SolihullBeast Posted June 17, 2010 Share Posted June 17, 2010 Just a quick questions regarding a 96 300tdi Disco, the vehicle actually belongs to my father, who assumes foolishly that I am a knowledgeable about land rovers based on the amount of time that I spend under the bonnet of mine!! So when his vehicle decided to give up the ghost on the M25- after its recovery back to the farm I was his first port of call, but it completely stumped me, the symptoms are as follows - A trail of oil form the oil filler cap down the engine plastic trim, looks like it had been flowing pretty heavily at one point. - Oil seeping out most sides of the rocker cover gasket. - Blue Exhaust Smoke. - Blue smoke coming out the engine bay, from somewhere under the exhaust manifold, I can't pinpoint where. - Major Loss of power Prior to the journey he said the oil was slightly above the max(he did not mess with the oil level, just left it) I don't know what the problem is but here what I guessed; There must be pressure for the oil to have been forced out the top of the engine, The blue smoke means oil is being burnt, and low power means the fuel/air mixture has been contaminated with oil? So I made a wild and rash guess and told him it may be a piston ring. I'm sure that the answer is probably fairly simple- but advice would be great so I can give him some more info- he hasn't been lucky with this land rover(new gearbox, two clutches, new transfer box, starter motor, steering box... its almost a new vehicle!) Many Thanks Sam Quote Link to comment Share on other sites More sharing options...
Les Henson Posted June 17, 2010 Share Posted June 17, 2010 Head gasket from one pot to the camshaft cavity. This put pressure into the sump - causing oil to be pushed wherever possible. Les. Quote Link to comment Share on other sites More sharing options...
tweetyduck Posted June 17, 2010 Share Posted June 17, 2010 now thats experience or knowledge. Either way, impressed i am ! Noted for my trip and praying it never happens to me. I will be carrying a spare head gasket. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted June 17, 2010 Share Posted June 17, 2010 Take the oil filler cap off and start the engine - if there's a strong pulse of air/smoke/dieselly smell from it, then the head gasket is likeley. Les. Quote Link to comment Share on other sites More sharing options...
SolihullBeast Posted June 17, 2010 Author Share Posted June 17, 2010 Oil filler cap off, no air, no smoke and no smell! just blue smoke that appear to be rising from the front of the engine, if it is a head gasket what is the cost of parts roughly if I do the labour myself?

landkeeper Posted June 17, 2010 Share Posted June 17, 2010 hows the oil level now ?? take the dipstick out and watch the top of the tube for smoke Quote Link to comment Share on other sites More sharing options...
simonr Posted June 17, 2010 Share Posted June 17, 2010 Could the smoke just be oil dripping on the exhaust manifold? You said it gave up on the M25 - can you say what about it gave up the ghost? What were the symptoms before during and after? Si Quote Link to comment Share on other sites More sharing options...
