It's a '95 900 SE Turbo. The pulley cut through the aluminum in the side of the block. It may be the timing chain cover, regardless it's an oil leaking hole in the side of the engine that needs sealed.Probably need to know what car you're talking about.... but generally speaking the water pump is not adjacent to the block...
I don't understand why the cover has to be replaced and can't be repaired. Is there a specific reason?You have to replace the timing cover. It's not a fun job, but that's what has to be done. It can be done in the car, at least, if you want to undertake the job. This would be a good time to replace the timing and balance shaft chains, and all of the chain guides, too.
Thanks wal, I may try something similar. I have a lead on a good cheap car that won't last long, so it's a tough decision. She was a reliable car for years, but reaching the point that random things are failing. I'm sure the alternator will be next, the A/C is struggling in the AZ heat, the locks are getting slow....it just seems like it may be time to find a new, more physically capable owner for her...Not the above recommend proper repair, but I sealed the timing cover in place using UltraGray Permatex after cleaning area with carburetor cleaner then 100% isopropanol (e.g. IsoDry gas line anti-freeze). Also replaced the water pump. So far no leaks from cover. There are special alloy rods used with propane torch that allow you to patch aluminum if you remove the timing cover and thoroughly clean it. Youtube has videos if you search on "aluminum brazing with propane torch".
It's just a slit. I was considering JB Weld, but unsure about it after all the replacement recommendations. I'll probably try it.I'd be tempted to let it drain down overnight clean it really well, alcohol clean, then use JB Weld on it. There's no pressure there, so if you can get it clean, it should work.
Is it just a narrow slit or a big gouge?
Oil doesn't seem to bother it. Gasoline does, and it seems coolant does. I tried using it to repair a couple thermostat housings and in both cases it turned to mush. Peeled off the housing and I found goo floating in the reservoir. Personally, I don't think I would try it again.I dunno that it melts.... maybe it's the liquid interaction though.
