Has anyone else had the dreaded blue smoke and if so was it the piston rings.
I've had the blue smoke but only on startup or when pulling away after idling at a junction. It was stem seals and when I removed the collets from one of the no-3 cylinder intake valves it just dropped out - the seal didn't hold it at all. This was a totally unsealing seal and it allowed oil to build up on the top of the intake valve and it got sucked in when I accelerated. Even with it letting oil through badly there wasn't any noticable blue smoke while idling or when moving. In the summer there was a big, thick cloud when I pulled away afer sitting at a junction for a while.
Your trace of smoke doesn't sound like that to me. The plug in no-3 cylinder did get oiled up regularly so it was obvious which cylinder it was.
I think you said that you didn't have much smoke and it wasn't all of the time. If the oil hasn't been changed regulary you could just have a sticky piston ring or they could have just lined the gap up in all of them for a while. It might be worth a Forte oil flush in it for a while before doing anything drastic just to see if it helps.
Cheers for the Advice rpont.
*update time* On friday I thought I would ring the garage thats has had dealings with my car for the best part of 3yrs, the garage owner I have known for longer and so I gave him a ring and he said bring it over and we will have a look, he told me there is blue smoke but its not excessive and that they knew about it and that its not excessive and not a failure, anyway they put it on there emmisions tester and funnily enough it passed no problem.
So advice from the second garage was to go back to the original garage and get an appeal form the garage is well known for cowboy antics and so when I got there asked for a form which they skirted around and they did the retest there and then and guess what it passed again.
The original garage when testing was over revving the engine which is all wrong I was told it should have the revs set at 2.5k - 3k and no higher where as the original garage had it revving between 3-5k so be careful folks I got caught out but it all came good in the end as far as the MOT is concerned.
I now have my MOT for my car which is a good thing.
Now back to the issue the blue smoke, I have been regularly checking my oil each time I have been going out and it does not appear to be losing any great amounts at all if any. (since the oil/filter change)
I have mentioned before and I maybe clutching at straws but I know my rocker cover is leaking at the front and I also know the manifold seal may not be the best as I have still got to sort out a couple of duff studs.
When I checked the car this morning oil etc you can visibly see oil has run down the side of the thermostat housing and run onto the exhaust manifold I am now thinking oil is seeping in through the join and into the exhaust causing the blue smoke.
My next port of call I plan to remove the exhaust manifold and have a look to see what is going on whether this is my problem as I maybe lucky.
The garage where the car usually goes mentioned it could be the Headgasket on its way out and so am thinking to get it pressure tested can any suggest prices or a recommended tool to carry out a DIY pressure test.
If I find the car is losing pressure then I guess I shall see about getting the job done, I have had a quote for about £600 private garage and they know there stuff but all the same I will probably do it myself.
