Thanks for all the info , after cleaning the top of the barrel off I came to the conclusion that the amount of drop in the liner was not as much asI first thought more like just under a mm.
Any way I took it to a local machine shop where he said it wasn’t too bad so he pressed it back to the correct position, What I think I need to do is to pin it to stop it happening again , What do you think ?.
Thanks again all for the very interesting information very much appreciated .Win.
I have seen engines that have been running OK with this amount of liner drop and on that basis you could have ignored it...However, that would be a gamble as the liner has moved, so obviously there is an issue with the fit...If a piece of the shoulder does break off due to the pressures being exerted on it the piston, rings, cylinder bore, valve(s) and seats are all potentially at risk of damage from the piece that has broken off being loose within the combustion chamber...I should note here that I've seen and had to repair this type of damage more than once...
'Best practice' is always the correct, if not the easiest or cheapest, course to follow and the procedures for putting this problem right have been detailed in previous posts...I agree entirely with Mark on this one, including his comment about your machine shop who have already failed to give you sound advice IMO, or maybe they just did what they were asked to do?......Ian
Ok Thanks again All , well I have a decision to make eh, sounds like there’s only Only one proper one . As we say here in Oz she’ll be right .
Hope that you are all keeping c19 away . Win.
I have seen a 350 Gold Star eat a liner that was of course wron and slid down the bore.
The con rod then chomped off bits till eventually one of the bit gat stuck between the rod & the flywheel web,,,,, not pretty.
So remember there can be unforseen consequences
