20brad20 Posted June 1, 2011 Share Posted June 1, 2011 Hi everyone im a newbie to uk starlet club and to starlet gt turbo engines. I recently purchased a ep82 that had been tinkered with a little. It has a twin breather cam cover front mount intercooler hks actuator etc. I turned up the boost to about 0.9 bar on purchasing it after a few weeks i gained a slight smoke of throttle and on idle after 4-5 mins of running. I bought a recon ct9 turbo and compression tested the pistons and all seems to be fine but still smoking. To cut to the chase could anyone help with what it could be.....Valve stem seals, scrapper rings, bad oil etc????Any help Thanks!!!! Quote Link to post Share on other sites
GT Phayer Posted June 1, 2011 Share Posted June 1, 2011 blue smoke is oil so will proberly be stem seals as if a ring was damaged the compression would be down if im right ? Quote Link to post Share on other sites
greasemonkeyspb Posted June 1, 2011 Share Posted June 1, 2011 possible valve stem seals mate have you tried compression testing with a spoonful of oil down the bore??? gives a slightly different reading if piston rings are slightly worn mate or if valve stem seals are slightly worn mate just something to try? did other turbo go then?? as might be bit of oil left in exhaust if it did??just few things to try??ste Quote Link to post Share on other sites
20brad20 Posted June 1, 2011 Author Share Posted June 1, 2011 Yer turbo has gone on and i have done about 50-60 miles after putting it on! didnt look like there was any deposits left just burning it badly i think! Would it not smoke all the time on valve stem seals? thanks for the fast resonse guys! ;) Quote Link to post Share on other sites
greasemonkeyspb Posted June 1, 2011 Share Posted June 1, 2011 slight on tickover mate then bit more under accelleration mate and if bad enough when you let off are you sure about that turbo?? may be seal leaking internally??ste Quote Link to post Share on other sites
