Valve guides source of mayonnaise

[LNM]

Further to the mayonnaise question I saw on a US site that the 103 engines can contaminate their cooling water in this manner if the guides are worn.

I'm not sure if it smokes on startup, but it does give a big gout of blue smoke when booted up to the 5K mark when at normal temp. When running normally its fine; no trickle or smoke under normal (i.e. not the lash) accelleration.

2 questions:

1. Will these have been routinely placed during a head gasket replacement?

2. Is is a turd of a job to replace them ?


Cheers in advance as always + happy new year

Your valve guides probably won?t have been replaced unless you got the head reconditioned or asked to have the valve guides done you probably wouldn?t even get the valve stem oil seals replaced unless you had the valves reground or if you asked for them to be changed. As for fitting valve guides it?s a job for an engineering shop that reconditions engines. Worn valve stem oil seals or valve guides would not cause mayonnaise, what you would get is blue smoke after the engine has being ticking over for a while then you rev it. You would also get carbon deposits in your rocker cover but certainly no mayonnaise. The mayonnaise is there because of oil and water mixture i.e. condensation with not giving the car long enough runs or lack of oil changes or cylinder head gasket. Always be sure to get the head skimmed when doing a head gasket.
Hope this helps

Cheers for info. I've not seen all the receipts yet from Road Range who did the work originally (and have done ever since new; will make interesting reading). They presumably _would_ have got the head skimmed; (more labour charges to apply you see...)

Thanks for info about valve stems - I can stop barking up that tree.

Ran it the other day + while it doesn't over heat it still seems to be over pressurising the coolant system because I got the tell tale leaks from the expansion tank behind the wheel arch again.

Ran it the next day + no leaks this time, but level dropped + I can hear squelching noises from matrix which presumably is caused by the low level.

Work continues !!
