I have a 1.7 8v 33 engine that had injection and a dizzy fitted, it is a hydraulic tappet engine.

two of the inlet valves are bent on one bank, if I don't manage to locate replacement valves would I be able to use different heads on the engine?

my choices are:-

hydraulic tappet heads from a 1.6 boxer from a '95 145

hydraulic tappet head from a 1.3 carby 33

mechanical tappet head from a 1.3 carby

I measured the valve diameter from the 1.3 that's in bits to compare with the 1.7 and as expected they are smaller, but not by much. Would this choke a 1.7?
I cant measure the 1.6 as its not in bits and I kind of want to keep it like that as its a good engine, just not set up for carbs yet.

Any help on this one would be great Gents!

Hi,

The 8V hydraulic tappet heads are the same on the boxer engines
(including the 145/146 8V models).
The valve head diameters are 39.7 - 39.9 mm for the intake and
33.0 - 33.2 mm for the exhaust valves.

The mech lifter heads are equipped with different cam pulley and camshaft.

Maybe worth a try to call the sales helpdesk number at the following site: http://www.enginepartsuk.net/osvat

Ok, thanks for the reply, that kind of answers my question. Once the valves are the same diameter I should be ok, cam profile differences aside that is.

Thanks lone wolf!
