Jamie-GlanzaV Posted October 24, 2014 Share Posted October 24, 2014 Need some help to narrow down what has went wrong and what my options are. Bought the car 2 weeks ago it's a 98 V it was fine for a week with no thrashing etc, then all of a sudden it started spitting oil out of the Bov and then started smoking heavily from the exhaust. I parked it up and took it out during the week for five mins just to see if I could find out what it was. Symptoms; No smoke on start up gradually turning into slight smoke.Smoking heavily under any throttle from exhaust and from engine bay.Smoke seems to be blue then to turn into white smoke.Spitting oil from Bov.No or little smoke on overrun.Oil residue in breather pipe.When car warms up a bit you can hear a clonking noise from the engine if you listen closely.Initially thought it was turbo seals because of oil in Bov but don't understand this because rest of the symptoms suspect engine failure, rings, seals, head gasket etc I'm not great mechanically lol!Also what's my best option thinking of just dropping another engine straight in as I need the car for daily use.Any help is greatly appreciated !

mikey4410 Posted October 24, 2014 Share Posted October 24, 2014 Do a compression test to makesure engines ok. But at a guess I would say turbos let go. Quote Link to post Share on other sites
AdamB Posted October 24, 2014 Share Posted October 24, 2014 Pull the intake off the compressor housing and the cat/decat off the turbine side and check in there for oil. Does sound like turbo. Quote Link to post Share on other sites
Jamie-GlanzaV Posted November 25, 2014 Author Share Posted November 25, 2014 Just an update on this changed the turbo and same problem so done a compression test 175 equal across 1,2 and 3 however 4 was 45 which is really low? Could have melted a piston itself? Will be opened up tommorw if bore and all is fine will be rebuild but if not I can get a low milage replacement engine and sell mine for some money back to same person.

Stu Posted November 26, 2014 Share Posted November 26, 2014 Bugger - sounds like #4 isn't happy, possibly a ring land? Take the cam cover off and double check the valves are doing what they should but its unlikely thats the issue. Taking the head off and then taking the piston out is your best bet. Might fluke it and just need one new piston. Quote Link to post Share on other sites
fiddlersport Posted November 26, 2014 Share Posted November 26, 2014 cylinder leak down test if you or your mate has one ? agree with Stu... head off and just pull the piston out, most likely if it is bad then it will fall apart in your hand when pulled out, happened to my mates ep Quote Link to post Share on other sites
