[TR] Timing case oil leak

[Robert Rochlin]

I also had a deformation in the front engine plate which caused the timing chain cover to leak.  I used “Right Stuff” to seal the timing chain cover to the engine front plate. I’ve used Hylomar extensively, but the deformation required filling a deformation gap and “Right Stuff” excelled at that, sealing my timing chain cover perfectly. I have been told hat Right Stuff is a bear to remove, but so far I’ve had no need to to do that.
	Best,
