Dnk Posted September 27, 2012 Share Posted September 27, 2012 (edited) Looks like condensation to me, the hesitation on number 1 tubby could be a split vac hose, sticky waste gate, faulty boost controller if you have one? Many things to check before looking at turbo failure... Once any condensation is burnt off it shouldn't re appear while driving, as i showed in my photos its not cold enough yet to be suffering this. I'd be inclined to get a sniff test done on the coolant seeing as that's cheap and very easy to do Edited September 27, 2012 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
listy Posted September 27, 2012 Author Share Posted September 27, 2012 A sniff test is for emissions yes? Sensor goes in exhaust? That's what the reme mech in the workshop said anyway. Quote Link to comment Share on other sites More sharing options...
listy Posted September 27, 2012 Author Share Posted September 27, 2012 Smoke test came through 1.11 with mean value 1.11 Came out with a pass Providing that is a sniff test At least I won't have to pay extra to pass emissions on the next Mot - - - Updated - - - Can't find any split hoses either.

Tyson Posted September 27, 2012 Share Posted September 27, 2012 Half way through doing a full service now, and the oil was changed when i did the oil pump a few months ago. Brake and power steering being done hopefully this weekend. O2 sensor not sure about, might just replace it anyway. Fuel pump and filter being replaced soon too. Dont have an AFR guage. How else can I tell if its rich or not? Saying that, a little rich is better than a little lean You changed the oil pump, why ? If it was failing then maybe it blew one of the turbo seals due to oil starvation ? Just a thought. Quote Link to comment Share on other sites More sharing options...
listy Posted September 27, 2012 Author Share Posted September 27, 2012 Oil pump was changed when the fms went. There is no oil coming through the exhaust which is a good sign, or forward to the air filter. I'm thinking it may be the fuel filter clogging up as it seems to happen most when the fuel is below 1/4 tank. So am going to order new pump and filter tomorrow.

Dnk Posted September 27, 2012 Share Posted September 27, 2012 A sniff test tests the coolant for exhaust gases, you fit a bottle where the rad cap is with a colored fluid in it then run the engine, if there are exhaust gases in the coolant then the fluid changes colour Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted September 27, 2012 Share Posted September 27, 2012 Looks like condensation mixed with normal exhaust soot. I wouldnt worry. Mine is similar to that and i have a fresh engine rebuild ect. Mine goes after a good blast Quote Link to comment Share on other sites More sharing options...
listy Posted September 27, 2012 Author Share Posted September 27, 2012 Right I'm no longer worrying about the white smoke, as I've checked all I can check and all seems fine. However, I have noticed fresh oil seeping from the sump! The reme vm said the vm who helped me with the oil pump used the wrong sealant on the sump which has started to break down. He reckons this could cause a drop in oil pressure, leading to the hesitation. So next week, the sub frame is getting dropped again, sumps off, reseal, back on. Also, going to order a new fuel pump and filter and fit those. Going to see if I can get hold of a fcd / bcc and fit that too for full bpu Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted September 27, 2012 Share Posted September 27, 2012 I would have thought it would be peeing out if it caused a loss in oil pressure, wouldnt have thought a little weep would cause any worries. Quote Link to comment Share on other sites More sharing options...
listy Posted September 27, 2012 Author Share Posted September 27, 2012 I dont know to be honest. All I know is that it was hesitating before the oil pump was changed, then it stopped for a couple of months. Now its doing it again, and there is oil seeping from the sump. I'm just putting two and two together here. I may make 4, I may make 5. Will just have to wait and see I suppose. Quote Link to comment Share on other sites More sharing options...
listy Posted September 28, 2012 Author Share Posted September 28, 2012 Lower oil pan is off, and my god! All the sealent is sitting in the bottom of it! I'll upload pics when I get home later. Still a while to go in the workshop yet. It's hard work with only one pair of hands! Quote Link to comment Share on other sites More sharing options...
listy Posted September 28, 2012 Author Share Posted September 28, 2012 A few pics of todays work. On the ramp. Sealant debris in the lower oil pan. Quote Link to comment Share on other sites More sharing options...
Ian C Posted September 29, 2012 Share Posted September 29, 2012 Also, your HKS mushroom filter won't be helping, they are notorious for letting through rocks and gravel into your engine Quote Link to comment Share on other sites More sharing options...
mellonman Posted September 29, 2012 Share Posted September 29, 2012 mine was abit like tha even the stock turbo returns where abit gummed up Quote Link to comment Share on other sites More sharing options...
listy Posted September 29, 2012 Author Share Posted September 29, 2012 Right then. The smoke issue seems to have gone after the car has been in the workshop a couple of days with the exhaust off. Think because of the rain water was just sat in the exhaust. Resealing the sumps all went well also. Even though I did have a MASSIVE mong moment, after I had the subframe etc back on, started the car, and oil started gushing out everywhere. A scream of dismay ensued, and I quickly turned the car off. After having a look, I realised I hadnt put the two nuts from the oil return pipe? back on, so naturally oil made a quick exit from there! Put that back on, topped up the oil again, and all is good. NO MORE LEAKS The hesitation issue I think I have solved also. I'm pretty sure its gunk clogging the fuel filter/pump. The car was very low on petrol when I finished, and on the way to the garage to fill it up, it was doing the same thing all the way. (I think it was because the tank was nigh on empty though, filled up with 68 litres!) It also occured to me it only seems to happen when I drop below 1/4 of a tank, so I think with little fuel in, the gunk just gets sucked up, limiting the fuel getting through the system. Once it was full, it didnt hesitate once. So, possibly new fuel filter at some point, and a clean out of the fuel tank is in order. Not sure how to do this though, as with a blended in Trial rear, I cant get at it from the bottom, so unsure if I can get in deep enough from the fuel pump access? I'll have to do some research. Anywho, smoke issue dismissed Sumps sorted Hesitation figured out All in all, a good couple of days work. I'm going to hate it when the battalion get back from Kenya in 4 weeks, as I wont have unlimited access to the workshop like I do right now But hey, I'll find a way Quote Link to comment Share on other sites More sharing options...
