Estafette Engine?

[r4 spain]

Good Morning all
Quick question. Is the 1108 engine from a Estafette exactly the same as the the renault 4 f6 engine.
And does anybody want my old engine. Needs collection from Hasting

Isn't the Estafette water pump on the other end of the head (different casting)?

Indeed water pump on other end but also a pulley on the crankshaft end, a different distribution chain cover, manifolds are different

Thanks. Would it be a big job to fit one into a renault 4?

Manifolds are different. But can a Renault 4 manifold be attached the Estafette head?
Im in the process of buying a refurbs Estafette engine. Getting abit worried now.
Waterpump shouldnt be to much of an issue. Is it a different waterpump as well?

Looking at the picture you see cross sections of the 688 engines.
Both engines left side is facing towards the front side of the car and thus the engines are reversed

Though in the base both engine are the same there are differences as early mentioned.

Waterpumps are different, the Estafette has a larger one which propelles the radiator fan, where the GTL/F6 have a electric operated radiator fan.
Distribution chan covers are different, manifolds are different, the engine block casting is different as @Andy McGhee wrote.
Estafette has pulley on crankshaft to drive the generator and waterpump so there's an oil seal in timing chain cover, GTL/F6 has pulley on the camshaft so an oil seal at camshaft end.
I would not use an Estafette 688 for my GTL/F6
The standard Estafette engine won't even fit.
