Waking up the 7


Al Crickmore

Recommended Posts

The 7 has been sitting out on my mums drive since mid-november. What precautions do I need to take to 'wake' it up? Had the battery indoors conditioning so no worries there. What else do I need to do though???

 

And yes, I know I've been slack not driving it....

There is always a difference of opinion on this. Before doing anything check all the levels, oil, water, brake and clutch (if any) fluids. Inspect underneath for heavy leakage from gearbox and diff.

 

If you can be bothered I would remove plugs and squirt a teaspoon full of 3-1 oil into each cylinder 24 hours before turning it over for the first time. Then start it at the slowest tickover it will run until the oil pressure comes up to normal. Drive off as soon as oil pressure is normal but keep the revs as low as possible (not above 3000) until it's warmed up. It will take a 20 miles run to get the oil to operating temprature such as to go to max revs.

 

But also remember to bed the brakes in before the first corner.

 

The clutch plate may be rusted to the 1st motion shaft. If so, once running smoothly, switch off, put it in 1st and start in gear and drive off. Keep pumping clutch until plate unsticks.

 

Can't think of anything else but may well have missed something.

Not sure how dry the drive is underneath the car but you might want to leave the car ticking over it until it gets to normal running temperature in order to check for coolant leaks (e.g. look directly underneath the jubilee clips).

Well do check it before you haul it out to the car - I know someone who put their Banner onto a conditioner over the winter only to find the thing was dry/knackered when he wanted to use it in the new year. And yes, I believe it was a conditioner rather than a trickle-charger...

The problem is that most of the oil will have drained away since the engine was last run. Cranking in this state can cause damage to the engine. To save any undue stress on moving components take the plugs out and crank with the injector loom plug disconnected to get oil pressure, then reconnect plug to loom and replace the spark plugs and 'da jobs a good un' *thumbup*

Roger King's advice (which has been given in this forum in the past) is not to bother with cranking with the plugs out but just to start the engine as quickly as possible.

Al - do you have weber carbs or fuel injection? Weber carbs will lose all the petrol from the float chambers and so will take a lot of cranking before they fill up and the car will start.

I've been trying over the last year to short cut this by pouring petrol into the carb via the small filter chamber. This has sometimes worked very well, sometimes had not much effect so I'm still experimenting with it.

Edited as I've realised that a lot of people now have electric fuel pumps and so don't have this problem of empty carbs - just us luddites with mechanical fuel pumps.

Sorry Al a couple of assumptions on my part.

Firstly that we are looking at a K and secondly you would know where the loom to injector multi plug is. (follow the wires from the injectors toward the bulkhead and you will come to a big black plug with 10 or so wires going into it.. It comes apart by lifting the top upward - need some pressure - when both halves will slide apart)

If you have a VX or an X flow this does not apply.

The reason for disconnecting the injector loom is to stop the injectors from squirting petrol into the cylinders whilst cranking for pressure, thus diluting what little oil that will have remained on the bores.

 

A first start after standing for a while is akin to an oil change when it can take 20 seconds or more to get oil pressure, particularly with an Apollo fitted, after a refill. It is a recognised fact that more wear takes place in the few seconds after starting the engine and I for one would prefer not to have stress on an engine in these situations. Hence cranking with the plugs removed.

 

I have paid a lot of money for my engine and cant think of any reason to jeopardise its longevity. After all it only takes 5 mins to do the whole operation.

 

As you see there are of course differing opinions about the best way. In the end its up to you!

Grant there is liitle load on an engine at tickover. It is well advised (as above - bt RK) not to turn on starter but to start as quickly as possibly and allow to tickover until pressure rises.

 

You'll be surprised how much oil will still be on the bearing surfaces and in the oil ways.

I'm taking mine for an MOT on Friday. Last run was October. Mmmmm! To faff about with plugs or just crank it? Used to live abroad and the good ole Cortina sat in the garage for up to 18 months between starts. Always intended to take out the plugs etc, but with no bread in the fridge and jet lagged just dropped it off the axle stands, unglued the clutch and cranked her. Sold the car at about 70k miles and the engine was fine even though clouds of rust coloured dust came out of the exhaust. What I did was probably quite wrong but seemed to get away with it for the best part of 11 years.
