    Arrow YET ANOTHER EGR TOPIC:TO DRILL OR NOT TO DRILL.What do you think?.

    I had the usual issues with the EGR on my 150 so I eventually changed it and repaired the old one as per the How 2 etc. The problem now is,do I drill a hole in a new piece of kit,that is working perfectly well,so that I can squirt a regular shot of WD in there to prevent the piston seizing again?.what would YOU do?.FELIXX.

    Why drill a hole, if you are going to do it, what about blanking the EGR at the exhaust manifold, remove the EGR pipework and cooler, leave the EGR valve where it is (bolted to the manifold). Then try and get some sort of small cone filter and use a gasket and bolt it on the EGR valve, where the oval pipe would normally go? (If that makes sense ) No need to drill it.

    PS - Forget that, that was for the old one don't mutilate the new one. If it has the software update on the ECU for the new EGR valve it should be fine.

    Yea, id imagine it would just be like the manifold with the cam breather and egr.

    When I did my EGR the piston was free so I didn't need to drill the solenoid, but if I had needed to drill the valve I would have sealed the 3mm hole by tapping it to 4mm to take a small bolt. I think that leaving an open hole would allow exhaust gasses to vent to atmosphere through the piston sleeve fouling it quicker than if sealed, my EGR has evidence of gas leakage and I'd rather it wasn't down the piston sleeve!

    So what about contact cleaner or brake cleaner or anything that isn't oil based?.I just don't want it to end up like the old one,and I am in two minds and struggling with which is the best way to go.FELIXX.

    I don't think many have had the problems with the new ones as have had with the old one. Why not fit the Fiat restrictor gasket?

    I was thinking along the lines of drilling as small a hole as possible,because of this issue,and sealing it in between "sevices". Not sure of the pressures involved here though,so I was going to experiment with the old one first to see if I could achieve a happy medium. FELIXX.

    I wouldn't drill a new one!, I'm on yr 6 with my original EGR!, Semi blank if you haven't already!, Most of the problems occur when the solenoid cant work due to the other side seizing up!, My success is due to cleaning well & paying attention to the main shaft!, It travels through a ''shroud'', clean & lubricate well & often!, The solenoid end will only have to be done in years to come.
