Guest lynns_GTI Posted August 29, 2008 hi my head gasket has gone would it be better to go for a steel one stick to the standard one. any suggestions much appteciated thanks Share this post Link to post Share on other sites
Anthony 1,003 Posted August 29, 2008 What engine is this for? Unless you've something particularly special spec wise, a standard replacement HG is fine. Share this post Link to post Share on other sites
Guest lynns_GTI Posted August 29, 2008 It's a '89 1.6 GTI not sure exactly which engine code it is, standard engine.It's the first pug i've owned so don't know much about them really.Are the head gaskets prone to going and is there anything else i need to keep an eye on? thanks Lynn Share this post Link to post Share on other sites
Anthony 1,003 Posted August 29, 2008 Standard HG is just fine for the job then. These engines are not known for headgasket failure, but they're around 20 years old now and will have no doubt got a bit hot and/or not had the coolant changed as per the schedule, so the odd failure is to be expected. Do the job properly and ensure the head is checked for trueness and skimmed if required, and the new HG will likely outlast the car Share this post Link to post Share on other sites
nimmo 0 Posted August 29, 2008 get the valve stem seals done there prone for going and when they do go its back off with head gasket. Share this post Link to post Share on other sites
jeremy 71 Posted August 30, 2008 get the valve stem seals done there prone for going and when they do go its back off with head gasket. This is wise, as although the valve stem oil seals can be replaced with the head still on non of the garages I have asked will do it. Share this post Link to post Share on other sites

damien 22 1 Cars Posted August 31, 2008 (edited) alittle off topic but whats the main cause of head gaskets going? and what are the signs? mayo around the filler cap/missfiring/overheating? Edited August 31, 2008 by damien Share this post Link to post Share on other sites
edbar 6 Posted August 31, 2008 Mayo in the filler cap(breather) and temperature climbing at an increased rate leading to over-heating. My 309 has decided that now is a good time to demonstrate these traits! Share this post Link to post Share on other sites
large 33 Posted August 31, 2008 alittle off topic but whats the main cause of head gaskets going?and what are the signs? mayo around the filler cap/missfiring/overheating? White smoke, bubbles in the coolent, engine down on power. Heaggaskets can go at any time , I have heared of them going on new cars i.e. within the 1st 20 miles . Mind you that was a rover .

mickie 3 Posted August 31, 2008 also they like to go when your cars 20 yr old and also it doesnt help that most people dont ever flush out collant in a cars life time. look at the hg when you take it off, it'll probably be all rotten around coolant holes Share this post Link to post Share on other sites
MrG 3 Posted August 31, 2008 when they removed my head the gasket was on its last legs for sure, it was in a real bad way. Share this post Link to post Share on other sites

With a failing/failed headgasket, you might see some of the following symptoms... Unexplained loss of coolant Pressurising of the cooling system (coolant hoses going hard with engine running) Fuel smell in expansion tank White smoke from exhaust Misfire / running on 2-3 cylinders It depends largely how the gasket has failed - for example, failing between two cylinders will usually lose lots of power but potentially not effect the cooling system, whereas between a cylinder and waterway might not lose any power but will affect the cooling system. In my experience with wet-lined engines like 205 GTi's and Mi16's, you rarely end up with coolant and oil mixing - I don't recall ever seeing one with mayo in the expansion tank, and mayo in the breathers is almost normal in cold and damp conditions (especially if the car doesn't do many long journeys) and is not something to assume is related to a possible failing headgasket.

Rock Lobster 28 Posted August 31, 2008 I read a good guide to tuning the xu engine on pumaracing.co.uk, pretty good really and the guy seems to know what hes talking about. On there was a section on tightening up the head bolts, definately worth a read. Share this post Link to post Share on other sites
nimmo 0 Posted August 31, 2008 don't be fooled by the mayo under the filler cap it doesn't mean that your head gasket has gone Share this post Link to post Share on other sites

Tom Fenton 1,548 Posted September 1, 2008 A sniffer test uses a chemical to detect exhaust gasses in the coolant. If the headgasket is healthy then no exhaust gasses should be in the coolant and the chemical stays blue. If the headgasket is failing then sometimes you could get exhaust gasses in the coolant and this makes the chemical turn green/yellow. However if the gasket blows between cylinders then it will not affect the water system. Blowing between the cylinders can however be picked up with a compression test. In reality unless it is using gallons of water or overheating chronically, or running on 2 cyls with no other possible reason, then don't worry about it.

edbar 6 Posted September 1, 2008 Mine is using loads of water and temp is always high after even a minute! There is very light mayo in the breather/filler so thats fairly normal with the xu? And its pressurising the system very well indeed, need to get it sorted Share this post Link to post Share on other sites
