Timing chain tensioner seal replacement

[BL92]

Not a good idea using the thread sealer, the oil input is before the threads, waste of time, I am changing the oil again right now asap








I am guessing it's seized or something, and over pressurising,?? I have ordered a new 1 anyway, INA from Greshm









The UK Forums, They suggest one of these seals

You've definitely got the best access to this that you'll ever have with the engine out of the car, so I would replace it. Undo the tensioner, make sure the sealing surfaces are nice (I usually run some red scotchbrite over them), replace the crush washer and reinstall.



Nah, should be fine to reuse. But make sure you follow the reuse instructions:

Well.. I feel like a dummy: for some reason I had remembered reading that the right thing to do when re-installing the TCT was to "prime" it by completely compressing it while submerged in oil, and allowing it to decompress and take oil in. I don't remember where I read this or why it had stuck in my head as correct.

I recently re-timed my engine, and performed this incorrect procedure that fills the TCT with oil rather than purges it of oil as described in the correct instructions.

Question is: how bad is this? Why does the oil need to be pushed out before reuse to begin with, isn't it just going to refill with oil during operation?

Do I need to remove my TCT and re-do this with the correct procedure?
