RichardAllen Posted October 6, 2008 Share Posted October 6, 2008 The EGR valve is held onto the 300TDi block with 2 hex bolts which are partly obscured by the valve and well and truly stuck in. All in all, a b*****d to remove. Before I attack the things with whatever comes to hand, does anyone have a smart wheeze for getting these bolts out ? All help appreciated Quote Link to comment Share on other sites More sharing options...
MudAllOverIt Posted October 6, 2008 Share Posted October 6, 2008 does anyone have a smart wheeze for getting these bolts out ? Complete PITA when they get stuck -- which I found both of mine were when I went to remove the EGR stuff. I ended up cutting the heads off with a hacksaw blade, then I was able to drill and re-tap. FWIW I used studs and brass nuts when I fitted the blanking plate. I've got a thermocouple mounted through the blanking plate for an EGT gauge and want to give myself at least an odds on chance of being able to get the blanking plate off easily in the future if I ever need to Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted October 6, 2008 Share Posted October 6, 2008 Go for a 10~20 miles drive first... that'll get the manifold all nice and hot. might make the bolts easier to remove. Quote Link to comment Share on other sites More sharing options...

Which be then proved as the allen head rounds off and your knuckles swiftly embed themselves upon its near magma like surface Quote Link to comment Share on other sites More sharing options...
Anderzander Posted October 7, 2008 Share Posted October 7, 2008 Get it hot, try some penetrating fluid (for what its worth!) and then use an impact driver if you can get it in? Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted October 7, 2008 Share Posted October 7, 2008 Cut the egr off with an angle grinder - that will give you more room. Then use an Allen socket rather than the angled key. Or you can cheat for the moment, leave the egr there and flatten the pipe. Quote Link to comment Share on other sites More sharing options...

Pacey Posted October 7, 2008 Share Posted October 7, 2008 Snap-on allen key, give the bugger some beans and poof it comes off. The beauty is even if you round the key Snap-on give you another. win win! Quote Link to comment Share on other sites More sharing options...
jacks906 Posted October 7, 2008 Share Posted October 7, 2008 And you mean to say? i'm guessing he is removing it to get rid of it? as it doesnt not much more than cr*p up the inside of the intake mani fold! dave Quote Link to comment Share on other sites More sharing options...
RichardAllen Posted October 7, 2008 Author Share Posted October 7, 2008 you can remove the other two bolts plate between there abit closer to the air intake and just disconnect the wiring and pipedave That's what I have done already. I just wanted to finish the job neatly and get the whole EGR out of the way. Bolts near a turbo are notorious for getting stuck, and these are not the most accessible, hence seeking help. I do racing cars. Putting exhaust gases into an inlet manifold is just plain wrong. As Carroll Smith would say, "It is a crime against humanity". The engine appears to run a little smoother too.

RichardAllen Posted October 9, 2008 Author Share Posted October 9, 2008 Any chance of a how to guide? A, I would not mind one either. This job has taken a back seat for me after taking off some checker plate placed by the previous owner onto the rear cross member, and finding out what was underneath. Or, more precisely, what was not underneath. Like most of the cross member. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted October 9, 2008 Share Posted October 9, 2008 When I had this problem I seem to remember that whacking the heads with a hammer un-stuck them quite successfully. Quote Link to comment Share on other sites More sharing options...
