skinner2k3 3 Posted April 7, 2012 I currently have the head off the 106 due to a rad full (slight exaggeration perhaps) of oil. Two questions, firstly the gasket removed was 1.5mm thick, is that the original thickness? Also other than HG or if fitted a heat exchanger splitting is there any other reason I could have oil in the rad? Share this post Link to post Share on other sites
welshpug 1,627 Posted April 7, 2012 (edited) only if someone topped up the rad with oil, standard TU5's do have a heat exchanger. there are three gaskets available for them, afaik 1.5 is standard, Sandy could confirm 209 Z0 CYL HEAD GASKET CN 0209 W3 REPAR + 0,20 0209 Z1 REPAR + 0,40 Edited April 7, 2012 by welshpug Share this post Link to post Share on other sites
skinner2k3 3 Posted April 7, 2012 Definitely not been topped up with oil No cooler or heat exchanger on this one, its a 1997 car. Will depend on the skim req then. Cheers Share this post Link to post Share on other sites
welshpug 1,627 Posted April 7, 2012 afaik all gti's had the heat exchanger Share this post Link to post Share on other sites
skinner2k3 3 Posted April 7, 2012 I may be wrong but I would be looking for a oil filter sandwich plate with two lines off to a T in the rad top hose. Unless there is another type I haven't noticed, I am sure this one does not have one, and hasn't since I have had it at least. Share this post Link to post Share on other sites

Alan_M 66 1 Cars Posted April 7, 2012 Don't TUs suffer from the oil to water ways passing at the front left corner (where the PAS pump is). Usually a tell-tale sign is if oil is leaking from here. Took me ages to flush all the oil out of mine! Share this post Link to post Share on other sites
skinner2k3 3 Posted April 8, 2012 Ah, that corner was the only part of the HG that did look knackered. There is a rubber coated metal seal there that had detached from the gasket. Share this post Link to post Share on other sites
Sandy 189 Posted April 9, 2012 Standard J4 gasket 1.35mm. Most 106 GTIs didn't have the oil/water heat exchanger bizarrely, but VTSs did, don't know why! Make sure you use the MLS gasket (multi layered steel) and NOT a composite one, there was a recall on them originally, but I think only affected cars had the change. The OE 0209Z0 is MLS.

skinner2k3 3 Posted April 9, 2012 Cheers Sandy. The gasket I removed was composite. I was planning on going to Peugeot for a new one rather than partco or similar, but will insist on an mls. If a 1.5mm was fitted I assume it's had 1 skim. Share this post Link to post Share on other sites
