EGR removal on a Td5 ? - Done it !!!!!

<< < (5/5)

Range Rover Blues:
I can easily understand the higher emisions without EGR but as all it does is reburn unused fuel it's more of a PITA than owt else.  It can help stabilise combustion chamber temp a little but mainly over time it allows the inside of your inlet to get full of soot, that's where the penalty comes.  Bin EGR and bin the oil vapour connection and keep the inlet clean.

Just ordered the D44 removal pipe from Devon - even at this time of the day (16:05), they'll despatch and it will be delivered tomorrow !!!!

Thanks Tim  :wink:  :wink:

Fitted the 'EGR removal pipe' kit from D44 this afternoon - fairly straightforward, although I had to phone Devon to find out how to bypass the cooling system on the EGR pipe (its seems the later Td5 EGR systems have an extra modulator, and the exhaust manifold to EGR valve pipe is water cooled). Took about 45 mins in total, glad I did it with a cold engine as it would have been a little uncomfortable getting my fingers that close to a roasting lump !

And the difference...............pretty impressive, better pick up at low revs and less 'hunting' when idling. The EGR valve that I took off was fairly well cacked up with oily, sooty clag - a bit hard to check if it was working properly as I need a vacuum source. I've left the pipe cooler in situ, so the coolant will continue to circulate around it, and the modulators are still there, just removed the vacuum feed (there's in a T piece in the vacuum pump to brake servo line), and blanked off the spare bit of the 'T' (the blank is supplied in the D44 kit.

I'm going to run it like this for a while, and then stick the Dastek back on.

Jimbo:
Been driving around without the EGR for a few days now - it's definitely made a difference, bottom end grunt is much improved, and although I can't be certain, there seems to be less muck coming out the exhaust when giving it the boot !

Probably the best £50 I've spent in a long while  :D

bigger intacooler more cold air the better
