2.1td exclusive auto. No drive

Post by citroenxm » Sun Apr 07, 2019 10:46 am

OK. I've started working on a 2.1td auto. 265k but with no forward drive. The box has been fairly well looked after.. Well to get to 265k it has to of been.. And the car has some sentimental attachment for the owner.. After owning it for some time.

Anyway. I sourced a replacement box.. But after reading mtxm and deans blogs on valve blocks etc it was worth removing the block for investigation..

I managed this today.. And took the plates off the sides to see what the block valves were like..

Firstly the valve lock had the vac/pressure pipe on it. It's connected to the td inlet where the boost pressure guage goes on S1 cars

You can see the pipe at the bottom. They are push fits.

All looks pretty clean in there..

And there for us is the bad news.. The plate sprung off.. With zero crap in there and no signs of Any dirt. All valves were free and more so for the milage no play between valves and bores.. So sadly not a sticky valve issue.

So.. I now assume its box out now then..

Look all clean to me...

And upper set of valves. I assume the one with the spring off should NOT able to come out. It wouldn't anyway..

My valve block issue was not obviously apparent when I removed the valves Paul, although normal service was restored after refitting, so you might just be lucky! Failing that I would be pulling the governor next. With regards, Matthew T.

Well to be honest mathew.. The car is at such stage that one exhaust manifold to pipe bolt to do.. Bottom hose at back lower of engine.. And regulator and flow divider returns are all that need removing to get the whole lot out...

Well I opted to take the whole lot out. Which turned out to be a damm good idea. As the steering rack boots were shot as also were the pas ram bush's. So I found a decent rack and swapped that over. While the lot was out we fitted a new cam belt and water pump.. And also there was play in the half shaft bearing.. All far easyer to do while it was out.

Its back in now and drive shafts and exhaust bolted up.. Rear water hoses connected up.. Lhm tank on.. So progress is comming along.

I'm gonna retain the auto box external rad cooler. I think even though it takes up a bit more space behind the rads it's worth the extra cooling assistance..

Should not be too long now and we shall find out if she goes forward again. The box happens to have fluid in it however a fluid drain and swap is on the cards. No doubt all the oil is in the dump now so a good idea to do it..
