Hey all,
After adjusting valve clearances and replacing tappet covers one of them broke with barely any applied torque.
It broke similar to the ones in the pictures however all of the threads are intact. It broke above the final thread and quite cleanly. Those pictures are not mine! Just googled some examples and found 'em.
I've jb weld-ed it and I'm waiting for it to cure, in the meantime I've ordered a new tappet cover (delivery in 4-8 days but over the border who knows!).
Anyway, will it hold up inside the cylinder head for a week or two until the new one arrives? I only put on 50-75 km's a day, mostly short commuting and some short stints on the highway.
My main concern is the minimal amount of weld in there melting and dripping down into the engine. I'm entirely unfamiliar with this stuff so I'm hesitant to actually run with it. However it holds to ~600F and I cant imagine my engine gets remotely that hot..
At the least: I have a motorcycle test to go to this friday, so hopefully it would work just for that? Around an hour of city riding?
Thanks!
P.S. yeah I'd rather not use jb weld but with no other form of transportation than the bus I want to feel confident before taking the bike out in this condition.
