timing cover advice needed

So the water pump finally went out in my 83 & removal went good until I got to the stud for the power steering bracket....it snapped off just behind the nut & will not budge at all. I tried a stud remover & it snapped off about 1/4 inch into the timing cover, got the cover loose & it appears to be seized into the cover. Does anyone have any tips that might pop that sucker off? I figured I'd ask here before I break out the BFH & try smashing it to bits.

Other than to comment that an OEM timing cover is something worth preserving if you can, not much. So you have the timing cover off? Screw extractors are quite hard and you won't be able to drill it out. I'd try some heat and tap repeatedly on the edge of the broken extractor with a punch or small chisel to try and dislodge it. Once the extractor is out, left handed drill bits usually work well.

The extractor didn't break the stud did, & the timing cover is loose but will not slide off the busted stud. The kicker is I think the stud broke loose in the block because if I twist the cover some there's movement there but not at the end where it broke off in the cover.

If you got all other bolts out, loosen the pan, and you should be able to get the cover off.

Run a stiff thin wire into the hole and try work all crud stuck in there loose.
Hose the hole w/ penetrating oil/spray, and the cover should come off.
After the cover is off, you can work on the busted bolt easier.

I finally got it off....I had to break it though, there was a hole worn into the water channel with a huge chunk of rust sticking out from the stud & I guess that had it locked on. I put the piece with the stud in a vice & tried hammering it out & it still won't budge. & I was right about the stud being loose in the block....after busting off the ear it twisted right out by hand.

Whew! I'm glad that's over. New timing cover, waterpump, timing chain & gears, & oil pump. It's running really good now, & actually sounds a bit quieter without the worn out timing chain & bad waterpump bearings. The stud that broke was not fun to locate, but I managed to find a stainless stud for it.....sucker won't rust now. It kind of made me nervous doing the timing chain, reading all the horror stories of the oil slot not lining up with the hole. I checked the edelbrock set I had & the groove actually lined up, still makes me nervous though.

Glad you are back on the road and things worked out.

Be careful with the use of stainless though. The stainless stud won't rust but it will still corrode around the aluminum cover sometimes making it harder to remove later. Also, stainless is much softer than steel bolts and sometimes creates other problems like thread galling and bending. I thought I was doing myself a favor years back replacing most of my non load bearing bolts with stainless and then had to drill a number of them out after they broke trying to remove them. I've stuck with steel since.

I used anti seize on all the bolts, so hopefully if I ever have to take it apart again it should go smoothly. I even put it on the shank of the stud where it goes through the timing cover so hopefully it should be ok.

Glad everything worked itself out, I am about to do the same job real soon.

I will have to do a search on the oil hole thing so I don't screw it up.
