The petrol injectors have now been refurbished and are on there way back to me now.

Some of them weren’t far out at all and the worst ones weren’t even a mile out but it’s nice to know the petrol injectors are properly sorted now the LPG has been removed.

The old spark plugs had only done about 4 or 5k miles but for the sake of another £65 I thought I’d change them whilst everything was in bits as it’s all going back together new now. They’ve arrived today so that’s one less thing to arrive.

I’ve got one more part to arrive and we’re done parts wise.

I’ve not been able to get in touch with the bloke who does the thread repairs this week so I’ve been trying to think how I can drill it out.

This is the sheered bolt sticking out of the side of the block when viewed from the front passengers side of the car.

This is the view when looking through the wheel arch. Really should rust treat the front subframe too.

It’s a long long way in from the wheel arch to drill it so I’d need a long long drill bit.

After a bit of thinking I made a drill guide on the lathe…

There’s a 7mm dimple in the back of it to be an interference fit on the stud that‘s sticking out of the block. There’s then a 4mm hole right through it. It’s been superglued to the side of the block as well to help with keeping it in place. It’s long enough that it should keep the drill square as I drill the stud.

Once I’ve got a 4mm hole through the middle of the bolt I’ll remove it and take the hole in the guide up to 6mm and open the hole in the block up to 6mm. Once I’ve done that I’ll take the hole up to 8.3mm so that I can tap it and helicoil it to repair the thread that some ham fisted sod has

in the past.

Looking for a small 90 degree drill to use with the airline. If I can find something like that then I should be able to do it from the top fairly easily. Fingers crossed anyway!

I bought one of these for one job very similar to yours.
https://www.onbuy.com/gb/air-drill-angled-...p21266967/
That was two years ago and it's still in regular use, it appears to be the same as the Sealey branded version but ~1/2 price.

I'm not sure superglue will have the strength to hold your guide in place, if it was one of my jobs, I'd grind or file the remains flat, drill a bit of plate using the engine mount, or whatever is held in place by the four bolts as a template and tack a guide onto that, which you could use for both drilling and tapping. But it's your job not mine, so whatever you're happy with.

That’s the same idea as the drill I’ve ordered this evening.

It’s an interference fit on the stud that needed to be hammered on, the superglue was more for belt and braces. Normally I’d cut it flush and do it that way too but access down the side isn’t that wonderful and to see it straight on you’re working through the wheel arch.

With a bit of luck this will do the trick.

Fair enough, photo's can give a false perspective sometimes - do you have some stub drills? I find they're better for getting the cut started as they put less side load on the guide, once a couple of millimetres in past the 'point', that's when I change to a longer fast flute bit - they tend to form chips rather than lots of long swarf so take the heat away from the cutting face quicker.
I'm probably teaching granny....

Always good to hear other peoples thoughts.

I’m probably going to have to use the stub drills we’ve got due to access to be honest. There’s not much room in there trying to work between the block and the chassis leg with the dipstick tube poking up in the middle.

Done! The sheered bolt is dealt with!

Access was only possible using a 90 degree angle air drill on the airline.

The 5mm drill I was using last night did this to the bolt. There’s a slot in it as I tried to cut a slot in it and unscrew it but it was waaaaay to tight for that.

This morning I had a trip to Screwfix and bought a 5, 6, 7 and 8mm DeWalt Cobalt Drill bit. I set off with the 5mm drill bit and it went through the bolt like a hot knife through butter.

The guide I’d made for the drill kept it perfectly square and got the drill smack in the centre too.

I knocked up another guide with a 7mm hole straight through it. I then super glued this to the block and left it whilst I went for a cuppa. As there wasn’t much side to side load on the guide the superglue held it in place perfectly.

After getting the 7mm drill bit right through it I was left with this.

I got a decent thread on it that took the bolt but when trying to torque it to 25Nm it started to get loose again.

I then got the 8.3mm drill bit out and drilled it oversize, I then tapped it and put an M8 helicoil in it with thread lock on it.

That’s all of the repairs finished now.

I’ve also just won a Snap-On TechAngle Torque Wrench on eBay. These do digital torque with LED’s and sounds like a parking sensor as you’re nearing the torque limit you want. It also does digital angles too.

As soon as this arrives we’re ready for reassembly.

Excellent job on the extraction...

You've got the nice bit left now, building it all back up... Pete

Yep, nice job on the extraction - looking at the size of the torque wrench, you should be OK but watch out for going over limit when using the angle setting, I lent my small one to another tech a while back, he was doing 30Nm + 180deg. the wrench was rated at 35Nm and the +180 took it into 'fault' territory... it still passed calibration checks but had an annoying 'E1' every time it was turned on.

I've been changing inlet manifolds on my 3.6 TDV8 today, easy enough until I found one of the bolts for the OS engine mount had been cross-threaded, managed to drill & re-tap from below, still a PITA to do - not sure who to blame, production or whoever replaced the RH turbo....

Thanks for the heads up

This one goes up to 300lbft. The head bolts I think are 70Nm plus 180 degrees so hoping it should be ok.

Fingers crossed, anyway!

Since I started working on this car in January last year I’ve had to repair several threads that have been butchered by other people who have been working on the car. I guess it’s just the joys of buying a well used car!
