The welder would be my weapon of choice as well.
The heat will help in breaking it free. Just shield the surrounding areas from spatter and you'll be fine.

To be honest I think I prefer the crank pulley removal plan. That would give me a chance to mount the trigger wheel nicely on the pulley rather than struggling to get it lined up in the car.

Got a bit more done today.   The rest of the snapped bolt had to be drilled out and it's not quite as perfect as it was before this happened but it does still have a thread in there. Lesson learned, use hardened bolts for things like this! I cleaned up the wheel and put it all back together and it started and ran fine. |

You can always helicoil it if required I suppose.

Finally got to take it for a drive up the driveway... with boost. Hahah.
I dare not really open it up as I've only got the length of the driveway to play with and don't want to go shooting out the end onto the road if something happened to the brakes.
The brakes are feeling a bit spongy although no sign of dripping fluid. No doubt all the hoses are deteriorated. Nothing has been done with the brakes for 15 years although all the parts were new when they went on so not much wear. I should pull it all apart and clean it all up and bleed the system and see how it feels after that.

I'd probably just give it a flush with new fluid and see how it feels. Could just have absorbed enough water through the breather vent over 15 years to have gone spongy. If it still feels spongy after that then have a look at hoses.
Cheapest probable culprit first!

I decided to replace the fuel pump as the old one had to be hammered back to life when I woke the car from hibernation (a couple of years ago now). I thought the fuel pump was untrustworthy so bought a new replacement.
When I went to fit the fuel pump I took the old one out of the tank and it was bone dry in there. It couldn't have been emptier. So I think some starting problems might have been caused by that.
I also bought a Turbosmart fuel pressure regulator so I can accurately set fuel pressure.

Finally had some time for it on Sunday morning. I was disappointed when the Turbosmart FPR arrived a couple of weeks ago and I tried to slot it into a spare fuel rail. It wouldn't fit! Too big! Luckily, as you can see from the picture... some modification and it was fine. The neck on the original Bosch FPR is around 7mm. This one is more like 9mm. Measuring round things and trying to tell the difference between 7mm and 9mm with my crappy Vernier callipers is challenging. I also didn't want to move too quick in case I messed something up. So I drilled out the seat in the fuel rail where the regulator slots in by going up .5mm at a time until the hole was big enough to accept the new FPR. Luckily (I use that word a lot in this case) there is enough meat in the housing for the FPR that I was able to take out around 2mm of material without any negative effect at all.  I made some new brackets to mount the fuel rail. Turbosmart, for some weird reason, have a fitting in the side of the regulator for the gauge which is totally different from any of the adapters in the common fuel pressure gauge kit you can get off eBay. So I went searching through all my boxes and found some tap connectors for kitchen taps which had the right threads. It just about worked with some PTFE tape where it joined the gauge. I set it to 3-bar at idle. What's really weird is that the engine runs really smoothly after you turn off the fuel pump. With the fuel pump running it is a bit lumpy. I think the ECU must be set up wrong for the amount of fuel required. You can set injector scaling and all kinds of weird fuel trims on this ECU. I might look at installing the air intake temperature sensor properly as that's a compensation sensor and having it hanging loose outside the intake tract might not be helping. After that I can hook it up to the laptop.   |
