Re: Valve timing

A10xep is a fancy version

Possibly so but tests on this engine after the chain slipping and finding the cam timing up to 90 degrees out of spec has shown that the valves/pistons have not made contact with each other. Maybe it was just luck or something to do with the 60 degrees crank throw?

Re: Valve timing

Just to update the thread... The engine is a none interference engine in which the possibility of valves/pistons contact is most unlikely. The crank journal for cylinder one when timing the engine ideally is best done by removing cylinder one spark plug and ensuring that the piston is at TDC. the cr...

Valve timing

My coleague is working on a A10 XEP three cylinder Corsa D. the valve timing jumped. Some years back AD used to advise if the engines were interference or not. I assume they are, could somebody confirm this for me please!

Re: Vauxhall Corsa 1.4 2010

Files attach; I wonder!! I read somewhere some time back about another brand pressure transducer that did not see engine vacuum? I have only just thought about this! looking at the engine cranking waveforms there is very little showing on the exhaust pockets but absolutely nothing showing on the int...

Re: Vauxhall Corsa 1.4 2010

This type of cooling system fault is quite tricky to pin down to a specific component. I did a few in-cylinder WPS tests and was not confident that I was seeing a problem. One member on here believed that I'd not got a cylinder head gasket leak, and I didn't think the engine had a cylinder head gask...

Re: Vauxhall Corsa 1.4 2010

So the car came back today. I've carried out further engine cranking tests using the WPS500x and engine idle running tests froma cold engine. Nothing stood out as far as I've seen to now, however, just letting the engine run at idle and installing a temperature gauge in the cooling system, it has no...

Re: Vauxhall Corsa 1.4 2010

Well do we want the good news or the bad? Customer came back this afternoon and said that the car has been okay since collection on the 04th November, however, the car is now broken down in Manchester and the customer showed me a picture of the reservoir hose going to the engine, which has split! I'...

Re: Vauxhall Corsa 1.4 2010

That was part of the problem though, one hose hot and the other cold and the hoses going hard as the temperature rised. Misleading me to think of a pressure rise before the coolant blow out the cap and boiled.

Re: Vauxhall Corsa 1.4 2010

Thanks, I thought I found that place when I moved into the main dealers networks, however, I was sadly wrong. When I moved back to the aftermarket garage trade initially I was okay for about 12 months, then ownership changed, and the owner having no professional training or experience on the shop fl...

Re: Vauxhall Corsa 1.4 2010

Header tank cap tend to fail on these. Thermostat wont open before boiling point at atmospheric pressure, that’s for sure. Cap ensures it remains pressurised system. Hmm. And I’m self learned, not professional trained, I guess I do above the average professional diagnostician. Not everything is abo...
