69' Bonnie oil leak

Tim_S · Jun 12, 2015

Upon start up I suppose when the crankcase pressure is highest I get oil seeping out the bottom of the push rod tubes. Do I need to pull the head completely off or can I just loosen everything up and pop in the seals?
This is my first attempt with playing with a triumph ......TIA

The head must come off.

Well, at least it's a reasonably straightforward job.

Factory manual and '69 parts book-if you need them?

Ensure you get the proper "crush" height before you go torquing down he head, this will vary depending on the type of head gasket you're employing.

All excellent advice above. What more could a guy want?

he could want the bodger suggestion!

at times i just wasnt into pushrod tubes or didnt have the time. . . ive had reasonable success for a while gooping silicone seal onto tbe outside. clean super good first.

dont use orange hi temp or everybody will know how lazy you are

The crush is critical!
