2003 NAVIGATOR #6 CYLINDER COMPRESSION
when you talking about drop #6 cyc, did you mean you had to replace the piston and the rod its self? if you had to replace piston and the rod, what took place that you had to replace them? did you throw a rod or the rod was knocking so you had to replace it. If you replace #6 piston due to a rod knocking or you threw a rod for the second time i wonder if that mechanic inspected the main crankshaft it self. if you threw a rod or it knocking 90% of the time you probably have damaged your crankshaft by scuffing it. scuffing the main crank will not be the same, it can be a hair line scuff, it will take no time before your crackshaft will start wearing out the new rod bearing. scuffing up a crankshaft without having machine shop turn it to smooth out any scuff or damages, it will eat and chew up the new rod bearing like its no tomorrow and your rod will knock again. keep in mind, sometime crankshaft is too damage or scuff to be turn or repair it must be replace. There is no reason if that mechanics done it correctly, you should not have any problems from the same cyclinder; it tells me he did a horrible job although he may got in too deep into the engine and decide to cut cost without fixing it and went ahead and fix it knowingly he should done a proper job. If you have to keep placing the rod and the piston due to the crankshaft wearing out the rod bearing, it tells me you have a bad crankshaft. its not worth replacing and fixing due to the cost factor. you better off to get a used motor from a junk yard for 800-1000 bucks. I hope that help some..
