end to the day anyone wants. Is it repairable? Can it be sleeved?
Hoping for a speedy recovery, if its possible. |
Re: Water is not supposed to be there... That's not good!

Re: Water is not supposed to be there... Yep - that would do it! Has had water in the cylinder for awhile - can see the rust pitting.
My guess is that you should be able to sleeve that one hole, put new rings on the piston and be good to go. Given that you had a starter "clunk", then you most likely had a lot of water in the cylinder and hydrauliced (sp?) the engine. I would have the rod for that cylinder checked for straightness and check the rod bearings. |

Re: Water is not supposed to be there... Might be dirt or something but it sure looks like a burnt exhaust valve in #5 cylinder.
And to me the overall condition doesn't look that great ether. |
Re: Water is not supposed to be there... looks like the head gasket has problem at the rear water passage, the black areas usually are suspect places for leaks on that type of gasket
where is the suspected crack? ---is it the lower stud? ---how large is the bore> I don't think it is a crack most likely if it was cracked it would go all the way to the deck and over to the hole |

Re: Water is not supposed to be there... Looks like a crack to me. You'll need to pull the motor down to sleeve it anyway, so I'd do a pressure test on the block - you'll then know for sure where the crack(s) are.

Re: Water is not supposed to be there... That is sad.....

Re: Water is not supposed to be there... do you have a armature growler? it can be used to magnaflux, and i used to use .001-.002 cuts on rotor lathe to make 'powder"
is it a blind stud hole? |
Re: Water is not supposed to be there... A weak spot on 21 stud engines. Had one let go on a fresh rebuild. It distorted the top of the cylinder bad enough to lock up the engine.

Re: Water is not supposed to be there... Rob , price some freight, I have a complete 24 stud 221 engine you could have.
and I second the look at the gasket, I had one just like it on the 33 the other month, the black areas specially. Lawrie |
Re: Water is not supposed to be there... If it comes down to it Lawrie I will do thank you.
I need to take it out and assess it further , Ive been dawdling on the other [backup] engine so now I have to get the skates on and finish it so I can swap over , I still have not found 3 1/16 + .100 rings :rolleyes: Keith dropped off a sleeve the other day so it could come in handy. ;) |
Re: Water is not supposed to be there... get onto Hastings or grant for the rings.

Re: Water is not supposed to be there... Rob, I have some new model A engines coming over from Perth freight cost is very good, maybe not there other way.
And get a crack tester kit from Blackwoods and check it, but I think it will be the gasket. Lawrie |
Re: Water is not supposed to be there... So the head gasket leaked into the cylinder and hydro locked causing the cylinder to crack correct? Had that happen once on a 428CJ.
