round hole on vr engine block with major oil leak

Could you tap a small hole using self tapper screw then screw the screw in & pull out using pliers or such like,if it was bigger just tap in a flat blade screwdriver & prise out.

To replace clean up the hole,get a socket that will fit into the head of the core plug & gently tap home trying to keep it square.

not seen a new unused plug yet, that may shed some light on the best way to approach it, will call mechanic tomorrow as well see if he can recommend any thing.

the core plug may have just gone a bit rusty and has started leaking through the rust hole,

it depends on what type of core plug it is as to how you remove and re fit it, if its just a domed disk that looks like ( they are usually fitted by insering them into the hole with the middle of the dome facing out and then striking the middle of the dome so it expands the outer rim of the cap and holds itself in, they can usually be removed by denting them in with a drift or screwdriver just enough to pull the outer rim inwards.

 

if its a domed cap with a skirt around the outside that looks like [ they usually have a sharp edge around the base of the skirt, they are fitted with the dome facing inwards towards the engine and use a socket or piece of bar just smaller than the inside of the core plug to tap it in with a hammer, the only way i have seen them being removed is to use a drill just smaller than the inside of the core plug so it just weakens the part of the core plug with the sharp skirt, you can then punch a small hole in the centre of the dome and screw a self tapper into it and pull it out, although if yours is allready leaking that badly you may not even need to drill it out.

 

you could try going at it with a small drift to crumple the outer skirt inwards but you risk getting it stuck or damaging the bore of the hole.

Thanks alot thats all quite useful, is a awkward place to get at, but i'll pick up a new plug and have a go again on saturday, i'll update this thread as i get more info.

 

is it possible to push the plug right through into engine?

 

cheers

you shouldnt be able to knock it through into the engine as it should sit up against a ridge, but just be carefull not to let any loose fragments get into the engine.
