Intercooler top pipe/hose.

Evening people ...

Quick question ... took a quick look under the bonnet of my fairly new (to me) 200Tdi 110 CSW today to see if I could see any obvious reasons why it seems to be a bit low on power. On checking all pipes and hoses I noticed that there was a small hole in the top of the metal intercooler pipe about six inches from the intercooler. Now I would have thought that this shouldn't be there but, the reason for me asking, is that the hole is about 4mm round and looks too neat ... almost like it was drilled by someone.

Can anyone shed any light on this please? My old 200tdi 90 certainly didn't have this hole ... I don't think

May have been used for a boost gauge or something in the past and the bung has come out

Would that have been as small as 4mm though chap? ... I've put a blob of silicon in it to seal it for now but yet to see if it's made a difference

bung the hole back up , should be back to full power

I've put a blob of silicon in there while I was sealing my new chequer plate ... do you think that will be ok or is it likely to get sucked in?

It'll get blown out if anything, how about a hose clip round it, that should cover the hole

Think I'll play it safe fella ... a self tapper with a hose clip around it

Thanks for your help

How about a new hose?

Well that's the next thing but being as it's the metal one it should be easy enough to seal ... I wanted to know if it was going to make a difference first

.15 of an inch no idea what that is in fractions

put a blob of tig weld on there if its stainless if not a screw and some high temp silicone

Actually I've got a MIG welder but I think a self tapper will suffice or even some chemical metal paste

As long as it holds up to 25 psi your grand I'd say a small mid dot if its steel the just paint over simples
