Bad signs? (time for rebuild)

[Ian@TunerUK]

Car idles rough from cold, turbo boost doesn\'t stay constant on idle until warm. When cold and I put it in gear the revs drop right down to nearly cutting down. White smoke on start up...

And I going to have to dig deep?

[Jit]

how long is the white smoke on startup...if its a fair while, then it sounds like poss coolant seal failure
Although a fluctuating vaccuum reading on idle is normally a bad sign....does it start on both rotors?

It\'s there for a bit, few mins maybe?

How can you tell if it\'s starting on both rotors? Still sounds the same once started (obviously apart from rough idle)

[Jit]

one rotor will catch, and itll sound rough for a moment, and then the second will start....
only one way to find out if its rebuild time or not.....get it comp tested and get the coolant system pressure tested...i think id be right in saying WGT is closest to you

[Ian@TunerUK]

Yeah WGT ain\'t too far away, think I\'ll have to get up there and get it checked out!

Balls! lol

The boost gauge will fluctuate on idle if the revs fluctuate though - and that isn\'t necassarily a sign of a broken apex seal.

[Ian@TunerUK]

Just a thought, the alternator belt needs changing, it\'s squeeking a bit and I have a new one on it\'s way, would this affect anything I\'ve said?

[G@NDY]

^ Im afraid I dont think the belt would cause that, hope im wrong tho.:confused:

[Ian@TunerUK]

It was a stab in the dark to be honest, no harm in trying it though

[Jit]

an alterantor belt done up too tight could accelerate bearing wear....but not cause any of the probs above

[LeedsLad]

balls !! this sounds like my car only the revs dont drop down that much when its in gear, and no boost guage to check.

Are your coolant levels stable? Note the level on the dipstick in the overflow tank when the engine is cold. Take it for a run up to normal temperature, then let it cool overnight. Check the level again when cold. If the level is the same, chances are you\'re ok. If the level increases then coolant is not being drawn back into the engine under vacuum and it\'s very likely you\'ve got imminent problems. Hope that helps

Dont sound too good Ian,

Check all your hose attachments just incase there a hole somewhere and you are losing vaccum, although it does sound like it might be time for rebuild.

Whats the mileage ? i know yours is a twin turbo setup more or less standard engine right ?

Yeah standard bar filters and exhaust. rebuilt approx 30/35k miles ago by WGT.

Will check the coolant thing this weekend thanks :cheers

Hmmm alittle early for engine wear already on standard internals but wonder if it was a standard rebuild rather than full ?? as 35K isnt the norm on a standard engine, however has been heard of so not out of the question completely.

Have a good look around it at the weekend and do the coolant thing and see what we got, i have a family function tomorrow otherwise would have popped over to see you as only down the road,
