decepticonprime Posted May 24, 2013 Share Posted May 24, 2013 (edited) PROBLEM: My car smokes at HIGH RPM - white smoke cloud - oily smell and oil level drops. DOES NOT SMOKE at low rpm, normal drive or idling. If I press the accel hard let my foot off it smokes but if QUICKLY I press the accel again and let go - no smoke. INTERESTING FACT: The car SUDDENLY STOPPED smoking for a month on the current turbo. Just took the car out and going to work and boosted to see how bad the smoke is and no smoke! Kept it like that for a month and then it was time for servicing. I changed the engine oil, filter, petrol filter, gave the car a good wash and it started smoking again. TRIED: I changed 3 turbos thinking its the turbo seals and all of them smokes. Two of them I took from my mates and they didn't smoke in their car!TRIED: Adjusting the oil pressure but the risk of killing the turbo made me run it a bit rich again.CHECKED: Head gasket, piston rings, radiator, anti-freeze in oil and related matters - all ok. Engine compression test not done yet. NEW PCV on the way Car: Glanza V A/T with WEAK transmission soon to be replaced (today-tomorrow)Engine: Standard 4e-fte with mild steel mani, decat and 2.5" custom exhaustTurbo: Standard Ct9a with HKS actuatorOthers: HKS BOV (installed on top of cam, near timing belt cover, next to standard TMIC) and ebay oil catch can (going cusco soon) Can someone explain what is going on? I tried toyotagtturbo and no solution yet... this is killing me... Edited May 24, 2013 by decepticonprime Quote Link to post Share on other sites
funny onion Posted May 24, 2013 Share Posted May 24, 2013 Valve stem oil seals in the head? Quote Link to post Share on other sites
funny onion Posted May 24, 2013 Share Posted May 24, 2013 Could try the Pcv valve too. Just thoughts. Quote Link to post Share on other sites
decepticonprime Posted May 24, 2013 Author Share Posted May 24, 2013 (edited) If valve stem seals went shouldn't it be blueish smoke? But i'll open the head soon anyways. New PCV valve is on the way. Edited May 24, 2013 by decepticonprime Quote Link to post Share on other sites
TrisK Posted May 24, 2013 Share Posted May 24, 2013 If valve stem seals went shouldn't it be blueish smoke? But i'll open the head soon anyways. New PCV valve is on the way.You can test the pcv pretty easily Quote Link to post Share on other sites

New PCV valve is on the way.But you said it's using oil? Oil has to be going somewhere right? And unless there's a leak then it must be burning it. Blank the port on the inlet where the Pcv goes to and take it for a drive/rev it. The Pcv is supposed to close when driving/under boost. If its not closing properly it will chuck shit in the inlet.

Fozzie Posted May 24, 2013 Share Posted May 24, 2013 Couldn't be headgasket going could it? :/ Quote Link to post Share on other sites
decepticonprime Posted May 24, 2013 Author Share Posted May 24, 2013 Please bare with me.. i'm new to cars... learning from the internet. Ok will try the PCV test and the head's opened up will check the valve seals.My mechanic, my mates and myself are completely stumped as to why it stopped smoking for a month - any ideas as to why that happened?Opened the headgasket the first time I saw smoke. Turns out it was spanking new and no sign of damage... got the radiator serviced along with a system flush for good measure.Thanks for your input! Quote Link to post Share on other sites
funny onion Posted May 24, 2013 Share Posted May 24, 2013 Don't go pulling it apart just yet!My Pcv had an off moment one day in mc Donald's drive through the smoke coming out the back was insane. Best part was there was a trophy wife in a convertible merc with the top down and she was chewing on castrol for about ten minutes haha never did t before then never done it since.

StuDoc 72 Posted May 24, 2013 Share Posted May 24, 2013 When you did take the head off and found the gasket was spanking new? Im assuming you changed it again anyway? Since you removed the head you cannot reuse the gasket/headbolts. Quote Link to post Share on other sites

funny onion Posted May 24, 2013 Share Posted May 24, 2013 haha classic blanked mine off for good now and just left the pcv open to atmosphere.the only time it has smoked on the same scale since is when the pistons melted, and even then it was no where near as bad as you'd expect! haha Quote Link to post Share on other sites

Since you removed the head you cannot reuse the gasket/headbolts.When I first noticed it smoking, my thoughts were "headgasket" and thats when I opened it up a couple of months ago and yes, I replaced it.Well the head's open ... checking the valve stem seals today... regardless of the pcv condition, a new one is on the way... so lets see,,, Quote Link to post Share on other sites
decepticonprime Posted May 28, 2013 Author Share Posted May 28, 2013 In a recent development, my mechanic said that the oil pump is pumping out too much engine oil i.e the oil pressure is too high... ??? Quote Link to post Share on other sites
Addymk2 Posted May 28, 2013 Share Posted May 28, 2013 If its mega high it can force oil past the seals. Worth giving it a flush through with some of that engine scrubber next time you change the oil? Incase there's a lil block somewhere causing über pressure. Quote Link to post Share on other sites
5T4R7ET N/A Posted May 28, 2013 Share Posted May 28, 2013 Best bet is to replace PCV valve or take it out and put a pipe on vented to catch can. They can cause all sorts of problems. think the oil pressure problem will be related as faulty PCV valve will cause high pressure Quote Link to post Share on other sites

They can cause all sorts of problems. think the oil pressure problem will be related as faulty PCV valve will cause high pressure Some more details into how i'll be doing this? just yank out the PCV and route a pipe to the catch can with a breather? or I can stick a hose and breather right into the PCV? If its mega high it can force oil past the seals. Worth giving it a flush through with some of that engine scrubber next time you change the oil? Incase there's a lil block somewhere causing über pressure. Yep that is the plan... gonna do a complete flush with engine scrubber... Quote Link to post Share on other sites
5T4R7ET N/A Posted May 29, 2013 Share Posted May 29, 2013 ^^ you can just take the PCV valve out and put a pipe in there, make sure its a tight fit. (also make sure the PCV gromet is in good condition) attach the other end of the pipe to a catch can, that has two ports. the other port needs a breather on it. you will get oil condensation in winter in the catch can and occasional small amounts of oil if you drive hard for very long ( top speed run) Quote Link to post Share on other sites

IN OTHER NEWS... my mechanic said : "The piston rings need to be changed and there exists a gap between the pistons and the block"... I guess this was the reason for all the trouble?

1991 starlet owner Posted May 30, 2013 Share Posted May 30, 2013 Must admit mate the owner before me did this.. But I've just got a pipe (that's a good fit) going into a redbull can. Thought about getting a proper catch can but haven't as of yet.Tom. Quote Link to post Share on other sites
