Eunos 1.6 - juddering when accelerating

[toxic frog]

My wife has a 1993 Eunos Roadster,,,

After changing down a gear, the car will judder when the throttle is applied.

The local garage say that this is due to the rocker-cover gasket leaking oil which allows an accumulation of oil in the spark-plug wells, thereby fouling the plugs and leads.

They are recommending that the gasket be replaced along with the leads and plugs. They are quoting about £250 for the work due to the labour involved with cleaning the oil out of the spark-plug wells before taking the plugs themselves out.

I reckon the parts should cost no more than £50 from mx5parts, so IF this is the likely cause, I'm sure I could do the work myself.

Any thoughts?

What a load of crap !

I doubt thats the problem but if there's LOADS of oil then blow it out with an airline otherwise just remove the plug and it'll burn the oil off in the first minute.

They're ripping you off.

Rocker cover gasket is cheap to buy (MX5Parts) and easy to replace.
If there really is oil in your plug-holes then and clean out what you can with paper towels then do as Griff says and remove the plugs to drain into the chambers, it'll burn off very quickly.
£150 is a real rip-off - you could get the head gasket replaced for that price!

What has already been said. I used to suffer with plug 4 gaining oil due to the cam cover gasket design. Run some silicone around the head then put the cam cover back on, with new gasket. Never had a problem since! I have a new decent set of red 8mm silicone HT leads that I bought in preperation for my france drive, but didnt use them. Email me if you are interested.
