Question time
Question time
They might seem obvious but just want clarification really
1, when i start my car in the morning i get a puff of blue smoke from the exhaust, in my previous experience this is the start of the valve stem seals going but wanted someone who knew more to clarify. Only engine mod is a cat back exhaust.
2, when the car is cold and i pull away it judders unless i rev it above 3k rpm guessing its the flywheel thats the issue but is this a known fault or anything anyone has had experience of?
3, i did have another question but mind has gone blank right this second so will add it later
Thanks in advance for any help given

Rather than start 3 seperate threads i thought i would just do one with all my questions....

Service history is upto date but its on 108k now so could be worth a look at the plugs will pull one to see what its like.
If it were a coil pack wouldnt i get a misfire at higher rpm?

21-01-2019, 06:12 AM #6The clutch juddering is quite a common issue, and IIRC it's because the springs are starting to wear out in the dual mass flywheel so the outer section of the flywheel is sort of bouncing back and forth trying to play catch up with the inner section. That can be fixed either by getting it welded solid, or replacing with a solid flywheel. (not many people bother fitting a new dual mass one as they are expensive, and it could happen again)

reco2k Finally remembered the last questiob, i just got an engine stand to rebuild my v8 and it may sound stupid but how do i attach the engine to the stand??? Lol
Ross
In theory, using the bolts that the gearbox bellhousing attaches to the block with. In practice these may not be long enough, as the holes in the engine stand are probably thicker than the holes in the bellhousing.
I bought 4 100mm high tensile bolts for mine in the end. It was a right pain in the **** finding some fine pitched bolts (Toyota love using 1.25 thread pitch on HUGE bolts) that were long enough, think I got them from http://www.namrick.co.uk in the end.
