The detail and photos on this thread
are fantastic better than any book
out there.

Thanks neil

Yes, very impressive, might even overhaul mine one day

[slowcoach]

Yep, mind boggling. Love all the photos, nice to see all the magic goings on inside

Have you thought about putting it on a rolling road after completion Paul? Will be interesting to see the figures/results after a complete rebuild and how that might change over time.

No not really, sounds expensive.
After reliability not power, went DJ just so I can tow without crawling up hills ( and because bits became available) . I don't need to tow but thinking of a boat or small c***van in future.

thanks for the comments, it's not over until the fat lady starts knitting again

No worries Paul although you might be pleasantly surprised mate - chap local to me was going to charge £90 but that was for a full set up with tuning etc. Just thought would be interesting to see what the bhp/rpm figures were with your new engine.

Tis looking good though mate

Seems a shame to rip this out as it's going so well and only been in 5 months...
It will be my spare assuming the engine works ok

Will the exhaust fit straight onto the 2.1?

[itchyfeet]

yep, it's the same engine case, the only difference is the crank, cam, pistons, dizzy and oil cooler.
of course a DJ is injection but it will run in a 2e3 carb as the DG does.

One of the best build threads for a long time, nearly as detailed as the build itself, I've been keeping an eye out for updates for a few days now.
Are you fitting a remote oil cooler or fitting the standard one?

standard oil cooler, it was already there on my DG to help with low oil pressure

Hello,

A small patch of blue sunshine on your horizon..

[quote="itchyfeet"]Oh well, if you never made a mistake you probably never made anything.



When I was doing beetle engines in the 70's and 80's we used to come across this regularly,..

especially from a certain VW machining company in South London..

Frankly it never caused a problem...

If you are going to use oversize guides, it is best to ream the receiving holes to just under..

Then, belt and braces, you use bearing locking compound before straight away driving in the guide either in the press, or with an air hammer..

Onward and upward..

Cordialement,

[itchyfeet]

Thanks John
Are you saying you would fit this?
I drilled a hole to relieve the crack.
What concerns me is a crack in an Aircooled here would not leak coolant, so may not be an issue.

cheers
Paul

Excellent story line here.

Question Itchy - now you have a DJ engine, will that mean your LPG will need setting up again, or should it not matter?
I'm thinking different compression values and volumes etc...

I have closed loop with a lambda sensor so the system will automatically compensate I think it's always trying to keep the mix stoich, my air fuel guage tells me its pretty good at it.

What I need to get around to is a throttle position sensor to help rapid acceleration, its a bit slow to respond because it just uses the lambda sensor at the moment, so foot hard down it's lean for a second while the system reponds.

My guess is open loop needs readjusting but I may be wrong.

good question smiffo
