norwichbluenose Posted January 31, 2006 Report Posted January 31, 2006 I noticed mayonaise forming on my oil filler cap. I am not losing water and the oil looks clean, power from the engine is fine. I have took the gal in for a service today and asked them to do a compression test and a chemical test for coolant in the oil. The only thing I have thought of so far is, I mostly do short journeys of 5 miles to work and the engine probably isn't up to operating temperature, I have recently done a 400 mile round trip without any problems the gal ran fine. I also I need to replace the glow plug on the smoke making machine at the back. I think that the aux heater also heats the water coolant for the air con? could this be the cause of my problems. any suggestions welcome. Hopefully it won't be expensive as my last Gal 2.8, timing chain tensioner went on that one very expensive. Andy B Quote
dipsomaniac Posted January 31, 2006 Report Posted January 31, 2006 probably condensation as you only do small journeys. you have done the right checks. Quote
norwichbluenose Posted January 31, 2006 Author Report Posted January 31, 2006 depends what you mean by the right checks Quote
dipsomaniac Posted January 31, 2006 Report Posted January 31, 2006 I was refering to the head gasket checks. If you are not losing coolant and compression checks/chemical checks were OK, I would say that you have eliminated a blown headgasket/cracked head. It is not uncommon for a small amount of mayonaise to form under the oil filler cap if you are only making short journeys. Quote
norwichbluenose Posted January 31, 2006 Author Report Posted January 31, 2006 sorry misread post.Lets hope its nothing serious and don't have sell first born to bank manager Quote
mumof4 Posted January 31, 2006 Report Posted January 31, 2006 I like that,first born.... well we got 4 to take our pick of..the 8 yr old i think will fetch the most!!lol :P Quote
johnb80 Posted January 31, 2006 Report Posted January 31, 2006 If the aux heater isn't working it will make the mayo situation worse due to very extended warm up times. If you fix the heater the mayo will probably disappear. Regards - JB Quote
norwichbluenose Posted January 31, 2006 Author Report Posted January 31, 2006 thats my guess too. catch 22 situation though cold enough to require heater, to cold to work on heater outside Quote
Masked Marauder Posted January 31, 2006 Report Posted January 31, 2006 Take it for a good long drive, if it has got worse afterwards then you have a problem, if it has cleared then it is just condenstaion. Quote
norwichbluenose Posted January 31, 2006 Author Report Posted January 31, 2006 just picked up gal chemical test and compression test ok.must be aux heater glo plug which looks a right pig to do Quote
charles Posted January 31, 2006 Report Posted January 31, 2006 check your the tube from crankcase ventilation to the airintake. this may be clogged with mayo. Quote
gregers Posted January 31, 2006 Report Posted January 31, 2006 read in auto express about this they recomened a bloody good drive with plenty of throttle,short journys are the cause. Quote
seatkid Posted January 31, 2006 Report Posted January 31, 2006 :rolleyes: What Seatkid does..... Keep the car in his (integral) garage so its always dry and at this time of year about several deg c warmer than outside when he pulls it out. Keep the heating/climate completely switched off for first 2-3 miles. This has the benefits of keeping the cabin dry and completely mist free. He does of course have electrically heated seats...Jeremy Clarkson said "who on earth would want those?". His heater pipes running under the car are insulated with foam lagging.
