Honda B16/B17/B18 Oil Dipstick Tube 11111-PR3-300

Honda B Series Oil Dipstick Tube - 11111-PR3-300

Snapped your dipstick tube during a swap? Got a crack that's letting dirt into your crankcase? This is the genuine Honda OEM replacement - part number 11111-PR3-300 - for B16, B17, and B18 engines. It's the metal tube pressed into your block that your oil dipstick slides into. When it breaks, you've got two problems: you can't read your oil level accurately, and you've got an open hole dumping debris straight into your oil. Don't run it like that.

Why These Tubes Break

The dipstick tube sticks out of your block, which makes it vulnerable. It gets bent when you're reaching past it, it cracks from years of vibration, or it corrodes and snaps off at the base. Engine swaps are probably the most common cause - you're pulling a motor, something catches the tube, and it either cracks or breaks clean off. Either way, a broken tube means your dipstick doesn't seat correctly, so your oil level reading is off. Worse, that open hole in your block is a direct path for dirt and debris into your oil. Contaminated oil destroys bearings. Replace it now.

Genuine Honda OEM - Not Aftermarket

This is a real Honda part, not a generic reproduction. It fits your block exactly because it's the same tube Honda installed at the factory. Drop the old broken tube out, press this one in, and you're done. It comes with the O-ring that seals it to your block - don't skip seating that properly or you'll have an oil leak right where the tube meets the block.

Installation Notes

Before you press the new tube in, clean the bore in your block. If there's old O-ring material or debris stuck in there, your new O-ring won't seal flat and you'll get an oil weep at the base. Press the tube in straight - don't angle it or you'll pinch the O-ring and compromise the seal. It should press in with hand pressure. If you're forcing it, something's not aligned right.

Need the Dipstick Too?

This is the tube only - the dipstick is sold separately. If your factory dipstick is straight and not damaged, you're reusing it. If it's bent, missing, or you need a fresh one, order the Honda B series oil dipstick honda b series oil disptick 15650 p30 000 (part number 15650-P30-000) separately.
