T25 1.6D easy to stall, no low rpm torque

Postby Paul773car » 28 Oct 2019, 14:03

Hi all, i have a 1.6d non turbo t25. I’ve only had it a couple of months now and I’m working my way through all the problems one by one.

Year of manufacture 1984
Engine size 1.6D
Engine code if applicable CS
left or right hand drive Right
transmission type: auto/manual Manual 4 speed
Fuel type: lpg/diesel/petrol Diesel


The issue I’m trying to solve now relates to really poor low down torque. On any sort of hill i really struggle to get the van moving and it often stalls on any inclined hillstart. It revs fine but just doesnt seem to have enough power to move the van. If i ride the clutch a bit it will eventually move but that obviously not the right thing to do. Once moving its fine. It will do 60-65 quite happily in top and although it slows a bit for hills it has enough power when moving. Any ideas as to why? I’m thinking maybe, timing out a tooth? Injection timing way off? I was also thinking maybe clutch related but the fact it stalls rather than slips has me stumped

Thanks for any suggestions

No one?

Are they all like that then and I'm missing something?

I haven't owned a diesel before but I always thought diesels had more low down torque than petrols?

Thanks

It's not that us diesel owners are ignoring you. I've certainly never had that sort of problem so can't really help I'm afraid. Yes they do normally have more torque for pulling away.

I had similar with mine some time ago (though mine is a 1.9 1Y engine) where it would struggle with hills but ran fine otherwise, turned out to be a restriction on the air intake side. Have you checked the air filter isn't clogged? Also check for any other restrictions/collapsed air hoses.
