My Golf is smokey under high reving , and I mean REALLY smokey...enough to make my car dissapear behind a cloud of white smoke. Theres oil leaking from the rocker cover, dripping down the right side of the engine block. Also it runs really hot...the needle is like 3 quaters or slighty more along the temp. gauge. Also if you dab the accelerator at idle so it revs to 2000rpm then let it drop off, it decides to revs by itself for a couple of seconds. I've adjusted the idle screw and I've made it slightly better but can't fix it completely. What could it be? Rocker gasket? Head gasket? Valve stem seals? I've heard them all mentioned but nobody really knows. If I brought a gasket kit would it contain all these? Are they expensive for garages to fit or could I fit it myself? Thanks PS...plz help want it running proper so I can get it rolling road tuned. Edited by: Black-Mk2-GTI
Lots of different bit wrong.... if you stab the pedal with a digi then it'll do what you say yours does, gets on my tits as it means it's a whole lot dofferent to heel and toe then the other cars we have but there you go. with I could stop it. The smoke at high revs could be caused by pressure blowing by the piston rings and pushing oil vapour out of the breathers in the head back in to the induction system, this could also be happening if the valve stem seals are shot too, my money is on stem seals but you can swap them really easily if you have a saturday free a torque wrench and valve srping compressor plus a gasket set of course, nice quality BTW as they will contain most of the seals you need including the rocker gasket which will stop that leak if you dont overtighten it as lots of monkey garages seem to.... get head bolts too. the over heating (well running hot) could be caused by a few things, firstly I'd swap the thermostat as its cheap and easy to do. But check the one you fit is opening at the right temp by boiling it in a pan of water on the stove with a thermometer in there to tell what temp it opens at. Less comon is a blockage in the rad or an air lock, but you'll get rid of that while changing the stat and flushing the system (after the head job of course) Last on the list for possible causes of over heating is using seroiusly low grade fuel, ignition badly retarded or the water pump is proper fuct due to cavitation on the impellor (doubtfull but have had it happen) -ed. for stupidity and spelling- Edited by: jake
oh yeah, while the rocker cover is off, soak it in summat to get the crud out of the oil seperator gauze in the top, Years ago with one of our old cars this got gradually filled with oil and blew its contents down the carbs causing the person in the following car to nearly crash (me following Pa as it happened ) if the stem seals dont cure it then it''ll probvably be the rings and that is all the excuses you need to get a 2.0 block and use the head you have already!
Like jake has said.ive cured a few smokey 8vs by cleaning out the rocker cover and breather pipes.give it a try
Thanks for the info...I've been told by my old man a while back that it's most probably the valve stem seals so I think maybe I should go for that as the problem. I only have a basic tool set with small ratchet and a few spanners so I dont think I could do whats needed. Im worried about dodgy mechanics buggering it up though would taking it to a place who tunes cars and does performance bits be a better option? I could get it rolling road tuned after then which I would like. Also is a 2.0 bottem end easy to get away with insurance wise? In other words is it possible to pretend the engine is still a 1.8? Im only 20 and I havent even got this car insured yet and dont want a bigger quote from what Ive been getting so far
How many miles has the engine done??? Sounds like its rings if it smokes at high RPM (the rings begin to resonate in the bores allowing blow-by) When the car burns oil (especially a lot) as yours sounds like it is, it lowers the octane of the fuel, thus making the car run hotter too..... If this is the case, then the bottom end is goosed! It either needs rebuilding or go for a tall block 2L from a mk3 (2E,AGG etc) As for your idle problem, you need to adjust the idle PROPERLY. Its not just a case of tweaking the idle screw!! Look for the guide to setting a digi idle in FAQ's. Remember to check all the throttle microswitch wiring & for air leaks first.!
If the smoke is mainly on acceleration/pulling away then I think this points to stem seals. If it smokes all the time I think this points to rings/pistons.
It runs fine apart from the VERY bad 'clouds' of smoke on hard acceleration...It's quite comical because it's like a secret gadget out of James Bond!
Could still help though. Better to revive an old thread than to start a new one and rehash all the same information.
any ideas anyone ,mk2 8v gti wen warm an under load its blows blue smoke ,i kno this is a sign of ring wear but it doesent do it all the time ,just been out in it an it started smoking under load ,parked up an was still smoking heavily ,went out again no smoke an wen stationery ,revving engine ,no smoke ,cars done 96 thousand miles ,could it be valve stem seals .i did replace these a few years ago but im thinking one of them didnt seat properly ,i may be wrong ,any help would be appreciated
Surely if a valve seal was leaking it would leak all the time and smoke..all the time. Have you fitted a new pcv valve on the rocker cover?
ive got a new one to fit but wen i blew through it its exactly the same as the one on the car so didnt fit it
