Hi All,
This is a turbo first off. So I'm willing to accept that I failed at front seals and redo them again but first wanted to get a reality check. So the tale is that about a month ago I noticed oil seeping from timing belt cover so I went and replaced timing belt and seals. I didn't have special tools just cleaned carefully and tapped them in "flush" with pvc pipe sections of approximately the same diameter. Then after giving it time for excess oil to clear out (belly pan removed for better observation) I determined seals were still leaking so after some reading here I disassembled it and tapped them about 2 mm in hopes of finding fresh surface. No luck, week later still seeping. Next I went about making sure it was not caused by crankcase pressure - the "non-flame trap" and all piping and oil separator are 100% and I even drilled out the brass nipple at the intake a little to try to boost the vacuum at the Y fitting. So I now measue 17 PSI of vacuum at the intake and about 2 or 3 PSI at either end of the Y fitting. For the actual crankcase pressure I had to switch to a homemade manometer which shows about 1 inch of water vacuum at the dipstick tube and since I read several posts saying you should have about 2 inches I will put that reading with the margin of error of my crude meter. Also if you hold the unthreaded oil filler cap just right you can feel the slight suck down that wins over the dance with just a slight hand pressure. So now the question - just go ahead and redo the seals? Does the tapping technique increase the chance for leaks like I have? Thanks,
