Title: Smoking engine
Post by: vw-widow on January 08, 2022, 07:45:27 PM
Picked up Jacob’s Mk2 today, lucky for us (or unlucky) we broke down on the way home!

Sadly, in the car there is no bonnet release cable/handle, so at the moment can’t open up the bonnet; first problem.  Any ideas around this?

Oil light came on, (it was checked) stopped the car and it looked as if she was smoking 50 Marlborough at once!  Came home on recovery so going to investigate in the morning.

What a day!

Sounds like valve steam seals hopefully, cheapest fix anyway vs rings

Hopefully a cheap fix! Know more tomorrow fingers crossed.  One devastated 14 yr old at the moment:(

It could be overfilled with oil which is an easier fix.

If it wasn't smoking before the oil light came on I would prepare myself for a serious repair.

To get access spring the bonnet catch with a screwdriver through the VW badge on the grill.

Takes all of 2 seconds with this method to pop bonnet

Manage it in the end, think latch had seized bit of wd40 then pop, bonnet open.

On inspection - oil level still fine.  Noticed a leak on the block.

Rocker covers are prone to leaking

Was it smoking out the exhaust, or just from under the bonnet?
Could just be oil burning off from when it was filled up.

What was/is the colour of the smoke?
Usually there are three colours:
White (steam)- Water getting into the combustion chamber, this can be from a head gasket
Blue - Oil getting in, this can be a number of things, from stem seals to breather system blocked
Black - Fuel, usually overfueling - get the carb set up

Smoking just from bonnet.

I’m gonna say grey! Stunk of oil.


We turned the engine over for a second at home and there’s a leak here

Is it coming out of the oil pressure switch?

What you’ve circled is the coolant flange, if your circle is accurate.

Ok, if it's not coming out the exhaust, it might not be as bad as we first thought.
Sounds very much like the classic - someone missed when topping up the oil and when driving it, you've got things hot enough to start burning it off.

As for your coolant flange, does look like it's leaking, they're relatively cheap to buy new.
Don't buy just the o ring, chances are the flange is warped now.

But give it a load of wd40 every day for a few weeks before attempting the job, those bolts have a horrible knack of seizing in the head.

Whilst you are doing the flange you may wish to check the state of the metal water pipe too since they have a habit of rusting through (where it bends round the front corner of the engine. Then there is swapping the heater matrix pipes out for MK3 items but I guess you'd want to be confident the matrix has been replaced so you don't get a scolding hot leg shower...Maybe the extras are a job for summer.

Re WD40. Plusgas may be more effective?

That’s the thing above the coolant flange, with the rubber cover and wire coming from it. Pull back the cover you’ll see and electrical connection. The switch has a nut shaped base. It’s basically a bolt with a sensor in it.

Have you established it's a coolant or oil leak yet?
The oil pressure switch is to the left of the circle you've drawn with the wire attached.
Sorry didn't see Eddypeck reply.

Having another look at it today.

Coolant flange fitted no more leaks.

Engine turns over, no smoke (yet) but battery needs a good charge, as not firing the engine.

I’ll try and get a picture today, as the fuel filter doesn’t look like it’s filling!

So, battery will be charged today fully, then we can see what’s what.

Thanks to Mk2 Spares for getting the parts here so quickly.

That's odd Pierburg carbs are usually auto choke.
Though that might have just been the two Drivers I had.
