Off topic (I've a separate thread asking this question) - I can see there is a hole drilled below the TPS, does it go all the way through? (and is it purposeful?). I'm trying to figure out if its supposed to be a leak, or not!
Looks to be on the atmosphere side to me - so not a leak.Thanks for your replies - Yes this is where I am confused, the TPS needs a gasket, but there is a gaping hole drilled below it anyway. The smoke tester had a column of smoke pouring out of it, which I assume will turn into unmetered air when under vacuum. I have a tester with pressure leak guage, and between the 3 leaks it was not really able to build enough pressure to give an understandable reading.

probably should continue this on your other thread:https://www.pistonheads.com/gassing/topic.asp?h=0&...
as mentioned on that thread, i dont expect the shaft to be airtight, assuming the shaft itself isn't worn. I tended to put a blob of very thick grease on the shaft when reassembling to help sealing a little.

have they put a sleeve over the wafer thin remains of the original inlet sleeve? (therefore not 72mm - as 72mm requires full removal of it)
No they'd bored it broke through the lower (the area you want welded up) then put a thin sleeve into the remains and bored that (wafer thin) IIRC that port/passage in shot hides the slight mismatch/overlap in that shot Gassing Station | Griffith | Top of Page | What's New | My Stuff
