    Timing Chain Oil Seal

    Hi,

    I am in the process of installing a speedi-sleeve and replacing my timing chain oil seal. Honestly, the oil seal was probably fine and all I needed was the speedi-sleeve. Anyways, the old oil seal and new oil seal look completely different. Curious on your opinion. Attached are photos of the old one installed and the new vs. old side-by-side.

    The old has a full metal collar, is a about 11/16" in profile height and stamped with "Made in UK 480003C". It looks much more substantial. The new one is a US made SKF seal from NAPA, Part No. 17386. I've always found NAPA parts to be quality. Anyway, it is only 5/16" in profile height and appears nearly flimsy compared to the original. The actual rubber seal looks comparable, however. In comparing the two, it is clear the new seal will ride further up the hub (further way from the crank) - if that makes sense.

    Appreciate any thoughts

    Bob

    Never re-use a seal. I like you, would prefer the larger seal if I had a choice, but I also would have no problem with your new NAPA seal. You can install at different depths to control where it rides on the hub. Just be sure to make sure it is installed squarely, not cocked.

    Hi

    Just to close the loop, a few hundred miles and the new oil seal and speedi sleeve appear to be up to the job. Completely dry which is a significant improvement. I used to get a drip every few seconds for a full minute after engine shut down - imagine 20 drips and the mess that would make! Oil pan was coated too. Now all is dry except for the occasional drip from the rear crank seal.
