OK, I am sorry, but I have never been here on a motor before.(well, I have replaced visibly failed components, but not much measuring!)I now own a feeler gauge, and dont know where to stick it!I am presuming I am measuring the gap between piston top and cylinder?or rings and cylinder?A little advice here would be appreciated!THANKS!-Brad
OK, Just a quick minute with cylinder #1 and #4, I found #1 took a .406mm #3 took a .356mmthat is what would slide in between the cylinder wall and piston, but not past the first ring. The way the leaves of the gauge slid into the gap, I was trying to be careful not to mar the cylinder wall.I will go back and check 2 and 3 in a minute.-Brad
well so far its looking good... #1 had the best compression, but the most cyl wear...
OK, so I definitely should not be able to get that particular leaf of the feeler gauge in the gap at all, then? (it doesnt go in too far!) Quotewell so far its looking good... #1 had the best compression, but the most cyl wear... And by looking good, you mean like we can keep the pistons and just do rings?Thanks, JT!I totally appreciate your help!Ill get back with numbers from all sides on all 4 pistons.I also suppose to be fair I should try this in the middle of the cylinder, so my "ring ridge" does not make things look better than they are?-Brad
The head is now at the head shop.For $100 they clean it, dis assemble it, and check it for straight and cracks.He was familiar with the cracks inbetween the valves, and said as long as it does not go through to the port, they will just peen them to keep them from spreading.I trust them, and if it needs guides, they will install, and I want new valve stem seals regardless.They also may have some help on a custom made MLS gasket. They know of a few companies who can make them.Now, my only concern is the block.I need to figure out how deep I am going: Rings and bearings, or punch it out and go up on pistons. I may have a good line on NOS oversize pistons, which may help lessen the blow.Is the feeler gauge the best bet towards determining the block's condition, or should I get a micrometer to measure the inside of the cylinder wall?And, my ARP's showed up today... very cool!Thanks,BRAD
Part of me just wants to do what I need to do in the head, ARPs and MLS, and do rings and rod bearings and hope for the best.Am I crazy?-Brad
