M103 Head gasket question

[NormW126]

I notice oil seems to be coming out from the head gasket on my 300SE W126 so I'm wondering if I should have it done. Any idea how many labour hours this might be at a garage?

Also, while it's off, should I have any other stuff done?

Mine is a 1988 with just over 100k on the clock.

You will be looking at about £5-600ish at a garage I would think.

Probably worth replacing the valve stem oil seals whilst the head is off. They're cheap to buy and much easier to replace with the head off. A good old fashioned decoke - valve seats lapped wouldn't go amiss. The engine should be good for the next 23 years and you'll enjoy driving the car more knowing it's been done.

I would also go with £500-600....I had a HG done on a SL300-24v...slightly more complex engine to yours and it cost me £650

Thanks folks. I had thought about giving it a go myself. Probably just more time consuming than difficult but I'm not sure I would ever feel quite comfortable with it. Best to get the garage to have a look.

What about timing chain tensioners?
