Fish13 Posted May 24, 2006 Share Posted May 24, 2006 Hi, (3.5 EFI) Noticed I had oil seeping out of both rocker gaskets. Checked the bolts and they'd all worked loose. Just for safety's sake, fitted new gaskets and put thread seal on the bolts. Short test run and the bolts had worked loose again (re tightened and they seem okay) but now oil is coming out of the small PCV air intake valve at the back of the nearside rocker cover? Took it off and cleaned it out and made sure the hole wasn't blocked up etc. Oil dripping onto exhaust.....lots of smoke....worried looks......etc. Why???? Help...

DEANO3528 Posted May 25, 2006 Share Posted May 25, 2006 Sounds like the engine is pressurising. If all the breathers are clear it might be worth a compression test. All should be within 10% of each other and ideally no lower than 135 psi Quote Link to comment Share on other sites More sharing options...
Fish13 Posted May 25, 2006 Author Share Posted May 25, 2006 Hi Deano, Many thanks for the reply. I took off and cleaned out the two breathers on the rockers, so I know they are clear. What causes the engine to pressurise? The cylinder head gaskets were done about 6 months ago if that makes any difference. Quote Link to comment Share on other sites More sharing options...
Fish13 Posted May 25, 2006 Author Share Posted May 25, 2006 Have since been told to clean out the tube on the plenum that the hose from the flame trap joins on to. I noticed mine was full of gunk, will give it a go and keep you posted. Cheers, Fish. Quote Link to comment Share on other sites More sharing options...
Fish13 Posted May 25, 2006 Author Share Posted May 25, 2006 Tube in the plenum that the flame trap pipe joins on to was rock solid with cr*p! Cleaned it out and engine runs a LOT nicer and smoother and doesn't spray oil out of everywhere! Phew.... Quote Link to comment Share on other sites More sharing options...

Fish13 Posted May 25, 2006 Author Share Posted May 25, 2006 Hi Geoff, Yep, was panicking there a little I'll admit! Had been a really sweet engine up until then! All better now. 'Till the next thing of course.... Quote Link to comment Share on other sites More sharing options...
