OK so recently the 147 JTD Ti has not been happy, not happy at all – this has made me not very happy, not very happy at all
Symptoms have included partial loss of power, occasional smoke smoke a WW2 destroyer would be proud of, a big dip in MPG and then a sudden and total loss of power
No matter which gear or how much I pressed the loud pedal, sod all happened. Symptoms before that had been a distinct hesitancy and the occasional ‘flutter’. Previously I have stripped off the EGR (as per the excellent guide on the forum) and cleaned it up although it wasn’t too heavily sooted up and worked well.
No error messages, the intercooler pipes are fine, the intercooler is fine. Actuating arm on turbo is fine.... but I will be replacing the vacuum hosing because I have the pipework already.
Can you tell what it is yet? That’s right…… it’s the damn inlet manifold
I had a quick look at it the other day and it was black with crap. A quick nudge around in the crap revealed the connecting arm for the swirl flaps wasn’t actually connected to anything at all – probably not been connected for some time either
I was immediately vexed. I cleaned the EGR again for the hell of it (pretty much clean to be honest and working fine).
My mood didn’t improve when it became clear that the flaps on 1, 2 and 4 were all ‘lying’ at different angles as the pins that should go into the connecting rod were all to foghorn leghorn.
Also they seemed a smidgen stiff in place… almost as if they were somehow seized. Much cleaning later the heads, and hopefully the flaps, now move more easily (aren’t seized) but it’s clear all is not well with the swirl flaps. The linkage/connecting arm is also well and truly knackered. At least the control flap on cylinder 3 seems to activate OK.
So other than getting shot of the car PDQ my only option is to take off the manifold and either buy a brand new one and make it all good as standard or find a second hand manifold, remove the swirl flaps, blank off the gaps and bolt it all back together again but this time fit EGR ‘restriction’ gaskets when bolting the EGR back on. The second option has some appeal and to honest I think it makes the most sense. Yes, I will remember to leave the arm actuator/sensor stuff all connected as I know I’ll get a multitude of error messages without it.
So a word of warning folks – check those flaps!
Any hints and suggestions on part sourcing? I’m thinking there’ll be a Vauxhall part that will be a bit cheaper if I buy new
I'm not adverse to second-hand bits!
