Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Galve and Duratec

Our ex 3.7 Roadster was Feb 2016 and definately had a galvanised chassis, so maybe this was spec'd to order.

Seems a backwards step to stop galvanising chassis. Lucky my 2014 4/4 has one .

+1

Ditto my 2014 4/4.

+2 I guess driven by cost & environmental issues.

Hello

Quid chassis plus 4 of 2017 and 2018?
Galvanized or painted?
Thx

Almost certainly electrophoretic treated. This was standard from early 2016.

A few galvanised chassis were around through 2016 at extra cost, and unlikely to be dealer specced. So a slim chance of a 2017 being galvanised customer order, but little chance if 2018.

So between a plus 4 duratec of 2013 2014 and a GDI of 2017 2018 which is the best choice? Because there is 2 interest cars to sale in Germany.

Is those 2 engines have the VVT system and the same engine blok?

Thx

Personally, I would choose the older of the two offers if everything else is right. I have forgotten exactly when the GDI arrived. If the older car has a Duratec with intake manifold injection, it is not a VVT. But that wouldn't stop me from buying it. The older engines are very common in the tuning scene. Not only with Morgan. Have a look at Montegue's threads to get an idea of what you can do with the older Duratec. There is an ECU update for the GDI engine, but that's it. You can't change much. Ok, not every driver wants to change much about the engine, but I believe that the old Duratec is a very reliable engine, apart from its tuning potential. It's not a drunkard either. If you read the posts here, it's no more thirsty than the GDI. And there are no problems with coked valves due to the intake manifold injection.

I am talking about a potential problem. So far there are no reports of GDI drivers here in the forum who have had this problem.

Yep, totally agree with Heinz. The indirect injection Duratec is the reliable one! All sorts of reasonably priced upgrades available too.

The racing world still use this option and lotus fit it in the 7's The direct injection Gdi squirts the fuel straight into the cylinder head whereas in the indirect injection the fuel is introduced into the inlet manifold which results in several advantages, probably too boring to go into fully here but simply the backs of the inlet and exhaust valves are constantly washed by the fuel/air mix which cools the valves and also washes the backs of them keeping them clean so this engine doesn't suffer from gummed up valves. I'm not sure but think that not all Gdi engines have VVT, perhaps just the later or Ltd. edition options fitted with the Mazda variant. but you will have to check that one out yourself!
The Gdi variant was developed for Ford America from the reliable and bombproof Duratec 2.0L and was fitted with a turbo charger, it quickly became known as the worst engine ford had ever made however in all fairness the non turbo version is better but! there are many cases of gummed up valves with as little as 3000 miles on the clock and its not a simple quick fix! and will become a regular expensive service issue. Many owners claim theirs is fine then they have a look and get a big shock.

Most of the crap causing this issue is from the Breather system and primarily from the crankcase breather which along with the rocker box breather is directed back into the inlet manifold where negative pressure helps to suck them back into the engine to be re-burnt helping to control emissions. directing the crankcase breather through a filtered oil catch system might help but it seems the jury is still out as the whether or not it still requires the negative pressure provided by the inlet manifold.. This would dictate whether or not you could then vent the crankcase to atmosphere after the filter or if the crankcase needs to have the aided vacuum, returned to the inlet manifold.
A vent to atmosphere might also cause an MOT issue so should be easily reversed back! New or low milage engines don't usually suffer with engine blow by and it seems that introducing a catch can system to the rocker box vent is probably a waste of time unless you are constantly working the engine hard such as in racing.
