adam_christie 0 Posted October 1, 2007 Report Share Posted October 1, 2007 Bloody hell. Hmm. Have you got any knocking noises coming from the engine? First impressions suggest that something piston related is going / gone. Is there a clinking coming from the engine suggesting a broken piston ring? Link to post Share on other sites
Dub-Donna 0 Posted October 1, 2007 Report Share Posted October 1, 2007 Sounds like piston rings to me. Oil leaking into the chamber and burning up.Your new cat will not last long trying to clean it either.Is there any oil on any of your plugs when you take them out ?Mark.

Guest shane6047 Posted October 2, 2007 Report Share Posted October 2, 2007 Hello Mark,Funny you should say that as when i got the car i had a full service done and within a month the spark plugs needed changing again as one had cooked itself.........So what would you suggest i do?Also to adam,There's only a clinking noise when i start her, i thought it was the timing chain coming slightly loose but now you've said that i dont know.....To you both,The car is driving fine apart from a slight lose in power and obviously the smoke, the car has done a whopping 170,000 miles and this is the first magor problem she's had, i will say thou she has had a hard life, it's gone throu 3 people since new and there all my mates but i know they drove it hard.What do both of you suggest i do from here?

drue1 0 Posted October 2, 2007 Report Share Posted October 2, 2007 your looking at a engine rebuild matey.but what sort of price i dont know some times its cheaper to get a second hand lump and stick it in.and if you go that route get the clutch replaced and timing chain as well then it saves you money in the long run Link to post Share on other sites
mannie 0 Posted October 2, 2007 Report Share Posted October 2, 2007 I would guess your valve seals /valve guides are shot,and oil are suck through the guides .are your plugs wet ,you using the right plugs ? Link to post Share on other sites

Oil will only get sucked through the guides / seals when there's substantial negative pressure in the inlet manifold, I.E. when coming off throttle with the clutch still engaged - Engine wants air, TB's cut it off, engine sucks it through other openings like gaps in worn guides etc etc etc etc!
