Question, I have an oil leak at the front main seal, its dripping ever so often and when you rev it up it has a small stream of oil. There was a small groove on the harmonic balancer but I think it was ever so slight. Should I sleeve it based on how much oil it's leaking? Or should I put a new seal at the same time? THIS isnt going to be fun in the boat!

So, I pulled the harmonic balancer and what do I figure out, there's a freaking hole in the timing chain cover for the crankshaft position sensor which my motor does not have! It's not a threaded hole so thinking my best bet is to purchase a crankshaft sensor that will physically fit and install it to plug the hole.

Progress Boys!

Glad you got it sorted and enjoy the rest of your season!

And yes I would just put a sensor in the hole.

I just picked up a small sensor and I figured out that there's probably not a sensor that will fit in the hole that the harmonic balancer wont hit, there's just not enough room. Even with the one I purchased I would have to pull the harmonic balancer to install it, and the body of the sensor protudes too much. I noticed while at the auto parts store there is another harmonic balancer that has less inside thickness than mine that would allow the sensor. I presume that hamonic balancer is for crankshaft sensored engines? I didn't want to put a different harmonic balancer on my engine not knowing fully the effect. I am wondering if my only option is to put my original timing cover from the old engine on this one? It has a hole but it's plugged up with a plastic piece that is part of the cover/not removable.

Questions:
1. Do I have the right sensor? My boat is a 2001 X-10, but it appears that most GM motor parts are from a 95-97 Chevy 5.7 TBI 1500.
2. Could I use a different harmonic balancer to keep from having to pull the timing cover? The one we found has same diameter and look, just from behind it the diameter is smaller.
3. Should I just man-up and swap over the timing cover? I really, really don't want to do that because of the amount of work and most importantly it might leak when i'm done and probably require new gaskets.
