hi, the turbo has been rebuilt, so i gave the engine a comp test : a dry test gave a reading ,varying by about 5 psi at 125 psi. each cyl. a wet comp test gave a reading of about 175 psi in each cyl .varying by about 5-10 psi.
so looks liike the rings are stuffed. ii dont know why, the rings and pistons are brand new, having done about 50 km before it started to blow smoke. the injectors , the guy said when i got it tuned, are running at about 90% duty cycle.maybe when i hit boost, its starting to lean out a BIT and is causing the rings to stuff up.? i know that once when i hit boost for a bit, it said "max duty" on the digi one display....maybe not supplying quiet enough petrol at max boost? does any body know of any top quality rings i can get for it? pistons i am using is z20 pistons. hope fully the pistons are okay, there is no sign at all of breather smoke out the rocker cover ..... last time the piston (s) went (due to incorrect fuel settings?) it blew a heap of breather smoke.......so ...................i hope i dont have o buy another set. mark k --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ ---------------------------------------------------------------------
