Tell me a bit more about enlarging that drain hole...There is a steel tube (maybe 3/16) at right angle to the rear about 1/2 inch down in that hole. The hole is dead ended down further. The steel tube drains fluids to the rear from that hole and down in front of the fly wheel out just behind the oil pan. I do not want to dump oily fluid onto the flywheel from that hole so prefer using the steel tube. There is no way to enlarge that steel tube without getting inside the bell housing. I will study this further and try to invent a way to more effectively drain that area :read2: |

That will work ......just drilling a larger hole and dumping into the flywheel area is prolly better than drowning out your starter when washing the engine :D |

The cam covers are back on, and the whole thing should be done this weekend. Its freezing in my shop, so I cant work out there too long. I found a mouse nest in the starter valley. That's been there since I dont know when. But even with that crap in there, the larger drain hole did its job and drained the starter valley. I dont want to pull the starter so I can measure the hole, but the hole isnt much bigger than it originally was. I dont think that drain tube is still there though. It may have been "Lost" when I did this back in the day. However, I remember doing the big hole thing because it wouldnt start once and I wasnt going to go thru that again. Especially after a GM bulletin went out regarding making the damn thing larger. They should have done this at the factory!!!!:icon_boun |
