1). I have an Australian 1989 Waterboxer Transporter. My previous VW was a 1970 type 2, purchased by my father in 1970. I rebuilt the type 2 myself using the idiots guide (primarily), a gregory's manual and advice from two reputable Australian rebuilders (when my information conflicted). The only things that I re-used  internally were a linished camshaft and the conrods (after I balanced them). My waterboxer has done 130,000km's and I although it is still running well, I am considering my next rebuild now. Has anyone done this themself and would you recommend it to someone like me who has the tools and knowhow for a 1600 aircooled rebuild. I have a bentley manual and from reading the archives will be purchasing the haynes.

2). A more pressing problem is my five speed transmission jumping out of second. I am about to have it rebuilt for a rough (wait and see) quote of $2000 - $2500. (this job is beyond my tooling and knowhow). My gearbox is whining, although not too loudly, and the whine starts low and rises in pitch with each gear change. I am hoping therefore that it is not a crown and pinion problem as shouldn't this be a constant whine governed by the roadspeed? Can anyone suggest the cause of this noise.? 

3). Can anyone suggest how to determine if I have a "coolant into cylinder" leak. I would love to test for this.

Dominic

P.S. My friend who bought my type2 reports that it is still running well after 40,000 miles. Thankyou idiots guide, Stan Pobjoy in Sydney and Mick Motors in Brisbane.
