Oily Sparks

Post by D366Y » Wed Mar 25, 2020 3:33 pm

Afternoon!!

Since I'm stuck at home I've finally had time to look at the laser - while driving it last it started making a horrible noise then cut out and refused to start again.
Took the rocker cover off and one of the valve followers (think exhaust) on the 4th piston had just fallen off. I've re-fitted it again, gapped all the valve clearances, cleaned all the spark plugs up etc. but it was still running a bit shit so I bought new sparks.

Took out the old sparks today and 1,2,3 are all sort of what I'd expected - old but cleaned up, but 4 case caked in oil.
Accordingly to the gospel of Haynes (or his book of lies depending how much you use it :lol:) this could be worn piston rings or valve guides. Seeing as the valve follower fell off I'm tempted to believe it's a valve issue but just wanted to ask how much should I be changing over, what parts should I be replacing while I'm there anyways etc?

As always your help is greatly appreciated!

Thanks
Danny

When my oil control ring went, the whole nose was oily, black and flaking and it wouldn't spark. That looks fine!

Hello D336Y,

I second what Major-Tom is suggesting.
You need to check the compression before making a decision.
They're not difficult to use.

Stay healthy.

That plug is fine....there is oil leaking from the rocker cover or elsewhere onto it. It is not an internal engine problem causing THAT oiliness.

This seems like good news!!
Thank you for replying - will get a get rocker gasket and see if that does the trick.

About the actual valve follower falling off... Any ideas on why it would decide to do that? Shall I just adjust the valve clearances again, tighten it up and leave it?

Thanks

What happened to the spring clip that holds it on?

If it was leaking wouldn't you see it dribbling down though (insert carry on joke, yak yak yak)

I would have thought I would have seen it as well but I will bow to Truck and Tom's superior knowledge!

The spring clip thing that holds the follower on was still there, but when I set the valve clearances it seemed quite loose so not sure if the spring/clip whatever is just a bit loose/old and needs replacing?

Cheers

My spring clips wobble a tiny bit from side to side. Once I replaced them with heavy duty ones.. they were much more secure. But then half of one of them turned up in my oil sump (magnetic sump plugs are worth it) so went back to standard. Think they need to have a bit of springiness, but perhaps yours have too much springiness and must be replaced?

Yeah that's sort of what I'm thinking... Will stalk the internet for some new ones and see what they do

Incidentally I have now seen the thread title a sufficient number of times that a character has been created in my processing subroutines called "Olly Sparks" bit of a creep.. bit oily.

Had exactly the same issue, albeit about 25 years ago. :?

The hardened surface of the cam follower had worn due to the spray bar being blocked. They seem to be made softer than the cam, probably to save that from excessive wear. On mine, it was concave instead of the convex curve it should have been.
So I would be getting that cover off and checking every single follower for wear.
The fact it is near the far end of the spray bar suggests the bar is filling up with crud and the holes are blocking from the ends first, given that the oil enters the bar in the middle.
If you are not already changing the spray bar at regular intervals then start doing that now.
If you are already changing the spray bar then you need to start asking yourself where the crud has come from to block it.

One final point, block all the oil drain holes in the head before you undo the spray bar bolts. They fit perfectly down the holes if you drop them. Ask me how I know!!!

You can leave out the beasts, but debauched tales of fornication, alcohol and breasts would be most welcome.
