1970 Deluxe aka The Pest a very long process

I'm going to double check them John as I know it should be a simple thing to do but they haven't worked so far. They are out of the bike and been lying around for donks.
be doing that tomorrow evening i hope.

John,

The fans work brilliantly pulling plenty off air through the radiator when I tested them last night. .
Now I have to either get them working with the temp sensor or simply fit a switch so I can manually flick them on when required.

Cheers

Col, picture of sensor, if its just a switch, put it in line with +VE on fans, job done

Might be that the switch is 90 deg so woulsd likely never turn on at idle

As John says Colin, check the switch out, you can use a multimeter and some boiling water and a thermometer to see how it works.
If it simply closes at a temperature easy enough to wire this in to turn the fan on.

Well, its been a wee while since I last updated anything to do with the Pest... Simply due to me being busy rebuilding an MX-5 for my sons 18th birthday which is now ready for an MOT, the car not my son.

So the last time I had started and ran the Pest it had developed a ticking noise which when trying to diagnose it there was a clunk and engine stop/stall..
Oh dear!

After this happened I tried turning it over by hand which it did but not a full 360 degrees of rotation... An endescope was bought and shoved down all four plug holes to discover number two cylinder had a valve head sitting on top of the piston..


Not sure yet if it is an inlet or exhaust that has let go but all will be revealed once the engine is removed and head taken off.

Oh the joys....

Cheers

Damn, heck, bollox, poop the bed.....

Not Good Colin, hopefully not too much damage, not seen a snapped valve stem for a very long time and funnilly eneough never on car.

[Colimp66]

Yeh, bit of a pain that I don't need John but that's how it is.. Messing around with old stuff , never easy
If its not dropped the valve stem it certainly has dropped the valve as it shouldn't be sitting on top of the piston like it is. Will take the carbs of and the exhaust which will determine what has really happened before I remove the engine cradle to remove the engine to sort it out.

Bollocks indeed ..

Cheers

Absoluitely

here is hoping that there was enough taper on the stem to keep the spings and collects in place, you would think so but who knows.

Been out in DDG today, no more bits fell off. Forgot to bend over lock tabs and nearly lost a control arm. Poop 'appens

Hi Colin, that's a shame. Hope it's a fix you can do without too much work. MX5 looks great tho Bailey will be well pleased! See u soon

[Colimp66]

John,
I will soon see on Sunday when I get the head of seeing as we got the engine out tonight. Baillie helped me out so it didn't take long.

Keith,
Fingers crossed there's not too much damage when I open it up. Baillie is chuffed to bits with the MX5 which I'm happy about too. He did do a lot of work to it aswell which is great.
Hopefully see you either in the Pest or an MX5.


Cheers
Col.

[John A. Ross]

Here is hoping that it is not too bad, at least you got an offer on spare bits

[Colimp66]

Yeh, fingers crossed with that John.
Good of Roy to offer the parts. Top man.

Whilst it's out I will be modifying it so I can fit an electric reverse gear so it makes life easier if and when I need to reverse without getting out to push, Or more to the point when I don't have a passenger to push for me

Cheers
Col.

[John A. Ross]

Reverse gear, hatch in floorColin, fred Flinstone reverse

[Colimp66]

Awe, John,

I went and welded the hole in the floor up that the car came with when I bought it too.. If only I had a thought to myself before I did that

Cheers
Col.
