Thread: TD5 Low Power

Hi All,
Let the games begin! A little history.
I bought a D2 TD5 about 2yrs ago as a donor, but I found it was in much better condition mechanically than my play car, so I started to fix it up ready for RWC.
In another thread I mentioned a botched exhaust stud repair so I needed to swap heads. I had one skimmed and it sat in my shed for 18mths as I work away.
Due to the virus, I was able to work from home so had time to finish this project!

Cleaned up the block, assembled the head and plonked it on. After a bleed she fired up and ran pretty sweet I thought.
So just before I booked it for RWC, I took it for a short drive up my street - she wouldn't pull the skin off a custard!
A stall test had the revs max out at 1950. This is consistent with the max revs on the road test.
So it's fault finding time!

A couple of fuel mistakes I prob need to address as well.
I didn't drain the tank and replace the old diesal. I just topped up with fresh so I will be doing that and replacing the filter, as it could be starvation. I could also swap the pump from my donor, but I'd like to check it first.
One time only I noticed a heavy diesal leak from the rear of the engine, so I suspect fuel regulator. I haven't been able to get it to happen again but I'll swap that as well. (It's a disco, I will swear doing that!)
I have noticed that there is a slight miss every so often at idle so I need to sort that but, if it's a blocked injector how do I test that?

MAP and MAF will be swapped out coz I've spares (unknown condition but worked when I last used them).

I'll then look at the boost. I have a nanocom so I have mapped the injectors and there are no fault codes.
I swapped over all my silicon intercooler hoses and fitted a D2a intercooler.
I've swapped the modulator but will bypass and then check the actuator as they're easy to eliminate.

Could be a frustrating few days!
Any tips?

Cheers
Ralph

Well, hopefully it's sorted. I methodically checked all the turbo and intercooler pipes and hoses and low and behold, I'd left a hose clamp loose on the turbo side! Easy fix for the win!
