Rossco1991 Posted October 4, 2014 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
Rossco1991 Posted October 4, 2014 Author Posted October 4, 2014 I cleaned all the pistons and checked them all they looked fine all the ring grooves where fine to! Quote
mikey4410 Posted October 4, 2014 Posted October 4, 2014 How many miles has the car done before you did the test ?? Quote
Rossco1991 Posted October 4, 2014 Author Posted October 4, 2014 128km, I think it's the bores hav worn! I hav cut my losses and started taking the motor out! Quote
5e colin Posted October 4, 2014 Posted October 4, 2014 sounds like timing 180/or 90 degree out its deffo in the head mate !!!! OR gasket ??????? Quote
5e colin Posted October 4, 2014 Posted October 4, 2014 How many miles has the car done before you did the test ?? makes no difernce how many mile he done . new rings in the bore spikes up compression bedded in or not mike Quote
Rossco1991 Posted October 5, 2014 Author 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
rwdrev Posted October 5, 2014 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? Quote
Sudden Posted October 5, 2014 Posted October 5, 2014 Is the cylinder bore of the engine stock? Oem 74.m rings in a bored block might cause this Quote
Rossco1991 Posted October 5, 2014 Author 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
