"Dropped valve" broken disco 200tdi in a 110

[Landy'd Gentry]

Driving my son home from school tuesday evening, my 110 wasdown on power and horrible knocking noise from engine bay.

The very nice recovery chap, diagnosed the problem with a "dropped valve".

Took the rocker cover off today, and low and beholed a pushrod was broken, thus not operating one of the valves.

the engine is a 200tdi transplanted from a disco.

Do I replace the broken pushrod and hope for the best, or any advice would be gratefully recieved.

Before spending loads of time and money pulling anything apart or expecting the worst

I would replace the push rod as it’s the cheep option.

Turn it over by hand before starting just to make sure, if it stops you have a bigger problem.

I had a timing belt go while ticking over and bent four push rods.. no damage to valves or piston’s

I was lucky and as far as I know the engine is still going strong.

You may well be lucky also.

Got to wonder what broke the push rod though.

Any idea?

Just turned the engine over by hand, and it appears the other valves are operating as per normal.

So not too sure, but going to do some more investigation.

Remove the other pushrods & roll on a flat surface so the rocker cup end overhangs, you'll soon see if any are bent,

are all the rocker arms striaght ? if not replace any suspect ones,

maybe that one pushrod wasn't seated in the cam follower correctly or the follower/slider/roller is fualty.
