GazaGt6 Posted October 7, 2010 Share Posted October 7, 2010 Hi guys,As some of you may remember, i had oil being pushed through the top of the rocker box. Now i have the top end sealed and there doesn't seem to be any oil (I just hope that i havent done a very good job of hiding a big problem ;D). however on a test run, the dreading smell of buring oil came back, and on inspection, oil had seeped through between the head and the block on dizzy side. Faulty gasket? warped head/block!? head was skimmed before being fitted this spring, so cant see it being that. Would it be worth taking head of, inspecting, replace head gasket and torque it down again? :oThoughts?regardsGarry Link to comment Share on other sites More sharing options...
thescrapman Posted October 7, 2010 Share Posted October 7, 2010 I would retorque the head first, loosen and tighten in turn, easier and cheaper!You may have as I did a recessed bore gasket on a non-recessed block.After a few hundred miles it started leaking like the Amoco Cadiz. Had clearly held for many years for it's previous owner, but the 15-odd year period of inactivity was too much for it.CheersColin Link to comment Share on other sites More sharing options...
GT6 M Posted October 7, 2010 Share Posted October 7, 2010 Gaz, you said you had oil blowing out, so by sealing it all up, you will be creating crank case pressureyou really need a biggger vent for the engine, cos a normal engine has about 2-4 cfm blowing past the rings at tickover, so think what it be like at revshave a look at the majority of our cars after a run at high revs, all covered in oil,!!basicly the hole in a 4 cyl 1300, is no that much bigger than the vent hole in a 2-2.5 engineso as you can see, press will build up.Failing that, maybe a rebore is in order, or some of that stuff Mr Chatterton /Nik have been using,!!!rgds marcus Link to comment Share on other sites More sharing options...
GazaGt6 Posted October 7, 2010 Author Share Posted October 7, 2010 Ahh is the cylinder wall repairing magic juice?? 8)!! I tell you what i have noticed, on tick over there is a knocking sound, higher the revs, the tempo of the knocking increasing (obviously). cant make the link, could be anything i suppose.

TimW Posted October 7, 2010 Share Posted October 7, 2010 sounds like you have just moved the problem of the high crankcase pressure from the rocker cover to the head/block joint. Did you do a compression test??PS: well done for sealing the rocker cover. You must have done a grand job! ;) 8) Link to comment Share on other sites More sharing options...
GazaGt6 Posted October 8, 2010 Author Share Posted October 8, 2010 yeah this is what i assumed. when i did compression test they were all consistent (very low though) Link to comment Share on other sites More sharing options...
