Rossco1991 Posted October 4, 2014 Share Posted October 4, 2014 Hi guys, bought a glanza few weeks ago it was cheap cuz the rings had gone and was low on compression, I have stripped if and fitted new oem 74mm rings put it all back together wither new head gasket and bottom end bearings. Just gone to fire it up and it wouldn't start so I put the compression tester on it again and it's only reading 50 psi on all cylinders, I checked the bores where not scores and honed them to break the glaze, can anyone think what eles it may be? Thanks Quote Link to post Share on other sites

Rossco1991 Posted October 5, 2014 Author Share Posted October 5, 2014 Well I chucked some oil down the bored and tryed it again and and compression went up to 75psi I hav re checked the timing and all the marks line up? Quote Link to post Share on other sites
rwdrev Posted October 5, 2014 Share Posted October 5, 2014 have you double checked that you have the head timed correctly? 2 dots to 1 dot? not 1 dot to 1 dot. have a quick search and make sure the cams are lined up correctly. also, when removing cams did you put the service bolt in?

Sudden Posted October 5, 2014 Share Posted October 5, 2014 Is the cylinder bore of the engine stock? Oem 74.m rings in a bored block might cause this Quote Link to post Share on other sites
Rossco1991 Posted October 5, 2014 Author Share Posted October 5, 2014 Yes the two dots line up wiv the single one on the back of the cam gears, and no I didn't know about a service bolt? Where does this service bolt go and what does it do? Quote Link to post Share on other sites
