Thank you for a very detailed reply.

I ordered a couple of manuals that I was able to lay my hands on: TP30871/1 and TP31003/1, couldn't justify the higher price for the reconditioning one. Sent a couple of emails to OTP (Original Technical Publications) about missing B230 engine manuals from a supposedly complete 900-series collection, but got no reply.

My experience with accuracy of dates in Volvo green books has been variable: I have a suspension manual that says in the front pages it's current to some year like 1991, though it has sections about 1996- 960/S/V90 series cars. Can't say if anything like that would apply to the B230 manuals.

Volvo lists (at www.volvotechinfo.com) TP30871/1 TP31003/1 TP30927/1 and TP31083/1 as their Section 2 (Engine) manuals, the rest of the Section is about 4-valve engines, EGR, LH2.4, Regina, Cruise etc. There's also a 2-page supplement in Section 2, Group 21, TP31311/1S "Crank Shaft Journal Specification Revision" which may be interesting to check out, but I haven't seen that one around.

Asked for the same on the turbobricks.com as well.

And yes, the car is a 1992 740 turbo; the engine block is now off the car, there's been some surface rust that led to things seizing in the car, but things got free (mostly) after applying copious amounts of PB blaster. Can't get myself to junk the block, and haven't found a better one at local scrap yards yet. Have lots of other parts for this car, and it's a very slow going project.

Thanks!
