tractor exhaust i think
« on: 11 May 2010, 20:45:44 »
whilst driving home from work tonight I sank the pedal to the metal (tally tune up)and all hell broke loose.
The engine runs smooth not over heating idles silent but when reved its like I could only describe as metal rasping sound around the turbo area.
any ideas :y

Could be the EGR pipe connection with the exhaust manifold.

Could be the stainless steel EGR pipe fractured
Mine has done this twice now

I've blanked mine off at both ends with ten pence coins. No black smoke under acceleration now!

I started with two pence coins, they fit fine too, but was worried about corrosion.

The first time it went at the EGR valve end, the second was at the other. I have replaced mine on 2 occasions
What is the effect of blanking it off?? It must be there for a purpose!

not to sure about the 2.2 i'm just back from Edinburgh and the 2.5td was great cruised ok just a wee bit smokey (to much 2 stroke in fuel oops) and the mpg was a bit better.
some say the diesel does rely on the egr for cruising personaly i'll see how it runs over the next month or 2.
plus I tinkered with the boost valve turbo kicks in around 1100rpm :y
