Re: early to late engine swap

Hi-I'm not an expert but I can tell you a little from my own recent experience. My 85 DG blew up (valve embedded in piston etc.) It turned out to be an OLD DG with the main differences being: Crank bearings are not the same: OLD engine:bearings different size and integral thrust flanges-NEW engine: ...

Re: rocker assembly

not sure if this helps but 4 things come to mind from my w/c dg : assuming that you know these are the right rods and rocker sets: are rods centred in the tappets, they slip off centre easily? adjustable end of rockers go to valve stems not rods rocker shaft mounting brackets should be fitted with t...

Bench test of water jacket seals

I have spent the last 2 months rebuilding my DG. It is now nearly ready to go in. Every time I think of the design of the waterseals I am scared of failure, although I have never had one go on me and i know there are many who stand by it. However, the idea of putting it back in and finding that my w...

Re: cylinder liners base and top seals-sealant or not?

cheers for that, seems like such a vulnerable design when you look it, feels as if it need something to "fill the gaps". anyway, both heads back on today and we shall see soon how it goes-thanks for your help again

cylinder liners base and top seals-sealant or not?

Any views please on the use of any sealant mastic in addition to the new rubber rings and well cleaned and flatted mating surfaces? I can see haynes/bentley don't suggest it but I wondered if regular rebuilders used something to "help" a potentially fragile design and if so- what?. Have lo...

DG oil pump gears and other questions re DG/2.1 options

just noticed that each of the oil pump gears have a dot stamped on two of their teeth. In rebuilding is it necessary to align these dots please? Is it true that a DG/DF case can accommodate a 2.1 crank with minor modifications and, if so, are there suitable liners and heads that fit to the Dg/DF cas...

Re: valve guide replacement 1.9 wbx

Cheers for that, have acquired two spare heads in far better nick than existing so have done a straight replacement with those (valve guide wear low and faces etc in good nick) but may well get them leak tested as suggested. Thanks for the help
