Title: Billowing exhaust smoke after V6 spark plug change
Post by: 24_Valve on 08 April 2010, 23:02:50
Just finished fitting new plugs (Champion twin electrode RC10DMC) on my 2.5 V6 mig  :y after major hassle accessing passenger side plugs.  Got down to working on the much easier driver side plugs and found loads of oil in each spark plug well (no oil in driver side plug wells)   :(  Tried to soak up most of the oil in each well (paper towel & screw driver) before removing each plug... but each plug came out covered in oil & residual oil definately dripped into combustion chambers.  Fitted new plugs & reasembled everything.  Started her up & white smoke billowed from the exhaust so much that I was expecting neighbours to call the fire brigade  :o Took my mig for a 5 mile run & its all settled down.  I'm assuming the oil is from blown cam rocker cover gasket & not too worried and guess the smoke storm was just oil burning off.  What I don't know, is how much damage I've done to my shiny new plugs by burning oil  :-/ ?  Will this foul the new plugs & if so have all my efforts to fit new plugs, been in vain  :'( ?  any advice welcome, cheers steve. ps. GM seem to have made it virtually impossible to the access rear passenger side plug with an ordinary extension bar, removed wipers & scuttle but still took me ages!?

The plugs will be fine, but the cam cover gaskets need doing ASAP. Clean the breathers out too. :y

Thanks Kevin. Thats music to my ears because it took me the most part of the day do complete the job! I have to do all the work on a public road with limited tools. I live in flats with no lift so if I forget a single thing I have to put everything away, secure the car and take a long hike. I will have to get the gaskets done but local vox dealer has quoted £75 for GM gaskets (pair) and local garages in my area of London charge upward of £50 an hour labour.  I'm a London paramedic (13 yrs) on long term sick pay (peanuts) and not that experienced working on cars, just people  ;) I reckon the strip down to access the gaskets and re-assembly is beyond my scope & tool kit  ::) so I'm holding out for now and just topping up with 15w/40

An easyer way to get the oil out of the plug wells is by useing a ceringe (thing for injections) that you get for refilling your printer cartriges, just put a straw from a lube spray can on the end, works great and you get nearly all the oil out.

Sorry about the spelling its not my strong point.

Thanks Razzo (have just sent you a pm) really appreciate the offer  :) Thanks for your offer too Smooth but won't be in NI until July (mates wedding  ;)). I wish I'd had the savvy to think of using a syringe and red lube thingy but too late now cos its all back together and the oil got in. But thanks anyway ghost rider, I definately won't make the same mistake again  :y

Lol, if the plug wells had oil in them then when changing the plugs it will have got into the pots.....this will then burn off with nice big fat clouds of smoke!

Massive thanks to 'Razzo' for replacing the rocker gaskets on my V6 totally professional job 100 times better than any garage mechanic! My lovely mig is now running like new, with breather system blasted clean with an air compressor, new 'O'rings, seals & OE gaskets. Couldn't be happier, TOP Bloke!  :y
