Leave It, ReRing or New Pistons

Postby haluska » Sat Aug 29, 2020 9:35 pm

I have a D16Z6 that I swapped into the car and I think it had a blown head gasket. It's been nearly impossible to get started, often running the battery dead before I could get it started. I tested so many things trying to figure it out. I'm planning on pulling off the head tomorrow, inspect / rebuild it. I'm debating what to do with the block.

Here's the compression numbers with the engine warm: 190, 182, 175, 178.

I don't know for certain how many miles are on the engine, I think he said 130k.

So what would you do? Leave the block along, re-ring it or do new pistons? I'm not planning on racing it, I just want it to be reliable.

I think determining where the compression leak is will help you decide what to do.

Decided I didn't have time to rering this year so I left it alone.

Your low and high cylinders are within 10% of each other, and 175 is still a usable number. You might have other issues at hand.

I've got a filter for my mouth, it just isn't a good one.

I resurfaced and cleaned all the valves, new seals and put in a new Honda OEM headgasket. I found nothing noteworthy wrong on the cylinder head or air intake.

The starting issues remain. I think something is wrong with a cylinder or two or I have something wrong with the crank position sensor, but I'm having to put it off till next year as I ran out of warm weather.
