Title: Resealing oil pan and timing cover
Post by: F14CRAZY on April 29, 2015, 09:09:16 AM: Well I fortunately got my oil/water pump to stop leaking. Yay.

I probably should done it while I was messing with the pump but it seems that the timing chain cover and oil pan are also seeping. I don't know if those are the technical brick terms but I think you guys understand the parts I'm talking about.

I'm thinking about removing them and applying new RTV when I do my next engine oil change. Is there anything special I need to keep in mind? Anything to replace while I'm in there?

I think I've heard about timing chain sliders becoming worn...are the sliders, chain, or sprockets a wear item that I should inspect?

Anything else?

I felt your pain in your other thread. So, what were the final steps taken to resolve the issue?

Post by: F14CRAZY on April 29, 2015, 10:21:29 AM: I took the cheapest and easiest way out and installed a used K1200LT pump from ebay. Just make sure to get the other little oil pump gear that goes in the block due to the lower teeth count (in case anyone searches for this in the future, or if you're curious). I just wanted to get it back on the road. I saved my old pump in case I decide to eventually rebuild that. I think the issue was the pits tearing up the inner blue sealant of the new seal.

Will check the oil sump screen

Any more an you might strip out the threads. IF you have an oil drip, its probably not your gasket leaking, but the little rubber dinguses on the shoulder bolts. If they get old and hard, they don't transmit the correct squeeze pressure to keep the timing cover sealed. I need to replace them on the Stormtrooper, it leaves a few drops on the floor after a few days. I'll try to find you a part number sometime today, I need them anyway.

It's more a sh!t -- don't want to have to do this twice thing. They're cheap. Skip lunch one day and get new ones.

Don't ask me how I know this. New gaskets might also be a good investment -- there's nothing worse than sealing those covers up and having to drain, pull and redo the whole thing. Well, there are worse things -- your recent thing with the water pump comes to mind. I admire your tenacity -- really, I do.

I did this on my K100 a few weeks ago. Not that bad a job.
I used ultra grey to seal the pan.

Post by: Idonthaveaclue on November 02, 2019, 12:33:53 PM: Super old thread, but the closest I could find on my question.

I'm planning on re-sealing the timing cover. I was told that it holds the timing? I didn't see anything in the workshop manual about it?

Also I was told that the Timing cover is sealed with RTV. Is there a special kind?

Thx

If using 3-Bond instead its best to hand tighten bolts and let sit overnight to cure before final tightening

Thanks for the reply.

Does the cover hold timing, or can I pull it off and not worry about that? (very new mechanic type here)

Thx

No, it covers timing. :-)
