In-Car Hone and Rings????
« on: July 13, 2017, 03:06:38 pm »
I know this is not the best way to do this, but I would like a few opinions anyway.

Why do this??? Money, facilities, skill, expected life ??? Take your pick.

Without removing the engine, can the cylinders be honed, if needed, and the pistons, rings and rod bearing be replaced with new parts if needed?? If the cylinders and pistons are not a complete disaster, then just hone, and put in new piston rings.  Also, new big end rod bearings.
If the honing is a problem(contamination), then just replace the rings????? What would be the minimum???
Couldn't  the crank be covered up and kept clean? then the block rinsed??? (I can just hear the moaning!!!!)

Might this be acceptable on some level???? Or will it do no good at all???
 I can’t pull the engine myself. This would be done with having the head rebuilt at a local shop.

This is a practice formerly referred to as "Blue Inking." Best used when trapped behind enemy lines.

Use what you can to keep grit out of the mains: tin foil wraps, black tape, etc.

Hope the cylinders are remotely round.
The mask and the shot(s) are actually an IQ test. If you are wearing or circulating, you just failed the test. I can't feel sorry for you.

It's doubtful you'll have much improvement over what you have now if you take that approach. Cylinders don't wear evenly, they tend to go egg shaped. Without a proper bore you're just tossing money in the engine bay without much to show for it.

Rent or borrow an engine lift, you can get the drivetrain out in a few hours...

Maybe consider a ridge ream job if the ridge is too large.

It looks like that could be done without pulling the engine too.

This car has been so "babied" for 26 years that I'm hoping it will have paid off in only minimal wear.
