My beloved red block (B230FT) has had piston slap in the #1 bucket since new. With the cylinder head off, I can see the cylinders all still show the factory cross-hatch machining marks.
I’m doing a cylinder head refurbishment and pulling the engine at this point is academic. My Volvo mechanic friend says that in the day, “they all had piston slap”, and to ignore it. The only way to fix it is to bore and oversize the pistons.
Question: Anyone out there in Brickboard Land experience the same condition (sound similar to ignition knock with a feathered throttle position), and did it annoy you enough to remedy with an overhaul?
Thanks as always.
