Corsa C pressure switch leak

[sierraman]

Had misfortune for relatives Corsa to Spring a leak last week from the pressure switch. Duly went to ECP and purchased a new switch. Fitted it and no leaks. Anyway this evening it's sprung a leak again it's pouring out of the pressure switch worse than before! My thoughts went that there is excessive pressure and sure enough there was some pale brown gunge in the breather hose resembling emulsified oil. No oil in coolant however the car is used for a 1 mile round trip every day so condensation possible. What I'm asking is have I fucked up here and got a cheap switch or is the oil in the breather causing this to reoccur? It's not blocked it's just coated the inside.

 

I'm going to clean it out at the weekend and put in a Geniune Vaux switch. Is this likely to solve this?

I would say there's more than a fighting chance that the switch you bought from ECP was total crap. They should easily be able to handle way over what the engine can produce, an condensation isn't going to make any difference.

 

From my experience with ECP is that if by some bizarre chance they actually manage to give you a part that fits, it'll be absolutely shit.

Cleaning the breather out anyway so I'm off to Pentagon to buy the OE switch Saturday. Then spend an hour cleaning up the oil off the block and undertray...

 

Might I add it hasn't seen an oil change in 39,000 miles except last year when I did it.

It'll be a duff switch as suggested above. My neighbours went in some style a few years ago, coating the bodywork and underside in oil and it used 15 litres or something ridiculous to get back from Stoke in because she just kept driving and topping it up.

The car is actually still going today!

It's a nice little motor actually, it's just a shame it doesn't get the right care. If it's like the older Cavaliers etc they used to gum up the built in gauze in the rocker cover. Might be worth a clean out.

100% definitely a crap switch. Always buy OEM. My Corsa is in its 5th or something, and the same for the radiator fan switch.

 

You've answered your own question with the gunk in the breather hose too. These engines really like to create a fucktonne of mayo from condensation in the engine not evaporating due to the temp not getting hot enough from a short journey. Not a worry until you have ladlefuls under the cam cover. That's a quick job to take off and clean out though.

What's annoyed me about it was the amount of oil that shot out of it. I'd done the job for the sister in law and because ECP couldn't provide a competently made part it's made me look a bit of a shyster. Once it's retrieved I'll be down to complain. Fuckers!!!

Unless you want like a litre of screenwash or something, you might as well pretend ECP don't exist. I remember going there years ago for a "recon" steering rack for my 106 and they handed me over one that still had twisted up copper mains cable holding one of the gaitors on and two joined up, different, rusty jubilee clips on the other - All sprayed over with matt black paint covering stickers, grease and scrapyard pen marks.

Wankers. I'd be embarrassed to serve up shit like that. But then what do you do when it's £15 for the pattern part they sell and £110 for the OE. That was the decision I had with the thermostat recently. The time it took and the fucking about, if it had leaked I wouldn't have wanted to have been the chap on the counter when I brought it back, foaming at the mouth after working blind for an hour attempting to fit one of their shit housings.

My mate had the same switch go in his 1.4 disastra H somewhere quite far away. Said he bought the biggest cheapest bottles of oil from tesco and just brimmed the block when the oil light came on and took it to a garage near home the next day. It lived fine too, still about probably

 

It's one thing the Meriva has never spat out (touch wood) yet, I had it off when I had the initial sump issues to clean the seal and generally give it some love so it better not bloody crack now
