DanMi Posted July 18, 2017 Report Share Posted July 18, 2017 Hi all I have just rebuilt my mk2 spitfire's 1147cc engine after being in the garage for 25 years (car was a 1500) the head was converted to unleaded and lightly skimmed. Now I find oil leaking from the pushrod tubes. Is there any way to fix this, preferably without stripping the head back off. I can't really tell if the leak is top or bottom.

Pete Lewis Posted July 18, 2017 Report Share Posted July 18, 2017 some work to dribble brush somthing like loctite 574 or similar will seap into the tube clearance and goes solid when air is excluded, once the seeped in has set wipe of any excess never tried this but these types of product work very well there is no on car mechanical after the event fix that ive ever come across await more clues pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted July 18, 2017 Report Share Posted July 18, 2017 Get a tapered socket that fits into the end of the tube and hammer it lightly down into the tube; this will spread the flared end and helps reseal it. Can only be done properly though if head is off and you can access both ends.... Link to comment Share on other sites More sharing options...
DanMi Posted July 18, 2017 Author Report Share Posted July 18, 2017 I can at least get at the top and will try the Loctite and a hammerring Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 19, 2017 Report Share Posted July 19, 2017 dont get the socket stuck !!! you can with a fiddle jack the tubes out with a large expanding rawl bolt never tried but have seen it done years ago. can also be used to lift followers if there's room to extract them . then fit new tubes only to find they still leak Link to comment Share on other sites More sharing options...
DanMi Posted July 19, 2017 Author Report Share Posted July 19, 2017 To be honest. I just put the engine together so taking the head off is not too serious particularly if I wait till winter when I don't use the car. I will try the above first and have a chat with the shop that did the head work. Only problem with head off is that I used my new old stock head gasket and probably won't find another and I don't think Payen do am 1147 one.
