Re: DW's (new?) Sierra N/A PINTO race car

sorry to hear the mishaps of brands but a big well done dave
i personnaly think you have a lot to be proud of after your first year of racing.

look forward to next year especially if that short fat bloke takes his escort out too

Cheers Dan, My car may have a few scars now but i have been doing my best to get stuck in without getting contact this year. As a newbie any mistakes made are very visible so I've been trying to go as quick as possible without taking big risks. This has paid off as we only had one dnf and I've managed to prove the car works well. Next season the gloves will be off and I'll be giving it my all to beat the escorts out there, and no doubt the odd cossie too

Duncan, I don't know who you mean

Re: DW's (new?) Sierra N/A PINTO race car

BUT Going up to 3rd gear gave no further accelleration and the car lost all power. I thought I'd knocked the kill switch but everything was as it should be and after coasting off the track the engine would not restart, almost as if out of fuel.

Back in the pits we found that we had fuel, a spark and running fuel pumps but still no engine so we packed up and have now put the car back in my garage and got Andys escort out ready to start work on that for next season

found out what the cause was? Or you going to wait till the other side of winter to take a look?

Been away a couple of days, gonna start investigating tomorrow.
The main suspects are fuel pump, fuel reg, or crank sensor.

Re: DW's (new?) Sierra N/A PINTO race car

Right had a quick look at the car today to see what was stopping Linford from running. I clamped the fuel return hose first to see if the regulator had failed. Its a new part but apparently they can give up, so with the pipe clamped and probably double the necessary fuel presure I thought I'd give it a whirl. Lots of pops, bangs and flames later and although the engine seemed to want to start, nothing

Next step before swapping the fuel pump was the crank sensor. It felt solid and hadn't appeared to have moved so a quick check of the trigger wheel and... oh s##t the thing turns around and the crank aint moving

I whipped off the trigger wheel and found that the pin that locks the wheel to the crank was almost totally missing.
If you look at the pics you can see the small bit of it left on the engine and the damage marks on the wheel on the top left hole;







I poked the camera down by the crank sensor to check that it hadn't been fouling on the trigger wheel and all seems well. Looks like one problem solved



The fact that the wheel was just spinning around at will expains why every now and the then engine would try to fire as the timing would randomly be close to correct for a fraction of a second and then instantly wrong again.

The kit was a weber item and was fitted exactly as instructed but I guess its gonna need either two pins, one bigger one or a hole tapped for a small screw, I'll let Graham decide when the engine goes for its health check

Re: DW's (new?) Sierra N/A PINTO race car

Back to less serious matters with the car I removed the o/s rear window to remove more tyre marks and have now refitted it using black vinyl on the window surround in place of the neoprene insulation tape (which wasn't waterproof anyway) so that it sits more flush.

I have also replaced the heavy M6 nuts, bolts and washers with nice black plastic number plate bolts and nuts. A few more grams saved



I think it looks ok so will do the other side tomorrow.

AHEM,AHEM,isn't that what I said was wrong? How about using a diamond washer off of a zetec instead of pinning it?

Sorry Nick, I wasn't listening

I might use one of those washers and a pin to hold it in the right place while tightening it.
Whatever happens it will not only rely on one thing as it is a bit of a s##t when it ends your race early for the sake of a cheap part failing. Especially as I had you lined up for a last lap attack

Re: DW's (new?) Sierra N/A PINTO race car

odd failure really the pin shouldnt take the drive, i guess the spacer/washer that clamps the trigger wheel isnt quite right so the pin was actually taking the load instead of the bolt clamping it all up, never mind, IT WILL NOT FAIL AGAIN!

Re: DW's (new?) Sierra N/A PINTO race car

Oh well, months to build and a few hours to take apart
Inlet, TBs, battery, dry sump tank, exhaust manifold, plumbing and wiring etc all removed today.



Just the starter to remove now and then the prop, gearbox, clutch and diff can come out. Once that lot is out the engine can be lifted out with ease to go off for a freshen up

[david_white]

Re: DW's (new?) Sierra N/A PINTO race car

Well car is now minus an exhaust system, starter, gearbox, prop, clutch and a few more layers of grime.
Next is to borrow a good friends engine hoist and get the engine back to the guru's workshop for a refresh and maybe some light fettling

I need to source some green injectors (I think) as I was using Andys but apart from that virtually everything I need to be ready for 2010 will come from Burtons
