tbomb New Member 19 Member For: 9y 5m 4d Posted 15/09/15 04:29 AM Author Share Posted 15/09/15 04:29 AM Appreciate the help guys . Engine oil is at normal levels there has been rattling coming from the cat which I will be looking into this afternoon could possible be a blockage but strange that it was instantaneous after coils, sparks, service ect I'm hoping for simple solution Link to comment Share on other sites More sharing options...

tbomb New Member 19 Member For: 9y 5m 4d Posted 15/09/15 08:53 PM Author Share Posted 15/09/15 08:53 PM Flutter out the wastegate has become very quite aswell. Also taking and extra 1000 or so revs from normal to even start winding up and boost is very minimal. from the checks last night turbo spins smoothly with no unusual sound once winding down.spins freely with no movement on turbine or noise, no signs of rubbing or warn blades. All bolts also seem to be in order. Pipeing is all aftermarket and doesn't cross the top of the engine so to remove the cover to reach Sparks and coils no pipes are disrupted or disconnected . Exhausts was checked just by removing the 02 sensor on dump pipe with no change, this afternoon I will remove exhaust before the cat and hope for the best .

tbomb New Member 19 Member For: 9y 5m 4d Posted 16/09/15 08:25 PM Author Share Posted 16/09/15 08:25 PM Took the exhaust off from infront of the cat with no real change in performance did notice aswell a wire/ sensor behind the engine on the exhaust side that has completely melted. I wouldn't have any idea what it's for but seems to be connected to or runs with the wires connected to the coils. Will have a closer look after work Link to comment Share on other sites More sharing options...

If that's cooked your VCT won't be working and it will cause the engine to produce less power.Also +2 internet points for returning and updating what you found. 3 Link to comment Share on other sites More sharing options...
