my 1993 8v gti 2e has started smoking badly from the exhaust, the hotter the engine gets the more smokey it gets, its greyish smoke and smells quite strong. any advice would be appreciated! thanks.
-
If its burning oil it could be valve seals or Rings.
Or it could be the head....
Does it over heat?
Is the oil/water full of Mayo?
Does it run ok?
Does it sound tappety?
:smiley:
-
no it doesnt overheat
it drives like normal
theres no mayo in the oil
it been a little tappety for years and is no worse now than before
-
Im on valve seals then :wink:
-
thanks mate, is it a big job, what should i be looking to pay for the job to be done at my local mechanics?
-
That's just my guess, you need to check things like compression/cooling etc to be sure on the fault.
At a garage if you supplied a recon head and all the bits you are looking at around £200, and £200 in parts.
A good engine could be had for around £200 and a bit more to fit :smiley:

Grey smoke is mixture / not running right, oil being burnt is blue so do the basics like check air filter and plugs,

Really the op needs to tell us what it smells of, also given it runs well I would not jump to mixture being the fault.
I stand to be corrected though, maybe a picture of the smoke would help in diagnosis :smiley:

Indeed but smoke does not always mean oil being burnt even more so when it is grey.
-
Quite right, grey/white smoke can indicate head faults or major overfueling but the op said it was running ok.
The pitfalls of internet diagnosis..........

took the car to local mechanic this morning, went back after couple of hours and they say it needs valve stem seals, they suggest fitting a head kit ( head gasket, stem seals and rocker box gasket ) £300?
-
That seems pritty good....
That cover everything thou? Like a new timing belt and head skim?
-
yes the price of £300 covers everything, head gasket, head skim, valve seals, rocker cover gasket and new timing belt, so not a bad price then?
-
Id be happy with that :smiley:
-
i had the valve stem seals replaced and the head gasket complete with head skim and rocker cover gasket, when i went to pick it up the mechanic said 'it was still smoking when i took it for a test drive, but it cleared after a short while' he said he had taken it for an emissions test and the emissions were very low and looked really good. ive driven it over the weekend and it is not as smokey as it was and it doesnt smell of burnt oil anymore but when revving it, it does sometimes give off quite a cloud of whitish smoke. is this normal for a 150000 mile 8v or is it not sorted? any thoughts?
drives ok.
no codes on my vag scanner either.
-
Is the whiteish smoke more like steam ,keep an eye on your water level,remember though, cold weather and hot exhaust emissions do produce what looks like clouds of smoke especially whilst stationary.
-
will keep an eye on the water level, you could be right, i might be looking too closely for exhaust smoke and its was very cold here yesterday when i was checking out the exhaust, does the fact that the emissions are very low mean that it cant be burning much in the way of oil or over fuelling?
-
i decided to take my car for an emissions test despite the fact that the garage that did the stem seals saying that they took it for emissions test and they said it passed.
IT FAILED!
can anyone give an opinion of these results please?
engine was fully warmed up.
FAST IDLE TEST (2450-2850rpm)
CO limit 0.3% actual 0.503% FAIL
HC limit 200ppm actual 98 ppm PASS
lambda 0.970-1.030 actual 1.058 FAIL
2ND FAST IDLE (2450-2850rpm)
CO limit 0.3% actual 0.545% FAIL
HC limit 200ppm actual 97ppm PASS
lambda 0.970-1.030 actual 1.051 FAIL
NATURAL IDLE (720-920rpm)
CO limit 0.5% actual 0.478% PASS
went back to the garage who did the stem seals and showed him the emissions printout and after looking at the results he said 'i only did the natural idle test' looks like your cat has been damaged by the burning oil! ? The exhaust still smells a litttle oily to me! He said its fine for a 150000 mile car. MOT at the end of may so i have a little time to sort it out, can a cat be cleaned of oil or IF it is the cat is it ruined? does cat cleaner actually work?
-
I'm not 100% sure but im quite certain the cat can't be 'cleaned'.
Id just leave it until the MOT and replace the cat. Then (If you would want a decat) gut you'r original cat, Re-install and then you have yourself a stealth cat.
-
Not a good idea to "degut" cat yourself!
