Sefton-EP91 Posted March 16, 2014 Share Posted March 16, 2014 Just before I start... The car is a 1998 glanza v 4efte. The turbo is a ct9 custom hybrid built by Liam d at midland turbos and has done literally 20miles yes 20 miles so the turbo is for now out the equation hence why I put it under engine related. Since fitting my WEPR power up kit yesterday I have now been experiencing white smoke on idle and itermittently blue smoke when driving, I checked the coolant overflow tank and I also have noticed and considerate amount of carbon deposits in there. Back to the smoke, when I start the car from cold in the morning the WHITE smoke is stupid amount literally clouds of it. One slight blip of the throttle and it turns to blue. When the car is at optimum temp the white smoke start to settle but is still there. Whilst driving the smoke is blue but most of the time unnoticeable. My thoughts are that the head gasket has gone hence the carbon in overflow tank but this does not explain the blue smoke. My first thoughts were PCV Valve intermittently stuck open or closed but this is a guess! Thanks in advance for any feedback, it is much appreciated! Quote Link to post Share on other sites
Mikeyallgood85 Posted March 16, 2014 Share Posted March 16, 2014 What's the mileage? Sounds exactly the same problem as I'm having! I've been thinking it's the valve seals! Quote Link to post Share on other sites
richardc9052 Posted March 16, 2014 Share Posted March 16, 2014 get a compression test done Quote Link to post Share on other sites
Sefton-EP91 Posted March 17, 2014 Author Share Posted March 17, 2014 A compression test was defo going to be next course of action. I will feed back with my results. The mileage is 152k km 20.000 of thise are miles.. Quote Link to post Share on other sites
Sefton-EP91 Posted March 17, 2014 Author Share Posted March 17, 2014 (edited) Right tonight I have carried out a compression test my results were, with WOT and engine warm.Dry test: Wet test:Cylinder 1: 170 Cylinder 1: 220Cylinder 2: 172 Cylinder 2: 220Cylinder 3: 170 Cylinder 3: 220Cylinder 4: 170 Cylinder 4: 220Could people please give me there opinions on these results. In my eyes they are bang on but would just like clarification on that.On removal of cylinder 2 spark plug before the wet test, the plug was very wet which would indicate coolant in the cylinder and would also explain why the result was ever so slightly higher on that cylinder. Correct me if I'm wrong..? I'm very certain that my issue is the head gasket at this stage. Thanks. Edited March 17, 2014 by Sefton-EP91 Quote Link to post Share on other sites
Mikeyallgood85 Posted March 17, 2014 Share Posted March 17, 2014 They are good results bud nothing wrong with the engine! ;-) Quote Link to post Share on other sites
Sefton-EP91 Posted March 17, 2014 Author Share Posted March 17, 2014 But spark plug number two was wet mate. So could it still be the head gasket even though my results were bang on? Thanks Quote Link to post Share on other sites
richardc9052 Posted March 17, 2014 Share Posted March 17, 2014 Does your coolant level drop much? Quote Link to post Share on other sites
daniel_g Posted March 17, 2014 Share Posted March 17, 2014 Sniff test for HG failure. Could be piston rings worn, would explain the rise in comp and the blue smoke. Was the wet plug defo coolant, not fuel ? Quote Link to post Share on other sites
Sefton-EP91 Posted March 17, 2014 Author Share Posted March 17, 2014 (edited) I will have to whip the plug out again and have a good sniff to make sure it wasnt fuel, I did have little sniff and im pretty sure it wasnt fuel. Tbh I havent really noticed a drop in coolant level but this could just be were I havent driven it. It's doesn't make sense because there is quite a bit of carbon build up in the overflow tank. Also when I take the rad cap off the coolant level rises and bubbles over when the accelerator is pressed. Which would indicate to me that there is something pressurising it? When I do a sniff test should I do it over the radiator or over the over flow tank. I suppose either will do..? Edited March 17, 2014 by Sefton-EP91 Quote Link to post Share on other sites
daniel_g Posted March 17, 2014 Share Posted March 17, 2014 Either will do, i always do it from the rad just incase theres an air lock in the system and it doesn't circulate properly. Quote Link to post Share on other sites
Sefton-EP91 Posted March 17, 2014 Author Share Posted March 17, 2014 Ok thanks mate ill give that a try and feedback with my results Quote Link to post Share on other sites
richardc9052 Posted March 17, 2014 Share Posted March 17, 2014 If there's pressure in the coolant with the cap off the head gasket is gone. Quote Link to post Share on other sites
Sefton-EP91 Posted March 18, 2014 Author Share Posted March 18, 2014 It Bubbles over when Cap is off and accelerator is pressed. So I would say hg has gone. I'm going to do a sniff test tonight. I will feedback with my results. Quote Link to post Share on other sites
H_D Posted March 18, 2014 Share Posted March 18, 2014 I think its the valve stem seals - compression results look good. Quote Link to post Share on other sites
Sefton-EP91 Posted March 18, 2014 Author Share Posted March 18, 2014 I was also thinking the results were good. I would have thought that putting oil down the bores would fill the ring gaps hence the difference in compression. Rather than the rings being worn. I'm going to do a hg sniff test tonight after work and I will feedback with my results. If it is the hg I will be replacing valve seals at the same time. Quote Link to post Share on other sites
