Hint of mayonnaise in rocker cover

Post by jigarai »

I’m pretty new to all this so any advice is welcome!

Having the issues you can see in this video:

https://youtu.be/8X467JtGeJc[/url]

I decided a good place to start was to check the valve train and adjust the rockers/lifters.

Inside the right rocker cover I noticed some emulsified oil mix. Uh oh.

I’ll work out how to add a picture in a comment below in a moment.

It doesn’t burn oil. No oil in coolant reservoirs. Dipstick isn’t mayonnaisey.

So what’s the prognosis? I’m willing to have a go at most things and have enjoyed reading a number of threads on here recording people’s exploits as they undertake new challenges thinking I’d like to give that a go...

It certainly doesn't sound happy. 

When did you last do an oil change?

Hi Stesaw, thanks for your reply. The oil was changed within the last couple of months with 15-w40 mineral oil as sold by brickwerks.

Only reason I asked was to see if you had any nasties on the drain plug or mayo-oil. 
I think they can sometimes go mayo a bit in/ on the rockers with condensation.

Does the white exhaust smoke smell of coolant or fuel, as it's petrol white smoke is coolant or water getting in.  

I think the wikipage should have some info on your problem, also do a search on the forums you should find some topics that might help.
Could be coolant getting into a barrel, are your head stud nuts all there and tight? I wouldn't try and undo them, just give them a look to make sure it all looks OK and I guess you could check if they are tight, just don't go crazy on them.

It will be worth doing some basic checks anyway, picking up a cheap USB endoscope to check your lifters are all OK and take the sparkplugs out and check inside the cylinders as well as check timing, check the sparkplugs themselves along with the leads although they look new, but that doesn't mean they are OK. Again these are all just things to maybe eliminate from the equation and to check anyway. I had some rough running due to the carb not being setup right and the timing being out, but mine wasn't smoking. Could just a matter of fiddling a bit as long as you record what you do so you can revert stuff back if need be. 

How did you adjust the valves?

If you don't have a haynes manual or the bentley one, It would be best to invest in one they are very helpful.

Just giving your thread a bump, there are much more knowledgeable people on here so hopefully they might see this and pipe in!

Sounds like a cam follower isn’t fully pumping up, the smoke is linked to the misfire it’s causing , sounds to be running on 3 and the exhausts leaking, as above have you checked the valves settings, are there any loose rocker arms ? As in the hydraulic cam followers aren’t fully pumped up, a drive usually cures a lazy cam follower, I would put the mayo down to a combination of winter cold / damp air etc,( it looks like it’s just condensation) same with the exhaust, needs an hours run then check smoke running etc. Do you have all the engine tinware in place ?

Just condensation I would say from the picture on my screen 
as has been said , check the rocker arm nuts are tight and then check adjustment on the rockers
